FOREWORD

The Agency for Toxic Substances and Disease Registry A TSDR was established by Congress in 1980 under the Comprehensive Environmental Response Compensation and Liability Act also known as the Superfund law This law set up a fund to identify and clean up our countrys hazardous waste sites The Environmental Protection Agency EPA and the individual states regulate the investigation and clean up of the sites

Since 1986 A TSDR bas been required by law to conduct a public health assessment at each of the sites on the EPA National Priorities List The aim ofthese evaluations is to find out if people are being exposed to hazardous substances and if so whether that exposure is harmful and should be stopped or reduced If appropriate ATSDR also conducts public health assessments when petitioned by concerned individuals Public health assessments are carried out by environmental and health scientists from ATSDR and from the states with which ATSDR has cooperative agreements The public health assessment program allows the scientists flexibility in the format or structure of their response to the public health issues at hazardous waste sites For example a public health assessment could be one document or it could be a compilation of several health consultations the structure may vary from site to site Nevertheless the public health assessment process is not considered complete until the public health issues at the site are addressed

Exposure As the first step in the evaluation A TSDR scientists review environmental data to see how much contamination is at a site where it is and how people might come into contact with it Generally A TSDR does not collect its own environmental sampling data but reviews information provided by EPA other government agencies businesses and the public When there is not enough environmental information available the report will indicate what further sampling data is needed

Health Effects If the review of the environmental data shows that people have or could come into contact with hazardous substances ATSDR scientists evaluate whether or not these contacts may result in hannful effects ATSDR recognizes that children because of their play activities and their growing bodies may be more vulnerable to these effects As a policy unless data are available to suggest otherwise A TSDR considers children to be more sensitive and vulnerable to hazardous substances Thus the health impact to the children is considered frrst when evaluating the health threat to a community The health impacts to other high risk groups within the community (such as the elderly chronically ill and people engaging in high risk practices) also receive special attention during the evaluation

A TSDR uses existing scientific information which can include the results of medical toxicologic and epidemiologic studies and the data collected in disease registries to determine the health effects that may result from exposures The science of environmental health is still developing and sometimes scientific information on the health effects of certain substances is not available When this is so the report will suggest what further public health actions are needed

Conclusions The report presents conclusions about the public health threat if any posed by a site When health threats have been determined for high risk groups (such as children elderly chronically ill and people engaging in high risk practices) they will be summarized in the conclusion section of the report Ways to stop or reduce exposure will then be recommended in the public health action plan

A TSDR is primarily an advisory agency so usually these reports identify what actions are appropriate to be undertaken by EPA other responsible parties or the research or education divisions of A TSDR However if there is an urgent health threat A TSDR can issue a public health advisory warning people of the danger A TSDR can also authorize health education or pilot studies of health effects fullscale epidemiology studies disease registries surveillance studies or research on specific hazardous substances

Community ATSDR also needs to learn what people in the area know about the site and what concerns they may have about its impact on their health Consequently throughout the evaluation process A TSDR actively gathers information and comments from the people who live or work near a site including residents of the area civic leaders health professionals and community groups To ensure that the report responds to the communitys health concerns an early version is also distributed to the public for their comments All the comments received from the public are responded to in the final version of the report

Comments If after reading this report you have questions or comments we encourage you to send them to us

OLD WU MINGTON ROAD PUBLIC HEALTII ASSESSMENT FINAL RELEASE

A SUMMARY

The Old Wilmington Road Site is a public health hazard because of long term exposure to hazardous substances in groundwater Exposure to chlorinated sol vents is occurring and has occurred by ingestion of drinking water dermal absorption and inhalation of contaminants in vapors and aerosols However private well sampling data are not sufficient to identify everyone who may be using contaminated groundwater and to confirm whether the contaminants at levels of health concern are present in each supply well Based upon existing data groundwater is the only medium through which site contaminants are reaching area residents

The Pennsylvania Department of Health (DOH) and the Agency for Toxic Substances and Disease Registry (ATSDR) prepared a Health Consultation for the site (then Perry Phillips Landfill) in June 1999 That document concluded that the site was a public health hazard and recommended more groundwater sampling installation of additional home filters and public health education to residents along Ash Road

B PURPOSE AND HEALTH ISSUES

The Environmental Protection Agency (EPA) proposed the Old Wilmington Road site (OWR) for listing on the National Priority List (NPL) of hazardous waste sites on July 22 1999 The site was listed on February 4 2000 Federal law mandates that sites proposed to the NPL receive a public health assessment within one year of proposed listing Accordingly the DOH and the ATSDR have evaluated the site for adverse health effects posed by hazardous chemicals in and near a closed landfill and other suspected disposal areas After three visits and interviews with local citizens no one has expressed any community health concerns about the site This is probably because the EPA has already furnished carbon filtration units to six homes and kept the citizenry informed of site conditions and future sampling plans

C BACKGROUND

Demographics

The Old Wilmington Road site (the site) is on Old Wilmington Road one mile north of US Route 30 in Sadsburyville Chester County Pennsylvania (Figures 1 and 2) The site is unfenced and the area around the site is a mix of farmland and rural residential subdivisions Bordering the site to the north is a residential development of newer homes (1990s) and to the south are open fields pasture land and more residences (Figure 3) Based upon 1990 census data about 300 people live within a one-half mile radius of the site There are no schools nursing homes or other public institutions within this geographic area

OLD WILMINGTON ROAD PUBLIC HEALTH ASSESSMENT FINAL RELEASE

Site Description and History

The site consists of at least four separate areas~ an unlined unpermitted closed landfill (Area 1) a general disposal area (sewage sludge demolition waSte scrap metal) and junkyard still operated as a business (Area 2) an area of suspected solvent dumping up gradient of the landfill (Area 3) and an area of suspected solvent dumping on the east side of Old Wilmington Road (Area 4) (Figure 4) Under legal and regulatory pressures from the Pennsylvania Department of Environmental Protection (PADEP) and the Chester County Health Department (CCHD) Area 1 was closed and capped in 1987 after some 15 years of illegal operation (1) The owner of the site supplies water to a mobile home park he owns (Figure 2) from a contaminated well on his property However the well has been fitted with an approved filtration system that removes harmful chemicals (volatile organic compounds or VOCs) from the water before it is served to customers The owners private well and five others in the area are also treated with carbon filter units (Figure 4) that were first installed in 1994 by the EPA The evidence from private well sampling suggests that groundwater contamination extends no farther than one-half mile down gradient from the site

In 1988 the EPA contractors began site inspections and sampling that included surface water and sediment from a marshy area (Figure 5) soil samples in Areas 1 and middot2 (Figures 5 and 6) and water from six nearby private wells (1 and Figure 7) Samples were analyzed for metals (Target Analyte List) and Target Compound Ust parameters including volatile and semi-volatile compounds pesticides and PCBs according to the EPA protocols Tables 1 to 3 list those parameters the detection limits and the instrumentation used Air quality monitoring was not performed presumably because the landfill is closed and capped

Eleven soil samples (S-1 through S-10 Figures 5 and 6) were collected at points representative of surficial site conditions Samples were composited from auger borings to a maximum depth of 3 feet (1) No hazardous chemicals were detected at levels harmful to site workers or visitors For example VOCs were detected in the low parts per billion range and the maximum lead concentration did not exceed 400 mglkg (parts per million) 100 mglkg less than Pennsylvanias residential lead cleanup standard under Act 2 (4) One sediment and one surface water sample collected in the marshy area contained only trace amounts of hazardous chemicals Therefore based upon existing data we may eliminate surface water sediment and soil as elements in potential exposure pathways for area residents

When wells HW -1 and HW -11 indicated elevated VOCs (Table 4 ) the groundwater investigation was expanded in 1994 and later years to include monitoring well construction in all four Areas(3) and more residential well sampling (Figures 4 8-13) The EPA soon learned that groundwater contamination had spread to off-site areas as explained below

Figures 8 through 12 depict three areas where the EPA consultant believes chlorinated solvents were disposed The contaminants of concern are tetrachloroethene (PCE) trichloroethene

(TCE) 11-dichloroethane (DCA) 111-trichloroethane (TCA) and 11-dichloroethene (DCE) The figures show contamination contours for the most recent (1996) data for which isocon maps have been prepared Contours should be considered as approximations because they are largely based on interpolation between a few data points Note that private wells monitoring wells or both show marked increases in concentrations on the Butler property (Area 3) (up gradient) Perry Phillips property (Area 1) and Roger Phillips property (Area 4)(crossgradient from Area 1) Groundwater plumes have developed topographically down gradient from three of the four potential source areas (Figures 4 and 13) Plumes are identified by their differentiating chemical constituents particularly as they impact private wells We are unsure how long the Area 3 and Area 4 contaminant sources have existed We are also unsure how long residents in the area were exposed to contaminants before the EPA installed filters The Perry Phillips private well (not the mobile home park well) contained PCE at varying concentrations over time reaching an apparent maximum concentration of 1000 parts per billion (ppb) in 1993 (3)

In 1998 the EPA contractors performed three sampling rounds for approximately 35 domestic wells down gradient of the site(s) and north of the power line (Figures 2 and 4) The home locations and sampling results are shown for all wells that indicated a contaminant concentration of 1 ppb or higher for any contaminant detected during the most recent area wide sampling (December 1998) Clearly wells down gradient of the suspected source at Area 4 have the highest concentrations Two home wells on Ash Road with PCE concentrations above the EPAs maximum contaminant level (MCL) for drinking water(S ppb) are still operating without approved filters (Figure 4)

In May and September of 1999 the EPA contractor sampled five of the six homes with filters an unfiltered home on Ash Road (29 ppb PCE and the home well on Debbie Drive (Figures 3 and 4) There were no appreciable changes in contaminant concentrations except for the home on Ash Road which reported a decrease in PCE concentration from 29 ppb to 8 ppb (Figure 4) The home on Debbie Drive is up gradient of all plumes and therefore non-detect for all parameters Plume boundaries appear to have stabilized (steady state conditions) and should not change for at least several years unless there is more uncontrolled dumping of mobile contaminants in the suspected source areas

Site Visits

On January 26 1999 the DOH hydrogeologist J E Godfrey met with a representative of the CCHD and toured the site and surrounding area The landfill has been inactive for years but Area 2 (Figures 2 and 13) still contains junk mobile homes scrap metal drums and miscellaneous debris The scrap yard owneroperator has posted a sign near the office entrance warning trespassers to keep out The residential area of new homes (Debbie Drive) is up gradient of Areas 1 2 and 3 (Figure 3) and will not be affected by site-related groundwater contaminants Surprisingly home wells on Karen Circle immediately down gradient of the junkyard show no

groundwater contamination There is one vacant lot on Karen Circle down gradient of the junkyard where a new well could be drilled if the lot is developed residentially

On February 22 1999 Mr Godfrey again visited the site with two EPA representatives The investigators verified the location of rock types shown on the geologic map of the Parkesburg quadrangle (Figure 14) plotted new homes and other structures on a topographic map and met with an area resident who provided useful historical information While visiting that residents property (which is located behind Area 4 (Figure 4)) investigators found one empty oil container and one plastic jug partly filled with what appeared to be waste oil or other liquid Both items were down gradient of MW -3 (Figure 13)

On January 14 2000 Mr Godfrey and Mark Lavin of the DOH visited the site with two representatives from Region 3 EPA The site has changed very little since the earlier visits Mr Lavin further edited and fine tuned existing topographic maps to correctly portray area features such as monitoring wells and homes

D DISCUSSION

Pathways Analysis

To determine whether nearby residents are exposed to contaminants migrating from the site the DOH evaluates the environmental and human components that lead to human exposure An exposure pathway consists of five elements (a) a source of contamination (b) an environmental medium in which the contaminants may be present or may migrate (c) a geographic point of human exposure (d) a biologic route of exposure and (e) a receptor population

The DOH and the ATSDR identify exposure pathways as completed middotpotential or eliminated In completed exposure pathways the five elements exist and so exposure has occurred is occurring or will occur In potential exposure pathways however at least one of the five elements is missing and exposure to a contaminant could have occurred in the past or could occur in the future An exposure pathway can be eliminated if at least one of the five elements is missing and will never be present As previously stated we have eliminated surface water soil and sediment as elements in potential exposure pathways at this site

The contaminant plumes from the Old Wilmington Road site present a complex hydrogeological and human exposure problem for investigators and groundwater users Figure 10 shows that the plumes are for the most part topographically controlled A significant geological factor is the tabular intrusion (dike) of pegmatite shown on the geologic map of the Parkesburg quadrangle (Figure 14) and also indicated on Figures 4 and 13

f


Pegmatite is a coarse-grained igneous rock of granitic composition When intruded into surrounding rock fractures may be created or enlarged along it such that they become preferential pathways for groundwater movement Figure 13 illustrates one possible mechanism whereby contaminants from Area 3 could have migrated slightly crossgradient along the dike to MW-4 and further down slope toward the two homes on Karen Circle (Figure 4) MW-4 and the homes contain low levels of DCA and TCA both characteristic contaminants of Area 3 (1 and Figure 12) Part of the Area 3 plume also moves down gradient and merges with the Area 1 plume which is primarily a PCE plume (Figure 13)

The plume from Area 1 extends topographically down gradient and misses nearly every home thus explaining the non-detect results from residential wells along Old Wilmington Road and the southern part of Karen Circle (Figures 4 and 13) Because the landfill is closed its plume is probably in steady state (not changing with time) and may never affect more (existing) domestic wells However more sampling rounds are needed in that area to confirm the plumes position Monitoring wells may also be required near the power line right-of-way east of Old Wilmington Road (Figures 2 and 4) The ends of the Area 2 and Area 3 plumes are indicated as uncertain in Figure 13 due to a lack of data points in that region of the map which is mostly agricultural land

The plume(s) extending down gradient from Area 4 present a more challenging problem MW-3 (Figure 13) which was constructed to monitor the up gradient part of the Area 4 plume consistently indicates significant concentrations of every contaminant of concern except PCE (trace amount only until1997 (2)) However three homes along Ash Road down gradient of MW-3 contain 29 ppb (maximum) 22 ppb (before filter) and 8 ppb PCE respectively Another property on Ash Road which is fitted with a carbon filter unit has the highest PCE concentration in unfiltered water (104 ppb January 1997) east of Old Wilmington Road That residence appears to be near the middle of the PCE plume from Area 4 (Figures 4 and 13) Furthermore PCE levels have increased since 1996 (2) Those data strongly suggest that there is yet another source (or sources) of PCE contamination between MW-3 and the Ash Road wells As stated previously investigators noted evidence of dumping in woods behind Area 4 during the February 22 1999 site visit Investigators also saw several large trucks parked on Area 4 on the January 12 2000 visit More investigation and perhaps more monitoring wells will be required to resolve the contaminant source issue there We have found no evidence to indicate that any plume crosses Old Wilmington Road (Figure 13)

Toxicological Evaluation of Past Exposures

In this section DOH discusses the health effects that may occur in persons exposed to site related contaminants

The ATSDR has developed health-based comparison values (CVs) that are chemical-specific concentrations which determine environmental contaminants of health concern We use CVs to determine which contaminants require further evaluation These values include Environmental

OLD WILMINGTON ROAD PUBLIC HEALTH ASSESSMENT FINAL RELEAS

Media Evaluation Guides (EMEGs) and Reference Dose Media Evaluation Guides (RMEGs) f noncancerous health effects and Cancer Risk Evaluation Guides (CREGS) for cancerous health effects H environmental media guides cannot be established because of a lack of available health data other comparison values may be used to select a contaminant for further evaluation

In this section the DOH discusses health effects that could result from site-related contaminant exposures assuming they occurred for 20 years between 1974 and 1994 Twenty years is a reasonable estimate of exposure duration It is based on the start of operations and adjusted to allow time for migration of contaminants through groundwater To determine the possible heal effects of site-specific chemicals the DOH researches scientific literature and uses the ATSDR minimal risk levels (MRLs) the EPAs reference doses (RIDs) and the EPAs Cancer Slope Factors (CSFs) MRLs are estimates of daily exposure to contaminants below which noncancerous adverse health effects are unlikely to occur RIDs are estimates (with uncertainty spanning perhaps an order of magnitude) of daily oral exposures in milligrams per kilogram pe day (mglkgday) to the general public (including sensitive groups) that is likely to be without at appreciable risk of noncancerous hannful effects during a lifetime (70 years) When RIDs and MRLs are not available a no observed adverse effect level (NOAEL) or lowest observed advers effect level (LOAEL) may be used to estimate levels below which no adverse health effects (noncancerous) are expected

Health guidelines such as MRLs and RIDs however do not consider the risk of developing cancer To evaluate exposure to carcinogens EPA has established CSFs for inhalation and ingestion that define the relationship between exposure doses and the likelihood of an increased risk of cancer compared with controls that have not been exposed to the chemical Usually derived from animal or occupational studies cancer slope factors are used to calculate the exposure dose likely to result in one excess cancer case per one million persons exposed over a lifetime (70 years)

Because children generally receive higher doses of contaminants than adults under similar middot circumstances the DOH uses the higher doses in forming its conclusions about the health effects

of exposures to site-related contaminants when children are known or thought to be involved (se Child Health Initiative section) Also readers should note that researchers conduct animal studies using doses at levels much higher than those experienced by most people exposed to contaminated groundwater originating from hazardous waste sites

111-trichloroethane (TCA)

The highest level of 111-trichloroethane (TCA) found in home wells near the site was 90 micrograms per liter (pgL) Since that value does not exceed any of ATSDRs comparison values DOH will not discuss it further in this document

6


11-dichloroethane (DCA)

The highest level of 11-dichloroethane (DCA) found in home wells near the site was 5 pgL The ATSDR does not have any comparison values for DCA However the estimated oral exposure dose is several thousand times lower than the level at which health effects were observed in animals (eg decreased body weight) Therefore noncancerous health effects are not expected to occur in the exposed population by oral as well as dermal and inhalation routes The EPA does not have a CSF for DCA but has classified it as a possible human carcinogen based on no human data and limited evidence of carcinogenicity in two animal species (rats and mice) (5) However our estimated exposure is several thousand times lower than the level at which cancer was observed in animals At present there are no epidemiological studies available regarding the carcinogenic effect of DCA Based on animal studies the level of exposure poses an insignificant cancer risk to people

Tetrachloroethylene (PCE)

Description Uses and Occurrences

PCB is a manufactured chemical that is widely used for dry cleaning of fabrics and for metalshydegreasing It is also used to make other chemicals and is used in some consumer products Other names for PCE include perchloroethylene and tetrachloroethene It is a nonflammable liquid at room temperature It evaporates easily into the air and has a sharp sweet odor Most people can smell PCE when it is present in the air at a level of 1 part PCE per million parts of air (1 ppm) or more although some can smell it at even lower levels Much of the PCE that gets into water or soil evaporates into the air Microorganisms can break down some of the PCE in soil or underground water In the air it is broken down by sunlight into other chemicals or brought back to the soil and water by rain It does not appear to collect in fish or other animals that live in water (6)

Noncarcinogenic Health Effects

For short periods (acute) and using the assumption that children living near the site consumed one liter of water per day contaminated with PCE at a maximum level of 1000 pgL the DOH believes that those children might have experienced noncancerous adverse health effects (eg hyperactivity) The estimated dose of exposure for children at that level would exceed the ATSDRs acute oral MRL (14 days and less) by a factor of (two) 2 For adults estimated exposure dose would be lower than the acute MRL Therefore adults would not have experienced noncancerous health effects The ATSDR selected their acute oral MRL based on a study that showed developmental neurotoxicity (ie bull significant increases in locomotion and total activity) in laboratory mice exposed at a dose of about 50 times the level of child exposure estimated by the DOH (6)

7

-- ------~---------------


For longer periods (chronic) and using the same assumption as above the DOH believes that those children might have experienced noncancerous adverse health effects (eg hyperactivity) but not adults The nervous system is a well-established target of PCE exposure in humans but longer term oral studies in animals have not focused on neurological effects (6) The EPA selected their oral RID based on a study that showed liver toxicity in laboratory mice exposed at a dose of about 260 times the level of child exposure estimated by the DOH (7)

Carcinogenic Health Effects

Some epidemiological studies of dry cleaning workers suggest a possible association between long-term high inhalation exposure to PCE and increased cancer risk However the results of these studies are inconclusive because of the likelihood that the study population was exposed to petroleum solvents at the same time In another study in New Jersey PCE contamination of the drinking water was associated with an increased incidence of non-Burkitts high grade nonshyHodgkin s lymphoma in females Many of the water supplies were also contaminated with TCE making it difficult to assess the relative contribution of each chemical (6) Results of animal studies conducted with amounts much higher than those that most people are exposed to show that PCE can cause liver and kidney cancers Although it has not been shown to cause cancer in people US Department of Health and Human Services has determined that PCE may reasonably be anticipated to be a carcinogen The International Agency for Research on cancer (IRA C) has determined that PCE is probably carcinogenic to humans (6)

In order to evaluate the possible cancer risk associated with the exposures to PCE at the maximum concentration (1000 pgL) that occurred to people who used contaminated groundwater via multiple routes (inhalation ingestion dermal) for 20 years we calculated the theoretical cancer risk using the CSF of (0052 ~glkglday)1 that EPA has placed under review (3) These calculations are based on the assumption that there is no safe level of exposure to a chemical that causes cancer and also assuming that the inhalation and dermal doses are approximately equal to the estimated ingestion dose However these calculated risks are not real and tend to overestimate the risk associated with exposures that occurred Based on theoretical cancer risk estimation for past exposures the predicted cancer occurrence would be about one ( 1) cancer per 1000 people It is our opinion that past exposure to PCE poses moderate cancer risk for those people

Trichloroethylene (TCE)

Description Uses and Occurrence

TCE is a nonflammable colorless liquid with a somewhat sweet odor and a sweet burning taste It is used mainly as a solvent to remove grease from metal parts but it is also an ingredient in adhesives paint removers typewriter correction fluids and spot removers TCE is not thought to occur naturally in the environment However it i~ present in some underground water sources

8


and many surface waters as a result of the manufacture use and disposal of the chemical TCE does not build up significantly in plants and animals which includes humans (8)


For acute exposure and using the assumption that children living near the site consumed one liter of water per day contaminated with TCE at a level of 530 JLgL the DOH believes that those children would not have experienced noncancerous adverse health effects The dose experienced at that level is Jess than the ATSDRs acute oral MRL (14 days and less) by a factor of (four) 4

For chronic exposure the ATSDR has not developed a chronic oral MRL for TCE (8) The EPA has placed the RID for TCE under review and therefore an RID is not available at this writing (9) However noncancerous health effects are not expected when multiple exposure routes (inhalation ingestion and dermal contact) are evaluated Assuming that the inhalation dose and dermal dose are approximately equal to the ingestion dose the respective doses for children and adults would be three times the ingestion dose The total dose for children and adult would be 0159 and 0045 mglkglday respectively The total doses are several hundred times below doses at which adverse health effects would be expected based on animal studies Therefore noncancerous health effects would not be expected


In studies using high doses of TCE in animals tumors in the lungs liver and testes were found providing some evidence that a high dose of TCE can cause cancer in experimental animals (8) Based on the limited data in humans regarding TCE exposure and cancer and evidence that high doses of TCE can cause cancer in animals the ARC has determined that TCE is probably carcinogenic to humans Recently the Department of Health and Human Services (National Toxicology Program) determined that TCE may reasonably be anticipated to be a carcinogen This was based on limited evidence from studies in humans sufficient evidence of malignant tumor formation in experimental animals and convincing relevant information that TCE acts through mechanisms indicating it would likely cause cancer in humans Currently the National Toxicology Program is reviewing TCE for upgrading it to a known human carcinogen The EPA has placed TCE under review as to its carcinogenicity Epidemiological data are limited for evaluating the carcinogenicity of TCE in humans Studies have suggested that occupational exposure to TCE causes cancer of the liver biliary tract and also non-Hodgkin s lymphoma Another study has indicated that occupational exposure to TCE has been associated with cancer of the kidneys

In order to evaluate the possible cancer risk associated with the exposures to TCE at the maximum concentration (530 JLgL that occurred tomiddotpeople who used contaminated groundwater we calculated the theoretical cancer risk using the CSF of (0011 rnglkgldayr1

that EPA has placed under review These calculations are based on the assumption that there is no safe level of exposure to a chemical that may cause cancer and also assuming that inhalation and dermal doses are approximately equal to the estimated ingestion dose However these calculated risks are not real and tend to overestimate the risk associated with exposures that occurred Based on theoretical cancer risk estimation the predicted cancer occurrence would be about one cancer per 10000 people It is our opinion that the past exposure to TCE poses low cancer risk for those people

Dicbloroethene (DCE)


DCE also known as 11-dichloroethylene and vinylidene chloride is a chemical used to make certain plastics and flame-retardant coating for fiber and carpet backing It is a colorless liquid that evaporates quickly at room temperature It has a mild sweet smell and bums quickly It is a man-made chemical and is not found naturally in the environment Most of the DCE manufactured is used to make other substances or products such as polyvinylidene chloride (10)


The highest level of DCE found near the site (5 JLgL) does not exceed any of the ATSDRs comparison values for DCE Therefore DOH believes that people exposed to that level of DCE would not have experienced noncancerous adverse health effects


The EPA has determined that DCE is a possiblC human carcinogen Studies on workers who breathed DCE have not shown an increase in cancer These studies however are not conclusive because of the small numbers of workers and the short time studied Animal studies have shown mixed results Several studies reported an increase in tumors in rats and mice and other studies reported no such effects (ll) The DHHS has not classified DCE with respect to carcinogenicity The IARC has determined that DCE is not classifiable as to its carcinogenicity in humans ( 1 0)

The EPA has established a CSF of (06 mglkglday)1 for DCE (12) PADOH used the CSF for DCE to evaluate an increased cancer risk Based on the theoretical cancer risk estimation for past exposures the predicted cancer occurrence would be about seven (7) cancers per 100000 people However these calculated risks are not real and tend to overestimate the risk associated with past exposure to DCE It is our opinion that past exposure to DCE poses a minimum cancer risk for those people

For PCE the ATSDR has not developed a chronic oral MRL However the EPA has developed a chronic oral RID of 001 mglkgday for noncancerous health effects based on liver toxicity in animal studies (6) The residents are exposed to PCE in their well water (maximum concentration of 29 pgL) by ingestion inhalation and dermal contact The estimated exposure dose by ingestion would be 00008 mglkgday Assuming that inhalation dose and dermal dose from bathing may be approximately equal to the estimated ingestion dose the estimated dose would be three times that of the ingestion dose The total dose is below the chronic ingestion RID of OOlmgkgday Therefore noncancerous health effects are not expected for adults from exposure to PCE at this concentration Also for children noncancerous health effects are not expected because the estimated exposure dose would be less than the oral RID

Currently the ATSDR has not established a CREG for PCE However based on the EPAs previous CSF for PCE the use of well water at a concentration of 29 pgL (Ash Road) would result in a low risk of developing cancer over a lifetime People using well water at a level of 8 ppb (another Ash Road residence) have no apparent increased risk of developing cancer over a lifetime

Exposure to chlorinated solvents is still occurring in at least two of the three homes It is a prudent public health practice for the residents of those homes to use alternate sources of uncontaminated water or treat the current water supply to prevent further exposure

Health Outcome Data Evaluation

Based on the available exposure information residents of the three homes on Ash Road with PCE levels above the MCL may have been exposed to elevated levels of chlorinated solvents The Commonwealth of Pennsylvania maintains health outcome databases including vital statistics and the cancer registry These databases provide information on total mortality cancer morbidity and birth defects However only a small number of residents near the site used the contaminated private wells Therefore the data that are available in the Commonwealth database do not allow us to determine whether certain adverse health outcomes would be related to exposure Additionally there were no community concerns associated with morbidity and mortality among the residents Therefore no health outcome data are evaluated at this time

Child Health Initiative

The ATSDR and the DOH recognize that children are especially sensitive when exposed to many contaminants For that reason we based all our exposure scenarios and conclusions on the results of childrens exposure to site-related contaminants at Old Wilmington Road and discussed those scenarios in the preceding Toxicological Evaluation section of this report

OLD WILMINGTON ROAD PUBLIC HEAL Til ASSESSMENT FINAL RELEASE

Since the scrap yard part of the site is still operated as a business and is posted with no trespassing signs we do not expect children to visit the site unsupervised Therefore children are not at risk from the physical hazards (falling debris etc) normally associated with moving storing or selling scrap iron steel drums or other miscellaneous equipment

E COMMUNITY HEALTH CONCERNS

No community health concerns have been presented by any individual or any citizens groups to the DOH or the ATSDR regarding the Old Wilmington Road Site We visited with residents in one home with a contaminated well (now filtered) but they expressed no health concerns However the Chester County Health Department took legal action beginning February 28 2000 against the mobile home park owner for a malfunctioning septic system (oral communication with the EPA) Additionally no comments were received when this document was released for public comment middot

F CONCLUSIONS

l From the information received the DOH and the ATSDR consider the site and other nearby sources of VOCs to be a public he~th hazard because of long term exposure to hazardous substances in groundwater Exposure to chlorinated solvents is occurring and has occurred by ingestion of drinking water dermal absorption and inhalation of contaminants in vapors and aerosols However private well sampling data are not sufficient to identify everyone who may be using contaminated groundwater and to confirm whether the contaminants at levels of health concern are present in each supply well We are particularly concerned that VOCs have increased in some wells in the past three to four years

middot 2 Home wells on Karen Circle down gradient from Area 3 indicating very low VOC levels do not pose a health risk at this time for those consuming or showering in the water

3 Use of private well water on Ash Road (29 ppb PCE) over the course of a lifetime could slightly increase the risk of cancer

G RECOI1l1ENDATIONS

l Sample private wells and monitoring wells on and downgradient of the three contaminant source areas (sites) and north of the power line right-of-way for at least three more consecutive calendar quarters

2 Provide the affected homes on Ash Road with approved filtration systems

12


3 Provide public health education to residents on Ash Road The DOH will follow-up on this activity

4 The DOH the ATSDR and the EPA will collaboratively evaluate future site data as the EPAs expanded groundwater sampling and investigation of the site continues

H PUBLIC HEALTH ACTION PLAN

The EPA is in the early stage of site evaluation and a draft Remedial Investigation Feasibility Study (RJIFS) has been prepared More well water sampling is planned and the DOH the ATSDR and the EPA will work together to educate citizens about the meaning of sample results If new data reveal that site conditions are different than previously thought or have changed over time the DOH and the ATSDR may reevaluate conclusions and recommendations stated in this report

p

OLD wnMJNGTON ROAD PUBLIC HEALTH ASSESSMENT FINAL RELEASE

Absorption How a chemical enters a persons blood after th~ chemical has been swallowed has come into contact with the skin or has been breathed in

Acute Exposure Contact with a chemical that happens once or only for a limited period of time ATSDR defines acute exposures as those that might last up to 14 days

Adverse Health Effect A change in body function or the structures of cells that can lead to disease or health problems

ATSDR The Agency for Toxic Substances and Disease Registry ATSDR is a federal health agency in Atlanta Georgia that deals with hazardous substance and waste site issues ATSDR gives people infonnation about harmful chemicals in their environment and tells people how to protect themselves from coming into contact with those chemicals

Background Level An average or expected amount of a chemical in a specific environment or amounts of chemicals that occur naturally in a specific environment

Cancer A group of diseases that occur when cells in the body become abnonnal and grow or multiply out of control

Cancer Slope Factor An upper bound approximating a 95 confidence limit on the increased cancer risk from a lifetime exposure to an agent This estimate usually expressed in units of proportion (of a population) affected per mglkglday is generally reserved for use in the low-dose region of the dose-response relationship that is for exposures corresponding to risks less than 1 in 100

Carcinogen Any substance shown to cause tumors or cancer

CERCLA Comprehensive Environmental Response Compensation and Liability Act Also known as Superfund

Chronic Exposure A contact with a substance or chemical that happens over a long period of time ATSDR considers exposures of more than one year to be chronic

Completed Exposure Pathway (See Exposure Pathway)

Comparison Value (CVs) Concentrations or the amount of substances in air water food and soil that are unlikely upon exposure to cause adverse health effects Comparison values are used by health assessors to select which substances and environmental media (air water food and soil) need additional evaluation while health concerns or effects are investigated

37


Concern A belief or worry that chemicals in the environment might cause hann to people

Concentration How much or the amount of a substance present in a certain amount of soil water air or food

Dermal Contact A chemical getting onto your skin (See Route of Exposure)

J)ose The amount of a substance to which a person may be exposed usually on a daily basis oose is often explained as amount of substances(s) per body weight per day

DoseResponse The relationship between the amount of exposure (dose) and the change in body function or health that results

Duration The amount of time (days months and years) that a person is exposed to a chemical

Environmental Contaminant A substance (chemical) that gets into a system (person animal or the environment) in amounts higher than that found in Background Level

Environmental Media Usually refers to the air water and soil in which chemicals of interest are found Sometimes refers to the plants and animals that are eaten by humans Environmental Media is the second part of an Exposure Pathway

US Environmental Protection Agency (EPA) The federal agency that develops and enforces environmental laws to protect the environment and the publics health

Exposure Coming into contact with a chemical substance For the three (3) ways people can come into contact with substances- (See Route of Exposure)

Exposure Pathway A description of the way that a chemical moves from its source (where it began) to where and how people can come into contact with (or get exposed to) the chemical

ATSDR defines an exposure pathway as having five (5) parts

1 Source of Contamination 2 Environmental Media and Transport Mechanism 3 Point of Exposure 4 Route of Exposure and 5 Receptor Population

When all 5 parts of an exposure pathway are present it is called a Completed Exposure Pathway Each of these 5 terms is defined in this Glossary

38

F

oLD WILMINGTON ROAD PUBLIC HEALTH ASSESSMENT FINAL RELEASE

Frequency How often a person is exposed to a chemical over time for example every day once a week twice a month

aazardous Waste Substances that have been released or thrown away into the environment and under certain conditions could be harmful to people who come into contact with them A waste may be hazardous by listing (by EPA) or by meeting certain criteria such as corrosivity

Jiealth Effect ATSDR deals only with Adverse Health Effects (See Definition in this Glossary)

Ingestion Swallowing something as in eating or drinking It is a way a chemical can enter your body (See Route of Exposure)

Inhalation Breathing It is a way a chemical can enter your body (See Route of Exposure)

LOAEL Lowest Observed Adverse Effect Level The lowest dose of a chemical in a study or group of studies that has caused harmful health effects in people or animals

MRL Minimal Risk Level An estimate of daily human exposure - by a specified route and length of time - to a dose of chemical that is likely to be without a measurable risk of adverse noncancerous effects An MRL should not be used as a predictor of adverse health effects

NPL The National Priorities List (Which is part of Superlund) A list kept by the US Environmental Protection Agency (EPA) of the most serious uncontrolled or abandoned hazardous waste sites in the country An NPL site needs to be cleaned-up -or is being looked at to see if people can be exposed to chemicals from the site

NOAEL No Observed Adverse Effect Level The highest dose of a chemical in a study or group of studies that did not cause harmful health effects in people or animals

Pegmatite A coarse-grained igneous rock of granitic mineralogy

Plume A volume of air or water containing chemicals which have moved and may continue to move from the source to areas further away A plume can be a column or clouds of smoke from a chimney contaminated underground water or contaminated surface water (such as lakes ponds and streams) A plume that has stabilized (boundaries unchanging with time) is said to be in steady state

Population A group of people living in a certain area or the number of people in a certain area

39

1 a p


Public Health Hazard The category Public Health Assessments used in (PHAs) for sites that have certain physical features or evidence of chronic site-related chemical exposure that could result in adverse health effects middot

Public Health Hazard Criteria PHA categories given to a site that tell whether people could be harmed by conditions present at the site Each are defined in the Glossary The categories

are Urgent Public Health Hazard Public Health Hazard Indeterminate Public Health Hazard No Apparent Public Health Hazard No Public Health Hazard

Reference Dose (Rfl)) An estimate with safety factors (see safety factor) built-in of the daily lifetime exposure of human populations to a possible hazard that is not likely to cause hann to the person

Route of Exposure The way a chemical can get into a persons body There are three (3) exposure routes

breathing (also called inhalation) eating or drinking (also called ingestion) and or getting something on the skin (also called dermal contact)

Sample A small number of people chosen from a larger population (See Population)

Safety Factor Also called Uncertainty Factor When scientists do not have enough information to decide if an exposure will cause hann to people they use saf~ty factors and formulas in place of the information that is not known These factors and formulas can help determine the amount of a chemical that is not likely to cause hann to people

Source (of Contamination) The place where a chemical comes from such as a landfill pond creek incinerator tank or drum Contaminant source is the first part of an Exposure Pathway

Toxic Harmful Any substance or chemical can be toxic at a certain dose (amount) The dose is what determines the potential hann of a chemical and whether it would cause someone to get sick

Tumor Abnormal growth of tissue or cells that have formed a lump or mass
