Re: Prussian Blue EOC Study, Wyandotte, MichiganTDD# 5-8911-25
Dear Mr. Heaton:
On November 25, 1989 the U.S. Environmental Protection Agency (U.S.EPA) tasked the Technical Assistance Team (TAT) to conduct anextent of contamination (EOC) study at the Prussian Blue site inWyandotte, Michigan. The attached report summarizes the sitehistory, the EOC sampling and analytical results of samplescollected by the TAT.
The analytical results of samples collected by the TAT indicatedlevels of cyanide in both soil and ground water at various areasthroughout the site. Base/neutral extractable compounds were notdetected in these samples, as they were in samples collected by theTAT during the previous site assessment. As requested by the On-Scene Coordinator (OSC), two composite samples were sent forincineration/landfill disposal parameters analysis. Based on theseanalytical results, the waste is not classified as a ResourceConservation and Recovery ACT (RCRA) characteristic waste. Thesamples indicated no evidence of ignitability, corrosivity,reactivity or Toxic Characteristic Leachate Process (TCLP)toxicity.
Based on the visual observations of the blue waste material duringthe EOC study, supplemented by analytical results of the samples,the TAT has estimated the volume of waste and contaminated soils tobe 1360 cubic yards.

1.0 INTRODUCTION
The Prussian Blue (P-B) site consists of several land parcels in aresidential area surrounding in the City ofWyandotte, Wayne County, Michigan (Figure 1). Historical dumpingfrom an unknown source has led to the presence of a blue wastelayer in the surface and subsurface soils containing elevatedlevels of total and free cyanide. Although the full extent of thewaste layer is unknown, the site mainly consists of the parcels at
and two vacant parcels to the east on the northside of the street (Figure 2) . The waste layer has also beenobserved at the parcel of land encompassing on thesouth side of the street. All inclusive, the site occupies an areaof approximately 40,000 square feet. The site is bordered to thenorth by the Ecorse River and further north by the Great LakesSteel Company, and to the east, west, and south by several otherresidences.
2.0 SITE BACKGROUND
Prior to development, the site and surrounding land along thesouthern banks of the Ecorse River was a marshy floodplain. Aerialphotographs, dated 1945, show low-lying marshlands on the northside of North Drive, with houses built on the south side of thestreet. Long-time residents recall that the area encompassing thesite was once used as a fill area, however, no one could confirm anapproximate date of this activity. According to the City ofWyandotte Assessor's Office, the house at was builtin 1955. The blue waste material may have been dumped during thefill operations there prior to the construction of the house at
2.1 Chronology of Events
The present occupant of , called theWayne County Health Department (WCHD) on October 3, 1989 withquestions concerning blue-colored soil he had observed whileexcavating to replace his driveway. WCHD representative HankMaciejewski responded on October 4, 1989, and sampled soil from thedriveway. Analytical data showed elevated levels of cyanide (3300parts per million (ppm) and 6400 ppm in a test run twice on samesample) . The site was then referred to the U.S. EnvironmentalProtection Agency (U.S. EPA) Emergency and Enforcement ResponseBranch by WCHD.
On October 27, 1989, the U.S. EPA tasked the TAT to conduct a siteassessment of the P-B site. TAT members Dan Capone and CherylKreindler conducted the site assessment on October 30, 1989 andobserved stressed vegetation and visibly stained soil to the eastof the house at Blue stained soil was alsoobserved in the soil where the driveway was being repaired.Boreholes dug by the TAT members revealed that the blue waste layer

varied in position from the surface to a depth of two feetthroughout the area around and was also variablein thickness. Analytical results of samples collected during thesite assessment showed elevated levels of cyanide in soils rangingfrom 31.6 to 2120 ppm. (See TAT Site Assessment Report dated July11, 1990 - TDD# 5-8910-48).
On November 25, 1989, the U.S. EPA tasked the TAT to conduct anextent of contamination (EOC) study to determine the boundaries andvolume of the blue waste material and associated contaminated soilsat the P-B site.
3.0 SAMPLK PLAN OBJECTIVES AND SAMPLING METHODS
The objective of the EOC sampling plan was to define the verticaland lateral extent of the waste material and contaminated soilwithin the North Drive neighborhood, so that a more accurateestimate of the volume of waste could be made. The TAT developedan EOC Sample Plan which called for installing boreholes on a 80foot by 100 foot grid on the north side of North Drive and on a 80foot by 70 foot grid on the south side of North Drive. A copy ofthe EOC Sample Plan developed by the TAT is found in Attachment A.
During the week of April 25, 1990, TAT members Dan Dyer, KatieMooney, Bruce Van Otteren, Jeff Albano, and Andrea Urda-Thompsonconducted the extent of contamination study at the P-B site.Initially, boreholes were dug in the main area of knowncontamination at eleven stations located in the parcels at and
and the two vacant parcels to the east (Figure 3).Subsequent boreholes were dug at stations east and west of thisinitial area. If blue waste was observed, boreholes were continuedconsecutively outward until an uncontaminated boring was observed.The subsequent borehole was located half the distance between theprevious contaminated location and the uncontaminated location.This method was continued until the limits of contamination werefound. On the south side of North Drive, in parcels around
boreholes were dug at locations chosen by OSC BobBowlus. At each location boreholes were dug with either a posthole digger or a trier (Figure 4).
Boreholes at each station, were dug down to the water table and thesoil was visually observed to document the presence or absence ofthe blue waste layer. If blue waste was encountered, theapproximate depth and thickness of the layer was recorded. Soilsamples were collected in the boreholes where a distinct layer wasobserved. These samples were collected below the waste layer todetermine if leaching of contaminants from the waste layer wasoccurring.
In many of the boreholes the blue waste layer extended into theground water therefore, soil samples were not collected below thewaste layer. Ground water samples were collected in two boreholes

where the waste layer extended below the water table to determineif contaminants had entered the ground water. The ground water inthese boreholes was dark blue in color. TAT member Urda-Thompsonanalyzed these samples on site utilizing a free cyanide spot testkit. Results of the spot test indicated that no free cyanide wasdetected in any of the samples.
A total of five soil samples (S22 through S26) and two ground watersamples (S19 and S20) were collected by the TAT during the EOCsampling (Figure 5). All samples were analyzed for total cyanide,pH, base/neutral extractable compounds, and total metals. Sampleswere sent to Analytic and Biological Laboratories, Inc., FarmingtonHills, Michigan for analysis on April 30, 1990, under TATAnalytical Service TDD # 5-9004-L18. Two composite samples,comprised of blue waste material from four stations, were collectedby the TAT and analyzed for incineration and landfill disposalparameters. Arrangements for analysis of these samples were madeby the Emergency Response Cleanup Service (ERGS) contractors, PEIAssociates. These samples were also analyzed at Analytical andBiological Laboratories, Inc.
4.0 ANALYTICAL RESULTS
The analytical results of the soil and ground water samplescollected by the TAT are summarized in Table 1. Cyanide levels inthe ground water samples S19 and S20 were 229.5 ppm and 53.5 ppmrespectively. Cyanide levels in the soil samples collected frombelow the blue waste layer ranged from 4.5 ppm in sample S22 to 408ppm in sample S25. These results serve to affirm the TAT concernthat cyanide has migrated from the blue waste material into boththe soils beneath the waste layer and into the ground water. Soilsample S26 was collected from a whitish soil layer observed in thesame borehole as soil sample S25. The material is believed to belimestone and the analytical results of the pH (12.15) wouldcertainly support this belief. The pH of the two ground watersamples were on the acidic side at 3.8 and 2.2. Base/neutralextractable compounds were not detected in either the water or thesoil sample. Concentrations of all metals were within the range oftypical concentrations found in natural soils (Table 1).
Analytical results of the blue waste composite samples forincineration/landfill disposal parameters are summarized in Table2. The waste is not classified as a Resource Conservation andRecovery Act (RCRA) characteristic waste based on analysis because:
o organic compounds, metal, and pesticide concentrationswere either not detected or below the maximumconcentration levels as regulated under RCRA, using theToxicity Characteristic Leachate Process analyticalprocedure;
o pH for both samples were 4;

o flash points were >200 °F for both samples; and
o neither sample exhibited the characteristic ofreactivity.
Both samples contained high levels of cyanide at 1,764 parts permillion (ppm) and 4,127 ppm. No polychlorinated biphenyl (PCB) orpesticides were detected in either sample.
5.0 VOLUME OF CONTAMINATED SOIL
In accordance with the sampling plan guidelines, the volume of soilto be excavated has been calculated based upon:
o the presence, location, and lateral extent of the bluewaste material and contaminated soil and;
o the depth of the blue waste material and contaminatedsoil.
The total volume of waste and contaminated soil is estimated atapproximately 1,356 cubic yards. The location and the volumeestimates of the affected areas are displayed in Figure 6 and areoutlined as follows:
o Front yard, - 80'x30'x3' = 267 cu. yds.o east driveway and vacant lot -
100'x20'x2 = 148 cu. yds.o Backyard, - 80'x30'x2.5' = 222 cu. yds.o Brush pile area, - 40'x30'2' = 88 cu.
yds.o West side of - 30'xlO'xl' = 11 cu. yds.o Garden area, - 100'x40'x3' = 444 cu. yds.o Front yard, - 30'x40'x2' = 88 cu.yds.o Front yard, - 30'x40'x2' = 88 cu. yds.
Where the waste layer extended into the ground water a thicknessestimation of three feet was used.
Although, the ground water has been shown to contain elevatedlevels of cyanide, no estimation as to the extent of the groundwater contamination can be given based on the limited amount ofinformation. The suspected direction of ground water flow istoward the Ecorse River to the north. The potential exists for thecontaminated ground water to be discharging into the Ecorse Riverand adversely affecting the aquatic life.

1.0 INTRODUCTION
The Prussian Blue (P-B) site consists of several land parcels inthe residential area surrounding in the city ofWyandotte, Wayne County, Michigan (Figure 1) . A blue industrialwaste, believed to be Prussian Blue, containing elevated levels ofcyanide and base/neutral compounds, contaminates the soilthroughout these parcels. This blue waste layer contaminates thelot at the vacant lot to the east and has alsobeen discovered across the street at The siteencompasses at least a 40,000 square foot area, bordered by theEcorse Creek to the north and residential properties on all othersides (Figure 2). Prior to development, the site and surroundingland along the southern banks of the Ecorse Creek was a marshyfloodplain. Aerial photographs, dated 1945, show low-lyingmarshlands on the north side of North Drive, with several housesbuilt on the south, east and west sides of the site. The sourceand extent of the contamination throughout the neighborhood is notpresently known.
The present property owner at ,contacted the Wayne County Health Department (WCHD) on October 3,1989 with questions concerning blue-colored soil he had found whileexcavating and replacing his driveway. WCHD representative, Mr.Hank Maciejewski, responded on October 4, 1989, and sampled soilfrom the driveway. Analytical results showed elevated levels ofcyanide (3300 parts per million [ppm] and 6400 ppm). The site wasthen referred to the U. S. Environmental Protection Agency (U.S.EPA) Emergency and Enforcement Response Branch by WCHD.
The Technical Assistance Team (TAT) subsequently conducted a siteassessment and sampling on October 30, 1989. During this siteassessment, the TAT observed blue stained gravel in the excavateddriveway of blue spots throughout the grass in theside, front and backyards, and throughout the vacant lot to theeast. Subsequent boreholes dug by the TAT revealed the blue wastelayer at varying depths down to two feet below the surface.Analytical results of samples collected in the area showed elevatedlevels of total cyanide ranging from 31.6 ppm to 2,120 ppm andvarying concentrations of several base/neutral compounds.
On November 25, 1989 the U.S. EPA tasked the TAT to prepare anextent-of-contamination (EOC) sampling plan to determine theboundaries and volume of the contaminated waste layer.
2.0 SAMPLE PLAN OBJECTIVE
The objective of this EOC sampling plan is to define the verticaland lateral extent of the contaminated waste within the North Driveneighborhood. EOC results will be used to estimate the boundariesof the contamination. This information will be used to estimatethe volume of contaminated soil and to determine the scope of apotential removal project for the P-B site.

3.0 SAMPLING METHODS
In order to accomplish the sampling objectives, soil borings willbe dug at the stations outlined in Figure 3. Due to the potentialfor structures, such as driveways and garages, to be located on thetheoretical sampling stations, it may be necessary to adjust theborehole locations once on site. Boreholes will be dug at eachstation down to the water table and the soil will be visuallyobserved to document the presence or absence of the blue wastelayer. If the blue waste layer is encountered, the approximatedepth and thickness of the layer will be recorded. Samples of thesoil beneath the waste layer will be collected for laboratoryanalysis.
Initially boreholes will be dug at the nine stations locatedbetween parcels 22 through 26, the two stations located betweenparcels 91 and 92, and at the northernmost stations between parcels93 and 94 and parcels 89 and 90 (Figure 3). Subsequent boreholeswill be dug at stations east and west of this initial area. If theblue waste is observed, boreholes will continue consecutivelyoutward until an uncontaminated boring is observed. A compositesample will be collected from this borehole for laboratoryanalysis, and the subsequent borehole will be located half thedistance between the previous contaminated location and theuncontaminated location. This method will continue in alldirections until the limits of contamination are found. Inaddition, several samples of blue waste will be collected forlaboratory analysis to better define contaminant concentrations.
Boreholes will be dug at each station with a power auger or a post-hole digger and samples will be collected using a hand-heldsampling auger. All augers and sampling equipment will be properlydecontaminated prior to sampling at each station.
4.0 SAMPLE ANALYSIS
Samples collected for laboratory analysis will be analyzed fortotal and free cyanide, base/neutral compounds, and pH. Inaddition, composite samples of the blue waste will be collected andsubmitted to disposal facilities for acceptance authorization.Samples will be properly collected, labelled, packaged, and shippedor delivered to the chosen laboratory following Weston's samplingprotocol.
5.0 QUALITY ASSURANCE/QUALITY CONTROL (PA/PC)
In order to ensure that quality analytical data is obtained,standard QA/QC methods will be followed by field samplingpersonnel. At a minimum the following protocol will beincorporated into the P-B site sampling scheme:
o Background soil samples will be collected in areas awayfrom potential contamination.

o Field duplicate samples will be collected forapproximately 10% of the total samples collected. Thiswill be accomplished by collecting two samples from thesame station and depth. Each sample will be given aunique sample number so that the laboratory is not awareof sample duplicates.
In addition, analytical results of all samples received from thelaboratory will be reviewed by the Region V TAT Sample Managementpersonnel to assure that the laboratory followed the appropriateQA/QC procedures and did not experience problems which would affectthe quality of the data.
