Abstract
The Heckathorn Superfund Site in Richmond, California, encompasses the property of the former United Heckathorn pesticide packaging plant and the adjacent waterway, Lauritzen Channel. The site was used from 1945 to 1966 by several operators to produce various agricultural chemicals. The site was placed on the National Priorities List of Superfund sites in 1990, which resulted in the removal of pesticide-contaminated soil from the upland portion of the site and dredging the marine portion of the site. Post-remediation marine monitoring and associated studies conducted through 2002 indicate that the contamination in the channel continues to pose a significant risk to biota and human health. This report documents continued marine monitoring and source investigation studies conducted in 2003.

1.0 Introduction
This report is a brief summary of post-remediation monitoring and associated studies conducted at the United Heckathorn Superfund Site in Richmond, California in 2003. These are follow-on studies to earlier investigations described below. Because the text is so brief, all figures and tables follow the text so as not to interrupt the flow of the document.
1.1 Site Background
The Heckathorn Superfund Site in Richmond, California, encompasses the property of the former United Heckathorn pesticide packaging plant and the adjacent waterway, Lauritzen Channel (Figure 1). The site was used from 1945 to 1966 by several operators to produce various agricultural chemicals, including dichlorodiphenyl trichloroethane (DDT), its breakdown products dichlorodiphenyl dichloroethane (DDD) and dichlorodiphenyl dichloroethylene (DDE), dieldrin, and other pesticides. The site was placed on the National Priorities List of Superfund sites in 1990, which resulted in the removal of pesticide-contaminated soil from the upland portion of the site and dredging the marine portion of the site.
Remediation of the channel by dredging, dewatering, and offsite disposal of contaminated sediment took place between July 1996 and March 1997. Sampling during the dredging operation indicated that the significant mass of contamination was removed. However, subsequent sampling, particularly at the 2-year post-remedial sampling of marine water and biota (1998 to 1999), indicated pesticide contamination significantly above the remediation goals in the Record of Decision and suggested that there was a potential recontamination problem in the channel. The post-remediation marine monitoring and associated studies, described in Section 1.2, indicate that the contamination in the channel continues to pose a significant risk to biota and human health.
1.2 Previous Investigations
Post-remedial monitoring data demonstrated that the pesticide DDT(a) was less bioavailable to marine biota 2 to 3 years after remediation than it was in the first 6 to 10 months after remediation (Figure 3) (Antrim and Kohn 2000a, b; Kohn and Kropp 2001a). However, DDT was detected in the tens of parts-per-million (ppm) range in sediment samples collected from Lauritzen Channel in October and November 1998. Sediment DDT concentrations greater than 0.590 ppm were first measured in October 1998 and reported in Anderson et al. (2000). DDT in sediment was confirmed by additional measurements in November 1998 (Antrim and Kohn 2000b), and was additionally verified in the 1999 Sediment Investigation (Kohn and Gilmore 2001). Furthermore, an increase in bioavailability of DDT to mussels in Lauritzen Channel was observed in 2001, the fourth year of post-remediation monitoring (Kohn and Kropp 2001b); however, this increase was not apparent the following year (Kohn and Kropp 2002) (Figure 2).
(a) Throughout this document, “DDT” is generally intended to mean DDT and its breakdown products, collec-
tively. “Total DDT” is used to indicate concentrations that are the sum of detected DDT, DDD, and DDE compounds.

Uncertainty about any trend in DDT bioavailability to mussels through 5 years of monitoring prompted the U.S. Environmental Protection Agency (EPA) to continue the biomonitoring program for another year (2003). The results of the 1999 Sediment Investigation and the apparent increase in DDT availability in 2001 triggered EPA to undertake a Phase I Source Investigation study in 2002 (Kohn and Evans 2002). This study identified several potential sources bearing further investigation: a hotspot of sediment contamination beneath the north end of the Levin Pier, embankment soils with elevated concentrations of DDT, and a previously unidentified outfall pipe discharging into the intertidal zone of northeast Lauritzen Channel. Phase II Source Investigation sampling and analysis was undertaken in 2003 to delineate the sediment hotspot, further characterize the depth of contamination in embankment soils, and to verify the outfall discharge. This report summarizes the results of the sixth year of post-remediation biomonitoring and Phase II of the Source Investigation study. All technical reports for previous investigations are available electronically from www.pnl.gov/main/publications, using “Heckathorn” as the search term.

2.0 Methods
2.1 Year 6 (2003) Monitoring
2.1.1 Sample Collection
Water and mussel samples were collected by EPA Region IX staff in the same manner as all previous years of biomonitoring at the Heckathorn site. EPA’s sample collection summary memo is provided in Appendix A. Triplicate water samples were collected at the four routine monitoring locations, the Seep, and Parr Canal (Figure 3, Table 1). Additional replicates for quality control (QC) were collected from Lauritzen Channel End (303.3) and the Seep, for a total of 20 water samples. Mussel samples were collected at the four routine monitoring locations and four additional locations in Lauritzen Channel. Two of the additional locations are near elevated water or sediment.
2.1.2 Water Sample Analysis
With one exception, triplicate water samples from each of the four routine monitoring locations were analyzed for total DDT (2,4’- and 4,4’- isomers of DDT, DDE, and DDD), dissolved DDT compounds, and total suspended solids (TSS). The exception was Richmond Inner Harbor 303.1, where one of the triplicates was used for QC because the planned QC replicate (from 303.3) was broken during shipping. All water analyses were conducted by Columbia Analytical Services, Kelso, Washington. Upon receipt at the laboratory, each 4-L sample was split as follows: approximately 220 mL was removed for TSS and the remaining volume was split in half for total and dissolved pesticides. The aliquots for total pesticides were assigned suffix –T. The aliquots for dissolved pesticides were assigned suffix –D, transferred to polycarbonate containers, and centrifuged to remove particulate matter. The supernatant was decanted for subsequent analysis of dissolved pesticides.
TSS was analyzed by EPA Method 160.2. The method detection limit (MDL) is typically 1 mg/L TSS, but because the sample volume was limited, the reporting limit for this study was 5 mg/L TSS. The laboratory attempted to achieve lower reporting limits, but values less than 5 mg/L are flagged as estimates (“J”). Organochlorine pesticides were analyzed by EPA Method 8081A; polychlorinated biphenyl (PCB) aroclors were analyzed by EPA Method 8082. The laboratory noted matrix interference in the field samples that prevented reporting to the MDL of 0.05 ng/L to 0.12 ng/L for the target pesticides; reporting limits for field samples ranged from 0.48 ng/L to 0.87 ng/L. In the case of dieldrin, the laboratory MDL was 0.06 ng/L, but the reporting limits for field samples were 0.48 ng/L to 0.50 ng/L.
2.1.3 Tissue Sample Analysis
Eight mussel tissues were analyzed for pesticides and lipid content by Columbia Analytical Services, Kelso, Washington. Chlorinated pesticides were analyzed by EPA Method 8081A; PCB aroclors were analyzed by EPA Method 8082. Lipids were analyzed by the Bligh-Dyer method for consistency and comparison with pre-remediation and other post-remediation data. Lipids were also measured using EPA Method 3450. This method is efficient in that it does not require a separate sample aliquot or extraction: lipids are measured gravimetrically in the same methylene chloride extract that is prepared for pesticide
4
analysis. The two methods are fairly comparable, with typically less than 30% difference in results. In this case, the Seep mussel sample was too small to allow a separate Bligh-Dyer lipid extraction, and the EPA 3450 data allowed an estimate of a Bligh-Dyer-equivalent lipid content (Figure 4).
2.2 Phase II Source Investigation
The Phase II Source Investigation was a follow-on study of potential sources of pesticides to Lauritzen Channel identified in the Phase I Source Investigation. The objectives of the Phase II Source Investigation were to 1) further characterize the depth of contamination in embankment soils, 2) delineate the sediment DDT hot spot beneath the north end of the Levin Pier, and 3) survey Younger Bay Mud (YBM) thickness and DDT concentrations throughout Lauritzen Channel.
2.2.1 Sample Collection
Embankment soil and sediment core samples for the Phase II Source Investigation were collected May 20-22, 2003. Embankment soil samples were collected by Battelle and EPA personnel; both diver-collected cores and vibracores were collected by TEG Oceanographic Services of Santa Cruz, California. Locations of Phase II Source Investigation soil and sediment samples are shown in Figures 5 through 7. Sample collection and preparation information is provided in Tables 2 through 5. Sample collection activities are described below.
2.2.1.1 Embankment Samples
Embankment soils from the northeastern edge of Lauritzen Channel were collected during a low tide when the bank was accessible from land. Sampling locations were selected by EPA to represent areas of documented shoreline activities, such as railroad scale use and removal, or prior excavations and bank stabilization. Embankment soil collection information is provided in Table 2. Most samples were collected near the high tide mark, just below the vertical wall or armoring (see descriptions in Table 2 and photos in Figure 8). A hand auger with a stainless steel bit was used to penetrate the sediment surface and collect a sample from the 0- to 0.2-ft (~2.5 in.) interval. The sampler bit was rinsed thoroughly with seawater before augering deeper in the same location to collect a sample from the 0.5- to 1-ft-depth interval. If the location was on a slope, the auger was inserted perpendicular to the slope to determine the true thickness of a contaminated layer. Soil samples were placed directly into labeled sample jars for pesticide, grain size, and total organic carbon (TOC) analysis; sealed sample jars were stored on ice in coolers until transferred or shipped to the appropriate analytical laboratory.
2.2.1.2 Diver-Collected Cores
Cores were collected by TEG divers at 17 stations selected by EPA to delineate the DDT hotspot identified in the Phase I Source Investigation. The hotspot was located at the north end of the Levin Pier, beneath the pier face at Transect +2.5. EPA first placed four stations along the pier face, about 15 ft and 30 ft north of the hotspot (1-N, 2-N), and about 15 ft and 30 ft south of the hotspot (1-S, 2-S). Three stations were placed approximately 25 ft west of the pier face and between the stations on the first line of samples (1-NW, 1-W, and 1-SW). Station 2-W was located another 25 ft out so that it was about 50 ft west of the hotspot. Four more stations were located under the pier about half way between the pier face
5
and shore embankment (approximately 12 ft east of pier face): 1-NE, 2-NE, 1-SE, and 2-SE. Although these 13 were the only stations planned, diver time and coring supplies were available to collect four additional samples. The last four stations were located even further east, as close to the embankment as possible in the first four gaps between rows of pilings supporting the Levin Pier (whole transect numbers indicate piling rows, half numbers indicate a gap between piling rows): T(+1.5)E, T(+2.5)E, T(+3.5E), and T(+4.5)E.
Diver-collected cores were obtained by pushing by hand a 2-ft section of 2-in. diameter tubing into the sediment to maximum penetration. The diver would cap the top, dig to the bottom, and cap the bottom before removing the tube from the sediment. Capped, labeled cores were transported to shore, where the stratigraphy was described before sediment was transferred to a disposable aluminum pie plate, homogenized, and split into aliquots for pesticide, grain size, and TOC analysis (Table 5; Figure 9).
2.2.1.3 Vibracores
Vibracore samples were collected at 11 stations in Lauritzen Channel on May 22, 2003. Vibracore sampling stations were located in central and southern Lauritzen Channel to expand the hotspot delineation and fill gaps in the data obtained during the 1999 Sediment Investigation (Figure 7). The goal of the vibracore sample collection was to penetrate through the YBM into the Older Bay Mud (OBM) to determine the present-day thickness of overlying YBM and the concentration of pesticides in the YBM.The vibracore sampler was operated by TEG Oceanographic Services; it was deployed from TEG’s 24-ft pontoon barge, which was anchored at each station prior to sampling (Figure 10).
Vibracore sampling information is provided in Table 4. OBM was retained in all cores except H03-12, where hard clay was reached but not penetrated sufficiently to retain. Throughout the sampling day, capped, labeled vibracores were transported to shore for processing and chemistry subsampling. Vibracores were processed by splitting longitudinally using reciprocating shears and gently prying the halves apart (Figure 11). The stratigraphy and sediment characteristics were described, and YBM was removed and homogenized in a disposable aluminum pie plate. Homogenized sediment was split into aliquots for pesticide, grain size, and TOC analysis (Table 5).
2.2.2 Sediment and Soil Sample Analysis
All sediment and soil samples were analyzed for pesticides by the EPA Region IX Laboratory in Richmond, California. Chlorinated pesticides and PCB aroclors were analyzed by EPA Method 8081A. The EPA Region IX Laboratory also analyzed TOC in sediment samples by EPA Method 9060. Grain size analysis by ASTM D422-63 method was performed by Columbia Analytical Services of Kelso, Washington.

3.0 Results
3.1 Year 6 (2003) Monitoring
3.1.1 Water Samples
Results for TSS, dieldrin, and DDT compounds in the total fraction samples are provided in Table 6; results for dieldrin and DDT in the dissolved fraction samples are shown in Table 7. Water samples were also analyzed for PCB aroclors but none were detected. All water analysis results received from the laboratory are provided in Appendix B.
It is difficult to evaluate the water chemistry relative to marine water quality criteria because of the elevated reporting limits for dieldrin and some DDT compounds. Dieldrin reporting limits were usually around 0.5 ng/L, 3 to 4 times the 0.14-ng/L remediation goal. The elevated reporting limit is not an issue where dieldrin was clearly detected, as in samples from Lauritzen Channel End 303.3 and the Seep sample. DDT reporting limits, although elevated (0.48 ng/L to 0.87 ng/L compared with MDLs of 0.05 ng/L to 0.12 ng/L), were usually below the 0.59-ng/L remediation goal. It is still clear that there is a gradient of total DDT that decreases with distance from Lauritzen Channel End (303.3). In 2003, the Lauritzen Channel End water samples showed an order-of-magnitude increase in both total and dissolved DDT concentrations from the previous year of monitoring (Table 8, Figure 12). It should be noted that these water samples provide just a snapshot of water-column DDT concentrations and thus provide no information about the temporal variability or vertical stratification of contaminants in the water column. The differences between sampling events do not necessarily verify trends, nor are individual samples necessarily representative of typical conditions.
3.1.2 Tissue Samples
Shell length of individual mussels and mean mussel tissue weight per mussel at each station were measured for Year 6 monitoring (Table 9). The target DDT pesticides were detected in all Year 6 tissue samples (Table 10). Concentrations in mussels from the four routine monitoring locations ranged from 25 µg/kg and 28 µg/kg wet weight at Santa Fe Channel End (303.4) and Richmond Inner Harbor (303.1), respectively, to 214 µg/kg and 431 µg/kg wet weight at Lauritzen Channel Mouth (303.2) and End (303.3), respectively. These follow a pattern of decreasing DDT concentration with distance from Lauritzen Channel similar to previous years (Figure 13), and Year 6 tissue concentrations were generally similar to Year 5. Of the PCB Aroclors, only Aroclor 1254 was detected in any of the mussel tissues (Table 11). This is consistent with previous years of monitoring.
Mussels collected from the four additional locations in 2003 provide valuable additional information about DDT bioavailability in Lauritzen Channel. Despite very small sample size (6 mussels) at the Seep station, pesticide concentrations in tissues from this station were so elevated that multiple dilutions were required to quantify them. The Seep area clearly represents a much higher exposure to bioavailable DDT. Mussels collected from the ladder at Manson Construction, on the west side of the channel across from 303.3, had similar tissue DDT concentrations to 303.3, suggesting that water in central Lauritzen Channel is fairly well-mixed. Mussels from the 8-in. pipe further north on the east bank of Lauritzen Channel had
8
higher tissue burdens of DDT, about 2.5 times the burden of 303.3 and Manson Ladder mussels. The north end of the channel would not be flushed or mixed as well as the central and south sections, but it is unclear whether the increased exposure is from Seep water pushed upchannel, from erosion of embankment soils, or (most likely) a combination of sources. Similarly, mussels from the pilings supporting the Levin Pier at Transect +2 had tissue burdens about twice those of 303.3 and Manson Ladder mussels, but the contribution of exposure from the Seep water versus the sediment hotspot cannot be easily distinguished.
3.2 Phase II Source Investigation
3.2.1 Soil and Sediment Chemistry
Results for dieldrin, total DDT, grain size, and TOC in embankment soil and channel sediment are summarized in Table 12. Total DDT concentrations by station are provided on the maps in Figures 14 and 15. Results for individual pesticides are provided in Appendix C.
The purpose of analyzing embankment soils was to determine whether DDT occurred only in the surface few inches (“veneer” of contaminant deposited on surface), or if it could be found at depth (residual contaminated upland soil). Results indicated that this depended on the sampling location. At the north end of the channel near the former train scale (Transect -35), the DDT concentration was about 9 times higher in the 0.5- to 1-ft depth interval (14 ppm) than in the surface 0- to 0.3-ft (1.6 ppm) depth interval (Table 12). In the vicinity of the 8-in. pipe protruding from the retaining wall (Transect -29), the DDT concentrations were similar in the surface and deeper intervals (68 ppm and 75 ppm), and slightly higher than the bank soil concentration from nearby Transect -32.5 (53.4 ppm, Phase I Source Investigation). Further south, around the Seep and areas of upland excavation (T-12.5, T-4.5), soil DDT concentrations did exhibit the “veneer” effect, with surface concentrations of 4 ppm to 13 ppm and <0.05 ppm below. However, under the north end of Levin Pier, embankment soils from T+2.25 were substantially more contaminated at depth (135 ppm), whereas the surface concentration of 3.5 ppm was similar to that at T-4.5 (3.8 ppm).
The diver-collected cores and vibracores near the north end of the Levin Pier were collected primarily to delineate the DDT hotspot identified during the Phase I Source Investigation. Although the highest Phase I concentration of 23,000 ppm (T+2.5 at the pier face) was not confirmed in Phase II, the core collected from that same location in 2003 did have the highest core sediment DDT concentration at 1161 ppm. Sediment total DDT concentrations decreased rapidly to the east under the pier, generally by three to four orders of magnitude within 40 ft, where soft sediment concentrations were similar to surface embankment soils (<6 ppm) (Figure 15). Sediment DDT concentrations also decreased relatively rapidly to the north and south, but remained in the 200-ppm range for 50 ft directly west of the Levin Pier (T+2.5), which is directly downslope from the hotspot.
Vibracores collected throughout the southern two thirds of Lauritzen Channel were intended to provide soft sediment distribution and DDT concentration data, primarily to fill spatial gaps in the 1999 data set, such as along the west edge of Lauritzen Channel. Vibracore data confirmed that a smaller hotspot of 156 ppm DDT appears on the west side of the channel across from the Levin Pier (Figure 14). There are no identified sources on the west side of the channel; it is more likely that contaminated
9
sediment is being suspended and redistributed in the channel by a combination of vessel disturbance (propeller wash) and normal tidal currents. Distribution of YBM and associated DDT concentration is discussed further in Section 3.2.2.
3.2.2 YBM and DDT Distribution
All studies conducted to date demonstrate that elevated DDT concentrations in Lauritzen Channel are associated with soft, silty YBM, and that OBM is not contaminated with DDT. The highly compacted, firm OBM acts as a barrier to downward contaminant transport in the sediment column, and thus represents the vertical extent of sediment contamination. Therefore, the distribution of YBM in the channel facilitates the evaluation of contaminant distribution. The thickness of YBM present was measured in all sediment cores collected during the 1999 Sediment Investigation, Phase I Source Investigation, and Phase II Source Investigation. YBM thickness data from all three studies were integrated to estimate the present distribution and volume of YBM in Lauritzen Channel as follows.
First, data from the 1999 study had to be reprojected in ArcView geographic information system (GIS) (v. 3.2, ESRI GIS and Mapping Software) to plot on the same base map and scale as the more recent data. Second, all three data sets were combined in ArcView and then exported to Surfer (v. 8, Golden Software). In Surfer, the kriging method of gridding and contouring the data was used. Kriging is a commonly used algorithm that tends to follow the data patterns more smoothly and creates less of a "bulls-eye" effect around the original data points than do other gridding methods. The grid area was set to include the boundaries of the shoreline file so that sediment thickness could be extrapolated to the shoreline. The resulting contour plot of sediment thickness in 1-cm (0.1-m) intervals is provided in Figure 16. The volume utility in Surfer was used to compute the volume of YBM based on the sediment thickness at each of the data points shown in Figure 16. The resulting total volume of YBM was estimated to be 18,950 cubic yards (cy). Almost half of the volume (9100 cy or 48%) resides in Levin Berths B and C immediately west of the pier. The berths represent only about one third of the area of Lauritzen Channel but they are where sediment is expected to accumulate because it is where the channel is deepest. Approximately 465 cy, or 2.5%, is beneath the Levin Pier.
Prior studies and the Phase II Source Investigation also demonstrated that the total DDT concentrations in nearly all YBM in Lauritzen Channel soft sediment exceeds the remediation goal of 0.59 ppm, and that several hotspots have concentrations five to six orders of magnitude higher. Sediment and embankment soil DDT concentrations for all studies are shown superimposed on the sediment thickness plots for all of Lauritzen Channel (Figure 17) and the hotspot area in east central Lauritzen Channel (Figure 18). The hotspots represent only 0.1% of the surface area, but nearly half of the area (48%) has YBM DDT concentrations between 10 and 100 ppm and another 43% of the area has YBM DDT concentrations between 1 and 10 ppm. Because both east and west sides of the channel are active facilities, vessel traffic is common, although at irregular intervals and with varying degree of activity. The vessels are often tugboats with powerful engines, maneuvering barges or larger vessels in the channel, which can resuspend and mix unconsolidated soft sediment. Resuspended sediment can be transported and deposited elsewhere in the channel or even out of the channel if resuspension occurs during a strong ebb current.

4.0 Discussion
Both water and mussel tissue chemistry results for 2003 show that DDT is still present above the remediation goal, and it is bioavailable and accumulated by resident biota. The Phase I and Phase II Source Investigations served to identify a broken concrete outfall, called the “Seep” in Year 6, below the riprap on the eastern shore about 180 ft north of the Levin Pier (Figure 8). The Phase II Source Investigation also confirmed and delineated the sediment hotspot beneath the north end of Levin Pier. The sediment hotspot, along with the Seep, is probably contributing to high tissue burdens of DDT in mussels collected from Transect +2 pilings. The highest concentrations of DDT were measured in water, sediment, and mussels sampled from the Seep pipe; high DDT in water samples taken approximately a year apart suggests that this Seep represents a persistent, if not continuous, source of DDT to the channel. Soon after draft 2003 data were provided to EPA, EPA took action to have the Seep pipe plugged and sealed when it was exposed at low tide (July 18, 2003). We recommend that the effectiveness of this action to reduce bioavailable DDT be monitored using mussels collected at the eight Year 6 monitoring locations. Once the potentially continuous source of dissolved DDT from the Seep is eliminated, the source of bioavailable DDT should be limited to sediment and embankment soils. The Phase II Source Investigation confirmed prior study results showing that DDT concentrations exceed the remediation goal of 0.59 ppm in nearly all the YBM in Lauritzen Channel. Continued monitoring would allow evaluation of the magnitude of the sediment/soil contribution until it is removed or otherwise remediated.

(a) Mussels were not collected in Parr Canal. As noted in Appendix A, mussels were not plentiful, possibly due to poor substrate or lower salinity.

EPA Field Sampling for Mussels and Seawater
A-1
Field Sampling Summary for Mussels and Seawaterat the United Heckathorn Site in
Richmond, California, conducted 2/25/2003.
Andrew LincoffEPA Region 9 Laboratory
PMD-2March 25, 2003
INTRODUCTION
This sampling event involved the collection of bay mussels and seawater at the United Heckathorn Superfund Site in Richmond, California. Sampling was performed on February 25, 2003 by Andrew Lincoff and Peter Husby of the EPA Region 9 Laboratory, and Carmen White, United Heckathorn RPM. Sampling was performed in accordance with Battelle’s “United Heckathorn Post-Remediation Field Monitoring Plan” (FSP), dated February 5, 1997, and “Sampling and Analysis Plan for the Investigation of Contaminant Source and Contaminant Movement in the Lauritzen Channel, United Heckathorn Site, Richmond, California” (SAP), drafted January 11, 2002.
OBJECTIVE
EPA conducted this field sampling as part of the oversight of a final Remedial Action under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) at the United Heckathorn Site in Richmond, California. The sampling effort involved collecting physical environmental samples to analyze for the presence of hazardous substances.
The United Heckathorn Site was used to formulate pesticides from approximately 1947 to 1966. Soils at the Site and sediments in Richmond Harbor were contaminated with various chlorinated pesticides, primarily DDT, as a result of these pesticide formulation activities. The final remedy contained in EPA's October, 1994 Record of Decision addressed remaining hazardous substances, primarily in the marine environment. The major marine components of the selected remedy included:
- Dredging of all soft bay mud from the Lauritzen Channel and Parr Canal, with offsite disposal of dredged material.
- Marine monitoring to verify the effectiveness of the remedy.
Long-term monitoring is addressed by Battelle’s February 5, 1997 FSP. The purpose of the long-term monitoring is to demonstrate the effectiveness of the remedy. Prior to the remediation,mussels in the Lauritzen Channel contained the highest levels of DDT and dieldrin in the State, and surface water exceeded EPA’s Ambient Water Quality Criteria for DDT by a factor of 50. Lower but
A-2
still elevated levels were found in mussels and surface water in the Santa Fe Channel. It was concluded in EPA’s Remedial Investigation that these elevated levels were the result of continuous flux from contaminated sediments. Approximately 98% of the mass of DDT in sediments in Richmond Harbor was removed by the remedial dredging. The long-term monitoring will demonstrate whether this action has succeeded in reducing the levels of DDT in mussels and surface waters.
Battelle’s FSP included monitoring using both transplanted California mussels and resident Bay mussels. The first round of the long-term sampling occurred in January, 1998. This is the sixth annual round of sampling. The seasonal timing was chosen to match the protocol used by the California State Mussel Watch Program, in order to permit comparison with the State’s results over the past 15 years.In the first two rounds, both transplanted and resident mussels are analyzed to determine any difference. Based on the results of the first two rounds and discussions with California State Mussel Watch Program personnel, only resident mussels were collected in subsequent rounds. Mussels collected on February 25, 2003 were shipped to Battelle for processing prior to analysis by Columbia Analytical.Seawater samples collected on February 25, 2003 were shipped directly to Columbia Analytical.
FIELD NOTES AND OBSERVATIONS
1. 1. Seawater and mussel samples were collected at the routine Mussel Watch station numbers 303.1 to 303.4 used in the previous annual collections and at the Parr Canal station which last year was given the number 303.6. Three gallons of seawater were collected from approximately one foot below the surface at each location. An extra gallon was collected at station 303.3 for lab QC. In addition, three gallons of seawater were collected from a pipe which emerges from the shoreline near station 303.3 called the “seep” (Photo 1). Water can be seen flowing from this pipe when the tide drops. An extra gallon was collected from the “seep” and labeled “blind duplicate.”No time was recorded on the label of the blind duplicate to prevent its identification, but it was collected at the same time as the other “seep” samples.
2. Bay mussels were collected at each of the water stations above except for station 303.6 in the Parr Canal. Mussels are not plentiful in the Parr Canal, possibly due to poor substrate or lower salinity. Bay mussels were also collected at three additional locations: the “seep,” a ladder off the Manson dock, and from piles near an 8” pipe near the northern end of the canal which emerges from Levin’s sheet pile wall (Photo 2). The mussels were all collected near the surface, which at the collection time was approximately at 1 ft above Mean Lower Low Water (MLLW), except for station 303.4 where the mussels were collected near the surface from a floating dock, and the “seep” where the mussels were collected from in and around the mouth of the pipe.
3. The samples were promptly delivered to the Region 9 Lab and the seawater samples were placed in a 4 ºC cold room. The mussels were cleaned of gross debris in the laboratory’s clean filtered seawater, wrapped in ashed foil, placed in zip-loc bags, and stored in a -20 ºC freezer. The
A-3
seawater and mussels were packaged and shipped on March 26, 2003 by Fed Ex. The seawater was shipped chilled to Columbia Analytical and the mussels were shipped frozen to Battelle.
4. GPS coordinates for the sample locations are listed in Table 1. No location was taken at station 303.1 on the day of sampling. The location listed is from the April 10, 2002 sampling report. All locations were differentially corrected with the exception of the “seep.” It was not possible to differentially correct the readings from this location. The cause is unknown. The location listed is the mean of five position recordings.
5. Salinity was measured using a refractometer in seawater from the "seep" and nearby station 303.3.The salinity of the "seep" was 21 parts per thousand (ppt) and the salinity at station 303.3 was 23 ppt.
