1 ENVIRONMENTAL CONSULTING & MANAGEMENT ROUX ASSOCIATES INC 209 SHAFTER STREET Islandia, New York TEL FAX July 13, 2009 Mr. Steve Zahn New York State Department of Environmental Conservation Hunters Point Plaza st Street Long Island City, New York Re: White Island Sampling Results White Island Brooklyn, New York Dear Mr. Zahn: On behalf of the City of New York Department of Parks and Recreation (NYCDPR), Roux Associates, Inc. (Roux Associates) has completed sediment and water quality sampling activities on White Island (Site; Figure 1). The objective of the sampling plan was to confirm observations of impacted soil/sediment and identify potential leachate migration from the island to the surrounding surface water bodies (i.e., Mill Creek and Gerritsen Creek). The following sections summarize the scope of work, results, and conclusions from the sampling activities. Scope of Work Recently, local community groups have expressed concern over potential environmental hazards from the island, specifically discolored soil and the presence of leachate have been observed in various locations surrounding and potentially emanating from the island. The following scope of work was developed to further investigate these concerns and evaluate potential environmental impacts from the island. Task 1: Soil/Sediment Sample Collection; and Task 2: Water/Leachate Sample Collection. Previous observations of discolored soil and leachate have coincided with low tide. Therefore, for consistency, Roux Associates performed all soil/sediment and water quality sampling activities during low tide. The scope of work for each task is further described below. Task 1: Soil/Sediment Sample Collection Soil/sediment samples were collected from nine locations across the island which coincided with the areas of concern identified by the local community (Figure 1). Two of the nine locations coincided with the previous soil investigations competed by EEA and ABB (1995). The surface soil/sediment samples were collected using a hand auger. The hand auger was advanced to a depth of 24 inches below the soil/sediment surface. Soils/sediments were MKW Y.108/LR

2 Mr. Steve Zahn July 13, 2009 Page 2 visibly inspected for changes in lithologic characteristics and potential impacts (i.e., color, texture, odor, staining, etc.) and screened for organic vapors in the field using a photoionization detector (PID). Soils/sediments were described using the Munsell Soil Color Charts and according to the Unified Soil Classifications (USCS) criteria. Field observations were recorded in a dedicated field log. A composite sample was prepared from cuttings representing the 0 to 12-inch depth increment. Soil/sediment samples were submitted to Hampton-Clarke/Veritech (HC-V), a New York Sate approved laboratory, for analysis of the Target Compound List (TCL) for Volatile Organic Compounds (VOCs; USEPA Method 8260), Semivolatile Organic Compounds (SVOCs; USEPA Method 8270), PCBs and pesticides (USEPA Methods 8082 and 8081, respectively), and the Target Analyte List (TAL) for metals (USEPA Method 6010). One randomly selected duplicate soil/sediment sample was also collected and submitted for analysis. All sampling equipment was decontaminated in accordance with Roux Associates Standard Operating Procedures (SOPs) following the collection of each sample. Task 2: Water/Leachate Sample Collection Water quality samples were collected from seven sample locations to quantify the presence of leachate (Figure 1). Sample locations coincided with the above mentioned soil/sediment sample locations as well as previous leachate observations noted by the local community. Water quality samples were directly collected from observed potential leachate locations by hand augering or digging a test pit (approximately 6 to 12 inches deep and 8 to 12 inches wide) and sampling the surface water within the pit. In areas where no indicators of leachate were observed, water quality samples were collected from tidal water adjacent to the soil/sediment sample location (WQ-4). In situ measurements of ph, specific conductance, turbidity, dissolved oxygen, temperature, salinity, total dissolved solids and oxidation-reduction potential were obtained and recorded in a dedicated field log at the time each water quality sample was collected. Measurements were obtained with a Horiba U-22 water quality meter that was calibrated to laboratory standards prior to use. Water quality samples were submitted to HC-V for analysis of the TCL for VOCs (USEPA Method 8260), SVOCs (USEPA Method 8270), PCBs and pesticides (USEPA Methods 8082 and 8081, respectively), and the TAL for metals (USEPA Method 6010). As requested by the local community, three water quality samples were analyzed for dioxins (USEPA Method 625). All sampling equipment was decontaminated in accordance with Roux Associates SOPs following the collection of each sample. Quality Assurance and Quality Control (QA/QC) samples consisting of one random duplicate groundwater sample, one matrix spike, one matrix spike duplicate and one field blank were collected. A trip blank provided by the HC-V was also submitted for analysis with the VOC samples for quality control; TCL for VOCs (USEPA Method 8260 was analyzed). Results The results of the soil/sediment and water quality sampling are presented in the following sections. In an attempt to collect samples from unimpacted areas around the island, soil/sediment (SS-4) and water quality (WQ-4) samples were collected from locations that did not exhibit visible signs of impacts or leachate (Figure 1). Soil profiling observations are summarized in Table 1. The results of the soil/sediment analytical testing are summarized in ROUX ASSOCIATES, INC. MKW Y.108/LR

3 Mr. Steve Zahn July 13, 2009 Page 3 Tables 2 through 6. Water quality field parameters are summarized in Table 7. The results of the water quality analytical testing are summarized in Tables 8 through 12. Photos of the sampling locations are provided in Attachment 1. Further details regarding the sampling results are summarized below. Soil/Sediment Results Locations SS-1 through SS-7 are located along the shoreline of the island whereas locations SS-8 and SS-9 are located near the center of the island. White Island soils were primarily comprised of a fine to medium sand; a clay layer was encountered at locations SS-1, SS-2, and SS-5. Locations SS-1 and SS-2 are located along the northwestern shoreline and location SS-5 is located along the southeastern shoreline. Sample location SS-4 was the only location where no signs of potential leaching were observed such as orange stained soils, it was located along the southern tip of White Island (Figure 1). In general the color of the soils encountered ranged from dark gray (2.5Y /1) to grayish brown (10YR 5/2). As summarized in Table 1, discolored surficial soils/sediment (typically had an orange hue) were observed at locations SS-1, SS-2, SS-3, SS-5, SS-6 and SS-7. Fill was not encountered at locations SS-1 through SS-7; however, it was encountered at locations SS-8 and SS-9. The soil matrix at SS-8 was comprised of sand, mottles were observed within the top 15 inches of soil, fill was encountered at approximately 15 inches below land surface (bls), where gravel, glass and brick were observed. The soil matrix at location SS-9 was comprised of a sandy loam until refusal was encountered at approximately 12 inches bls. Several attempts were made, within close proximity to SS-9 with the hand auger to advance past 12 inches bls. Soil/sediment sampling results were compared to the New York State Department of Environmental Conservation (NYSDEC) 6 NYCRR Part 375 Protection of Ecological Resources criteria and the NYSDEC guidance for marine sediments (Technical Guidance for Screening Contaminated Sediments; NYSDEC, 1999) Low (ERL) and Median (ERM) and Life acute and chronic criteria (as applicable). VOCs VOC concentrations were not detected above the laboratory limit of quantitation at soil/sediment locations SS-3, SS-4 and SS-6. The following VOCs were detected in the remaining soil/sediment samples: 1,2,4-trimethylbenzene m+p-xylene acetone methylene chloride chlorobenzene sec-butybenzene freon 113 tert-butybenzene isopropylbenzene total xylenes VOC concentrations detected in the soil/sediment samples did not exceed either the Part 375 ecological criteria or the benthic aquatic life criteria for chronic toxicity and acute toxicity. ERL and ERM criteria do not exist for VOCs. ROUX ASSOCIATES, INC. MKW Y.108/LR

4 Mr. Steve Zahn July 13, 2009 Page 4 SVOCs SVOC concentrations were not detected above the laboratory limit of quantitation at soil/sediment locations SS-1, SS-4, SS-6 and SS-7. The following SVOCs were detected in the remaining soil/sediment sample locations: benzo(b)fluoranthene di-n-butyl phthalate bis(2-ethylhexyl) phthalate fluoranthene chrysene pyrene SVOC concentrations detected in the soil/sediment samples did not exceed the Part 375 ecological criteria, the ERL criteria or the benthic aquatic life criteria for chronic toxicity and acute toxicity. Metals Various metals were detected in all soil/sediment samples. However, only two locations (SS-5 and SS-9) contained concentrations in exceedance of criteria. Sample location SS-5 contained mercury (0.24 mg/kg) in exceedance of both the Part 375 ecological criteria (0.18 mg/kg) and the ERL (0.15 mg/kg) criteria, but was below the ERM (0.71 mg/kg) criteria. Sample location SS-9 contained lead (170 mg/kg) in exceedance of both the Part 375 (63 mg/kg) and the ERL (46.7 mg/kg) criteria, but was below the ERM (218 mg/kg) criteria. PCBs Aroclor-1260 (SS-9; 110 µg/kg) was the only PCB compound detected above the laboratory limit of quantitation. The detection was above the ERL criteria for total PCBs (22.7 µg/kg), however was below the Part 375 ecological criteria (1,000 µg/kg), the ERM criteria (180 µg/kg), and the benthic aquatic life criteria for chronic toxicity (414 µg/kg) and acute toxicity (138,038 µg/kg). Please note, Part 375 and the Technical Guidance for Screening Contaminated Sediments only have criteria for total PCBs, and not the individual Aroclor compounds. Pesticides Pesticides were detected at three sampling locations: SS-1, the duplicate sample collected for SS-2, and SS-9. Chlordane was detected in the soil/sediment sample collected at SS-1 (44 µg/kg), however Part 375 and the Technical Guidance for Screening Contaminated Sediments do not have criteria for chlordane. 4,4'-DDD and 4,4'-DDE were detected in the duplicate soil/sediment sample collected at SS ,4'-DDD (12 µg/kg) was detected in exceedance of the Part 375 ecological criteria (3.3 µg/kg). Note: the Technical Guidance for Screening Contaminated Sediments does not have criteria for 4,4'-DDD. ROUX ASSOCIATES, INC. MKW Y.108/LR

5 Mr. Steve Zahn July 13, 2009 Page 5-4,4'-DDE (18 µg/kg) was detected in exceedance of the Part 375 ecological criteria (3.3 µg/kg) and ERL criteria (2.2 µg/kg), but was less than ERM criteria (27 µg/kg). 4,4'-DDD, 4,4'-DDT, chlordane and dieldrin were detected in the soil/sediment sample collected at SS ,4'-DDD (5.2 µg/kg) was detected in exceedance of the Part 375 ecological criteria (3.3 µg/kg). Note: the Technical Guidance for Screening Contaminated Sediments does not have criteria for 4,4'-DDD. - 4,4'-DDT (3.72 µg/kg) was detected in exceedance of the Part 375 ecological criteria (3.3 µg/kg) and ERL criteria (1.58 µg/kg), but was less than ERM criteria (46.1 µg/kg), and the benthic aquatic life criteria for chronic toxicity (10 µg/kg) and acute toxicity (1300 µg/kg). - Chlordane (42µg/kg) was detected at SS-9; however Part 375 and the Technical Guidance for Screening Contaminated Sediments do not have criteria for chlordane. - Dieldrin (5 µg/kg) was detected, but did not exceed the Part 375 ecological criteria (6 µg/kg) or the benthic aquatic life criteria for chronic toxicity (170 µg/kg). Water Quality Results Field insitu parameters were analyzed with a Horiba U-22 water quality meter at each of the water quality sampling locations. The results from the analysis are summarized in Table 7. In general, the surface water was very turbid. WQ-4, the location with no observed leachate impacts, exhibited the highest ph, conductivity, salinity and total dissolved solids. WQ-4 was located at the confluence of Mill Creek and Gerritsen Creek, likely contributing to the higher conductivity, salinity, and total dissolved solids measurements. Field parameters measured at remaining locations exhibited similar results. Water quality sampling results were compared to the NYSDEC TOGS Ambient Water Quality Standards and Guidance Values (AWQSGVs) for chronic (fish propagation) and acute (fish survival) effects in saline waters. NYSDEC AWQSGVs were combined with the Life criteria (Technical Guidance for Screening Contaminated Sediments; NYSDEC, 1999) for data comparison; in instances where there were two values for a parameter the lower of the two values was used for evaluation. Water quality sampling and parameters results are summarized in the following sections. VOCs VOC concentrations were not detected above the laboratory limit of quantitation in water quality samples collected from WQ-4 and WQ-5. Benzene was detected at sampling location WQ-7 (1.9 µg/l), however it did not exceed water quality criteria. Chlorobenzene was detected at sampling location WQ-6 (4.2 µg/l), however did not exceed water quality criteria. WQ-1 (39 µg/l), WQ-2 (12 µg/l), WQ-3 (22 µg/l) and WQ-7 (14 µg/l) contained ROUX ASSOCIATES, INC. MKW Y.108/LR

6 Mr. Steve Zahn July 13, 2009 Page 6 chlorobenzene concentrations in exceedance of chronic water quality criteria (5 µg/l), but were below acute water quality criteria (50 µg/l). SVOCs SVOC concentrations were not detected above the laboratory limit of quantitation at water quality sampling locations WQ-2 through WQ-6. 2-Methylnapthalene (3.2 µg/l) was detected at WQ-1; however it did not exceed water quality criteria. Acenaphthene (2.4 µg/l) and di-n-butyl phthalate (3.2 µg/l) were detected at WQ-7; however concentrations did not exceed water quality criteria. Dioxin Screen A dioxin screen was analyzed at three sampling locations: WQ-1, WQ-4 and WQ-6. Dioxins were not detected at any of these locations. Metals Metals were detected in water samples collected from all sample locations. While mercury was detected in soil/sediment samples above ERL criteria, mercury was not detected in water quality samples. Please note, NYSDEC AWQSGVs chronic and acute criteria are only applied to metals in the dissolved form. As water quality samples were only analyzed for total metals as a screening tool, analytical results of the total metal content cannot be evaluated against criteria. PCBs PCBs were not detected in any of the water quality samples collected. Pesticides The following pesticides were detected in water quality samples collected from WQ-5: 4,4'-DDD (0.045 µg/l), 4,4'-DDE (0.015 µg/l) and 4,4'-DDT (0.081 µg/l). 4,4'-DDT exceeded chronic criteria (0.001 µg/l), but did not exceed acute criteria (0.13 µg/l). Please note, water quality criteria are not available for 4,4'-DDD and 4,4'-DDE. Conclusions Soil/sediment sampling results for VOCs and SVOCs did not exceed evaluation criteria. Mercury concentrations in soil/sediment samples slightly exceeded the lowest ecological criteria but were below maximum ecological criteria, therefore indicating minor impacts. Lead and PCBs were detected at SS-9, a sample location on the surface of the island, approximately 300 feet away from the shoreline. As part of the grassland mitigation project, this area of the island will be covered with approximately two feet of sand and will therefore not present a risk to the surrounding communities. Water quality sampling results for SVOCs and PCBs did not exceed water quality criteria. Dioxins were not detected in the water quality samples. The VOC chlorobenzene was detected in exceedance of the chronic water quality criteria, but did not exceed the acute water quality criteria. The pesticide 4,4'-DDT was detected in exceedance of the chronic water quality criteria, but did not exceed the acute water quality criteria. Metals were detected in water samples collected from all sample locations. However, chronic and acute criteria are only applied to metals in the dissolved form. As noted above, ROUX ASSOCIATES, INC. MKW Y.108/LR

7 Mr. Steve Zahn July 13, 2009 Page 7 the water quality samples were very turbid, which likely contributed to the elevated copper, lead, nickel and zinc concentrations in the water quality samples. Copper and nickel are rated as low-mobility metals in neutral soils (McBride, 1994). Most soils absorb copper and nickel strongly; thereby reducing the likelihood these metals were present in the dissolved form. Similarly, lead is the least mobile heavy metals in soils (McBride, 1994), and therefore was not likely present in the dissolved form. Zinc is more soluble and mobile than copper, nickel and lead; however, soil/sediment zinc concentrations were relatively low in areas of potential leachate. Copper, lead, nickel and zinc did not exceed soil/sediment criteria on the perimeter of the island, therefore it is unlikely leachate containing these compounds would be present. Based upon the level of turbidity and the chemical behavior of the detected metals, and the lack of soil/sediment exceedances around the island perimeter, the concentrations of copper, nickel, lead and zinc are likely associated with suspended solids and are not likely present in the dissolved form, and therefore do not pose a risk to the surrounding communities. The results of the soil/sediment and water quality sampling demonstrate only minor impacts from the island on the adjacent surface water bodies. As part of the grassland mitigation project, areas of severely degraded shoreline will be repaired with a variety of slope stabilizing engineering solutions. Low permeable soils will be installed in combination with the slope stabilizing solutions to contain underlying waste and minimize leachate migration into the adjacent surface water bodies.
