Summary of Work Performed On May 06,2014 BEI was at the above mentioned site to perform a sub-surface investigation which included a series of borings conducted in order to analyze soil and groundwater conditions.The borings were conducted in areas where former underground storage tanks might have been located along with former pump islands and other suspect areas of concern.The placement of each boring was strictly based upon visual field evidence gathered just prior to the commencement of the work. Samples were also collected from the area of the suspected septic pool.drain pool and a storm drain at the rear of the building. Three(3)soil(B-1-3)samples were collected in areas where field evidence indicated the possibility of former tanks and/or pump islands.Boring B-1 was collected in the area ofthe formerpump island, which was indicated by way of markings on the asphalt.Soil at the B-1 location was screened with a PID meter to a depth of fifteen(15)below the grade surface.No significant petroleum odors or PID readings were observed while logging soil conditions.Boring 13-2 was conducted in the area believed to be the former underground storage tank(UST)field.This information was provided by the property owner during the investigation.Soil at this location was screened to a depth of 35'below Former Service Station May 2014 Summary of Findings Southold,NY grade surface(bgs).No petroleum odors or PID readings were recorded while logging soil from the B-2 location. During the field investigation a third suspect UST location was observed at the northwest side of the building. Boring B-3 was conducted at this location and soil was screened to a depth of 35' bgs. Again,no petroleum related odors or PID readings were noticed during soil classification activities.Each soil sample collected was analyzed by EPA method 8260 for Volatile Organic Compounds(VOCs)and 8270BN for Serpi-Volatile Organic Compounds(SVOCs). Two(2)groundwater samples(GW-2 and GW-3)were collected from each of the suspect former UST locations. GW-2 was collected at the B-2 location and GW-3 from the B-3 location_ Groundwater was collected at each sample location from 35-37'bgs. Visual observation of the groundwater from both samples appeared to be free of any petroleum related odor or visual staining. Each groundwater sample collected was analyzed by EPA method 8260 for Volatile Organic Compounds(VOCs)and 827OBN for Semi-Volatile Organic Compounds(SVOCs). Additional potentially impacted sub surfaeestructures included:adrain pool connected toan interior floor drain,the suspected septic pool area and a storm drainbehind the building.Each of the samples collected from these areas were analyzed by Suffolk County Department of Health (SCDOH) parameters VOCs and SVOCs. It should also be noted that two(2)additional storm drains were located on the property but,possessed solid bottoms. I - Summary of Findings Lab results for soil sample 134(suspect pump island). collected at a depth of 10-125, did not indicate any constituents detected above the part 375 soil clean-up objectives.No constituents were detected in the B-1 sample.8-2(suspect UST area)was collected at the water table interface from a depth of 32.5-35'.Lab results indicated non-detect readings for all constituents.B-3(suspect UST area)was also collected at the water table interface from 32.5-35'bgs.Lab results for B-3 indicated non-detect readings for all constituents. Groundwater samples GW-2 and GW-3 were collected from boring locations B-2 and B-3 respectively_A11 lab results were compared to the New York State groundwater standards outlined in the Technical and Operational Guidance Series(TOGS)document.Only two minor detections (<1.5 ppb)were observed in each of the groundwater samples collected.No other constituents were detected. Lab results for the drain pool sample(connected to bay floor drain)did indicate some very minor S VOC concentrations.The highest detection was Bis(2-ethylhexyl)phthalate at 320 ppb which is not regulated by the SCDOH.No other constituents were detected above the SCDOH action levels. A boring was conducted in the area of the suspected septic pool and a representative sample was collected from 10-12.5'bgs.No constituents were detected above the SCDOH action levels. A composite sample was collected from a storm drain located at the rear of the building.No VOCs were detected in this sample but,some significant SVOCs were detected above the SCDOH action Former Service Station May 2014 Summary of Findings Southold,NY levels.Benzo(a)anthracene was detected at 10,000 ppb which is above the SCDOH action level of 2.000 ppb.Benzo(b)fluoranthene was detected at 13,000 ppb and Benzo(k)fyuoranthene was detected at 11,000 ppb both above there respective SCDOH action level of 3,400 ppb.Chrysene was also I detected at 15,000 ppb which is above the SCDOH action level of?.000 ppb.The rear storm drain detections are highlighted within the lab data table attached.Please refer to Figure-1 for the location ofall samples collected.A boring log is also attached as Figure 2.Lab data and tabulated lab results are also attached to this report. P Conclusions and Recommendations Lab results for the soil and groundwater samples collected did not indicate the presence any environmental concerns. It is recommended that the rear storm drain be cleaned out in order to comply with the SCDOH clean-up objectives.Endpoint samples should be collected subsequent to the clean-out in ordertoconfirm cmnpliancewiththeregulatoryclean-upobjectives.Samples should be analyzed by SCDOH parameters which includes analysis of VOCs. SVOCs and metals.The SCDOH should also be contacted in order to matte arrangements for oversight of the clean-out and endpoint sampling activities. ti • Sincerely, Beminger Environmeu&4 Inc- Justin Halpin Waiter Berninger Project Manager President/Env.Consultant enc.
