and east, we anticipate that at a minimum, sampling primarily groundwater at 2 to 3 locations on neighboring properties will be necessary to determine magnitude and the extent of the UST release. Soil and groundwater samples should be analyzed for the following laboratory analyses: EPA Method 8260b-VOCs,TPH as Gasoline, 7 fuel additives and lead scavengers EPA Method 8270 - Semi Volatile Organic Compounds EPA Method 8015M-TPH as Diesel and Motor Oil EPA Method 6010 - LUFT 5 Metals (Cadmium, Chromium,Nickel, Lead, Zinc) 3)SVOCs were detected in groundwater at all 10 sample locations GW-1 through GW-10. The concentrations of the SVOCs exceeded the ESLs at all locations. The source of the detected SVOCs is unknown but they could be associated with material combustion, miscellaneous debris,pesticides or other materials. Since SVOCs were detected in groundwater above risked based regulatory screening levels at all 10 previously sampled locations soil and groundwater samples should be collected in additional locations (possibly 3 or 4 locations) situated throughout areas of the site not previously tested. 4)Previous investigators reportedly found TPH as diesel and motor oil, low levels of DDT and DDE, and arsenic infill on the east side of the site. They also reported that there is a large amount of debris in the eastern portion of the site. ROKEN noted at least several feet offill covering the entire site and received reports that there may be large areas of buried debris (contents unknown) in the east-central portion of the site. ROKEN recommends a geophysical survey extending over the entire site to identify the location and general extent of buried objects, debris and/or fill. In addition, shallow soil/fill samples should be collected throughout the site(in conjuction with the sampling recommended above) to characterize magnitude and extent of pesticides and metals in fill. A Remedial Investigation Workplan should be prepared that presents the details of these recommended tasks. Upon completion of Remedial Investigation ROKEN will process the data and prepare a report presenting a site description,sampling methods and procedures, summary of analytical results,and a summary of findings with recommendations, if any. The report will also include site map(s)with approximate sample locations and laboratory analytical reports. Typically this scope of work could be carried out within a 6 week period with a report delivered approximately 30 days following completion of the field work. However obtaining permission to conduct work on neighboring property(s)can significantly delay the process. The actual schedule for this site will be determined upon completion of a Final Remedial Investigation Workplan and obtaining access agreements with neighboring property owners. 15
