The samples will be collected at five-foot intervals, at intervals of obvious contamination and at stratigraphic features of intere'st. Soil samples may be field screened for the potential presence of contaminants by' using a field photoionization meter of the Hanby Field Analytical Laboratory (a semi-quantitative measurement). Soil engineering field measurements for strength 1�will 'be collected as well as physical samples for laboratory soil strength testing. Upon completion of the borehole drilling and collection of information, the boreholes will be backfilled with grout, placed from the bottom to top of the borehole. I'E Groundwater Sam 1 i n Each exploratory boring will be sampled. The ground kater samples collected from the boreholes will be used for a rapid reconnaissance of the site groundwater contamination. A brief summary of these procedures follows: Each borehole will be advanced into the aquifer and temporarily cased. The water entering the borehole will be sampled using a clean bailer, and carefully !j poured into the appropriate laboratory prepared container with minimum cavitation.11 Each water sample will be labeled, logged onto a chain-of-custody form, and placed in a chilled ice chest. Upon completion of the borehole sampling, the borehole will) be sealed: I � Chemical and Physical Analysis Up to six soil samples and up to three groundwater samples will be analyzed at a State certified analytical laboratory for contamination. Selected samples will be tested for 't the following; Total Petroleum Hydrocarbons as Aviation . Gasoline (TPHAG), Total Petroleum Hydrocarbons as Jet A fuel (TPHJA), Kerosene (K), Benzene (B), Toluene M (T), Eth lbenzene (E), Xylene X using EPA Methods 3550 35101$015 8020. The analyses will be run on an "rush" turnaround (one working, day). I ` Selected soil samples will be tested for physical pro,pertie's for soil engineering I strength purposes at a geotechncial soil laboratory. It is `anticipated that two soil t samples will be tested for moisture content, sieve analysis, shear test, and I compressive strength/bearing capacity. These soil engineering data will be forwarded to the civil engineer for his design analysis: Report Ili E A report of the findings of this site investigation will�be prepared. The report will include the field methods, permits, exploratory boring logs, chemical analytical data and report narrative. The report will include estimates of contaminant extent (if any) with conclusions and recommendations. The soil engineering analysis will be completed by the civil engineer under a separate letter and submitted with t h e underground storage tank installation permit application. iif you have any questions, please call.
