Uujolr Ice C0171pally, Union Street Please If Remedial Work 11a11 Page 5 The soil samples will be taken using a California Modified Split Spoon sampler with brass liners. The sampler will be driven by a 140 pnund hammer repeatedly falling 30 inches. The blow Counts. necessary to drive the sampler will be recorded for each six inch (6") interval to help evaluate the consistencies of the material. The laboratory saillples will not have ]lead !;pace and will be immediately scaled in their liners using aluminuin foil lilted plastic caps that are taped in place. The remaining simple will be removed from its liner to be used as an aide to the on- site geologist in logging the material at that depth. Soil samples collected for analysis will be analyzed using EPA Method 8015 modified, total petroleum hydrocarbons, and 8010/8020 for purgeable aromatics and halucarbons. 5.5 Ground Water Salrlplillg A laboratory provided travel blank will accompany the simple vials from the time they are picked up from the lab to the time they are delivered to the lab. This travel blank should be lister; on the Chain of Custody, but will be analyzed only if all samples contain elle Baine contaminates. All sampling equipment, including the pump, bailer and cables, used by sampling personnel will be disassembled, if appropriate, and steam cleaned prior to commencement of sampling. These procedures will also be followed be- tween each well, sampling point, and at the end of the sampling day. De-ionized or organic-free water (also provided by the laboratory) will then be introduced into the pump or bailer as a final stage of cleaning. This water will then be pumped or gently poured into sample vials to be used as pump or bailer blanks. These blanks will be tested only if their corresponding samples are found to contain contaminates. Immediately prior to sampling, water level and well depth measurement will be. taken in the well at the site. The %veil will be evacuated using a stainless s[eel bladder pump, which does not introduce air into the water column, or a Teflon bailer. The pH, temperature, and electrical conductivity of the water will be monitored as the well is evacuated. These parameters will be notes] un a field log. Instruments calibrated to known standards will be us_d to monitor !hese parameters. At least five (5) well volumes-will be evacuated from the well and more, if necessary, until the above parameters have stabilized. If the well is de- watered before evacuation of five (S) well volumes has been accomplished it will be sampled upon 80 percent recovery of the initial water level. The sample
