^^ 4 Union Ice plant Phase I & I1 Remedial Investigation plan Page: 6 will be immediately sealed in their liners using siuminum foil lined plastic caps that are taped in place. The remaining sample will be removed from its liner to be used as an aide to the on-site geologist in logging the material at that dept!-. Soil samples collected for analysis will be analyzed using EPA method 8015 modified, total petroleum hydrocarbons, and 8010/8020 for pergeable aromatics and halocarbons. 3.5 Ground Water Sampling A laboratory provided travel blank will accompany the sample 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 listed on the Chain of Custody but will be analyzed only if all samples contain, the same contaminants. 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 between 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 contaminants.' Immediately prior to sampling, water levels and well depth measurements will be taken in all wells at the site. Each well will be evacuated using a stainless steel bladder pump, which does not introduce air into the water column, or a teflon boiler. The pH, temperature, and electrical conductivity of the water will be monitored as the well is evacuated. These parameters will be noted on a field log. Instruments calibrated to known standards will be used to monitor these parameters. At least 5 well. volumes will be r
