I Well Development and Sampling 'a The well was developed until tie well water appeased clear of sediment. The t water produced during well development was containerized and left on-site in 55-gallon drum for disposal as hazardous waste if deemed necessary upon receipt of laboratory results. Disposal will be the responsibility of the client g` unless other arrangements have been made. All soil and ground water samples were properly labeled with date collected, £ project numbs, sample coordinator, and sample identification. Field records document the above information and other significant data. { The samples were refrigerated immediately for delivery to the laboratory and were not opened by anyone other than laboratory personnel. Chain of Custody records were maintained at all times. Soil Sampling All soil sampling equipment was thoroughly steam-cleaned before and between sampling to prevent cross contamination. Relatively undisturbed soil samples were taken at intervals of not more than 5 feet in order to evaluate the subsurface materials. The soil samples were taken using a California Modified Split Spoon sampler with brass liners. The sampler was driven by a 140 pound hammer repeatedly falling 30 inches. The Glow counts necessary to drive the sampler was recorded for each 6-inch interval to help evaluate the consistencies of the materials. The Iaboratory samples did not have head space and were immediately sealed in their liners using aluminum foil lined plastic caps. The remaining sample was removed from-its liner-and used as an aide to.the on-site-geologist in-logging the -------- ---: -- material at that depth. r= Soil samples collected for analysis were analyzed using EPA method 8015 �., modified for total petroleum hydrocarbons, EPA method 8020 for BTX&E
