CAMBRIA Soil Types Encountered: Soil types encountered while drilling the borings consisted primarily of silt and silty sand with lesser amounts of sand (Appendix B) Soil Chemical Analyses. Soil samples from the well borings were not collected for laboratory analysis as these drilling locations are at or near the locations of previous borings where soil sample analysis was already performed Groundwater Analyses: Groundwater samples from the newly installed wells were analyzed for total petroleum hydrocarbons as gasoline (TPHg), benzene, toluene, ethylbenzene, and xylenes (BTEX), seven fuel oxygenates, and lead scavengers by EPA Method 8260B Groundwater samples from the pre-existing wells were analyzed for TPHg, BTEX, five fuel oxygenates, and for lead scavengers by EPA Method 8260B Soil Disposal. Soil cuttings generated during the well destruction activity were stored onsite, placed on, and covered with plastic sheeting The soil was sampled and profiled for disposal The soil cuttings sample results are contained in Appendix C The soil will be transported to Allied Waste Industries' Forward Landfill in Manteca, California for disposal once we have received approval for disposal from the disposal facility Well Materials. Wells MW-19-81 and MW-19-120 utilized four-inch diameter schedule 40 PVC well casing and Circum-Slot screen Wells MW-11-82/MW-11-122 and MW-18-80/MW-18-120 utilize CMT (Continuous Multi-channel Tubing) well casing The CMT casing is one well casing that allows for multiple screened intervals in one well boring Each CMT well casing is screened at two depth intervals Wells MW-11-82 and MW-11-122 are in one CMT casing and wells MW-18-80 and MW-18-120 are in the second CMT casing Monterey #2/12 sand was use for the filter pack, hydrated bentonite pellets were used for the transitional seals, and cement grout was used to seal the boring 1399 3
