1 kn KLEENFELDER 34 ADVANCEMENT OF PUSH PROBES i ' On Saturday April 12, 2003, five (5) cone penetrometer tests (CPTs), were advanced to a depth of approximately 25 feet bgs A fifth CPT was advanced to a depth of approximately 40 feet to obtain information regarding the lithology in the area for trench stability issues These CPT locations are labeled PT-6 through PT-12 The CPT work and findings will be summan`zed in a separate report, since soil and groundwater samples were not collected from the CPT borings ' Seven pushprobes (GPI through GP-7) were advanced in the Franklin Site Area on April 10, 2003, over approximately 700 linear feet at intervals ranging from 80 to 150 feet The ' pushprobes were continuously advanced in five foot intervals using a pneumatically driven steel probe During advancement of the soil borings the soil samples were logged for lithologic classification based on the Unified Soil Classification System (USCS) The sample probe was ' lowered to the desired sampling depth and driven into the soil A total of seven soil samples were collected, one from each of the pushprobe locations at depths ranging from 9 to 12 %2 feet bgs Soil samples were obtained by inserting acetate liners into the probe and by cutting out the ' desired sample interval from the acetate liners, and sealing the ends with Teflon tape and plastic caps The logs of the pushprobes are located in Appendix A ' After completion of each boring a grab groundwater sample was collected in each of the seven pushprobe bonngs Groundwater was encountered at depths ranging from 10 to 19 feet bgs Groundwater appeared to stabilize at depths ranging from 10 to 12 feet bgs, if boring material Mwas permeable enough to allow groundwater to rise within the boring prior to bonng closure The groundwater samples were collected either by a single use disposable polypropylene bailer or by use of a disposable polypropylene tubing, stainless steel ball valve and PVC piping If the boring was suspected of caving or heaving sands were encountered a 1-inch PVC pipe with a 5 to 10 foot screened interval was lowered into the boring The tubing and check valve was lowered into the piping and groundwater was collected by use of mechanical positive ' displacement The groundwater samples were decanted directly from the bailers or tubing into pre-cleaned laboratory provided bottles for the requested analyses The seven soil and _ groundwater samples collected from pushprobe borings GP 1 through GP7 were analyzed for the following + Total Purgeable Petroleum Hydrocarbons (Gasoline Range) [TPH-G] by EPA Method 8015M/DHS LUFT ' • Benzene, Toluene, Ethylbenzene, Xylenes [BTEX] by EPA Method 80151318260B • Total Lead by EPA Methods • Volatile Organics, including 5 oxygenates (MTBE, DIPE, ETBE, TAME and TBA) by EPA Method 8260B ' 28699 EOl /ST03R759 Page 5 of 17 Copyright 2003,Klemfelder,Inc May 20,2003
