Project No 014-95262 Appendix D Page No 2 pH, chloride, phosphate, nitrate, ammonia-N, and oil and grease Soil samples from hand auger borings near sumps, separators, etc were analyzed for one or more of the following chloride, electrical conductivity, pH, oil and grease Soil samples from adjacent to the former boiler diesel supply pipeline, and from areas previously or currently overlain with spoils from excavation of the former diesel tanks, were analyzed for Total Petroleum Hydrocarbons as diesel (TPH-D), and BTEX/TPH-G 13 Drill cuttings were drummed and stockpiled within the fenced area west of the main plant building Drill cuttings were segregated based upon field observations Rinsate generated during decontamination procedures was drummed and left on- site near the wastewater treatment facility pending analytical results Following favorable analytical results the drum contents may be metered into the normal process waste stream for biologic treatment 14 Equipment used for the advancing of soil borings and the sampling of soils was decontaminated (steam-cleaned, TSP, lab-grade detergents, etc ) before arriving on-site, between each boring and/or sampling, before leaving the site, or as ' necessary to minimize the chances of cross-contammation The rinsates from the cleaning were contained and drummed The water was stored on-site pending the results of the chemical analysis and proper disposal by the client with the assistance of Krazan& Associates, within 90 days following generation 15 Nine Hydropunch* II sampling points were placed at various locations at the subject site to assess the distribution of constituents of concern in groundwater Please refer to the attached map for the Hydropunch'II sampling points 9 ' 16 Prior to driving the Hydropunch'II probe with a cone penetration testing (CPT) rig, an existing monitoring well was sounded to determine the current depth to l groundwater beneath the subject site area 17 A groundwater sample from location HP-6 collected using the Hydropunch' II sampling tool When positioned below the groundwater surface and locked in place, the sleeve is retracted exposing a section of PVC well screen Groundwater enters the well screen with no aeration Once the well screen is filled, accumulated groundwater was collected using a Teflon bailer 18 Due to difficulties in obtaining a water sample, caused by clogging of the screen of the Hydropunch 11 sampling tool, all remaiung water samples were collected 1 by pushmg rod without the Hydropunch B tool attached Only a sacrificial tip was ' placed at the end of the rod The drill rod was pushed to the target depth and then extracted a few feet separating the tip from the rod and creating a cavity into which groundwater flowed A Teflon bailer was lowered down the center of the rods to collect accumulated water,just as if using the Hydropunch R tool 19 The collected samples were transferred from the bailer to appropriate sample containers using a bottom emptying device (Teflon check valve and nipple) minimizing loss of volatile constituents The samples collected were preserved in 1 I, ' KRAZAN& ASSOCIATES, INC Offices Serving the Western Untied States 95262 APD
