PROCEDURES <br /> On 30 August 2000, six soil probe borings (B-1 through B-6) were advanced at the site as part of <br /> 1 assessment activities related to an unauthorized release of petroleum hydrocarbons from surrounding <br /> sites The field work was conducted as outlined in the Preliminary Phase H Site Assessment Work <br /> Pian dated 18 August 2000 <br /> 1 <br /> 21 DRILLING ACTIVITIES <br /> 1 Soil probe borings B-1 through B-6 were advanced utilizing a van-mounted GeoP robe 5400 <br /> equipped with 1 125-inch diameter probe rods with an attached 2 15-mch diameter soil sampler, <br /> using "direct push" technology Soil probe borings B-1 through B-6 were advanced vertically to a <br /> depth of 15 feet bsg Ground water was encountered at an approximate depth of 10 feet bsg in the <br /> borings <br /> 1 <br /> 1 2 1 1 Soil Sample Collection <br /> Discrete soil samples were collected at 5-foot intervals,beginning at 5 feet bsg, to total depth of each <br /> 1 boring Soil samples were collected using a Geoprobe soil sampling assembly loaded with four pre- <br /> cleaned 1 125-inch by 6-mch brass sleeves Soil samples were preserved by covering both ends of <br /> the brass sleeve with Teflon sheets, capping, and sealing with tape Each sample sleeve was labeled <br /> ' with soil probe boring location, depth, time, date and sampler's initials The samples were then <br /> stored in a chilled container <br /> 1 2 1 2 Ground Water Sample Collection <br /> ' Grab ground water samples were collected from probe borings B-1 through B-6 using a temporary <br /> PVC screen The probe rods were advanced to a depth approximately four feet below the water table <br /> The hollow steel rods were then pulled out, and a screened casing was inserted into the saturated <br /> ' zone Ground water was allowed to enter the casing, and samples were retrieved using a modified <br /> PVC tubmg bailer Sufficient sample was collected from boring B-1 through B-6 to fill one 1-liter <br /> amber bottle and three 40-m1 EPA-approved VOA vials containing 0 5 ml 18% hydrochloric acid <br /> ' as a preservative Ground water sample containers were labeled with probe boring designation,date, <br /> time, and samplers mitrals The samples were then stored in a chilled container <br /> i <br /> 1 � <br /> Advanced GecEnvironmentai,Inc <br /> i <br />
