f SITE CONDITIONS AND THE GROUNDWATER f In general, all of the soil bonngs report the same geologic the water table grade from sandy silts to silty clays to a ( water bearing aquifer begins at forty-five feet below the surface. Silty sands are directly below the aquifer and th Pump Test Report 6/6102). NO characterization of the site. The soils above tth of forty-five feet below the surface. The [rface and continues to sixty feet below the depth is unknown (See ATC Groundwater The soils of the aquifer are classified as clean fine gravely sands. All of the soil borings indicate that the contamination is confined to this fifteen foot aquifer. he hydraulic gradient of the water table is between S = 0.001 and S= 0.002 with down slope in the south to southeast direction. This aquifer appears to have a high permeability. SCOPE OF WORK This work plan is developed to. answer questions concer and extent of the underlining aquiclude. One CPT is 1 determine the lithology below the limits of the existing of the existing extraction well (EW -1). The resistance ( bgs. The sample push run will retrieve four samples of I Soil and groundwater samples will be analyzed as desc! PROCEDURE Push Procedure The area around the selected push point has been develo; 8" of concrete. The concrete paved driveway will be col the push run and the sample run of the CPT. The first pi and pore pressure for the lithology graph. Selected areas push for analysis of both soil and groundwater. Soil Sample Transportation and Analysis Soil samples will be extracted with a metal liner that will secured with a standard plastic cap. The cap will be sec ice for transport under a chain of custody to a state-certi The samples will be analyzed by EPA methods 8015,1 and the findings presented in a standard engineering Water Sample Transportation and Analysis Water samples from CPT extractions will be transpor preservatives, under a chain of custody, to a state-approv 8015, 8020, and 8260 for oxygenates (incl. 1,2 -DCA & REPORT OF FINDINGS An engineering report will be issued covering findings results of laboratory analysis for the samples extracted. 2 the total depth of the contaminated aquifer )sed to be pushed to a depth of 75' bgs. to bores. The CPT will be located in the area push run will determine lithology to +/- 75' ndwater and four soil samples for analysis. I below.
