Problem Assessment Report November 20, 1990 <br /> Fire Engine Company No. 2, Stockton, California AGS 38009-2 <br /> Disnosal of Drill Cuttings and Pureed Water <br /> ® Soil cuttings and purge water generated during the December 1988 drilling event were <br /> temporarily stored in Department of Transportation (DOT) drums. Four discrete soil <br /> samples were collected from the drill cuttings and composited into one sample in the <br /> laboratory for selected analyses to evaluate disposal options. Applied GeoSystems obtained <br /> an application for authorization of uncontrolled soil aeration onsite from the San Joaquin <br /> County Air Pollution Control District on August 14, 1989. In the May 1990 event the drill <br /> cuttings were stored on and covered with plastic. The purged water from both sampling <br /> events was pumped and stored in approved DOT drums pending laboratory analyses. We <br /> understand from the City'of Stockton that the.driIl cuitings..and the drummed water from <br /> both drilling events were transported and disposed of properly. <br /> SITE CONDITIONS <br /> Geolo2y <br /> The site is underlain by the Modesto Formation, which is divided into nonmarine basin <br /> deposits,fan deposits,and stream channel deposits consisting of clay,silt, and sand (Rogers, <br /> 1966).
