ATTACHMENT 2 -2- 16 JUNE 1987 <br /> -Elevation reference point at each monitoring <br /> well with an accuracy of . 01 feet. <br /> -Ground surface elevation at each monitoring <br /> well with an accuracy of 0. 1 feet. <br /> 2 . Water and soil quality data: <br /> -Report water and soil analysis results for <br /> all known fuel constituents. <br /> -Report results for other analyses which may <br /> be indicated by background investigation. <br /> -Detailed sampling and analysis methodology <br /> and protocol is to be included in the <br /> workplan. <br /> -Quality Assurance/Quality Control program. <br /> -Identify analytical laboratory. <br /> -Proposed schedule for ground water quality <br /> monitoring program. <br /> 3 . Hydrogeological characterization. <br /> -Piezometric surface map. <br /> -Proposal for logging of boreholes, and <br /> characterization of site geology. <br /> -Identify unconfined or confined aquifers. <br /> -Water levels at each well. Indicate <br /> frequency of measurements. <br /> -Identify water table gradient for each date <br /> water levels are measured. <br /> -Identify barriers to ground water flow. <br /> 4. Proposal for characterization and proper <br /> disposal of contaminated soil and water <br /> removed in the course of the investigation. <br /> -Borehole cuttings. <br /> -Water generated during development and <br /> purging of welis. <br /> 5. Name persons responsible for investigation <br /> and final report. <br /> 6. Workplan is to detail: <br /> -The specific tasks completed. <br /> -Those tasks necessary to completely define <br /> the extent of ground water and soil <br /> contamination. <br /> -Those tasks necessary to assess the the <br /> impacts of soil and water contamination at <br /> the site on the water quality in the San <br /> Joaquin Delta. <br />
