will be placed 2 to 3 feet above the sand and the remainder of the well annulus will be. filled with cement. Each well will.have a traffic-box with locking cap and lock. At least 48 hours after the wells are constructed, the depth to water will be measured -and the wells will be developed by removing groundwater until the return water is free of sediment. After the development, the water will continue to be removed until the pH, conductivity and temperature=stabilize at which time a water sample will be taken and 1 sent to the laboratory for diesel analyses. The-top of the casing will be surveyed to- elevation. - LABORATORY ANALYSES The tanks at or near this site_contain only diesel,-therefore the soil and water samples Will be tested as follows: - SOIL 'Method - Detection limits EPA 8015 Diesel 5 mg/Kg_ Water EPA 8015 Diesel 50 ug/L7 EPA.602/8260B_ BTEX -0.5/1 ug/L - REPORT When all the data is received a report-of the findings will be prepared showing the ' geologic and laboratory results.-Based upon the results, further recommendations will be suggested, if required. PERMITS We will obtain from the Environmental Health Department San Joaquin County a'drilling _. permit. US Alert will 6e notified at least 72 hours prior to the start of drilling. If _ ' underground utilities are in-conflict with a boring location, the well will be moved to the nearest location of the original site. Once this work plan is approved by the Environmental.Health Department San Joaquin County the following-schedule will be followed: Obtain Drilling Permit = 33 weeks- Schedule eeks Schedule Drilling - 4 weeks Drilling Wells and.Installation 1 week Develop Wells and Survey 5 weeks - Laboratory Analyses and Prepare Report 5 weeks
