ATTACHMENT A -4- <br /> MONITORING WELL WORKPLAN AND REPORT REQUIREMENTS <br /> n. Boring diameter <br /> o. Casing diameter <br /> P, Casing material <br /> q. Size of perforations <br /> r. Well elevation at top of casing <br /> S. Initial and stabilized depth to groundwater <br /> t. Date of water level measurement <br /> U. Monitoring well number <br /> V. Date drilled <br /> D. Well Development <br /> 1. Date(s) and method of development of each well, <br /> 2. Method of development, <br /> 3. How well development completion was determined, <br /> 4. Volume of water purged from well and method of development water disposal, <br /> 5. Field notes from well development. <br /> E. Well Survey <br /> 1. Coordinate system, epochs, bench marks, horizontal controls, accuracy, and precision, <br /> 2. Survey results of casing elevation with the cap removed (vertical to 1/100th foot) and the <br /> ground surface, <br /> 3. California Registered Civil Engineer or Licensed Surveyor's report, field notes, and <br /> stamp/signature in an appendix, <br /> 4. Description of the measuring points (i.e. ground surface, top of casing, etc.), <br /> 5. Tabulated survey data with well numbers and horizontal and vertical coordinates. <br /> F. Laboratory Analytical Results <br /> Laboratory analytical results must be included with the well installation report. All analytical <br /> reports prepared for the Discharger's facility must contain, at a minimum, the information within <br /> this section. <br /> 1. Tabulated field and analytical data with sample location identification numbers, water <br /> quality goals, field/analytical results, and highlighted data that is outside water quality <br /> goals, <br /> 2. Appendix with laboratory reports, COCs,and laboratory signatures on reports, <br /> 3. Laboratory reports showing results, reporting units, MDLs, PQLs; "trace"results,flagged <br /> results, matrix effects, and QA/QC results, <br /> 4. Piper Diagrams and Stiff Plots comparing upgradient and downgradient water quality <br /> parameters, <br /> 5. Discussion of results including, but not limited to; discussion of violations, exceedances, <br /> if all field and monitoring parameters were sampled and analyzed, description of <br /> groundwater flow direction, comparison of analysis and field sampling results to <br /> background and water quality goals, list of potential constituents of concern at each <br /> sampling location, and other relevant discussions, <br />
