ATTACHMENT A -2- <br /> MONITORING WELL WORKPLAN AND REPORT REQUIREMENTS <br /> E. Well Development <br /> Well development must be performed at least 48 hours after the sanitary seal has been placed, <br /> and must include' <br /> ■ Method of development to ensure maximum removal of fines from the vicinity of the <br /> screen and to ensure free-flow of fluids (i.e., over-pumping, air-lift, surge block and <br /> bailer,jetting, etc.), <br /> ■ Parameters to be monitored during development and the record keeping procedures, <br /> ■ Method of determining when development is complete, <br /> ■ Disposal of development water. <br /> F. Well Survey- Horizontal and Vertical Coordinates <br /> ■ Name of the Licensed Land Surveyor or Civil Engineer, <br /> ■ Datum for survey measurements, <br /> ■ List of well features to be surveyed, including the top of casing, ground surface, and <br /> horizontal and vertical coordinates, <br /> Accuracy: Horizontal must be within +0.1 foot and Vertical within +0.01-foot: <br /> G. Water Level Measurement <br /> ■ The elevation reference point at each monitoring well must be within 0.01-foot, <br /> ■ Ground surface elevation at each monitoring well must be within 0.01-foot, <br /> ■ Method and time of water level measurement must be specified <br /> H. Sampling and Laboratory Analysis <br /> Groundwater sampling must be performed after the well is developed, and analytical results <br /> must be included with the monitoring well installation report. Groundwater sampling, field tests, <br /> and laboratory analysis must comply with the requirements in the Waste Discharge <br /> Requirements, Monitoring and Reporting Program, and Standard Provisions. All Method <br /> Detection Limits, Practical Quantitation limits, and "trace" concentrations must be reported on <br /> the laboratory reports, as required in the WDRs. <br /> 1.
