Upon arrival at the well location, perform field level risk assessment to <br /> determine location is safe to perform surface water sampling. Document risk <br /> assessment with field level risk assessment form. <br /> 2. With well location determined to be safe, complete a visual inspection of well <br /> vault/ monument, casing, site condition and if a dedicated pump is present <br /> 3. Measure the static water level in the well and record measurement listed as <br /> (depth to water). Water levels should be measured with a precision of+ 0.01 <br /> foot. <br /> 4. Decontaminate water level meter after use. <br /> 5. You may calculate the volume of water in the well to aid in the purging process, <br /> there is no required purge volume for the EPA low flow sampling standard, <br /> rather it is based on parameter stabilization. <br /> a. 2in = 617m1/ft <br /> b. 4 in = 2470 mI/ft <br /> 6. Insert decontaminated pump and tubing into the well descending slowly until <br /> pump is in the desired screened interval, avoid letting the pump come in <br /> contact with the well bottom. Ensure pump is lowered into the well slowly to <br /> avoid turbidity. <br /> 7. Attach the discharge tubing to the bottom port on the YSI water quality meter <br /> • flow cell. <br /> 8. Connect the pump to the controller with the cord provided <br /> Department THIS DOCUMENT IS UNCONTROLLED IN HARD COPY FORMAT Doc Id: <br /> SIR Date of This Issue--/--/-- Date of Next Review:--/--/-- Page 56 of 73 <br />
