As soon as practical after development, the static water level in each well will be <br /> measured by a suitable electrical interface probe device, using the notched casing as <br /> a reference. A minimum of 3 casing volumes of water will be purged from each well <br /> using properly cleaned equipment. Removed fluids will be placed in suitable_ <br /> containers, properly identified, and stored on site for later disposal. Resistivity, <br /> temperature, and PH will be measured. and recorded during purging, which will <br /> continue until well bore conditions stabilize. <br /> 10. Water samples will be obtained by use of a clean teflon bailer or other suitable <br /> device, placed in clean glass vials, and preserved for shipment to a State Certified i <br /> laboratory for analysis. They will be delivered under proper chain of custody with <br /> instructions to test for BTEX, TPH-gasoline, and soluble lead using methods and <br /> detection limits as specified by the San Joaquin County EHD.
