1 <br /> properly labeled & sealed drums. They will be stored on site <br />' pending results of laboratory tests. <br /> 9. As soon as practical after developing, the static water level <br /> in each well will be measured with a suitable electrical inter- <br /> face probe device, using the notched casing as a reference point. <br /> A minimum of 3 casing volumes of water will be purged from each <br /> well using properly cleaned equipment-water will be placed in <br />' suitably marked drums for later disposal . Resistivity, temper- <br /> attire & pH will be measured during purging operations, which will <br /> continue under measurements indicate that well bare conditions <br /> have stablszed. <br /> 10. Water samples will be obtained by use of a clean teflon <br /> bailer or other suitable device, placed in clean glass vials, and <br />' preserved for shipment. They will be delivered to FGL laboratory <br /> under proper chain of custody with instructions to test for $TEX <br /> & TFH-G, using test methods and detection limits as specified by <br /> the County EHD. The County EHD will be notified in advance when <br /> purging and sampling operations will be conducted, <br /> 11. The methods! of disposal of drill cuttings, core samples, <br /> and fluids f rom these wells and prior- activities will be deter- <br /> mined after the results of all laboratory results have been <br /> analyzed. The County EHD will be contacted prior to any action <br />' taken. <br /> Upon completion & sampling operations, and analysis of laboratory <br />' analyzes, a report will be prepared and submitted to the County <br /> EHD for review and response. <br /> Our client as prepared to proceed with this project as soon as <br />' approval is received from the County Environmental Health Depart- <br /> ment. <br /> WI 1 m J.
