Once the depth to water is known the tape and probe will be <br /> withdrawn from the well and thoroughly dried. A small amount of <br /> ��- water paste will be placed on the axis of the probe and the <br /> — <br /> probe will be lowered to the water table. Care will be taken to <br /> not allow the probe to descend into the water below the contact <br /> ~� point. Then the probe will be withdrawn rapidly and inspected <br /> for signs of fluid above the contact point. If fluid is noted <br /> the is will be smelled to verify it is fuel , then the thickness <br /> of the fuel will be noted on the measuring log. <br /> Water samples will be obtained as follows: <br /> A) First one full well volume of water will be withdrawn from <br /> the well ; <br /> +~ B) The parameters of Ph , Conductivity, and Temperature will be <br /> measured; <br /> ~� C) A 2nd and 3rd well volume of water will be withdrawn and the <br /> parameters remeasured , if the results vary by more than 10% then <br /> step C is repeated; <br /> -� D) The well is allowed to recover to 80% of its original volume <br /> or 2 hours have passed then a sample will be withdrawn and <br /> placed in its appropriate container. <br /> Purged water will be placed in a drum sealed and left at the <br /> site until its hazardous condition is assessed. <br /> Each well site will be surveyed to within (). 5 Ft. horizontally <br /> and to within 0. 01 Ft. vertically. The elevation to the top of <br /> the casing in each well will be measured with a spirit level and <br /> *� surveyors rod. The leveling will take place at least 24 hours <br /> after the casing seal and traffic box have been set. <br /> ~� Water samples will be taken from the water at or near the <br /> surface of the water table, unless otherwise indicated. Water <br /> will be placed within the prescribed container for the tests <br /> required. The containers will be filled so that zero headspace <br /> *� is present in the sealed vial , one drop of concentrated HCL will <br /> be placed in the vile then they will be placed in a cooler <br /> containing ice until delivered to the lab. The sample must be <br /> ~~ tested by the lab within 14 days. Trip blanks will accompany all <br /> sample containers. A Chain of Custody will be filled out by the <br /> ' sampler , detection limits must be supplied by the laboratory. <br /> = <br /> Well or Boring Abandonments: <br /> All wells and borings will be destroyed once no longer needed. <br /> ~� The following steps will be followed: <br /> ' <br /> ^- 1 . Check well to see if the hole is open to its original drilled <br /> ~~� depth , if not clean out the hole. <br /> ` <br /> �~ 16 <br />
