3 of S Pages <br /> Prior to removing any equipment from the hole the TD will be <br /> measured Once the casing is placed in the hole an accurate <br /> measurement of the total amount of casing must be made. The <br /> diffetencc between the two figures will be explained by the well <br /> logger <br /> Completion. <br /> Slotted casing (0 02 inch slots ) will be capped with a bottom <br />' plug The slots will extend to within 10 feet of the ground <br /> surface. Clean 0 3 sand will be placed opposite the slotted <br /> casing and 2 feet above the last slot Directly above the sand <br /> a 3 foot plug of bentonite will be placed Above the plug a <br /> seal of cement will be placed to the surface The top of the <br /> casing will be capped and a traffic box and will be cemented <br /> in place around and above the top of the casing <br /> The well will be developed by bailing within a day of drilling <br /> to remove most of the sediment within the casing and to remove <br /> bridging fines within the slots and sand This will be done by <br /> surging using the well water if possible, if not then only <br /> potable water may be used. Bailing and surging will continue <br /> until the water does not contain any fine silt and or clay. <br /> Sampling Protocol <br /> Soi1 <br /> Soil samples will be obtained from the core samples taken every <br /> 5 feet during drilling The samples will remain within the <br /> brass sleeve covered with aluminum foil, and capped with the <br /> plastic caps which are supplied with the sleeves The plastic <br /> cap will be taped to the brass sleeve using electrical tape so <br /> that an air tight seal is obtained Samples will be marked and <br /> placed in a cooler of ice until they are turned over to the <br /> laboratory, which should be within 48 hours of the drilling A <br /> Chain of Custody will be filled out by the sampler <br /> Water <br /> Water samples will be obtained as follows <br /> A) First two full well volume of water will be withdrawn from <br /> the well , <br /> B) 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 or 2 hours have passed then a sample will be withdrawn and 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 /> Water samples will be taken from near the surface of the water <br /> table, unless otherwise indicated Water will be placed within <br />
