Disposal Of Purge Water <br />0111Y VOY low levels of either metallic or organic contarninaitts have been detected in some of <br />the wells downgradient of WMU A. Because these levels are vcry"low, there, is not sufficient <br />zwwn to containerize the purge water. Should the analytical results indicate a need to <br />containerize, the following proced= will, be used: <br />Sample purge water generat6d during well.purging, and excess water generated during <br />sampling, will be placed in a tafler mounted tank attached to- the sampling vehicle. <br />When the tank is full. the grottridwater will be pumped from the tank to an onsite leachate <br />evaporation pond. After the groundwater sampling round is completed the tank will be <br />fiUltd with 2PPro.-dulatelY 100 gallons of water from the water truck fill station._TILi.S <br />'Water Will then be recirculated in the tank and pump to Anse the system- The ruse water <br />will then be discharged to the leachate.evaporation pond__ <br />T114. domestic well sampled (D W-9690) contaim.a _submc=-blIC pump vfitb- an in-line <br />Pr`CSsUrC <br />tank and switch -to activate the pump once- the pressurc-drops below- a certain value--. 1ht--sample <br />point for -DW-9,690 was -a spigot directly attached to the presswe tauk- Water <br />samples v,,Vxe not <br />collected directly from the - voell becatise the aboveground plumbing and submersible PUIMPS <br />would need. to be removed- Prior to collecting the wat= samples, the pump was. <br />allowed to run <br />for approximately 3 0 minuties to, purge the water system and draw Mundwater from -the aquifer. <br />During sampling, the pumps cycled on-off because the pumping rate exceeded the spigot <br />discharge, <br />lffl�rl MOVI <br />.11.■: 1 raf <br />I1 1ru,11IRM <br />23493944-FOI1231OR3Z A -I I July 14, 2000 <br />2Q00 lCkintct�r. tae. <br />64 <br />
