Disposal Of Purge Water Only very low levels df either metallic ora anic•contaminants have � been detected in some of the wells downgradient of WMU A. Because these levels arc very*low, there is not tient reason to containerize the purge water. Should the analytical is indicate a need to containerize,the fella procedure will be used: Sample 'purge water.Zenerat6d during well.purging; and excess water generated during z4 mpling, will be placed in a trailer mounted tank attached to. the sampling vehicle. •.When the tank is full,.the groundwater will be pumped.from the tank to an ansite leachate evaporation pond. After the groundwater sampling round is completed the tank-will be filled with approximately 100 gallons of water from the water trick fill station..-This water will then be recirculated in the tank and pump to ainse the system. The rinse water will then be discharged to the leachate.evaporation pond.. Domestic Well The.domestic well sampled (DW-9,690) contains.a.submersi'blepump wittL as un-lint pressure tank and switch to activate the pump -once-the-pressure_4r9ps below a certain value,. The.sample �.. point for DW 9690 was a spigot directly. attached to the p�tank Water samples were not collected directly from the•well because the aboveground plumbing and submersible pumps - would need•to be removed_ Prior to collecting the watcr-samplcs,the pump was.allowed to run ' for approximately 30 minutes to purge the water-system,and draw groundwater from-the aquifer_ During .sampling, the pumps cycled on-off because the pumptag rate exceeded the spigot discharge, LANDFILL,GAS _ Landfill gas monitoring at Forward Landfill consists of monitoring gas in the ten interim gas probes and in buildings located at the landfill hcility. -483849-F01\23 - I OR325 A-1 1 July 14,2040 co¢rri&M Kkwelda.!ac
