IFile No. 94342-QM94 Page 2 <br /> The PH, conductivity, and temperature of the groundwater were <br /> monitored to determine the stability of groundwater quality <br /> conditions prior to sampling. The wells were purged with a clean <br /> teflon bailer. <br /> All sampling tools, including measuring tapes and purging equipment <br /> were washed in Alconox detergent solution and rinsed with tap water <br />' and then in deYon.ized water to eliminate cross contamination. New <br /> strings were attached to each teflon bailer prior to sampling each <br /> well. <br />' After a short pause between the purging and sampling, the <br /> groundwater samples were obtained by utilizing a clean teflon <br /> bailer with a new nylon string. The water was then poured into two <br />' 40-m1 vial bottles for gasoline and BTEX and into two one liter <br /> bottles for diesel content. All groundwater samples were properly <br /> labeled after their collection and then placed in an iced cooler <br /> for transfer to a State certified laboratory under the chain of <br /> custody, for analyses. <br />' 2 .2 LABORATORY ANALYSES <br />' Samples obtained from the site were analyzed for total petroleum <br /> hydrocarbons as gasoline and diesel plus BTEX (Benzene, Ethyl- <br /> Benzene, Toluene, and Xylenes) EPA method 5030/8015/3510 . <br /> 1 <br /> 2 . 3 GROUNDWATER DISPOSAL <br />' Groundwater generated from development of the monitoring wells was <br /> stored in 55 gallon steel drums on-site. The drums will be disposed <br />' of by the owner, using a firm licensed to transport and dispose of <br /> hazardous materials. <br />' 2 . 4 FLOATING PRODUCTS <br /> No floating products or sheen were encountered in any of the <br /> monitoring wells sampled on this site. <br /> ADVANCE SOIL TECHNOLOGY,INC <br />
