A field photoionizing hydrocarbon <br /> vapor detector will be tested as an evaluating tool and may prove <br /> to be useful in providing additional evidence of the degree of <br /> soil segregation. The respective soil piles will be isolated <br /> from each other pending chemical analyses to verify the levels of <br /> contamination in both piles. <br /> Applied GeoSystems recommends that both soil piles be temporarlya <br /> placed on two to three layers of 0. 020-inch thick plastic <br /> sheeting (Visqueen) . The sheets should be laid so that sheet <br /> edges overlap by several feet, thus reducing the likelihood of <br /> leachate migratn into the soil below the piles. The ground <br /> i <br /> below the temporary storage piles should be smoothed and sharp <br /> objects removed to reduce the possibility of puncturing the <br /> plastic. <br /> tMoisture in-the piles should be:kdpt.';,to. a minimum to reduce the <br /> probability of leachate formation or migration �y:covering; the; <br /> piles Theov should consist of,,pjastic sheeting, suitably <br /> as chored with weicghta (soil or other heavy objects) to prevent <br /> 5 <br />
