u <br />7 <br />The total analysis will measure the sum of the compounds distributed <br />in the soil -pore liquid and that absorbed onto the soil. This will <br />provide a conservative evaluation of site leakage. <br />Two unsaturated zone sample depths have been selected for soil charac- <br />terization to best comply with the SWAT regulations: (1) 20 feet in <br />the shallow borings and (2) 20 and 200 feet in the deep borings. <br />Two soil samples for laboratory analysis were collected from depths of <br />20 and 200 feet in Boring MW -1. The samples were analyzed for vola- <br />tile, semivolatile and nonvolatile organic compounds and chlorinated <br />pesticides. With one exception, none of these compounds were detect- <br />ed. The soil sample collected at a depth of 200 feet was reported to <br />contain 12 micrograms per liter (µg/1) toluene. This is an anomalous <br />result, since toluene was not detected in the shallow soil sample or <br />in the ground -water sample from Well MW -1. The reported detection of <br />toluene is not thought to be significant (EMCON Associates, 1988). <br />This concludes the SWAT proposal for the Corral Hollow Sanitary <br />Landfill.
