CONCLUSIONS

The following conclusions were drawn frc the prelfbullinary analytical dati and operations obsentd at the Oouglassvtlle Pennsyhanfl Superfund Site

1 The vol_ of the soltdtf1td sofls ustng the HAZCON process at Douglassvtlle resulted tn an tncruse of approxfNtely 1001 when c-red to the vole of the untreated sot 1s

2 The unconftntd c011preuhe strength ranted frc 200 to 1500 psi and was tnrsely proportional to the oil and grease concentration

J The TCLP 1uch1ng tHts for tho so11difitd soils produced very low levels of Mtals valatfle organics and sbullholattle orgAnics tn the luchate However for the organtcs the leachate concentrations were approxtNtlly equal for the treated and untreated sons
