Compatibility of Compacted Soils with Municipal Waste Combustion Ash Leachates
Hydraulic conductivity values for three compacted soils were used as indices of compatibility of the soils with two municipal waste combustion (MWC) ash leachates. Specimens of the three soils were compacted to 90% of proctor compaction (ASTM D 693) in double-ring permeameters and permeated first with water (0.005 N CaSO4) and then with MWC ash leachate. The hydraulic conductivity values of the soils did not change significantly after passage of more than two pore volumes of either MWC ash leachate. All three compacted soils were compatible with both MWC ash leachates.
