Abstrakt:	The article presents a study on the effects of entrenched biosolids stabilization type and rate on the chemistry and mobility of heavy metals. The study involves two rates of biosolids which were anaerobically digested by Alexandria Sanitation Authority in Virginia and lime-stabilized by Blue Plains Sewage Treatment Plant in Washington, D.C., and were then placed in trenches at a mineral sands mine reclamation site in Dinwiddie County, Virginia in the summer of 2006. Furthermore, the result shows that the anaerobically digested biosolids and control have produced less cumulative metal mass transport for copper, nickel and zinc than the line-stabilized biosolids.
