| Abstract |
Land treatment of wastewater sludges from tannery processes has been investigated during a five-year field plot study. The experimental design included eight field test plots receiving selected applications of three types of tannery sludges over a three-year period. The five-year study included analyses of sludge, soil core, plant-tissue, and soil pore and runoff water samples to evaluate the feasibility of land treatment of tannery sludges. The data generated indicated that land treatment is potentially an environmentally acceptable technology for management of wastewater sludges from trivalent chromium tanneries; however, waste application rates must be carefully controlled. The applied trivalent chromium appeared to remain primarily in the topsoil without any detectable oxidation to hexavalent chromium. Transport of trace quantities of chromium in soil runoff water appeared to be associated with movement of soil particles. |
