Abstract

Purpose This study was conducted to determine the potential of drinking water treatment residuals (DWTRs) land application in altering the distribution of Cu, Pb, and Ni among soil fractions. The main objectives of the study were to (1) assess the mobility and availability of biosolid-born Cu, Pb, and Ni in two arid zone soils differing widely in soil properties and (2) evaluate the efficiency of inexpensive DWTRs at various rates on immobilization and chemical transformation of Cu, Pb, and Ni in the biosolid-amended soils.
