Abstract: This study was undertaken to assess heavy metal compositions in the sludge produced at the Glen Valley Wastewater Treatment Plant. Arsenic (Ar), Nickel (Ni), Lead (Pb) and Zinc (Zn) were monitored using methods by the USA EPA and using Shimazu Atomic Absorption Spectrophotometer. Heavy metals composition ranges obtained in the sludge were 0.75-1.23, 27.3-33.1, 445-482.1 and 291-446.1 mg kg 1, respectively for Ar, Ni, Pb and Zn. These levels were within the composition of heavy metals concentrations documented for sludge in, use and disposal of municipal sludge in the United States of America. More research must be done to ascertain the levels of heavy metals concentrations in sludge that will trigger bioaccumulation in crops to hazardous levels and because all the metals studied were identified in the sludge, disposal methods must be adequate to prevent environmental pollution since at their present levels, they are potential pollutants.
