Influent, treated biosolids, and effluent waters were collected from five Wastewater Treatment Plants in Savannah, Georgia. The result of this study indicated that there were significant differences in the elemental composition of influent, biosolids and effluent waters collected from various Wastewater Treatment Plants. The samples differed in pH, dissolved oxygen, salinity, nitrate nitrogen, phosphate, elemental concentration and organics. Most trace elemental concentrations were observed at the Crossroads Wastewater Treatment Plant. This was probably due to industrial sludge and domestic sludge is being disposed to this plant. The highest amount of carbamazepine was observed in President Street Wastewater Treatment Plant. Our study suggests that careful consideration should be given when reusing the treated biosolids and/or effluent for land application to avoid further contamination of various heavy metals and organics from these potential sources.
