Abstract: This study investigated the impact on water quality of sustained discharge of treated wastewater effluent on the wetland commonly known as Weed Lake. A field sampling program was conducted during the months of May through September. Various physical, chemical, and biological analyses were performed on retrieved water samples. EC and TDS values increased both spatially and temporally from the south to the north quadrant of the wetland. Similar patterns were also observed for HPC and coliforms CFU enumeration. Turbidity and TSS decreased from May to June and then surged slightly while typically remaining constant from June to September. COD and TKN were found to decrease from May to July and to increase marginally from August to September. Potentially mineralizable nitrogen and phosphorous were ascertained as indices of the wetland sediment capacity for mineralizing both nutrients. Batch isotherms of PO4-3 were conducted for interaction determination with the wetland sediments.
