Background: This study aims to evaluate the quality of treated wastewater flowing in Zarqa River determine its suitability for agricultural use. The assessment is based on physicochemical and biological parameters accordance with Jordanian standards (JS 893:2021), CCME water index, weighted arithmetic index (WAWQI). Additionally, a microbial was conducted identify presence pathogens wastewater. Methods: A total 168 samples were collected from seven different sites along over 24-month period. focused selected JS 893:2021, including dissolved solids (TDSs), biochemical oxygen demand (BOD), (DO), chemical (COD), E. coli levels. Furthermore, data gathered additional such as pH, mineral content (including Na, Ca, K, Mg, Cl), salts (HCO3, SO4, NO3, PO4), heavy metals (Fe, Cu, Pb, Mn, Co). WQI scores calculated all sites. Results: In terms standards, Site 1 had lowest TDS DO values concentration. Further, minerals salts, maximum concentrations found are given herewith: 2 (K+ NO3), 3 (Cl−, Na+), 5 (Ca, HCO3), 7 (Mg2+, PO4, SO4). pH within acceptable range, i.e., between 6 9, irrigation purposes. certain metals, specifically lead (Pb), manganese (Mn), cobalt (Co), observed be negligible. contrast, exhibited highest concentration iron (Fe) (0.0178 mg/L), while recorded copper (Cu) (0.0210 mg/L) among locations. demonstrated most favorable evaluated, whereas poorest quality. Overall, majority deemed suitable drainage irrigating crops classified under B category. However, (WQI) values, none achieved classification good or excellent quality, although at these may still utilized current first report SARS-CoV-2 samples. Conclusions: outcomes promising provide knowledgeable insights parameters, public health aspects should considered when planning WWTPs parallel reclaiming
