Abstract :Quality assessment of direct harvested rainwater at Nekede landfill in Owerri west Local Government, Imo State, Nigeria was examined. Some physicochemical and bacteriological parameters were analyzed. The WHO insert ignore into journalissuearticles values(2006); domestic, irrigation and rules for consumption standards was used to assess if the harvested rainwater is impure or infected. The water samples were collected from four sampling locations at a distance of 20m away from each other. EP samples insert ignore into journalissuearticles values(March-April 2019); shows, turbidity ranged 5.0-5.20 NTU, Cl insert ignore into journalissuearticles values(3.40-3.90);, Mn insert ignore into journalissuearticles values(0.05-0.09);, NO3-N insert ignore into journalissuearticles values(8.40-9.90);, PO43- insert ignore into journalissuearticles values(0.03-0.05); mg l-1 falls within the limit, Cu 1.0-1.10 mg l-1, Zn 3.00-3.10 mg l-1 falls within WHO standards only. Cd, Al and Co2 were above the standards, SAR and Na was Not detected insert ignore into journalissuearticles values(ND);. PP insert ignore into journalissuearticles values(June – July 2019); shows turbidity, Cu, Cl, Mn, Ca, NO3-N, Na, and PO43- falls within the recommended standards. Cd insert ignore into journalissuearticles values(0.02);, Al insert ignore into journalissuearticles values(0.02-0.06);, CO2 insert ignore into journalissuearticles values(5.00-5.10); mg l-1 was above the standards, while SAR and Zn has insert ignore into journalissuearticles values(4.63-47.27); insert ignore into journalissuearticles values(3.00-3.20); mg l-1 falls within WHO standard and Mg insert ignore into journalissuearticles values(0.43-0.60); mg l-1 falls within FAO. E-Coli results on EP 20-32, PP 10-35 and Coliform count EP insert ignore into journalissuearticles values(ND);, peak precipitation insert ignore into journalissuearticles values(1-10); falls within FAO standards, Salmonella EP and PP was above WHO and FAO standards. The bacteriological parameters indicates that the water is not fit for drinking, thus the water has been seriously contaminated with dangerous pollutants.
