ater is an essential natural resource for sustainability of life on earth. Water is a naturally occurring substance needed for activities such as industrial and agricultural processes, cooking, drinking, waste disposal and human recreation (Izonfus and Bariweni, 2001). Man cannot live without water which fills the body fluids lost through normal physiological activities such as respiration, perspiration, urination, etc (Murray et al., 2003). Drinking water is got from two main sources, surface water (streams, springs, rivers, lakes, etc) and groundwater (borehole water and well water) (McMurray and Fay, 2004). Lotic ecosystems such as streams play vital role in water cycle, groundwater W ABSTRACT Due to introduction of pollutants in surface drinking water bodies, man has been exposed to several health problems. As a result, the study investigates the status of water quality parameters and trace metal contents of the streams in Nise. The study on the water quality and trace metal contents of Iyiocha Stream and Obizi Stream in Nise, Awka South Local Government Area, Anambra State, Nigeria was conducted from April to July, 2017. Surface drinking water were taken fortnightly from the streams with standard procedures. The samples were conveyed to the Biological Science laboratory, Chuwkuemeka Odumegwu Ojukwu University, Uli where they were analyzed for pH, turbidity, total hardness, alkalinity, biochemical oxygen demand and presence of trace metals such as lead, copper, manganese, zinc and sodium. Results obtained from the analysis showed that the highest hardness mean value of 236.00 ± 14.00 mg/l was recorded in May in Iyiocha Stream. Hardness values recorded across the study months in Iyiocha and Obizi Streams exceeded the WHO standard limits. The pH of Obizi Stream was slightly acidic with an average pH value of 6.20 mg/l. The pH values for Iyiocha Stream (6.68 ± 0.22) is within the WHO permissible limits. Turbidity of both Streams corresponds with the WHO acceptable limits. The value for lead in both streams exceeded the WHO permissible limits. Similarly, the mean value for sodium concentration in the streams was above the WHO acceptable limits. The present study showed that there was no significant difference (P>0.05) between water samples from Obizi and Iyiocha Streams using unpaired student’s t-test. Monitoring of quality and quantity of streams is needed for good quality water supply to the public. Original Research Article
