dc.description.abstractThis study looked at the effects of solid waste dumpsites on groundwater quality of Samaru-Zaria, Kaduna State, Nigeria. Water samples were collected from twenty four (24) different wells from three (3) strategic areas that have major dumpsites in Samaru. Twelve of these samples were taken during the dry season (April) and another twelve taken during the rainy season (August) from both bore holes and hand dug wells. Of the twelve samples, six were taken within (0-50 meters) to dumpsites and another six far away (50-150 meters) from the dumpsite. In carrying out the research, physico-chemical properties of well water was tested in the laboratory, while heavy metal properties was tested for soils in the dumpsite and well water. The pollutants assessed include, Biological Oxygen Demand, Total Dissolved Solid, Dissolved Oxygen, Chemical Oxygen Demand, Chloride, Total Hardness, Colour, pH, Magnesium, Zinc, Iron, Chromium and Lead. Test-test was used to test for significant difference between parameters while Chi-square was used to test for the relationship between quality of water in wells close to and those far away from solid waste dumpsite in dry and rainy season and relationship between heavy metal concentration in the soils of dumpsites and shallow and deep well water. From the findings of the research it was discovered that many wells in the study area located close to the dumpsite (0-50 meters) have levels of concentration of pollutants of both physico- chemical and heavy metal to be high (in wells close to dumpsites) compared to wells far from dumpsites < 50m. It was also discovered that the concentration of pollutants during the wet season is higher than that during the dry season. From laboratory analysis conducted it was discovered that COD had the highest physico-chemical concentration of 648.50Mg/L and BOD a concentration of 0.20Mg/L. The heavy metal with the highest concentration is Magnesium with a concentration of 960Mg/L and the least heavy metal concentration recorded was Chromium with a value of 0.0006Mg/L. In general, it was discovered that shallow wells had a higher percentage of contamination for both close to and far away from dumpsites than the deep wells in the study area. It was also discovered that deep and shallow wells close to dumpsites have a higher total contamination rate than deep and shallow wells far from dumpsites but there was no significant difference between them as revealed by the t-test. The results obtained from the chi-square revealed that there is a significant difference between the World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ) standard for potable water and the obtained values with an implicative result that the water from Samaru shallow and deep wells is not safe for direct consumption. Thus, such water should be treated by employing some measures such as the use of disinfectants or boiling before use which will help reduce the pollutants, but majorly an improved water supply to the study area will go along way to correct the unhealthy conditions.en_US
