Experimental Investigation Of Temeke Groundwater Quality, Accessibility And Its Health Implications
Index Terms: Groundwater; Nutrient Content; Heavy Metals; Organic Pollution; Temeke; Water Quality Index
Abstract: Anthropogenic activities had significantly distressed the availability and accessibility of reliable domestic water with sufficient quality. Yet available improved sources are scarce living city slums and urban peripherals dependents of groundwater. The role played by anthropogenic activities upon nutrients, heavy metals and organic content of groundwater was the focus in order to establish the existing water quality and its health implications. Experimental investigation revealed that overall amount of nitrate was higher, 3.361 ppm than ammonia, 0.20 ppm and nitrite, 0.0697 ppm. While 0.541 ppm being the highest recorded amount of phosphorus, 53.64 ppm was the highest amount of COD recorded. Fair amount of heavy metals including Zn, Cr, Cd and Cu observed to range between 0 to within acceptable limits, however the amount of lead from residential deep well, 0.0369 ppm was above WHO guideline. Waterborne cases like diarrhoea increased annually from 2007 to 2010 whereby cholera cases were irregularly fluctuating. Computation of Water Quality Index revealed that observed water quality rarely departed from natural levels.
