Physicochemical Analysis of Groundwater in the Vicinity of an Industrial Area: a Case Study of Mopin Community, Ota, South-Western Nigeria

Abstract (2. Language): 
The physicochemical characteristics of groundwater in Mopin Community, Ota in South-western Nigeria were assessed to ascertain the quality and possible effects of the effluents from neighbouring Industrial Estate. This analysis was important because the contamination or pollution of a water source especially used for domestic and drinking purposes will be detrimental to the health of the consumers of such water. Measures of gross organic pollution; BOD, COD, TDS amongst others were determined. Four groundwater samples were collected within the months of October, 2010 to June, 2011 from hand dug wells in residential buildings that are in proximal locations to the industrial effluents discharge point and flow path and analysed in triplicates. Heavy metal levels were also analysed using AAS machine after sample digestion. It was observed that the effluents has little or no impact on the groundwater quality as indicated by the average COD value recorded which was lower than the average COD levels of the effluents.
