Abstract
Inadequate and improper management of municipal solid waste disposal sites pose serious environmental threats to their surrounding and nearby resident due to groundwater contamination, causing various health problems. This investigation was carried out to assess the groundwater contamination of well water around dumpsites in Oyo, South Western Nigeria. Fourteen water samples were collected from active wells and analyzed for physicochemical parameters. The fourteen water samples were observed to have pH values ranging from 6.57 to 7.83, with an average of 7.30 , the TDS ranges from 107 to 960 with an average of 499 mg/l and hardness ranges from 42 to 344(mg/l CaCO3. The Turbidity from 0.08 to 0.34 (FTU) with average of 0.169 (FTU). The analytical results obtained showed high level of pH, and very high level of electrical conductivity compared to World Health Organization, WHO standards of 417.00 permissible limits. Total Dissolved Solids is above the recommended value of 500 which may affect the taste adversely and deteriorate water pipes and other piping appliances. Calcium is within the recommended value of 100. Bicarbonate and Magnesium values are above the WHO standard. High value of magnesium can lead to hardness of water with frequent intake resulting to cardiovascular disease, cancer, diabetes and childhood atopic dermatitis, while high value of bicarbonate causes diarrhea, constipation in the human body and also causes a deformation in plant growth. Sodium and potassium values are within the recommended WHO permissible limits. Nitrates and sulphates are below the recommended WHO values.
