ASSESSMENT OF GROUNDWATER QUALITY IN SHALLOW WELLS IN IKORODU LOCAL GOVERNMENT AREA OF LAGOS STATE, NIGERIA
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2012, Vol 1, Issue 4
Abstract
The study examined the physical, chemical and biological qualities of 15 existing shallow wells from 15 different communities in the Ikorodu Local Government Area of Lagos State. Samples were collected and analyzed following standard methods for the examination of water quality (APHA, 2005). Parameters studied include pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Turbidity, Total Hardness, Nitrate, Chloride, Sulphate, Calcium and Coliforms. Physicochemical parameters such as EC, TDS, nitrate, chloride and sulphate were within the limits set by the WHO. However, the water quality observed at Majidun shows that the concentration of calcium, total hardness and TDS were above acceptable limits. Also, e-coli were detected in samples from Majidun along with Gberigbe and Imota.
