Physico-Chemical and Microbiological Analysis of Borehole Water Sources in E-One Estate Lemna, Calabar, Cross River State, Nigeria

The study examined the physico-chemical and microbiological parameters of boreholes water sources in E- one estate in Lemna, Calabar municipality, Cross River State, Nigeria. Fifteen (15) boreholes were identified and geo-referenced with the help of a global positioning system (GPS). Data were further processed in ArcGIS by overlaying the location on the study area map. Water samples were collected and analyzed for water quality parameters such as dissolved oxygen (DO), potential of hydrogen (PH), biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solid (TDS), chlorite, electrical conductivity, fecal coliform, sulphate, nitrate, turbidity, manganese, color and potassium according to [10], and the data form the analysis were analyzed using t-test to determine the significance t-test difference as compared with world health organization (WHO) and the results shows that, BOD (4.741
