COMPARATIVE ASSESSEMENT ON WELL AND BOREHOLE WATER QUALITY INDEX IN SOKOTO METROPOLIS

Abstract

ABSTRACT

The study focuses on the comparative assessment on the levels of some of the physiochemical parameters of well and borehole water collected from five sampling locations in Sokoto metropolis to ascertain their quality index. Samples were collected randomly and analyzed using standard method of analysis. The physiochemical parameters analyzed in this study include; pH, Turbidity, Total Dissolved Solids (TDS), Calcium (Ca²⁺), Magnesium (Mg²⁺), Chlorides (Cl^-), Fluorides (F^-) Sulphates (SO₄) and Nitrate (NO₃^-). The water quality index of these physiochemical parameters was determined using the method proposed by Horton (1965) and Brown et al. (1970) and the result shows that both water sources were found within excellent and very good water quality index respectively which indicates that both water sources (well and borehole water) consumed within Sokoto metropolis are safe and suitable for drinking as it meets the minimum requirements of WHO standard of drinking water quality.
