SHORT TERM ANALYSIS OF QUALITY PARAMETERS OF SELECTED DEEP WELLS: A CASE STUDY OF AN AGRARIAN COMMUNITY IN BOSSO LOCAL GOVERNMENT AREA, NIGER STATE

Abstract

Pollution of groundwater at any level has been linked to industrialization and urbanization which has come to stay over time. This study seeks to establish the effect of age of dugged deep wells and contamination level in Niykangbe community of Niger State, Nigeria. Five sets of samples were collected each from the already identified deep wells for a period of five months during the dry season of the year 2015. The samples were tested for the physical, chemical and bacteriological properties include two years after preliminary study was carried out for the same study location. The results showed that the values recorded for alkalinity ranged between 22 mg/L and 73 mg/L while that of calcium ion ranged between 0.1 mg/L and 0.4 mg/L. It was also observed that for the same study location and same deep wells the values for BH1 and BH5 increased by 75% and 50%, respectively for the calcium ion content. Nitrite values in the borehole water samples ranged between 0.01 and 0.05 mg/L. It was therefore concluded that the various parameters tested for the various boreholes were within the recommended standard of Nigerian Standard for Drinking Water Quality values although some variations exist when compared with the initial study carried out.
