Physical and Chemical Parameters in Well-Water of Selected Location within North Bank, Makurdi, Benue State

Six different samples of well waters were collected within North Bank, Makurdi. The samples collected were tested for both physicochemical parameters and heavy metal analysis in the laboratory. The physicochemical parameters include colour, taste, odour, pH, acidity, alkalinity, hardness, calcium and magnesium, while the heavy metals are as follows: manganese, nickel, lead, chromium, iron, Cadmium and zinc. Heavy metal analysis was carried out using Atomic Absorption spectroscopic (Model AA6800 Shimadzu-Automated). From the results of the analysis, temperature ranges from 28.02 to 29.66oC, pH 5.9 to 6.92mg/L, acidity ranges from 34.7 to 48.7 mg/L, total alkalinity ranges from 41.8 to 19.01 mg/L, total hardness ranges from 112 to 155 mg/L, calcium ranges from 29.62 to 61.14 mg/L, magnesium hardness ranges from 60.2 to 74.2L, however the mean concentration of the heavy metal are as follows (Mn 0.25; Ni 0.023; Fe 0.46; Pb 0.09; Cr 0.03; Cd-0.30; Cu 1.67; Zn 1.79). The results of the analysis generally revealed that all the samples fall within the acceptable standard for drinking water by World Health Organization (WHO) and Standard Organization of Nigeria
