Abstract

The study examined well water quality (chemical) in Jos metropolis which it collected a total of twenty water samples that were taken for laboratory analysis. The stratified systematic random method was used in the selection of sample area/location. A total of (10) out of the existing (20) wards were systematically selected, while in each of the wards, two wells with one each from higher and lower elevations were randomly selected in which water samples were collected. The samples collected were analyses at UNICEF (WATSAN) Laboratory Bauchi. USEPA method of water analysis was used to test for the chemical parameters. Pearson product moment correlation co-efficient was used test for the relationship between high and low elevation in the sample elements, as well as mean and standard deviation. The results indicates that pH, E.C, TDS, Pb, As and Cyanide appears within NSDWQMPL, while $NO_2, \:Cl, \:F, \:Mn, \:Mg, \:Ca, \:Cu, \:Zn, \:CaCo^3$ and $Cr$ marginally falls within acceptable standard for drinking water quality maximum permitted limit. Consequently, $NO_3,\: SO_4, \:Fe$ and $CaCo_3$ in some parts of Jos metropolis fall outside acceptable standard of NSDWQMPL. Moreover, $pH, \:E.C, \:TDS, \:Pb$, $NO_2$, $NO_3$, $Cl, \:F, \:Mn, \:Cr, \:As, \:Cu, \:Zn$, showed that there is no significant relationship within the individual elements in regards to elevation (high and low) in the study area whereas, $SO_4, \:Fe, \:Mg, \:Ca, \:CaCo^3$ and $CaCo_3$ showed that there is significant relationship in elevation (high and low) among the individual sample elements. The study concludes that well water quality through chemical assessment in Jos metropolis is not fit for drinking. It recommends sensitizations campaign on the importance of clean water, sanitation, enforcement of existing laws and more research be undertaken to cover for seasonal variation, more elements and sample size.
