Comparative assessment of the physicochemical parameters and impact of waste dump site on ground water quality in ajata and gosa during wet season in fct abuja, Nigeria

Investigations were carried out to ascertain the level of trace metals and physicochemical parameters of ground water inAjata and Gosa waste dumpsites in FCT Abuja. Samples were collected during wet season from ten wells and ten boreholes each in Ajata and Gosa. Samples were taken to the laboratory and were analysed using standard methods (APHA). Result of ANOVA revealed that there was no significant difference in trace metals found in wells with respect to season and location except nitrate. (p<0.05) also, there was no significant difference in trace metals foundin boreholes with respect to season and locations (p>0.05). Physicochemical parameters of most groundwater investigated in Ajata and Gosa fall within the guidelines recommended by (WHO) and (NSDWQ) of maximum acceptable standard for drinking water except total dissolved solids. Results oftrace metals and physicochemical analysis of groundwater in some areas in Ajata and Gosa was also found to exceed guidelines standards of (WHO) and (NSDWQ)as a result of compromised sanitary conditions and leachates from dumpsites waste. This can constitute serious public health issues. Government policies on waste disposal and management should be enacted and strictly enforced to avoid gross contaminations of groundwater.
