Bacteriological and physico-chemical properties of borehole water in Niger state polytechnic, zungeru campus

Bacteriological and physico-chemical analysis of borehole water from the staff school, science department and the female hostel boreholes in Niger State Polytechnic Zungeru Campus were conducted. The fecal coliform counts obtained from the female hostel boreholes was 5cfu/100ml while that of the staff school and the science department were negative. The bacteria isolated from the female hostel borehole were: E. coli Klebsiella Salmonella, and Serratia. The physico-chemical parameters determined were: Temperature with a value of 26.3° C from the science department as well as that of female hostel borehole. While the staff school borehole have a temperature of 26.4° C. Dissolved oxygen with a value of 6.24 mg/l from the staff school, 5.52mg/l from the science department bore hole and 7.21mg/l from the female hostel bore hole.Has pH value of 7.51, staff school bore hole, 7.34 science department and 7.60 from the female hostel borehole which all lies within the NIS permissible limit. Total hardness with a value of 108 staff school bore hole, 210 science department bore hole and 310 female hostel bore hole, lies within NIS permissible limit while that of the science department and the female hostel boreholes were above the permissible limit which characterize them as hard water. Iron content from the staff school bore hole was 0.07mg/l, 0.20mg/l science department bore hole and 0.27mg/l from the female hostel boreholes and all are within the NIS permissible limit. Chloride with a value of 17.70mg/l from the staff school borehole, 35.40mg/l from the science department boreholes and 44.30mg/l from the female hostel borehole and they all lie within the NIS permissible limit.
