PYHSICO - CHEMICAL AND BACTERIOLOGICAL ANALYSIS OF GROUNDWATER IN KATAEREGI AND ENVIRONS KATCHA AND BOSSO L.G.As OF NIGER STATE

Abstract

The physico - chemical and bacteriological parameters of the groundwater from ten locations at Kataeregi and its environs in Katcha and Bosso Local Government Areas of Niger state were determined using standard analytical methods. Results obtained showed that all the parameters are below the recommended permissible value by World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ). The bacteriological analysis for locations 1, 3, 5, 6, 7, 8 and 10 shows values higher than the permissible recommended value of WHO and NSDWQ except for locations 2, 4, 6 and 9 recorded zero E.coli. Three main water types were identified namely: sulphatic water type of the normal earth alkaline water which is most dominant, So4 type of the earth alkaline with higher alkaline proportion, and predominantly HCO3+ So4 type also of the normal earth alkaline water. Thin section analysis shows that the basement rock in part of the are is granite
