    (U. P, 2010-06) Okereke, J. N.; Nwigwe, H. C.; Iwuala, M. O. E.
    Evaluation of groundwater quality in some parts of Imo State was done, based on analyses of N, Nq to samples from boreholes and springs. Analyses were based on American Public Health Association (APHA) guidelines. The overall average values of total heterotrophic bacteria, total; coliform counts and Escherichia coli counts were 7.2622 x 104 CFU/ml, 12.5 Cr/100m1 and 1.0 CFU/100m1 respectively. The average value of pH was 6.7 while hardness raged between 6.60mg/1 and 16.90mg/1; turbidity, 1.0mg/1-2.90mg/1; chloride, 8.96mg/1-2,1'.00mg/liron (II) ion, 2.6mg/1-3.71 mg/I, and nitrate, 4.88mg/1-6.4mg/1. Heavy metals were within the permissible limits except cadmium which recorded an overall average value of 0.1854pm. The study reveals that groundwater in Imo State, if well handled, remains a safer source Of drinking water supply to the populace
