Analytical results of groundwater quality in Jada and environs indicated that the
order of abundance of cation concentration were Ca2+>Mg2+>K+
>Na+

. The groundwater quality is good for
human consumption based on Revelle and Contamination indices but poses health
risk due to bacteriological contamination. The Revelle and Contamination indices
ranged from 0.1 to 0.5 and -10.5 to -8.2 with mean values of 0.2 and -9.7 and
coliform number counts ranged from 1 to 12 with mean of 4, respectively. EC,
TDS and TH values indicated good quality water for irrigation practice. The
chemical Index such as SAR, RSC, and KI, % Na, PI and MR were calculated.
The results indicated that PI and MR values revealed groundwater quality that is
unsuitable for irrigation practice. PI values ranged from 24.1 to 254.3% with mean
of 93%, MR ranged from 34.3 to 82.5% with mean of 60.8%. Chloro-Alkaline
