Abstract
Fractured crystalline rocks and the overlying
overburden, which is derived mainly from the insitu
decomposition of the former, are the two types of
geologic environment in which groundwater occur in Bauchi
area. The overburden is the most important and its
thickness varies from 0 to about 75 meters.
Groundwater table elevation ranges from less than
533 to about 655 meters above sea level.
Transitiveness of the overburden vary from place
to place and range from about 1.03 x 105 to 1,6 x 10-4
m/s. Estimates of the readabilities of the overburden
also vary and range from about 214+ x 10-7 to 5.86 x 10-6
m/s. Yields of boreholes vary greatly from 1.4+ to 29.50
m3/h, specific capacities of boreholes lie between 0.06
to 2.32 m3/h/m with a mean of 0.65 m3 /h/m.
Principal ions in the water are calcium and
bicarbonate. The water is generally hard; it is suitable
in chemical quantity for drinking, irrigation and some
industrial purposes. Feces from pit latrines and septic
tanks placed below ground surface are the main sources
of groundwater contamination
