This project is concerned with comparative analysis and
treatment of well waters in Ebonyi state, Nigeria. The well
water samples for this analysis were obtained from the
thirteen local government areas in the state and were
analyzed for physco-chemical and microbiological
parameters such as odour, pH, electrical conductivity, total
hardness, magnesium, calcium ion, sulphate, nitrates,
chemical oxygen demand (COD), turbidity, total coliform,
Escherichia coli, faecal streptococci and plate count. The
result of the experimental analysis using Response Surface
Methodology (RSM) design called central composite
design (CCD) showed that the chemical, physical and
microbiological parameters are within the permissible
limits of the NSDWQ/WHO except for nitrates,
magnesium, turbidity, total coliform , Escherichia coli,
plate count and faecal streptococci with values of 18.30
mg/, 7.05mg/l, 6.48 NTU, 611.00 cfu/ml, 6.92cfu/100ml,
2.62, and 141.23 cfu/100ml whereas the acceptable values
by NSDWQ/WHO are 50.00/10.00mg/l, 0.20/150mg/l,
5.00NTU, 10.00/0cfu/ml, 0/0cfu/100ml, 0/0, 0/0cfu/100ml.
Also, form the results of the analysis of the well water
samples from Abakaliki, Afikpo North, Ezza south and
Izzi local government areas contain iron content as high as
400 mg/l, 440 mg/l, 400 mg/l, and 400mg/l which are
above the acceptable range of 300mg/l by NSDWQ/WHO).
Therefore, from the results obtained the standard of well
waters in Ebonyi state in terms of chemical, physical and
microbiological data parameters are well below the
required standard of NSDWQ and WHO, but can
successfully be treated by adsorption method and
annihilation of the microbes.
