Alaago-Alapoti area constitutes part of the Eestern Dahomey Basin of South-Western
Nigeria and it is characterized by different formations. Samples were collected from this area
and were subjected to the laboratory for test.
Nine smaples were collected from Alaago-Alapo area, five hand-dug wells and four
boreholes sampled and investigated in the persent study. This study characterises the physicchemical quality of ground water obtained from the hang-dug wells and boreholes. To get a
clean water from the boreholes and wells some physical and chemical investigation were
carried out from the wells in Alaago-Alapoti using standard methods and equipments. The
samples were analysed to determine thethe presence and concentration of cation and anions.
The results shows that the pH values range from4.28-5.59 in Alaago and 4.28-5.22 in
Alapoti which indicate slightly acidic water. The TDS range of the water samples is between
130-140mg/l in Alaago and 300-500mg/l in Alapoti, Electrical Conductivity ranges from 45-
45 uS/cm in Alaago and 36-50uS/cm,in Alapoti. The samples collected at Alapoti have a
sodium mean value of 648.6 and ranges from 864-466, while that have Alaago has a mean
value of 636.6 and ranges from 180-680 which is high compared to the WHO standard.,
Calcium in Alapoti ranges from 2-12 and has a mean value of 6 and in Alaago it ranges from
4-150, Potassium ranges from 3.8- 7.5 with mean value of 6 in Alapoti and ranges from 3.4-
9.6 with the mean value of 6.93, Magnesium in Alapoti area has a mean value of 138 and
range of 126-160 and that of Alaago have a mean of 44 and range of 0-132, Bicarbonate
range from 8-26 with the mean value of 13.3 mg/l in Alapoti while Alaago has a range of 44-
68 with a mean value of 128.6. The water is not good for human use, it is risky to human
