Comparative Analysis of Some Selected Deep and Shallow Wells In Niykangbe Community, Niger State.

Abstract

Rural dwellers depend basically on hand-dig wells or boreholes for potable water supply as the streams usually dry up in summer season. This useful resource is under threat of pollution from human life style manifested by the low level of hygiene practiced in the developing nations. Water samples were collected from shallow wells and deep wells. A total of 10 samples were collected, five each from boreholes and wells in the community over a period of three months. The samples were collected in a 1liter sterilized bottle and the physiochemical properties were carried out in the laboratory. The results showed that the minimum and maximum values recorded colour from borehole analysis was 0.00pt.Co respectively while that of well ranges between 0.00 and 416 pt.Co. The turbidity values for borehole samples showed no result while that of the well samples ranged between 3 NTU and 75 NTU. The total dissolved solid content for borehole ranged between 100 mg/L and 160 mg/L while that of well samples ranged between 90 mg/L and 200mg/L. The maximum nitrite content in drinking water should not exceed 0.2 mg/l. Nitrite values in the borehole water samples ranged between 0.03 mg/L and 0.08 mg/L, while that of the well water samples ranged between 0.00 mg/L and 0.10 mg/L. The sulphate values for boreholes ranged between 1.2 mg/L and 4.2 mg/L while that of wells ranged between 2.3 mg/L and 9.4 mg/L. It was concluded that the values obtained from the well and borehole were within the recommended values of NSDWQ (2007).
