Hydrochemical Assessment of Surface and Groundwater in Some Selected Communities of Borno and Yobe State

The study area comprises three communities of Ala, Daura in Borno State and Kyalari in Yobe State, North-eastern Nigeria which forms part of the Chad Basin. Twenty five (25) water samples were collected from major sources which comprises of nine (9) hand dug wells, ten (10) surface water and six (6) boreholes. The physical parameters analyzed revealed pH values ranging from 6.5 - 8.1 and electrical conductivity varies between 67 – 1050 mµ/cm. The results of the chemical parameters shows that Ca 2+ ranges between 3.5 to 66.5 mg/l, while Mg 2+ varies from 4.8 to 28.2 mg/l, Na + and K + varies between 0.7 to 1241.0 mg/l and 2.0 to 112.0 mg/l respectively. HCO 3 - ranges from 77.5 mg/l to 337.0 mg/l while Cl - varies from 4.0 to 160.0 mg/l.
