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

Abstract

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 m 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
