Assessment of the Hydrogeochemistry of the Groundwater Resources of Gwoza, Northeastern Nigeria

The study was carried out in Gwoza town of Borno Sate to assess the chemistry groundwater Local Government. Eighteen (18) samples were collected for purpose this study; analyzed their physical parameters at spot using field kits combined pH/EC/TDS/Temperature meter model Mi 806 also used measuring parameters. GPS locating sampling points. Sodium and Potassium by flame photometry method; Calcium Magnesium determined Atomic Absorption Spectrometry method AAS-400 PerkinElmer type. Iron spectrophotometer, Photometric determine sulphate while chloride analysed argentometric bicarbonate HCO3- carbonate CO3-2 From result obtained Na+ range from 26-200 mg/L, K 7 – 59 Ca+2 45- 290 Cl-2 20 264 HCO3-2 120.06 - 292 .9 NO3-2 14 670 SO4 0 79 Fe2+ 0.08 0.44 Mn+2 0.00 0.20 mg/L Mg2+ 0.45 1.95 mg/L. results analyses compared with WHO standards drinking water indicates that some locations are above permissible limit all other elements within set standard. Therefore is not safe bacteriological analysis recommended area.
