ABSTRACT
This study was carried out with river water of Gashu’a, water and aqueous sediment samples were collected from different points of the river and analyzed for heavy metals. A total of 16 water and 8 aqueous sediments samples were collected from 4 different locations Abattoir, bridge, behind prison and zango (Takari). All the samples were analyzed for heavy metals, such as Cu, Cd, Pb and Fe etc. using standard procedures, while nitrate and the ammonia where tested by Palin test method. The results obtained were compared with international standards. All the samples results obtained were within the recommended limits set by WHO (2010), as well as New Zealand (1000 μg/L) and US EPA (100 μg/L) maximum acceptable limits. The results of the present study have shown that river Gashua is free from heavy metals contamination. This study, therefore, recommends the government and other responsible authorities to take appropriate measures to ensure that the water is not polluted in future.
