Abstract :
A significant contributor to water
contamination is acid mine drainage (AMD). In this
study, the chemical composition of water samples in the
coal mines at Odagbo, was assessed to determine the
chemistry of the mine waters and potential for acid mine
drainage (AMD). The water samples were all subjected
to thorough geochemical investigation. The findings
showed that all water samples taken in the mining area
had relatively low PH values (range from 3.24 to 3.84) in
aqueous solutions which shows high acidity value
ranging from 150 to 1730 typical of AMD, with rising
levels of TDS and SO4
2-
. Electrical conductivity (EC)
measurements showed a moderately significant range of
123.0 to 170.3 μS cm−1
. It was evident that the water
samples were SO4
2-
enriched, with values ranging from
249.50 to 1703.04 mgL-1 which indicates pollution of
mine waters. Elevated Ca2+, Mg2+, and Fe were another
characteristic of the AMD samples. As a result, the
current case study will provide an updated scientific
foundation for the detection of heavy metal
contamination's source as well as suggest critical lines of
inquiry for future research.
