There are many sources of underground water in the Middle Benue Trough, which have varying composition and constituents. Water samples from saline springs, boreholes, hand-dug wells and rivers / streams from the Middle Benue Trough are collected and analysed for cations, anions and heavy metals, using atomic absorption spectrometry (AAS); with aim of determining the concentration of the cations and anions in relation to their suitability within the tolerance limit. The analytical results revealed that the major cations such as Copper (Cu), Sodium (Na), Potassium (K), Iron (Fe) and Magnesium (Mg) have their concentrations within World Health Organization (WHO) drinking water permissible limits. However, Lead (Pb), Arsenic (As), Selenium (Se), Zinc (Zn) and Manganese (Mn) had concentration above the WHO standard and the Standard Organisation of Nigeria (SON) limits. These high values are mostly associated with the Baryte and Lead-Zinc mineralisation associated with either Keana or Awgu formations in the Middle Benue Trough and the saline brine origin of some few aquifers. This situation could potentially have a negative impact on the available water resources in the area with high risk for human consumption, although suitable for agricultural purposes. It is highly recommended that the water quality in this area is monitored from time to time and water borne diseases be systematically and promptly handled.
