This study examines iron level in groundwater from boreholes and their spatial distribution
across rural communities of Benue State. Water samples were collected from 26 boreholes and
analyesd for iron concentrations as it affect the quality of drinking water as prescribed by WHO
standards. The analyses were done according to standard method of water examination. The
results of analyses show 35% of the boreholes have high iron concentrations above WHO guide
limit for drinking water. The concentration level was also found to vary spatially across the
study area. The iron concentrations in the boreholes ranged between 0.03-2.38mg/l with a
mean and coefficient of variation of 0.82mg/l, CV81.71% respectively. The presence of iron in
rural groundwater in study area may be traced to the local environment of the boreholes.These
include the geology, dissolution of iron minerals from rock and soil, precipitation/run off and
infiltration activities, use of galvanized materials in handpump construction and agricultural
landuse activities. Although iron concentrations at objectionable level were noted in some of
the boreholes villagers were found using them for drinking in the absence of any other
alternative.Some form of treatment like filtering and or Reverse Osmosis if can be afforded may
be required to reduce the risk to health over time. The study has demonstrated the need for
groundwater quality monitoring and management in the rural areas to ensure the safety of
water being provided.
