Abstract

The problem of shortage of water supply is athreat to inhabitants that do not have access to potable water supply. The research is aimed at determining the quality and quantity of groundwater in LAUTECH community, Ogbomoso with the mind of ascertaining the hydraulic properties of boreholes and the suitability of the water resources for domestic and agricultural purposes. Pump testing was conducted in LAUTECH to determine the actual discharge. Water samples were collected and analysed for physicochemical parameters and bacteria using Standard method.Quality Indexes such as Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP) and Residual Sodium Carbonate (RSC) were used to assess the suitability of water for agricultural purposes.The range of hydraulic properties of aquifers (Transmissivity (0.095 m2/day to 7.591 m2/day), Hydraulic conductivity (0.003 m/day  to 0.278m/day), Specific capacity (0.250 m3/ day/m to 16.506 m3/day/m) and Yield (0.341l/s -1.66l/s), shows that four (4) out of the seven (7) borehole have moderate yield which are quiet prolific. All  the water samples within the study area falls below the WHO,2004 indicating that there is no contamination and that LAUTECH groundwaters are suitable but the biochemical result showed  that LAUTECH stream  are highly polluted .The prolific boreholes which include  engineering workshop, work’s workshop, new ICT, and health center  have moderate yield and rapid recharge rate and this  contribute to minimum quantity of water supply on campus while the  less prolific ones which are those at FAG (Faculty of Agriculture), mathematics department, and senate building  have  low yield  and with very slow recharge rate .Hence it is recommended Recconnaissance survey through the use of Very Low Electromagnetic (VLF-EM) Method should be duly incorporated alongside Geophysical survey to avoid the problem of dry boreholes or seasonal well in Borehole drilling.
