Groundwater samples from three (3) tubewells located on Sarkin-noma fadama farm, on the bank of River Niger in the Confluence town of Lokoja were collected randomly between March and September 2011 and investigated to ascertain the quality status and suitability for irrigation. Physico-chemical properties were determined using appropriate analytical methods. The water samples were neutral with pH values ranging from 6.9 to 7.2. They had very low salinity values (ECw 250 to 385S/m). The Sodium Adsorption Ratio (SAR) ranged from 1.05 to 1.55. This indicates a low risk of sodium build up in the soils. Irrigation water of very low salinity and low SAR can lead to problems of water infiltration into the soils. Other groundwater hydrological investigations need to be done to profer suitable management advice.
