Hydrochemical Assessment of Groundwater around Lapite Dumpsite for Irrigation Water Quality in Ibadan, Southwestern Nigeria

Due to the increase in population and industrialization growth, most countries world depend on groundwater meet agriculture demands for food production. The water contamination due indiscriminate solid wastes has necessitated assessment of quality its suitability agricultural usage. Twenty four ten stream samples were randomly collected from downslope upslope side dumpsite all major physio-chemical parameters. pH indicates slightly acidic alkaline nature. High concentrations nitrate, total dissolved solids electrical conductivity suggest impact waste resource. Assessment irrigation based Sodium Adsorption Ratio (SAR), Soluble Percentage (SSP), Permeability Index (PI) Magnesium content (MC) indicated that fall within permissible standard water. Thus, should be used with caution crops long time sustainability.
