摘要：

The quality of groundwater for irrigation was assessed in Warri and the surrounding area using America Public Health Association standard (APHA) method of analysis. The following results were obtained from different constituents that influence the water quality for irrigation. Electrical Conductivity was found within the range 207-1163, Soluble Sodium Percentage (SSP) was found between 1.12 and 218.75, Sodium Percentage (Na%) from 2.56 to 280.00, Permeability Index (PI) was found within 0.00-5.75, Sodium Adsorption Ratio (SAR) ranges from 0.02 to 1.31, Residual Sodium Bicarbonate (RSBC) ranges from -0.17 to 0.26, Kelly's Ratio (KR) ranges from 0.02 to 133.33, Total Hardness (TH) ranges from 5.5 to 84. Comparing the above estimated result with the various permissible standard values for irrigation, SSP, Na% and Ec were found to be slightly above the standard values at some locations while all other constituents were found to satisfy the standard value for irrigation. The groundwater facies analysis plotted with Chadha revealed that the water shows little characteristics of Na+ HCO3- and Na+ + Cl- water types, while for Gibbs plot, it revealed that groundwater chemistry is controlled dominantly by rock weathering processes.
