Evaluation of Water Resources Qualities for Agriculture Irrigation in Abu Madi Area, Northern Middle Nile Delta

Twenty-six samples were collected from the shallow and the deep groundwater and surface water (agricultural drains and irrigation canal) to evaluate the water quality in Abu Madi area, middle Nile Delta. Irrigation water quality parameters were classified into individual parameters and integrated parameters. Salinity, sodium chloride MH, RSC, pH, and alkalinity hazards are considered as individual parameters. The integrated parameters include Welcox’s classification, US Salinity Laboratory Staff classifications, and irrigation water quality (IQW) index. Twelve samples of the deep groundwater, two samples of the shallow groundwater, and two samples of the surface water have salinity hazards. Regarding sodium hazards, Na%, SAR, and Kelley’s index calculated values mostly showed hazardous effect; however, RSC and PI values did not show hazardous effect. All the collected water samples except sample 2 have undesirable chloride concentrations (<200 mg/l) and are mostly characterized by cation–anion exchange reaction. Most of the collected samples have unsuitable MH values, corrosive CR values, alkaline pH values, and slight to moderate carbonate alkalinity hazards. The collected water samples are mostly situated in IQW moderate suitability range for irrigation and very satisfactory to satisfactory for all classes of livestock and poultry.
