A major population of Udi and Ezeagu communities residing along river Ajali is peasant farmers who engage in the cultivation of vegetables along the river banks during the dry seasons. The existence of beverage industries around the 9th Mile Corner Ngwo of Enugu State has caused both communities to suffer from a shortage of quality drinking water, due to the constant discharge of wastewater by these industries into the Ajali River, which flows through these communities. Ajali River water near some beverage industries was then assessed for irrigation application. Water samples were collected from different locations along the river. Physicochemical and ionic parameters were analyzed using standard methods. Irrigation water criteria were applied, and the result showed that the major cation and anions were Mg²⁺, Ca²⁺, Na⁺, K⁺ and HCO₃⁻, SO₄²⁻, \({\text{PO}}_{4}^{3- }\), NO₃⁻, Cl⁻, CO₃^{− .} Na⁺ was dominant with 43% average contribution of all the cations, while the least was Mg²⁺ with 4% average contribution; HCO₃⁻ was the dominant anion with 31% contribution while \({\text{PO}}_{4}^{3- }\) was the least with 2% average contribution. The trend of the cations was Na⁺ > K⁺ > Ca²⁺ > Mg²⁺ while the anions were HCO₃⁻ > SO₄²⁻ > Cl⁻ > NO₃⁻ > CO₃⁻ > PO₄³⁻. The cation concentrations were within FAO irrigation water specifications. However, some samples recorded higher values of carbonate above FAO limit (0–3 mg/L). All the irrigation assessment criteria suggested that Ajali River water is suitable for irrigation purposes.

居住在阿贾里河沿岸的Udi和Ezeagu社区的主要人口是农民，他们在旱季期间沿河两岸种植蔬菜。Enugu州Ngwo的第9英里拐角附近存在饮料行业，这两个社区都因缺乏优质饮用水而遭受苦难，原因是这些行业不断将废水排入流经这些社区的Ajali河。然后评估了一些饮料行业附近的阿贾里河水的灌溉应用。从沿河的不同地点收集了水样。使用标准方法分析理化和离子参数。应用灌溉水标准，结果表明主要阳离子和阴离子为Mg ²⁺，Ca 2 ⁺，Na ⁺，K ⁺和HCO ₃ ⁻，SO ₄ ²⁻，\（{\ text {PO}} _ {4} ^ {3-} \），NO ₃ ⁻，Cl ⁻，CO ₃ ^-。Na ⁺占主导地位，所有阳离子的平均贡献率为43％，而Mg ²⁺最少，平均贡献率为4％。HCO ₃ ^-是主要阴离子与31％的贡献而\（{\文本{PO}} _ {4} ^ {3-} \）是至少用2％的平均贡献。阳离子的趋势为Na ⁺ > K ⁺ > Ca ²⁺>镁²⁺而阴离子是HCO ₃ ^-  > SO ₄ ^2-  >氯^-  > NO ₃ ^-  > CO ₃ ^-  > PO ₄ ^3-。阳离子浓度在粮农组织灌溉水规格范围内。但是，一些样品记录的碳酸盐值高于粮农组织的限值（0–3 mg / L）。所有灌溉评估标准均表明，阿贾里河水适合灌溉。
