“…Sometimes decision-making approaches are needed to assess the quality of water. Different water quality approaches such as Fuzzy logic [6], Regression Analysis [4], Weighted Athematic [3], Ordered weighted Averaging and TOPSIS [1], Multivariate Analysis [7], Spearmen's rank correlation [8] and neural networks [9] are exercised in making the decision on quality of water. But monograph-based techniques like Wilcox's [10] and Richards's [11] and Doneen's [12] approach are easy to adopt and implement for management and policy development purpose.…”

Surface water is an important source of water supply for irrigation purpose and in urban areas, sewage water is being disposed of in nearby canals without treatment. A study was conducted to investigate the dynamics of water quality of irrigation canal as a result of this practice. The study ascertained the impact of different salinity parameters, indices and approaches to examine the hazardous effects on quality of canal water. The study analyses the samples collected for various parameters like pH, TDS, EC, Na, Cl, Ca, Mg, K, CO3, HCO3 etc. It helped to decide the restriction on use of water based on FAO-UN guidelines. Investigations were focused on assessment of contaminants affecting the quality of water and having hazardous effects on different stages of irrigation water usage. Wilcox diagram and Doneen’s approach-based analysis helped to identify the class and quality of water. This study shall help to analyze the quality of water and provide support to the decision makers for better water resource management and policy development for irrigation purpose i.e. treatment and distribution of water resource.
