Dynamics of Water Quality: Impact Assessment Process for Water Resource Management

Abstract

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.

Sustainable Wastewater Treatment and Utilization: A Conceptual Innovative Recycling Solution System for Water Resource Recovery

“…If enough clean water and a hygienic environment are available for everyone, five million mortalities caused by diarrhea can decrease [31]. This study has been designed for the solution of the problem identified in previous researches [29]. With the growing problems, there is no improvement in domestic water resources because of the increasing lack of water and decrement in water quality.…”

“…The samples of wastewater mixed irrigation water were analyzed for various physio-chemical parameters. Samples were analyzed and calculated to determine the overall quality of the irrigation water following the pattern of previous studies [29]. Table 3 shows the parameters and the method/instruments required for the analysis of water quality.…”

Treatment of Saline Water Using Electrocoagulation with Combined Electrical Connection of Electrodes

“…Water treatment is essential in ensuring access to a clean water supply [65][66][67][68][69][70][71][72]. The present study evaluated the applicability of the EC method in the removal of salts (TDS, CL, Br and SO 4 2− ) from aqueous environments using aluminum electrodes.…”

Evaluation of shallow groundwater suitability for irrigation purposes: A case study from Doornfontein area, South Africa

“…4) was further applied to rate irrigation water suitability based on the relationship between %Na and EC as high levels of any is harmful to plants. The Wilcox (1955) plot categorise irrigation water into excellent to good (class I), good to permissible (class II), permissible to doubtful (class III); doubtful to unsuitable (class IV) and unsuitable (class V) (Bhatti et al, 2019). In this study, the plot shows that both %Na and EC low values and fall within the "excellent to good" category hence the groundwater quality in the study area with regards to %Na and EC is suitable for irrigation (Fig.…”
