Water quality analysis, treatment, and economic feasibility of water services of the Neora River in the fringe area of Neora-Valley National Park, India

Surface water assessment is essential for an accurate water management plan. The present investigation was focused on quality analysis, treatment, and economic feasibility of the River Neora, a raw water source in the fringe area of the Neora-Valley National Park, India. Pearson's correlations showed a positive correlation (0.629) between temperature and total solids (TS), whereas a negative correlation (−0.23) for dissolved oxygen with other parameters. In ANOVA, F-value (>1) was obtained for all parameters except BOD5. The water quality index (WQI) was determined to find out whether the river water meets the drinking water requirements for local inhabitants in the lower fringe. A high coliform count (approximately 4.5/100 mL) downstream further warranted the design of an advanced treatment, the electrochemical oxidation batch reactor. To maintain the water quality grade, the estimation of water benefits was mandatory. The water consumption for domestic and non-domestic purposes was calculated at 5,314,400 and 1,470,000,000 L/yr, respectively. Obtainability and no tax coverage might have led to the overexploitation of water, which paved the way for monetary evaluation (US$695.29). This study provided an overview of the potential of River Neora, which can be restored in the long run by adopting the water development policies by the government.
