Water Quality Assessment with Water Quality Indices [PDF]
International Journal of Bioresource Science, 2015 A water quality index provides a single number that expresses overall water quality at a certain location and time based on several water quality parameters. Water quality index (WQI) is valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate treatment technique to meet the

Water Markets and Water Quality [PDF]
American Journal of Agricultural Economics, 1993 AbstractIn addition to improving the allocative efficiency of water use, water markets may reduce irrigation‐related water quality problems. This potential benefit is examined with a nonlinear programming model developed to simulate agricultural decision‐making in a drainage problem area in California's San Joaquin Valley.
