Surface water quality assessment of Skardu springs using Water Quality Index
Environmental Science and Pollution Research, 2021Natural springs which originate from hilly areas of Skardu in Pakistan make their route downward and are utilized by the public as they passes from residential areas. Due to weathering processes in mountainous regions, these springs can be the source of various trace elements and pollutants.

A water quality index based on physical, chemical, and biological parameters is proposed. The index is based on a geometric mean of transformed values of the parameters with a range of zero to one. The parameters of concern are temperature, nutrients, suspended solids, turbidity, coliform bacteria, dissolved oxygen, color, pH, grease, odor, and ...

Stochastic water quality index
Environmental Technology Letters, 1982Abstract A Stochastic Water Quality Index (SWQI) is proposed and its use in assessing water quality in the Linggi River in Malaysia is shown. The SWQI provides for the first time an approach for developing an index which incorporates the probabilistic water quality entities.

A Water Quality Economic Index
Water Quality Research Journal, 1974Abstract A methodology is presented for producing a water quality economic index which will provide information on the direction and the amount of change in water quality on a regional and a national basis. It will be useful for evaluation of water quality trends and for economic decision making regarding preventive measures and ...

Water Quality Indexing and Scoring
Journal of the Environmental Engineering Division, 1980The desirability of developing water quality indices, which has been frequently cited, is examined. The development of currently available indexes are reviewed and a distinction is made between the indexing and scoring of water quality samples. It is pointed out that many indexes are, in fact, scoring methods, and that the mathematical basis for the ...

Water Quality Index and Status
2011This chapter includes a methodology for determining the water quality status of a river. The water quality of the Yamuna River is described using indirect and direct methods. The indirect method is based on various water quality indices (WQI), whereas the direct method uses water quality data at various locations on the river.
