Water quality was evaluated by a water quality index (WQI) based on these parameters, which are commonly used in WQI calculation. Generally, the water quality state was classified as “moderate” in LCB (mean value of 69.1). Meanwhile, the state varied obviously among the three groups, with...
No criterion for protection of human health from consumption of aquatic organisms excluding water was presented in the 1980 criteria document or in the 1986 Quality Criteria for Water. Nevertheless, sufficient information was presented in the 1980 document to allow the calculation of a criterion, even...
The WQI calculation methods have significantly enhanced water quality determination, monitoring, and evaluation in recent times. Thus, it's crucial to recognize the value these methods bring to water quality management and regulatory decisions. Numerous studies have employed the WQI to assess surface ...
Calculation of water quality index Among water quality indices, the National Sanitation Foundation Water Quality Index (NSF-WQI) is the most commonly used39,40,41. The significance of numerous parameters using this index varies based on the use of water. Therefore, the used values include the ...
The calculation and formulation of the WQI involved the following steps: 1. In the first step, each of the ten parameters has been assigned a weight (AW i ) ranging from 1 to 4 depending on the collective expert opinions taken from different previous studies. The mean values for the weig...

The other calculation is concerned with the oil-covered water, to obtain the complex dielectric constant 𝜀𝑟εr of the oil spill and oil–water mixture ratio 𝑤0w0. The long wavelength ocean waves that contribute to the surface tilt are largely unaffected by the presence of oil on the...
This study is based on hydrogeochemical and biological parameters and calculation of Water Quality Index (WQI) to assess water quality of a rural tract in five districts of Garhwal and Kumaon district of Uttarakhand, India. The drinking water quality parameters are pH, Total Hardness, Alkalinity,...
