Dear Dr. Sudhir Sir,

For the calculation of Ground Water Quality Index, specially to indicate a particular pollution parameter please download the attached file.

Dr. Sudhir Kr Srivastava,

The changes in the quality of groundwater have allowed various studies to be carried out on the atypical behavior of the incorporation of toxic substances by the effect of discharges of wastewater, such as munipals and industrial water, without prior treatment. So the amount of major ions is decreasing and trace and secondary elements are incorporated in significant concentrations, so that the indices currently established do not reflect these important changes, and it is difficult to recommend one specifically, indices as such complement each other.

Sudhir... The examples of parameters given, Fluoride, Nitrate, Arsenic,Iron or any other parameter, need several methods of analysis. You need to refer to the standard method books (Mostly the WHO) publications on water analysis to select the right method for each parameters. Once you establish the reliable results you may follow some correlation (statistical) correlations to have the detailed map of the water quality.... Good luck.

Please consult the standard procedures for each. However, some digital meters may help.

Dear Dr Ruth and Dr Barbooti... Sir my concern is not the method of analysis for the parameters given as example, it seems I couldn't explain it properly as my question was related to the methodology related to Ground Water Quality Index and I wanted to know that how these( Fluoride, Nitrate, Arsenic etc ) parameters (if high) can be established with the help of GWQ Index.

I object the inclusion of essential to llife elements as Zn in a formulae together with well known contaminants. It may give false results in the true value of the cleaningres of the river or source. I have seen it inpractice. Authorities say a certain river was "clean" according to the equation used ( includingZn) but you can see or smell the impuirities.

Fluoride content, Coliform and toxic heavy metals are imp parameters, but for coastal waters, salinity has to be monitored
