there are so many methods of water quality indices; I want to know that does any method use physicochemical and biological parameters to represent overall water quality in a single term.
Water quality index...is very common method to evaluate water quality in river or ground water.
yes their are indices refer, D. Harper in his book on eutrophication
There is information and a useful spreadsheet available via the attached link Avinash (Water Quality Index 1.2). It takes into account most of the parameters you list and it can probably be adapted to meet your specific requirements. There are numerous other indices available.

Is there any limit to select variables for CCMEWQI, because i have worked on 14 physicochemical and 8 toxic metals. So how many and which variables are applicable in CCMEWQI?#Sir John Machell
