A Study on the Pollution due to Dissolved Copper and Chromium in the Water Column of Muvattupuzha River

Various methods have been used for estimating the pollution in water columns. But there exist uncertainty in the quality criteria employed and the vagueness in the input data leads to the vague output values. Fuzzy set theory has been successfully used for the analysis of vague and imprecise information. This paper presents a study on the pollution due to dissolved trace metals of Copper and Chromium in the water column of Muvattupuzha river using modified fuzzy synthetic evaluation approach.
