WATER QUALITY PARAMETERS ENTROPY ESTIMATION

Abstract

Water is among the inexhaustible resources but due to the admissible of chemical effluents in large quantities by dumping
waste, sewage wastes, and industries discharge into the rivers; contamination of water in some other ways; uncontrollable
biological activities; the weather conditions; havoc created by the humans, the quality of water become deteriorating day
by day and also from the renewable resources it came to the verge of exhaustible resources. In the present scenario, there is
a desideratum to control these particulates which directly or indirectly affect the quality of the water, and also there is a
need to stop the overutilization of these precious resources and to deal with the amalgam of the biggest problem of the
society i.e., to maintain water quality and quantity with the Multi-Criteria Decision Analysis (MCDA) to provide us a clear
view of the parameters which impact the quality. Different parameters like Dissolved Oxygen, pH, Nitrate, and Feacal
Coliform of water quality of river Yamuna at different locations are studied using the Entropy method which is used to
find the objective weights of the criteria i.e., particulates here. This study majorly reveals the parametric estimations of
water quality parameters to find the weightage of the parameters using the Entropy Method of MCDA so that government
can take advanced and immediate steps concerning the parameters and also pose strict legal actions against those who are
responsible for this major havoc.
