Abstract

A water quality index (WQI) is a way to represent complex water quality data and communicate it to the general public. This paper represents an overview of the CCME WQI method. The considered method incorporates three main elements, the number of variables not meeting water quality objectives (scope), the number of times these objectives are not met (frequency), and the amount by which the objectives are not met (amplitude). As a result, a number between 0, being the worst water quality, and 100 being the best water quality, is attained that is used to describe the surface water's state. After an in depth analysis, the method is applied for the determination of the CCME WQI of Lake Ludas for the year 2012.
