A comparative review on Malaysia's water quality index model with international water quality index models for surface water quality classification.

Water Quality Index (WQI) is a grading and classification system. It is used to quantify the overall water quality status of a water resource for a given location and time. This paper aims at comparing the advantages and the limitations across several different types of WQI models (CCMEWQI, NSFWQI,...
