Index of Water Quality (IWQ)

The Index of Water Quality (IWQ) is a numerical assessment that evaluates the overall condition of a water body, such as a river or lake. It combines various measurements—like levels of pollutants, dissolved oxygen, pH, and nutrients—into a single score. This score helps determine whether the water is suitable for uses like drinking, recreation, or supporting aquatic life. A higher IWQ indicates better water quality, while a lower score suggests pollution or contamination. The IWQ provides a comprehensive, easy-to-understand way to monitor and compare water health over time or across different locations.
