Content:
This book covers water quality indices (WQI) in depth - it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit
Note:
pt. 1. Water quality indices based predominantly on physico-chemical characteristics -- pt. 2. Water quality indices based on bioassessment -- pt. 3. Looking back, looking ahead.
