HIGHLIGHTS

  • An effective strategy in conveying water information is the water quality index (WQI).
  • It focuses on WQI models, quality parameters and comparison of WQI models in five countries.
  • Selection of water quality parameters and models is based on assessment, cost effectiveness and availability of data.
  • Iraq compared to the other four countries used in the study needs more attention to improve water quality.

ABSTRACT

Water is an important resource to human health, aquatic ecosystem, socioeconomic development, and food security. Therefore, in every part of the world, the presence of contaminants in natural freshwater causes serious environmental issues. Constant monitoring of water bodies using some quality parameters is required. In this study, turbidity, dissolved oxygen (DO), nitrate, fecal coliform (FC), total solids, pH, biochemical oxygen demand (BOD), temperature and phosphate were assessed. One of the most vital and effective strategies in conveying information related to water bodies is the water quality index (WQI). WQI is primarily a mathematical means of deriving a single value which shows the water quality level in certain water basins, e.g. lake, river or stream. For different regions, many WQIs have already been introduced by national and international agencies for water quality assessment considering various uses and control of contamination. This study focuses on a comprehensive review about WQI models, water quality parameters and comparison of using WQI models in five different countries, namely, Canada, USA, Australia, Malaysia and Iraq. Comparison of water quality and index models through these five countries reveals that the application and modification of WQI models can help to improve water quality. Also the selection of water quality parameters and index models is based on assessment, cost effectiveness and availability of data. Iraq compared to the other four countries used in the study needs more attention to improve water quality.
