Water Quality Index (WQI)
Water Quality Index
The Water Quality Index is a numerical expression that describes the quality of water based on various physical, chemical, and biological parameters. It provides a simple and effective way to summarize complex water quality data into a single value or score.
Parameters
1. pH: Measure of acidity or alkalinity.
2. Temperature: Affects aquatic life and chemical reactions.
3. Turbidity: Measure of water clarity.
4. Dissolved Oxygen (DO): Essential for aquatic life.
5. Biochemical Oxygen Demand (BOD): Measure of organic pollution.
6. Nutrient levels: Nitrogen and phosphorus levels.
7. Bacterial contamination: Presence of pathogens.
Applications
1. Water Resource Management: WQI helps identify areas requiring improvement and prioritize management efforts.
2. Water Treatment: WQI informs treatment processes and ensures safe drinking water.
3. Environmental Monitoring: WQI tracks changes in water quality over time and assesses the effectiveness of conservation efforts.
4. Public Health: WQI helps protect public health by identifying potential waterborne health risks.
