Study Notes
Water Quality Parameters
- pH indicates the level of acidity or basicity of the water, with a pH below 7 being acidic, 7 being neutral, and above 7 being basic.
- Dissolved Oxygen (DO) indicates the amount of oxygen present in the water.
Organic Matter Indicators
- TOC (Total Organic Carbon) indicates the total amount of organic matter present in the water.
- BOD (Biochemical Oxygen Demand) indicates the amount of oxygen required by microorganisms to break down organic matter in the water.
- COD (Chemical Oxygen Demand) indicates the amount of oxygen required to chemically oxidize organic matter in the water.
Nutrient Indicators
- Nitrogen and Phosphorus indicate the presence of nutrients that can support excessive algal growth, leading to eutrophication.
- N-Kj (Kjeldahl Nitrogen) indicates the total amount of nitrogen present in the water, including organic and ammonia nitrogen.
- Tot-P (Total Phosphorus) indicates the total amount of phosphorus present in the water.
Importance of Water Quality Parameters
- Measuring Dissolved Oxygen (DO) is important to ensure that aquatic life can survive in the water.
- Measuring BOD (Biochemical Oxygen Demand) is important to assess the potential for oxygen depletion in the water, which can harm aquatic life.
