4. Water Quality Parameters - part B
The chapter discusses water quality parameters, focusing on classifications of pollutants and their impacts on environmental health. It highlights the importance of Total Dissolved Solids (TDS) and Total Suspended Solids (TSS), along with Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) as metrics for assessing water quality. The implications of organic loads from both natural and anthropogenic sources on water systems are also explored.

What we have learnt
- Water quality is critically assessed using parameters like TDS, TSS, BOD, and COD.
- Understanding the organic and inorganic components of water is essential for effective water management.
- Standards for water quality are evolving based on continuous research and emerging pollutants.
Key Concepts
- -- Total Dissolved Solids (TDS)
- A measure of all organic and inorganic substances dissolved in water.
- -- Biochemical Oxygen Demand (BOD)
- A measure of the amount of oxygen required by microorganisms to decompose organic matter in water.
- -- Chemical Oxygen Demand (COD)
- A measure of the total quantity of oxygen required to oxidize all organic material in the sample.
- -- Natural Organic Matter (NOM)
- Organic matter that is derived from the decomposition of plant and animal materials.
- -- Colloids
- Particles in water that are small enough to remain suspended and not settle.
