The document provides an overview of turbidity, which indicates water quality and is measured in nephelometric turbidity units (ntu). It also explains chemical oxygen demand (COD) and biochemical oxygen demand (BOD) as metrics for assessing water quality in terms of chemical and organic material oxidation. Links to practical lab experiments for determining turbidity, COD, and BOD are included.

- 2. Turbidity • Turbidity is the amount of cloudiness in the water. • It is an indicator of water quality. • Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit.

- 4. COD & BOD COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized. BOD or Biochemical Oxygen Demand is supposed to measure the amount of food (or organic carbons) that bacteria can oxidize.
