Module 4 : Water Pollution

Lecture 1 : Possible reasons of ground and subsurface water contamination

How do we measure water quality

Dissolved Oxygen: BOD Biological Oxygen Demand…the amount of oxygen consumed by aquatic decomposers

Chemical Analysis: looking for presence of inorganic or organic chemicals

Suspended Sediment water clarity

 

 

 

Indicator Species: organisms that give an idea of the health of the water body.

•Mussels, oysters and clams filter water
