What parameters/indicators are commonly used to assess the effectiveness of water treatment systems?
W01 Water Quality Indicators
total coliforms and turbidity
What is coliform?
W01 Water Quality Indicators

What is turbidity?
W01 Water Quality Indicators
a measure of water cloudiness, which may indicate the availability of food and shelter for microbes.
