Summary Introduction

To determine:

Ways to detect the water quality of river.

Introduction:

The mussels are the aquatic organisms that can form colonies in the water. They are bivalves. They are filter feeders and feed on algae and other smaller sedimented organism in water.

The water quality index (WQI) is the parameter used for checking the quality of water. It involves measurement of temperature, pH, solids and sediments in dissolved form, turbidity, dissolved oxygen, and hardness.

WQI range and water type:

< 50 - Excellent water.

50 − 100 - Good water.

100 − 200 - Poor water.

200 − 300 - Very poor water;

> 300- Water unsuitable for drinking.
