IntroductionClean drinking water is essential as we

need to consume at least 2 litres ofwater daily for basic survival.

As the human population andadvancement in modern technology

growth exponentially, the risks for watercontamination increases.

Limited supply for us to get the cleandrinking water supply. Decided to do asurvey on contamination of drinkingwater to study the sources of drinkingwater and the level of contamination.

Problem Statement:An adequate supply of safe drinking water is oneof the major prerequisites for a healthy life, butconsumers even did not realise that the sourcesof their drinking water have been contaminatedby different contaminants.

Objectives:

- To gain knowledge, study and provide solutionstothe contaminations of water supply.

- To create awareness towards importance ofclean drinking water supply among universitystudents.

Treating Drinking Water

Quality of water and human health

Type of treatment depends on :

1. Quality of the original source of water

2. The number of people to whom the water

will be served

3. The point of origin for the water
