How can you tell if water has bacteria in it?
Bacterial contamination cannot be detected by sight, smell or taste. The only way to know if a water supply contains bacteria is to have it tested. The Environmental Protection Agency (EPA) requires that all public water suppliers regularly test for coliform bacteria and deliver water that meets the EPA standards.
What is the natural source of water?
Rain water Rainwater is the purest source of natural water. Rainwater is directly produced from water condensation in the presence of the sun. The water in lakes, rivers, and seas evaporates. During the vaporization process, all impurities are removed, and the water falls directly into the earth as rain.
Which are the two most common metals that can contaminate drinking water supplies?
The most common heavy metal pollutants are arsenic, cadmium, chromium, copper, nickel, lead and mercury. There are different types of sources of pollutants: point sources (localized pollution), where pollutants come from single, identifiable sources.
Can water make you sick?
