Its not only bacteria that we test the water for
As outlined previously, while bacteria are one of the main things we test for it is not the only thing. Legionella, E – Coli and Coliforms are the most common bacteria samples carried out, we also test for pseudomonas among others. We also test for;
Chemicals are tested in water to determine if they are present and, if so, are they within acceptable limits. Chemical parameters that are present in drinking water can be caused by chemicals dissolving into water from pipes, chemicals carrying over from the treatment process, chemical reactions occurring between different materials in the water, or even runoff from the environment.
Metals occur naturally in the environment, where some metals are essential for life others, such as Lead and Mercury, are not essential and can have negative effects on health. Copper is an example of a metal that is essential in your diet but is toxic at high concentrations.
This parameter grouping includes all other tests not including Bacteria & Protozoa, Chemicals, and Metals. Testing for these parameters is required to signal if there is a potential problem with the water supply that requires investigation or that may point to a more serious problem.
