The results of tests, from samples of water, can be misleading. There are many reasons why water samples may not be truly representative of water quality or purity.
Traces of hundreds or even thousands of organic or inorganic substances can in present in any given sample of water. Any two samples taken from the same location on the same day can vary in an analysis, when looking for a wide spectrum of components.
The timing and location of the test sample is critical as water quality often changes seasonally and after heavy precipitation events.
Even if water tests show that there are not direct bacteriological risks in the sample. The water could have chemical contaminants not tested for in the sample. The water can also become contaminated after the test location in pipes tanks or from cross- contamination.
