How Is Water Impurity Assessed?

Water impurity is generally assessed by measuring physical, chemical, and biological parameters. Physical parameters include factors such as temperature, turbidity, color and odor. Chemical parameters involve measuring the concentrations of various elements and compounds including lead, mercury, arsenic, nitrates, sulfates and phosphates. Biological testing involves analyzing for bacterial contaminants such as E. coli, fecal coliform, and enterococci.

Once these measurements have been taken, they are compared to established water quality standards in order to determine whether or not the water is safe for human consumption and other uses. For example, the US Environmental Protection Agency has set Maximum Contaminant Levels (MCLs) for more than 90 contaminants, including many of the ones listed above. If a water sample exceeds one or more of these MCLs, it is considered to be unsafe for drinking. Additionally, local and state authorities may have their own limits set on certain pollutants that are stricter than the EPA’s standards.

In addition to being tested for safety, water impurity can also be assessed for aesthetic purposes. For instance, many people find high levels of turbidity or color in their drinking water to be unacceptable and so it is important to measure these parameters as well.

Overall, assessing the impurity of water involves measuring a wide variety of physical, chemical, and biological parameters and comparing them to established standards. This allows us to determine whether or not the water is safe for human consumption and other uses, as well as assess its aesthetic properties.
