Authorities use drinking water tests to strictly control our water, but heavy metals such as lead, chromium, or zinc can also be released from old water pipes, and drug residues are difficult to filter through water treatment plants. It is important to measure water hardness with a water hardness test because excessively hard water is harmful to dishwashers and washing machines and can be damaging to skin and hair. The drinking water tester can also be used as a well water test, as well water is extracted from the ground and therefore has not been tested by the authorities.
