The results of a water quality test can rule-out or confirm water problems. Many health-related water quality issues, including the presence of arsenic (chemical symbol - As), cannot be recognized without a water test. It is important for the test to determine the level of arsenic and its chemical form (i.e., species) in order to use the right treatment/ removal process. The As(III) species is more difficult to remove or reduce than the oxidized As(V) species. Water quality information is needed to enable a treatment professional to design a system that will operate at the highest efficiency with the lowest maintenance cost while ensuring that the treatedwater is safe. Most well water systems will not need water treatment unless arsenic is detected above the United States Environmental Protection Agency's (EPA) Maximum Contaminant Level (MCL) of 10 parts per billion.
