If there is a failure for a primary constituent <br />treatment is normally required. <br />Secondary Items listed as secondary are regulated because they may adversely affect the taste, odor or appearance of drinking <br />water. They are not directly health related. If there is a failure for a secondary constituent on a small public water <br />system it is best to consult your regulator to determine if treatment is required. A secondary constituent failure for a <br />private water system does not require treatment. However, the owner may wish to treat the water in order to <br />improve the quality. <br />Treatment If your water requires treatment we suggest that you contact a qualified water treatment company.
