Environmental Health Dep Description : WellHead <br />Drinking Water Interpretation <br />MCL: The maximum level at which a constituent may be present and be considered <br />acceptable for potability or aesthetics. <br />Primary: Items listed as primary are regulated because of health concerns. If there is a <br />failure for a primary constituent treatment is normally required. <br />Secondary: Items listed as secondary are regulated because they may adversely affect the <br />taste, odor or appearance of drinking water. They are not directly health related. <br />If there is a failure for a secondary constituent on a small public water system it is <br />best to consult your regulator to determine if treatment is required. A secondary <br />constituent failure for a private water system does not require treatment. <br />However, the owner may wish to treat the water in order to improve the quality. <br />Treatment: If your water requires treatment we suggest that you contact a qualified water <br />treatment company. They are normally listed in the yellow pages under the <br />following topics: <br />Water Purification & Filtration Equipment <br />Water Softening & Conditioning Equipment <br />Water Treatment Equipment <br />Health Effects Language <br />Nitrate <br />Infants below the age of six months who drink water containing nitrate in excess of the MCL may quickly <br />become seriously ill and, if untreated, may die because high nitrate levels can interfere with the capacity of <br />the infant's blood to carry oxygen. Symptoms include shortness of breath and blueness of the skin. High <br />nitrate levels may also affect the oxygen -carrying ability of the blood of Pregnant women. <br />Nitrate + <br />Infants below the age of six months who drink water containing nitrate in excess of the MCL may quickly <br />Nitrite as N <br />become seriously ill and, if untreated, may die because high nitrate levels can interfere with the capacity of <br />the infant's blood to carry oxygen.
