Although sodium does not have a maximum contaminant level, the Department of Environmental Protection does have a guideline of 20 milligrams per liter (mg/L) for sensitive individuals, such as those on very salt-restricted diets.  The Acton Water District notifies the Board of Health of all sodium results, and results of the most recent sodium tests are posted at: the Acton Public Health and Nursing Service offices; the Acton Water District Information Center; the Acton Public Library; and the Acton Senior Center.  Sodium levels in drinking water vary considerably from well to well and month to month.  For the most accurate data on sodium levels at your home, an individual tap sample would be necessary.
