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. 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.
