These "unregulated contaminants" are assessed using state standards known as health risk limits to deter- mine if they pose a threat to human health. If unac- ceptable Levels of an unregulated contaminant are found, the response is the same as if MCL has been exceeded; lhe water system must inform ils cus- tomers and take other corrective actions.
