Everett monitors for regulated and unregulated chemicals/compounds/substances in our drinking water that aren’t included in the EWG database. Our 2019 Water Quality Summary contains our complete report with the most recent data. Any results over the EPA’s Maximum Contaminant Level (MCL) are reported to customers in the annual water quality report.
