SUB normally presents its water quality data by referencing a maximum contaminant level (MCL), which is a regulatory threshold limit set by the EPA. Until the EPA’s April 2024 announcement of a new PFAS regulation, there was no MCL for any PFAS chemicals. SUB will be able to compare its results to the MCL at the end of 2027, when we have completed four quarterly samples in one year.
The Oregon Health Authority (OHA) is updating its rules to align with EPA’s standards. SUB will continue to work with the Oregon Health Authority to ensure that we continue to provide safe, high-quality water to our customers.
