What has changed about the monitoring required by the EPA?
The new standards do not change the maximum contaminant level (MCL) for the byproducts. What they change is the way the water system is monitored to collect data. Before, a water provider could average readings from all checkpoints, and compliance meant keeping that average below the limit. Under the new rules, each checkpoint must remain below the limit. Additionally, the new rules require monitoring by distributors (“consecutive users”) who deliver water to metro customers not part of the City and County of Denver, such as Lakewood and Littleton. Details of addressing this challenge are being worked out cooperatively with our distributors.
