Clean Water Week Events Are Pouring in-Where is Your Event?

Our First Ever Cape Cod Clean Water Week is from September 13th-19th and we’re so excited by all the events on our roster spanning the entire Cape. We’d love to have your event included as well!

Clean Water Week is a community-centered celebration dedicated to protecting one of the region’s most vital resources—its water. Hosted by the Barnstable County Clean Water Center, this annual event brings together residents, visitors, scientists, policymakers, non-profits, pond groups, land trusts, students and more to raise awareness about water quality issues, while inspiring meaningful action.
