Legal Actions

Did you know that under the Clean Water Act citizens have the right to file lawsuits against polluters? That’s right. Our Waterkeepers represent the residents of their watersheds to bring lawsuits against polluters when government agencies fail to do their jobs. Waterkeepers also bring legal challenges against governmental agencies when they fail to enforce the law. This is one important reason why you should report polluters to your local Waterkeepers so they can take action on your behalf. Waterkeepers Chesapeake takes legal action on behalf of our members, especially on issues that have regional or national impacts such as the relicensing of Conowingo Dam, construction of fracked gas pipelines, and the Safe Drinking Water Act.
