  • #EndPennEast

    Stop the PennEast Pipeline!

    The route of the proposed PennEast natural gas pipeline is planned to cut through ecologically-sensitive areas of Hopewell Township, devastating a 125-foot wide swath of protected forests, wetlands, open space, farmland, and pristine waterways in its wake. Help us defend the land we have worked hard to protect over the past 65 years. Click to learn more about this issue.

  • River Friendly

    Are you River-Friendly?

    The River-Friendly Certification Programs promote clean water and a healthy environment through voluntary action by individuals and institutions. To achieve these goals we work one-on-one with residents, businesses, golf courses and schools to improve land stewardship practices. The program works to reduce pollution, conserve water, restore habitat for wildlife and educate the public about becoming better environmental stewards. Become River-Friendly Today!
