Alliance for the Chesapeake Bay

The Alliance brings together communities, companies and conservationists to improve our lands and waters. We strive for clean streams and rivers flowing through resilient landscapes, cared for by the people who live, work, and play in the Chesapeake Bay watershed.

Chesapeake Bay Foundation

The Chesapeake Bay and its tributary rivers, broadly recognized as a national treasure, will be highly productive and in good health as measured by established water quality standards. The result will be clear water, free of impacts from toxic contaminants, and with healthy oxygen levels. Natural filters on both the land and in the water will provide resilience to the entire Chesapeake Bay system and serve as valuable habitat for both terrestrial and aquatic life.

Coalition for the Delaware River Watershed

The Coalition for the Delaware River Watershed unites organizations working throughout the region to enhance their capacity to effectively advocate for protecting and restoring the Delaware River Basin. We work to achieve this mission by coordinating communications, messages, and actions to foster accountability for success at the federal and state levels.


With PennEnvironment, you protect the places that all of us love and promote core environmental values, such as clean air to breathe, clean water to drink, and clean energy to power our lives. We focus on timely, targeted action that wins tangible improvements in the quality of our environment and our lives.


Citizens for Pennsylvania’s Future was created in 1998 as a statewide environmental advocacy organization. Since our founding, we have achieved significant legal and policy victories that reduce pollution and protect the environment. We have provided millions of dollars in pro bono legal services while setting critical precedents and enforcing environmental laws across the commonwealth.
