Since 2002, Great Rivers has served Missouri and Southern Illinois, providing free and low-cost legal services to individuals, organizations, and citizen groups working to protect the environment and public health.

We work through the courts and administrative agencies to safeguard the environment by enforcing environmental laws, especially air and water pollution laws and laws intended to protect wetlands, floodplains, open space, and endangered species.

The issues which we address often have national significance, although the majority of our work is within Missouri and Illinois.
