Urban Waters Federal Partnership Cooperative Matching Funds Projects

Science Center Objects

The Urban Waters Federal Partnership (UWFP) reconnects urban communities with their waterways by improving coordination among federal agencies, particularly those communities that have been disproportionately impacted by pollution or economic distress. The UWFP draws upon Environmental Justice principals—the idea that all people, regardless of race, religion, national origin, or economic station, deserve fair treatment with regards to environmental laws and policy. 

The UWFP joins federal agency science and community-led revitalization efforts to improve our Nation's water systems and promote their economic, environmental and social benefits. The USGS joined the Partnership in Fiscal Year 2017 when the USGS National Water Quality Program (NWQP) was asked by Congress to make available Cooperative Matching Funds (CMF) to support water-quality related projects in designated UWFP locations. USGS UWFP activities include a wide range of water-quality related monitoring, assessment, management practice evaluation, and educational activities. These projects are done in cooperation with municipal, state, and regional partners focused on restoring and revitalizing urban waterways.
