EPA Releases How’s My Waterway Data Transparency Tool

Today (6/18), EPA released a new version of their How’s My Waterway online mapping application. How’s My Waterway draws from publicly available water quality data reported under Clean Water Act programs (305(b), 303(d), TMDL) to provide information to the community about the health of local waterways for swimming, aquatic life, and fish consumption. The updated How’s My Waterway incorporates additional information about public drinking water systems from the Safe Drinking Water Information System (SDWIS) and the Drinking Water Performance and Results Report (GPRA) to provide single point access to EPA water program data.

Created in partnership between EPA, states and water stakeholders, How’s My Waterway provides users with an easily accessible and understandable summary of water quality at the community, state, and national level.

  • Community: Learn about the health of local waters, identify challenges and learn about what’s being done to restore or protect the waters. Find out more about your drinking water. Discover if waters in your community are suitable for swimming or eating fish and if they support healthy aquatic life.
  • State: Choose a state to find basic facts about a state’s waters, summaries of specific water assessments, a statewide survey of water quality and state drinking water metrics.
  • National: Learn about the quality of water resources (lakes, rivers and streams, wetlands and coastal areas) across the nation and the main challenges to our water resources nationwide. You will also find information about national drinking water quality and national drinking water metrics.
