How’s my waterway – an app and a website by EPA which helps people to find out information on the condition of thousands of lake, rivers and streams across the United States. This app/website uses GPS technology or a user-entered zip code or city name to provide information about the quality of local water bodies. Recently a new version has been released which includes data on local drinking water sources, watersheds, permits that limit pollutant discharge into waterways and efforts to protect waterways.
