Enforcement and Compliance History Online (ECHO) Water Pollution Search

Enforcement and Compliance History Online (ECHO) Water Pollution Search is an online tool that allows users to search discharge monitoring reports (DMR) and the Toxic Release Inventory (TRI). The tool allows the user to search by reporting year (data available for 2007-2018), discharge area (specific location or watershed), pollutant (i.e., nitrogen, phosphorus, metals, etc.), and the discharging industry or facility (i.e., publicly owned treatment works, industrial point sources). The goal of the tool is to increase awareness and transparency in order to encourage compliance with pollution regulations.
