Water Pollution Search

The Water Pollutant Loading Tool (Loading Tool) is a web-based tool that calculates and reports facility pollutant discharges in pounds per year or by monitoring period based on NPDES permit limit and DMR data.

The Water Pollution Search allows users to search for DMR or TRI pollutant discharges and the results provide top-ten lists of the largest surface water discharges. It prioritizes discharges based on total mass and toxicity to help identify discharges that may have the greatest impact on the environment or human health.
