RSEI does not model other TRI-reported waste management activities, such as land application or underground injection, or transfers other than those to POTWs and incineration. Water Microdata files come in two basic forms: yearly shapefiles/text files containing toxicity-weighted concentrations for each affected flowline, and all-years discharge-based text files which contain modeled concentrations for individual discharges at each downstream flowline. In both cases, on-site discharges from TRI reporters are distributed separately from discharges from publicly-owned treatment works (POTWs) resulting from off-site transfers from TRI reporters.” [Quote from: https://www.epa.gov/rsei/rsei-data-and-modeling and https://www.epa.gov/rsei/rsei-data-dictionary-water-geographic-microdata] Original data were downloaded 22 July 2025 from http://abt-rsei.s3-website-us-east-1.amazonaws.com/?prefix=microdata2022/water/ by Naomi Yoder ([e-mail]).
