ACI Research to be Highlighted in EPA Virtual Environmental Modeling Public Meeting


On August 5, 2020, the Environmental Protection Agency (EPA) will virtually hold its annual Environmental Modeling Public Meeting (EMPM). The EMPM is a public forum for EPA, pesticide registrants, and other stakeholders to discuss issues related to modeling pesticide fate, transport and exposure for pesticide risk assessments in a regulatory context. This meeting offers a forum for presentations on the Drinking Water Assessment Improvements for Surface Water Exposure.

The American Cleaning Institute (ACI) and Waterborne Environmental, Inc. abstract titled “Advances in down-the-drain chemical modeling with iSTREEM® to support environmental exposure assessments” will be presented during the meeting.

iSTREEM® ("in-stream exposure model") estimates down-the-drain chemical concentrations in wastewater treatment plant effluents, in streams and rivers impacted by effluents, and at drinking water intake locations. The model covers the continental U.S. and a few watersheds in Canada under mean annual and low-flow conditions. The model is web-based and accessible for public use.

In addition to the iSTREEM® presentation, the meeting will focus on:

  • New scenario development for the Pesticide in Water Calculator (PWC)
  • New methodology for incorporating percent cropped area (PCA) into refined drinking water assessments
  • New methodology for incorporating percent crop treated (PCT) into refined drinking water assessments
  • Automation tools developed for applying new methodologies
  • The drinking water assessment framework

The meeting will be held from 9 a.m. to 4:30 p.m. EDT. Registration is required. To attend or participate, please contact by July 29, 2020. Recordings will be made available after the meeting.
