Lower White River pH informational workshop

Total Maximum Daily Load

June 28, 2022, 2 p.m., Online webinar

Learn about the Lower White River draft water quality improvement plan now available for comment.

During the workshop, we will explain:

  • The cleanup plan, including our monitoring and modeling work
  • The proposed phosphorus load reductions for point sources like wastewater treatment plants
  • Best management practices needed to address nonpoint sources like agricultural runoff

The online workshop will include a presentation followed by a question-and-answer session. Please register before the meeting, using the link below.

The federal Clean Water Act requires states to develop a Total Maximum Daily Load (TMDL) — or water quality improvement project — plan for each water body on the state's polluted waters list, also known as the 303(d) list. This science-based approach assigns a numerical value that represents the highest amount of a pollutant a surface water body can receive and still meet the water quality standards. Learn more about the TMDL process.
