Phosphorus Limits & Updated Solutions for Badger Mill Creek

Excess phosphorus is harming Wisconsin waters, making water quality standards increasingly restrictive. The Wisconsin Department of Natural Resources (WDNR) enforces these standards through the federal Clean Water Act and the state’s Phosphorus Rule, established on December 1, 2010. These rules set maximum thresholds for phosphorus in Wisconsin’s surface waters and set procedures through permits designed to help curb the growing issue.  Due to Phosphorus Rule requirements, Madison Metropolitan Sewerage District must develop a compliance solution for Badger Mill Creek, one of our discharge streams, through Project PLUS (Phosphorus Limits & Updated Solutions).  

What is Project PLUS?

Reducing phosphorus pollution requires continual, long-term strategies, but all citizens can take action to protect our lakes and streams. Through technical assessments, community engagement and ongoing partner conversations, PLUS has three goals: 

  1. Achieve phosphorus compliance standards.   
  2. Minimize harm to the biology of the stream.
  3. Maintain fiscal responsibility to ratepayers and owner communities.

Even small increases in phosphorus can fuel substantial increases in aquatic plant and algae growth, reducing recreational use, property values and public health.

The District will hold an in-person listening session at the Verona Public Library on Wednesday, November 30 at 6:30 p.m. Please RSVP, as space is limited.

A virtual listening session will be held via Zoom on Thursday, December 8 at 6:00 p.m. to ensure all owner communities have the opportunity to learn about the project. Watch for more information to come.
