Wastewater monitoring results for the current week in Louisville-Jefferson County

Wastewater Monitoring Results

Since June 2020 Louisville’s Metropolitan Sewer District (MSD) and Louisville Metro Public Health and Wellness (LMPHW) have partnered with researchers from the University of Louisville's Envirome Institute to learn how sewage may indicate community health risk. We have collected over 3,000 samples to track more than 40 different diseases. We also contribute to the CDC's COVID Data Tracker.
