New Study Finds That Even the Cleanest Wastewater Contains ‘Super Bacteria’

*University of Minnesota research suggests that wastewater treated with standard technologies contains far greater quantities*

MINNEAPOLIS / ST. PAUL — A new University of Minnesota study reveals that the release of treated municipal wastewater – even wastewater treated by the highest-quality treatment technology – can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as “superbacteria,” in surface waters.

The study also suggests that wastewater treated using standard technologies probably contains far greater quantities of antibiotic-resistant genes, but this likely goes unnoticed because background levels of bacteria are normally much higher than in the water studied in this research. (more…)
