Even the cleanest wastewater contributes to more 'super bacteria', study finds

A new University of Minnesota study reveals that treated municipal wastewater -- even wastewater treated by the highest-quality treatment technology -- can result in significant quantities of antibiotic-resistant bacteria, often referred to as "superbacteria," in surface waters.

While the levels of overall bacteria were still relatively low in the surface water samples, researchers in the University of Minnesota study found that the quantities of antibiotic-resistant genes and human-specific bacteria were typically 20-fold higher at the site where treated wastewater was released into the Duluth-Superior Harbor compared to nearby surface water samples.

Makes one wonder what else is still to be discovered about quality of all waste management practices .......
