Antibiotic Resistant Bacteria and Genes in Wastewater and Drinking Water

We’ve written about antibiotic (antimicrobial) resistance and “superbugs” several times in recent years, and based on what we continue to learn, there is likely more to come. Antibiotics are used widely in animal agriculture and aquaculture and are also found in wastewater. These pharmaceuticals are excreted by animals and people who are taking antibiotics and when unused pills and liquids are flushed down the toilet or poured into the drain. All of these actions result in antibiotics entering the water environment and our wastewater systems, and have contributed to antibiotic resistant bacteria known as ARB. I wrote in 2015 that “Responsible use and disposal of antibiotics will go a long way toward reducing the unintended consequences of their entering the waste stream.”... Read More »

Autumn: When Leaves Fall, So Can Water Quality

Now that summer is over—and hopefully the record-setting 2017 hurricane season—many of us can turn our attention to the cooler temperatures, shorter days and the colorful splendor of autumn leaves. Of course, all of those red, orange, and yellow leaves are short-lived and fall to the ground, forming truly massive amounts of organic debris. But did you know... Read More »

Superbugs and Sewage at the Beach

We seem to be reading and writing a lot about superbugs—antibiotic resistant bacteria that are responsible for at least 2 million infections (including healthcare-associated infections acquired while receiving medical treatment in a hospital) and 23,000 deaths each year in the US.1 But the recent discovery of the “superbug enzyme” NDM2 in bathing seawaters in Ireland...
