Big news this week from the Associated Press on pharmaceuticals in our drinking water. In an interview on NPR's Talk of the Nation, American Rivers' Scientific and Technical Advisory Committee member Dr. Joan Rose, summed it by explaining that the close connection between human waste, animal waste and our drinking water supply essentially "short circuits the natural environment and leads one to be concerned."

The Associated Press released the first major report on pharmaceuticals in drinking water supplies in the U.S. this week, and the results aren't encouraging. Investigators found an array of pharmaceuticals from pain killers to antibiotics to mood stabilizers in the drinking water of 24 major metropolitan water suppliers. Even worse, thirty-four of the sixty-two water suppliers contacted by the AP couldn't provide results as they had never tested for pharmaceutical compounds.

I had a close friend here in Milwaukee who got really sick this summer from swimming in the lake while sailing after a dry weather overflow. She had no idea an overflow event had even occurred. This is pretty commonplace, and unfortunately, it's really difficult to correlate sewage overflows with illnesses contracted by recreational use, because so few people seek medical attention or make the connection that the water made them sick. There's a huge need to study that connection, but the records pretty much don't exist.

That's why the study we [Friends of Milwaukee's Rivers and the Emergency Department, Medical College of Wisconsin, Milwaukee, Wisconsin] focused on the drinking water connection, which freaked everyone out. It is highly likely that many of the kids in our study could have gotten sick from recreational use as well. We weren't able to isolate their exposure, but the hospital is now using questionnaires so we can try to get at that question in the future.

Pediatrics, a peer reviewed medical journal, recently published an article on our study of increased visits to a pediatric emergency room for gastrointestinal illnesses after releases of partially treated, or "blended" sewage, here in Milwaukee.

Here's the abstract of the report as it appeared in the journal Pediatrics.

Droughts across the U.S. are spurring drinking water authorities to develop creative and practical solutions to addressing the population's water demands. Orange County, California is even going so far as to recycle its own sewage grey water into pure drinking water:

From the LA Times:

If someone put a drop of sewage in a glass of water, would you drink it?

There's a storm brewing Down Under over sewage. Australia is experiencing its worst drought in a century and reservoir levels are falling to record lows. In the eastern state of Queensland, the water commission predicts that the state could run out of drinking water in the next two years. In response, Queensland has decided to use recycled sewage to refill reservoirs that supply public drinking water.
