Did you hear the one about the drugged drinking water?
The story that is, not a joke.
A vast array of pharmaceuticals — including antibiotics, anti-convulsants, mood stabilizers and sex hormones — have been found in the drinking water supplies of at least 41 million Americans, an Associated Press investigation shows.
To be sure, the concentrations of these pharmaceuticals are tiny, measured in quantities of parts per billion or trillion, far below the levels of a medical dose. Also, utilities insist their water is safe.
But the presence of so many prescription drugs — and over-the-counter medicines like acetaminophen and ibuprofen — in so much of our drinking water is heightening worries among scientists of long-term consequences to human health.
What?! How did THIS happen?
People take pills. Their bodies absorb some of the medication, but the rest of it passes through and is flushed down the toilet. The wastewater is treated before it is discharged into reservoirs, rivers or lakes. Then, some of the water is cleansed again at drinking water treatment plants and piped to consumers. But most treatments do not remove all drug residue.
And that’s not all…
Another issue: There’s evidence that adding chlorine, a common process in conventional drinking water treatment plants, makes some pharmaceuticals more toxic.
Sounds like we should be worried, right?
Ask the pharmaceutical industry whether the contamination of water supplies is a problem, and officials will tell you no.
Of course. They’re the pharmaceutical industry. Trouble is…
So much is unknown. Many independent scientists are skeptical that trace concentrations will ultimately prove to be harmful to humans. Confidence about human safety is based largely on studies that poison lab animals with much higher amounts.
So, we should be reassured, right?
Who knows, says the New York Times.
But how bad is it, exactly? The answers range in degrees of confidence and alarm, though no one was ready to predict imminent doom.
Which is reassuring, coming from the Times.
