Just when we were starting to feel okay about consuming water straight from the tap, sex hormones, angina medication, anti-anxiety drugs, and over-the-counter pain killers like acetaminophen and ibuprofen have been found in drinking water systems across the country, according to the AP.
You know how it goes: you take drugs, you pee those drugs out, that pee goes into the drinking water? Sort-of, because that's apparently how drugs get into the water supply:
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 while researchers do not yet understand the exact risks from decades of persistent exposure to random combinations of low levels of pharmaceuticals, recent studies - which have gone virtually unnoticed by the general public - have found alarming effects on human cells and wildlife.
"We recognize it is a growing concern and we're taking it very seriously," said Benjamin H. Grumbles, assistant administrator for water at the U.S. Environmental Protection Agency.
Members of the AP National Investigative Team reviewed hundreds of scientific reports, analyzed federal drinking water databases, visited environmental study sites and treatment plants and interviewed more than 230 officials, academics and scientists. They also surveyed the nation's 50 largest cities and a dozen other major water providers, as well as smaller community water providers in all 50 states.
Here are some of the key test results obtained by the AP:
-Officials in Philadelphia said testing there discovered 56 pharmaceuticals or byproducts in treated drinking water, including medicines for pain, infection, high cholesterol, asthma, epilepsy, mental illness and heart problems. Sixty-three pharmaceuticals or byproducts were found in the city's watersheds.
-Anti-epileptic and anti-anxiety medications were detected in a portion of the treated drinking water for 18.5 million people in Southern California.
-Researchers at the U.S. Geological Survey analyzed a Passaic Valley Water Commission drinking water treatment plant, which serves 850,000 people in Northern New Jersey, and found a metabolized angina medicine and the mood-stabilizing carbamazepine in drinking water.
-A sex hormone was detected in San Francisco's drinking water.
-The drinking water for Washington, D.C., and surrounding areas tested positive for six pharmaceuticals.
-Three medications, including an antibiotic, were found in drinking water supplied to Tucson, Ariz.
Kudos to the AP for going all Erin Brockovich on us. Back to the bottled water.
