News from Scientific American:
Only about half of the prescription drugs and other newly emerging contaminants in sewage are removed by treatment plants.
The scientists reviewed 10 years of data from wastewater treatment plants worldwide to see how well they removed 42 compounds that are increasingly showing up in the Great Lakes.
Six chemicals were detected frequently and had a low rate of removal in treated effluent: an herbicide, an anti-seizure drug, two antibiotic drugs, an antibacterial drug and an anti-inflammatory drug.
Caffeine, acetaminophen and estriol (a natural estrogen) also were frequently detected in sewage but had high removal rates.
The wastewater plants had a low removal rate (less than 25 percent chance of removing 75 percent or more) for 11 of the 42 chemicals.
I’m grateful that I live on a farm with a well and septic system. I know what is (and isn’t) flushed down my toilets AND my water comes from within the earth and not from somebody else’s recycled sewage. Yuck.
It might be time to bring back the outhouse. After all, if you can’t control what’s being flushed down (and ultimately brought back up as “clean water”) it’s probably the smartest and healthiest way to go. Progress….
