Chemicals stay in wastewater even after treatment
December 5, 2006
It's possible to be too alarmist about the issue, but there are some good reasons to be cautious about the chemicals that are washed down the drain in day-to-day life. There are some concerns that some of the more potentially-carcinogenic ones are going down the drain
and passing through wastewater treatment plants untreated. Most municipal wastewater treatment focuses on biological issues, like returning oxygen to the water and removing bacteria. Removing things like perfluorochemicals is a task that's never really been on the list.
