So many have been complaining, so many have been wrong. About 1.5 million citizens residing in the European Union (EU) have signed a petition to block this approval.
When I first began designing water treatment (and water reuse) systems back in the 1970s, the primary method used to ensure that microbial populations were kept at bay was chlorination. At least in the States. Europe relied on ozonation. (Think about this for a second- when so many of your population was killed by chlorine gas during war time, you have a hard time thinking it’s a good thing to use to render your water safe.)
