Florida now has a realtime webpage that residents can view to see the latest trihalomethane count in their drinking water. THM’s are chlorine byproducts and the unsolved problem of the most common method of water purification.
To quote the site,
“TTHMs are four organic chemicals which form as byproducts of chlorination. When chlorine is added to water that contains organic matter (such as algae, riverweeds or decaying leaves), residual chlorine molecules react with this harmless organic matter to form these organic chlorinated chemical compounds known as Total Trihalomethanes (TTHMs).”
Nice to know I guess. Better to fix it with a good water filtration system!
