Does anyone have knowledge as to whether the World Health Organization or the UN have set clean water standards for acceptable  levels water contaminants?  If so, for how many water contaminants?  Most importantly, how do any of the WHO or UN clean water levels compare to those EPA has established for the US?   This week, Florida Environmental Regulation Commission approved new 'safe' water levels of contaminants - expanding from 54 to 92 contaminants to be regulated.  However, the allowable level of certain contaminants was increased.  The FDEP cited EPA and international standards as the scientific basis for the changes.  It would be helpful to know if and where the variance in declared 'safe' levels of contaminants between the US and international sources might be.  Thank you.

I'm not sure about the WHO or UN, but in Europe the European Commission has set "Environmental Quality Standards" for 33 priority pollutants with a proposal in play to increase this to 48 ( http://ec.europa.eu/environment/water/water-dangersub/pri_substances.htm ). I don't know how these compare to EPA "safe" levels.
