The parameters are standard. Originally the Clean Water Act published 21 contaminates in 1974…which has only grown to 92. Of the original 21 and the added contaminates, many MCL (Maximum Contaminate Level of Acceptance) have been reduced…and now many have MCLG (Maximum Contaminate Level Goal) meaning future reductions. Common sense then says the water we are told is safe to drink is not safe by future regulations. The link above does not list emerging contaminates i.e. pharma. However, Canadian media often publishes the issues of Prozac et.al. in most Canadian waters.
