The city should not be adding chemicals to our drinking supply and doing test on a segment of the population when the people affected are not informed nor consenting. We must not add any chemicals that are not absoultely required as Thunder Bay has been designated a "blue dot" community , a protector of water . We need to safe guard our water when it is a quickly becoming a scarce resource worldwide. Those responsible need to be upfront and get community wide approval before we further contaminate our precious water supply our very source of life.
