Every year I phone waterworks here in Calgary, and they fax me over a copy of their water test results. We have 2 treatment plants here, Bearspaw and Glenmore. The tests that they have are for the water leaving the plant(s). What it may pick up on the way, which plant supplies your house and whether you have plastic, copper or galvanized supply pipes in your home you should take into consideration when assesing your tap water.
