Lead water line testing

My article today is directed to the 700 to 1200 or more homeowners, churches, commercial buildings, apartment buildings, and office buildings built in the early 50s or earlier who possibly have lead water lines from the city main line to the foundation of the building.
I am concerned as to the test results, if done, of the water in the locations mentioned.
As one should know one can phone the appropriate department at city hall to have a water test done which according to the province should be "No Charge."We know the lead water line in those specific locations start at the city main and runs directly to the foundation of the building, if one is considering installing a new water line, be aware the cost of installation should only be from the property line to the building.
The testing procedure as dictated by the province has been proven wrong for the simple reason flushing for 5 minutes before testing will remove any sediment build up in the pipes that has been sitting over night. The 5 minute flushing removes this sitting sediment that could possibly contain traces of lead therefore giving an incorrect reading.
There are now new regulations put in place by the province stipulating testing water that has been standing in the pipes and then test after flushing.
There is a much simpler method for testing, a method that will give a more accurate reading, a test the homeowner can do.
The first thing in the morning draw off a sample of water before using any water for washing, drinking, etc. Take a second sample after flushing the water for 5 minutes. Take a third sample at least 30 minutes later which allows the water to settle in the lines. For clarification tag each sample 1,2, and 3.
One could probably take the test samples to the proper city department but check first if you are allowed to do the testing yourself. If the testing is to be done by the city people insist the testing be done as per new revisions by the province to ensure one gets a proper reading. Remember one has the right to make this request as it is your health one is protecting.
Over the past few months people have been advised to use water filters that attach to the taps.
Recently the City of London advised the residents of London there were certain water filters in drinking pitchers that did not reduce lead content to a safe level.
Call city hall and ask if they can advise you what to use and not to use. I am sure if they don't know a simple call could be made to London where I am sure the makes would be made available to them.
