Heck yeah! I'm very concerned since my city has almost the same level of chromium-6 that was found in the Erin Brockovich case out in Hinckley, California.
It may be difficult to find statistics on Canada. According to this study, 89% of the cities surveyed by this environmental scientist group had Chromium-6 contamination above the maximum levels recommended by the California EPA. The U.S. national EPA does not regulate the amount of Chromium-6. The researchers are trying to get the U.S. EPA to set a national standard.
Homeowners can protect themselves by installing a reverse osmosis filtration system. However, the gear is pretty bulky and costs a couple of hundred dollars. I hope this is something that the water officials can address quickly.
