Understanding Pickering's water
Source: Durham Region's reports don't list hardness.
Where does Pickering's water come from?
Most of Pickering is supplied by Durham Region with Lake Ontario water treated at the Ajax Water Supply Plant. It's treated to meet safety standards, but it carries the hardness typical of Lake Ontario water and a chlorine taste or smell. Durham Region's annual reports don't publish a hardness figure, so the quickest way to know your number is our free in-home test.
