Chromium is an element found in air, water, rocks, soil, animals, gases, and volcanic dust.
Chromium 0 and VI are most often found in industrial areas (e.g., leakage, poor storage, or improper disposal from steel and pulp mills).
Chromium III helps the body use sugar, protein, and fat. It is not harmful unless levels are very high.
Chromium VI can cause lung and stomach cancer.
When regular monitoring shows total chromium levels are above the MAC, the water supplier must reduce the amount of chromium to a safe level.
If there is a problem with chromium in any public water supply, customers must be told right away. Another water source must be supplied to prevent health risks.
If you have a private water source, test your water regularly to make sure it is safe. Make sure to have your water sample tested by an accredited lab.
According to Health Canada, the MAC of chromium in drinking water is 0.05 milligrams per litre (mg/L).
After you have installed your system, have the treated water tested for chromium to make sure your system is working properly. Monitor and maintain your water treatment equipment according to manufacturer instructions.
If you have any questions about chromium in water, call
