A report released by the Environmental Working
Group on December 20, 2010, spurred national interest in chromium in
drinking water. Fairfax Water wanted to take the opportunity to
answer some of the most common questions regarding the topic.
What is chromium?
Chromium is the 24th element on the periodic table. It is a
naturally occurring metal found in soils, plants, rocks, water, and
There are two common forms: Chromium III
and Chromium VI.
Chromium III is an essential human
dietary element found in vegetable, meats, fruits, grains and
Chromium VI, also known as
hexavalent chromium, is generally produced by industrial
processes such as steel manufacturing and pulp mills. It can
also be generated by converting natural deposits of chromium III
to chromium VI.
Has Fairfax Water tested for
hexavalent chromium (chromium VI)?
Yes. Fairfax Water has conducted testing for hexavalent chromium in
our raw (untreated) and finished (treated) waters.
Results of the monitoring program can be found here.
