As we discussed in a previous blog
post, iron can be more than a hassle in the home. Its effects
range from a metallic taste in drinking water to ruined pipes and
Anyway you look at it, too much Fe = bad news.
Not all iron is created equal though. Some forms of the element
are more damaging than others, or more prevalent in private well
water in certain geographic situations. With that said, each
and every variation of iron needs a unique filtration solution to
help counteract its effects.
Together, the multiple forms of iron make up a formidable crew
of waterborne contaminants bent on ruining your day.
Dissolved or ferrous iron is the most common form of iron found
in private well water supplies. It goes by the aliases of "clear
water iron" or "soluble iron" as well. Dissolved iron lives in water with very, very
low oxygen levels, but if ever detected, this member of the iron
gang sings like a canary. Pour the water into a clear container and
leave exposed to the air.
If the water begins to turn cloudy or reddish, you have your
Particulate iron is Ferric iron. You know it by
the orange-brown stain or scale it likes to leave as a calling card
after making an appearance. But this kind of iron comes in two
types, filterable or colloidal. Count yourself lucky if the former
hits your home as a filter easily removes filterable iron.
His brother, colloidal is a different story.
Colloidal iron is made up of small particles, and need the
proper micron rating on the filter to remove them.

Organic bound iron is a professional fugitive. It attaches
itself to organic compounds in the water, like tannins, and sneaks
into private well systems. Filtering organic bound iron is a
challenge because it cannot typically be removed by particulate
filtration. Again, you may need to bring in
backup on this case.
The title of the toughest in the bunch may belong to iron
bacteria. Unlike its brethren, iron bacteria is actually considered a microorganism,
and not actually a type of iron. Bad tasting and odorous water are
hallmarks of iron bacteria, on top of slimy growths and
