Well Water vs. City Water Treatment: Iron, Sulfur, Bacteria & Hardness

Municipal Tap Water vs. Private Well Water

While city tap water is regulated under the EPA Safe Drinking Water Act and disinfected with chlorine or chloramines, private water wells are completely unregulated by federal agencies. Homeowners with private wells are solely responsible for testing and treating their own water supply.

Common Well Water Contaminants (Iron, Manganese & Sulfur Odors)

Private well water frequently contains dissolved ferrous iron (causing reddish-brown stains on toilets and laundry) and hydrogen sulfide gas (causing a pungent 'rotten egg' odor). Standard carbon pitcher filters cannot eliminate heavy iron or sulfur gas.

Air Injection Oxidation (AIO) Systems for Well Water

The gold standard for treating iron and sulfur in well water is an Air Injection Oxidation (AIO) filter system. AIO systems inject oxygen into a specialized filtration tank to oxidize dissolved iron and sulfur into solid particles, which are then backwashed away automatically without harsh chemicals.
