PFAS in the Huron River — and what the city report confirms
Ann Arbor's water supply comes from the Huron River. State testing has documented PFAS compounds in the source water above EPA health advisory levels. The city treatment plant reduces them but does not eliminate them. For a family with young children, this was unacceptable. Marcus wanted whole-home coverage, not just a point-of-use filter.
Whole-home activated carbon removes PFAS before it reaches any tap.
Activated carbon is one of the most effective technologies available for PFAS removal. We sized a whole-home carbon system for their household flow rate, ensuring every tap in the house gets treated water. The 5-stage RO at the kitchen sink adds a second reduction layer for drinking and cooking. Carbon backwashes automatically. RO membrane gets replaced every 2 years.
Aqua Otter Whole-Home Carbon System
Catalytic carbon removes PFAS, chlorine, chloramines, and organic compounds at the point of entry.
5-Stage Reverse Osmosis
Provides a second barrier at the kitchen tap. RO removes any PFAS that passes the carbon plus all TDS.

“My wife is a physician and she brought home the Ann Arbor water report one night and that was it. We had the Aqua Otter team out within the week. The whole-home carbon plus the RO under the kitchen was exactly what the situation called for.”
