Water Quality in Eagan
Eagan is a mature Dakota County suburb with primarily 1980s-1990s housing stock. Many Eagan homes are now in the window where original water heaters, softeners, and core plumbing are due for replacement, which makes maintenance plans particularly valuable here.
16
grains per gallon
Extremely Hard — advanced softener required
Outside the documented East Metro PFAS plume, but extremely hard water at 16 gpg is causing real damage to every Eagan home without treatment.
Primary water source
Municipal water from city wells drawing from the Prairie du Chien-Jordan aquifer system. Eagan operates one of the larger municipal systems in Dakota County.

Common Water Issues We Solve in Eagan
Most Eagan homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
Iron Staining and Discoloration
Many Eagan wells show elevated iron, causing orange staining on fixtures, laundry, and tubs. We diagnose ferrous vs. ferric iron on-site and install the right specialty filter.
Drinking Water Contaminants
Beyond hardness, Eagan tap water can carry trace dissolved metals, sediment, and chlorination byproducts. Under-sink reverse osmosis delivers cleaner drinking and cooking water than most bottled.
Aging In-Home Plumbing
Many Eagan homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.

My Eagan home was built in the 1990s — what plumbing is at end of life?
Most 1990s-built Eagan homes are due for: water heater replacement (typical 12-15 year lifespan), water softener replacement (typical 10-15 year lifespan), and dishwasher/laundry supply line refresh. The original copper supply system is usually fine but worth a visual inspection during a maintenance visit.
Is Eagan water PFAS-affected?
Eagan is not in the documented 3M PFAS contamination zone, which sits primarily in Washington County. Standard Eagan water treatment focus is hardness (typical 13-16 gpg) and the softer-source ration of dissolved minerals; PFAS filtration is not the standard recommendation for Eagan homes.
