Within the broader 3M plume footprint. Municipal water has tested within current EPA limits but PFAS monitoring continues. Many Stillwater homes are historic with galvanized supply lines that compound the hard water problem.
Primary water source

Common Water Issues We Solve in Stillwater
Most Stillwater homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
Iron Staining and Discoloration
Many Stillwater 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, Stillwater 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 Stillwater homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.
