Extremely Hard — advanced softener required
St. Paul Regional Water Services has tested within current EPA limits but St. Paul borders the East Metro PFAS zone. Extremely hard water at 15 gpg is an additional reason every St. Paul home needs treatment.
Primary water source

Common Water Issues We Solve in Saint Paul
Most Saint Paul homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
Chlorine and Chemical Taste
Saint Paul municipal water often carries detectable chlorine taste at the kitchen tap. An under-sink RO or whole-home carbon filter removes it cleanly and improves drinking water quality.
Drinking Water Contaminants
Beyond hardness, Saint Paul 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 Saint Paul homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.
