PFAS-affected — filtration + softener required
Inver Grove Heights municipal water has detectable PFOA. The 2025 Consumer Confidence Report (PWSID MN1190014) shows PFOA at a highest single test result of 1.1 ppt with a range of 1.0 to 1.2 ppt, currently below the EPA's 2024 finalized MCL of 4.0 ppt but actively detected. IGH is in Dakota County rather than the documented Washington County 3M plume zone, but the detection means whole-home certified PFAS filtration is worth considering. Hardness per the city's published CCR is in the 20 to 22 grain per gallon range, approximately 370 ppm. The city specifically recommends private water softeners. System pressure averages 75 PSI at the main, on the high end of the typical safe range, so a pressure reducing valve check is worth considering in older homes.
Primary water source
Municipal water from six city wells, 360 to 542 feet deep, drawing from the Jordan aquifer per the Inver Grove Heights 2025 Consumer Confidence Report (PWSID MN1190014). IGH operates its own treatment infrastructure with three water towers and two reservoirs containing approximately 10 million gallons of stored water.
Recommended treatment for Inver Grove Heights homes:
Advanced water softener plus whole-home PFAS filtration; PRV check on incoming line

Common Water Issues We Solve in Inver Grove Heights
Most Inver Grove Heights homes we visit fall into one of these four buckets. Free in-home test confirms which apply to yours.
PFAS Contamination
Inver Grove Heights is within the documented East Metro PFAS contamination zone tied to historical 3M discharge. Even with municipal treatment, many homes install a certified household PFAS filter as a defense-in-depth layer.
Drinking Water Contaminants
Beyond hardness, Inver Grove Heights 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 Inver Grove Heights homes are 30+ years old. Original water heaters, softeners, supply lines, and shut-off valves are often due for replacement. Proactive maintenance prevents emergencies.

Meet Matt
Inver Grove Heights Resident, Journeyman Plumber
Matt is a Journeyman Plumber on the A.J. Alberts team and lives in Inver Grove Heights. Before joining the company, he spent years installing new plumbing systems on new home construction, which means he knows exactly how a home's plumbing is built from the rough-in up. That perspective shapes how he approaches every service call and remodel job.
Most of Matt's work happens in Inver Grove Heights or the surrounding South Metro communities: Cottage Grove, Woodbury (where A.J. Alberts is headquartered), Rosemount, Afton, Eagan, Apple Valley, Mendota Heights, Maplewood, Lake Saint Croix Beach, Saint Paul Park, Newport, West Saint Paul, South Saint Paul, Sunfish Lake, Hastings, and Burnsville. He runs the lead remodel plumbing for several area general contractors and handles standard service calls in the same coverage zone.
Outside work, Matt is with his family. A little-known fact: his dad is an electrician, so he grew up around the trades. He highly recommends plumbing as a career to anyone considering it. Inver Grove Heights and surrounding South Metro customers can request him by name when scheduling.
"Before A.J. Alberts I did new home construction, installing plumbing systems from the rough-in up. So I know how plumbing works in any home. That perspective makes a real difference on service calls and remodels."

How hard is Inver Grove Heights water?
Per the City of Inver Grove Heights official Consumer Confidence Report, the water hardness level is 20 to 22 grains per gallon, approximately 370 ppm. That puts IGH in the extremely hard tier, right alongside Blaine. The city's own Q and A specifically recommends that residents soften water through privately owned softeners. A 48,000 to 64,000 grain capacity softener with a metered Fleck or Clack valve is the standard recommendation for a 3 to 4 person household.
Is there PFAS in Inver Grove Heights drinking water?
Yes, low levels. The 2025 CCR shows PFOA (perfluorooctanoic acid) detected at a highest single test result of 1.1 ppt with a range of 1.0 to 1.2 ppt. The EPA's 2024 finalized MCL for PFOA is 4.0 ppt, so IGH is below the federal limit, but PFOA is being actively detected. IGH is in Dakota County, not the documented Washington County 3M plume zone where contamination is far more severe, but the detection is real and worth addressing through whole-home certified PFAS filtration if it concerns you. The A.J. Alberts free in-home water test can confirm levels at your specific tap and recommend the right treatment.
