Milwaukee tests its Lake Michigan source more than almost any city in the country, and still can’t tell you what’s happening in your own pipes. ETR Laboratories closes that gap, with lab-run results and a free expert consult in every kit.

Milwaukee's water infrastructure earned a D grade despite the city's strong record on source water testing. Roughly 65,000 lead service lines remain active, concentrated in homes built before 1986. Lead produces no color, taste, or smell, so a service line like this gives no warning on its own. Our water quality experts have read this exact pattern in older Midwest housing stock for over 30 years.
Milwaukee Water Works has tested Lake Michigan for PFAS since 2008, well ahead of most utilities in the country. That diligence covers the lake itself, but the Milwaukee River Basin tells a different story, with firefighting foam near Mitchell Airport linked to contamination in Wilson Creek and the Kinnickinnic River. Homes on private wells or older plumbing near these waterways face a different exposure picture than the citywide lake average suggests.
Milwaukee disinfects with chloramine instead of straight chlorine, which cuts down on the byproducts most cities deal with from chlorine alone. That's a real advantage, but chloramine introduces its own considerations, including ammonia byproducts that a standard chlorine test won't catch. Our in-house lab runs the specific panels this treatment method calls for, not a generic disinfection byproduct screen built for a different city.

“The test was simple–collect a water sample from a faucet in the home. We sent the test to the lab and received a water quality analysis within a few days. The test included analysis of the water sample for the presence of: coliform bacteria, E. coli, iron, lead, pH, turbidity, and nitrates/nitrites.”
“Incredible lab, they really care about their customers. As someone who doesn’t know a whole lot about water quality, they took their time to help me understand everything about my water quality situation.”
Start with lead directly, since a service line gives no visible warning on its own. Our lead in drinking water test and copper in drinking water test cover the two metals the federal Lead and Copper Rule was written around.
Yes, especially if you're near the Milwaukee River Basin or Mitchell Airport, where local contamination sources differ from the broader lake average. Our PFAS "forever chemical" drinking water test gives you a number tied to your own address.
Hardness itself isn't dangerous, but it's worth understanding alongside your plumbing's condition. Our water hardness test confirms your levels, and our Langelier corrosion index tells you whether your water chemistry is likely to pull more lead out of older pipes.
That's likely chloramine, the disinfectant Milwaukee uses instead of straight chlorine. Our chlorine in drinking water test and ammonia test together confirm exactly what's present and at what level.
No. Private wells outside the municipal system get no routine oversight at all, regardless of how well the city tests Lake Michigan. Our well inspection services are built for exactly this kind of property.
The basic city water test covers the essentials if you're just getting started. For homes with a known lead service line or plumbing built before 1986, the premium city water test adds the metals and VOC panel worth having.
