ETR Laboratories is accredited by ANAB for specific testing as listed in our scope of accreditation.
Grand Rapids draws city water from five wells, ranging from 140 to 572 feet deep. Iron Range bedrock naturally releases iron, manganese, and radon into local groundwater. Manganese exposure has been linked to attention and memory issues in children. Our in-house lab runs full metals and radiological panels on site, the same panels we use for other testing companies who send us their toughest samples.
Municipal treatment covers what leaves the plant, not what happens between there and your faucet. Older plumbing and fixtures can add lead or copper before water reaches your glass. Every ETR order comes with a free consult from a real water quality expert, not a call center rep. We've spent over 30 years spotting patterns a data sheet alone would miss, including subtle signs tied to plumbing age and fixture wear.
Homes outside city limits typically run on private wells with no routine oversight. Agricultural runoff and septic systems raise the risk of nitrates and bacteria reaching groundwater. ETR has completed over 1,000 in-field well inspections nationwide, and we've seen this exact combination of risks before. Every sample runs start to finish in our own lab, so rural well owners get results they can actually trust.

“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.”
Yes. Municipal treatment manages the source, but plumbing and fixtures between the plant and your tap can add their own risks. Taste and appearance tell you nothing about manganese, radon, or lead, and drinking water causes more health problems nationwide than most people realize.
Iron, manganese, and radon are common given the Iron Range bedrock under Itasca County. Rural well owners should also watch for nitrates and bacteria tied to agricultural and septic activity nearby. You can look up what each one is and how it gets into water in our contaminant glossary.
That report measures water quality at the point it leaves the treatment facility. By the time that water reaches a well pump or a home's plumbing, the picture can look very different, especially given how much of the country's water infrastructure is aging past its intended lifespan. The report your city mails you tells you about their system, not yours.
Yes. Radon gas occurs naturally in bedrock across northern Minnesota and carries no smell or taste. A dedicated radon in water test checks for it directly, since no visual sign will ever give it away.
For most homes in this area, the premium well water test covers 113 substances and fits the region's mineral risks well. Households facing heavier agricultural or septic exposure should look at the ultimate well water test, which screens 249 substances. If you're unsure, reach out before ordering and one of our experts will point you in the right direction at no charge.
Contact us and we will walk you through it. Every order comes with a free consultation from a water quality expert who explains your results in plain terms. We do not sell treatment products, so the guidance you receive has no agenda behind it, and our well and city water testing faq covers the scenarios we see most often.
Yes. Communities across the Iron Range sit on similar bedrock and face the same natural mineral exposure. If you're outside Grand Rapids proper, our full lineup of well water tests covers the kits available to you.
No shared results. Our laboratory holds our clients privacy to the highest regard, your results and information will never be shared. Be aware that state certified laboratories may be required to report your results to various government agencies.
