The Ultimate Well Water Test checks your well for 249 substances in one round. It is our most complete option for well owners who want a full answer, not a partial one.
Private wells do not get inspected by the EPA or any city water department. That job falls on you as the owner, which is why we built a test that covers bacteria, heavy metals, radon, pesticides, herbicides, and industrial chemicals like VOCs in a single kit.
Add our PFAS “Forever Chemical” Test if you also want to screen for 18 additional compounds this panel does not include. Or check our Basic (covers 53 substances) and Premium (covers 113 substances) well tests if your well does not need this level of coverage.
Every test we run includes free expert consultation to go over your results, free shipping both ways, and a money back guarantee.

Every test comes with step-by-step instructions on how to prepare your water source, collect your water sample, and prepare your sample for return shipment to our lab.
We’ll mail you a kit that includes everything you’ll need to collect a water sample and mail it back to us.
After the test is completed, we’ll email you an in-depth technical report with a full breakdown of your results.
We offer complimentary follow-up phone calls with our experts—and you’re always welcome to email us with questions anytime.
Well owners who have never done a full test are the best candidates for this one. So are homebuyers looking at a property with a private well, since most lenders never ask for water testing before closing.
You should also consider this test if your well sits near farmland, a septic system, an old landfill, or an industrial site. Runoff from any of those can reach groundwater long before you notice a change in taste or smell.
If your well already has a strange odor, cloudy look, or has made someone in your home sick, this panel is built to find out why.
We run every test inside our own lab in Leominster, Massachusetts. Your results come straight from us, not a subcontractor. That keeps our pricing fair and our quality consistent across every kit we send out.
Most labs stop at handing you a report. We do not. Every result comes with a free call to one of our water quality experts, so you understand what your numbers mean and what to do next.
ETR Laboratories has run water tests for over 30 years. We hold membership in the national Water Quality Association and the Massachusetts Ground Water Association.
Our reviews reflect the work we do. We hold a 4.8 out of 5 rating on Google, a 4.8 out of 5 rating on Angi from 342 reviews, and five-star ratings on Trustpilot.
Accuracy is at the core of everything we do, and through strict quality standards and a commitment to scientific excellence, we deliver results you can trust.
Yes. We ship to well owners across the country, not just in Massachusetts. Your kit arrives by mail with everything you need, and shipping is free both ways.
Once your sample reaches our lab, our own team runs the panel in house. You get an emailed report when testing is complete, followed by a free call to go over what it means for your well.
Lenders that require well water testing typically accept reports from an accredited lab, and ETR Laboratories holds ISO/IEC 17025 accreditation from ANAB. Check with your lender on their specific requirements before you order.
Yes. Every test comes with a money back guarantee. If something goes wrong with your order or your kit, contact us and we will fix it.
The CDC recommends checking for bacteria once a year at minimum. A full panel like this one is worth running every few years, or sooner if your water changes in taste, color, or smell.
Yes. The bacteria screen checks for total coliform, E. coli, and total bacteria count, the three markers most likely to spike after flooding or work done on your well.
Most lenders will not ask for it, so it is up to you or your inspector to order one. Our well maintenance guide covers what else to check before closing.
It can. Runoff from fertilizer, pesticides, and nearby septic systems can work its way into groundwater over years. This panel screens for the herbicides, pesticides, and bacteria tied to those sources.
If you live near Leominster, Massachusetts, you can hand deliver your sample directly to our lab at 60 Elm Hill Avenue. If not, use the prepaid return box included in your kit.
