Frequently Asked Questions about Well Water Testing

Quick, clear answers to the most common questions: where to get your well water tested, what to test for, how often to test, typical costs, and how to interpret results.

Most people go with a state-certified drinking water lab, their local county health department, or a private testing company that works with certified labs. The key is making sure whatever lab you use is actually certified for the tests you need. Our directory offers a searchable list of well water testing providers organized by state and city.
You have a few options: certified labs, county health departments, environmental testing companies, and some water treatment businesses that send samples out for analysis. When comparing, look for providers that are upfront about their certifications and turnaround times. Browse our directory to find testing providers in your area.
At minimum, once a year for the basics like coliform bacteria and nitrates. You should also test whenever your water looks, smells, or tastes different, or after flooding or any work done on the well.
That really depends on where you live and what's around you. If you're near farms, old pipes, or mining areas, you might need specific tests. But bacteria and nitrates are the ones most guidelines say to check regularly. From there, you can add things like metals, radon, or PFAS based on your situation. Our guides explain all contaminants and when to test for them.
Nope. The EPA rules for drinking water only cover public water systems. If you have a private well, keeping an eye on your water quality is completely on you.
It varies a lot depending on where you are and what you're testing for. A basic bacteria test is cheaper than a full panel. The best way to compare is to look at exactly what's included in each test, not just the price tag.
It depends on the test. Some bacteria tests need time to incubate, while chemistry tests are usually quicker. Ask your provider about both the lab time and how long it takes to get samples to them.
Follow whatever instructions your lab gives you, they matter more than you'd think. Generally, you'll use a sterile bottle they provide, avoid touching the inside of anything, and get it to them quickly (usually kept cold).
Home kits are fine for a quick check, but if you need results for something important like a home sale or a real health concern, most people go with a certified lab. The results are more reliable and you get proper documentation.
Coliforms are basically indicator bacteria. Finding them doesn't automatically mean your water is dangerous, but it suggests conditions where harmful stuff could show up. E. coli specifically points to possible contamination from waste. All contaminants are explained in detail on our contaminants index page.
The EPA sets standards that most well owners use as a guide. For example, nitrate should be under 10 mg/L, nitrite under 1 mg/L, and arsenic under 0.010 mg/L. Your lab report will usually tell you if you're over any limits.
Definitely. Plenty of contaminants like nitrates and arsenic don't change how water looks, smells, or tastes. Testing regularly is really the only way to know what's in there.
Don't wait if your water suddenly tastes or smells off, if someone in the house has unexplained stomach issues, if your well was recently worked on, if there was a chemical spill nearby, or after heavy flooding.
Usually, yes. Buyers, lenders, and home inspectors often want to see water test results, though requirements vary by state and loan type. Make sure you get a proper lab report that works for real estate transactions.
The EPA has a list of certification programs and labs by state. You can also check with your state's certification office to confirm a specific lab is certified for the contaminants you want tested.
Sometimes. Some counties and universities offer free or discounted screening events, though it depends on where you are and what time of year it is.
First, don't panic but don't ignore it either. Talk to your lab about what the results actually mean, consider getting a second test to confirm, and take precautions in the meantime if bacteria or anything serious showed up. Then focus on fixing the problem and testing again afterward.
A lab runs the actual tests and gives you a report. A field service comes to you to collect samples and handles getting them tested. A treatment company installs filters, softeners, UV systems, and such to fix problems, but they should always be working from actual test results.
