Private wells are not regulated like municipal water systems. The Environmental Protection Agency sets drinking water standards for public systems, but private wells fall outside that oversight. That means testing responsibility falls entirely on the well owner, and finding accurate, location-appropriate information can be surprisingly difficult.
Well water testing is essential, but it is often confusing. Costs vary by location and lab. Test panels differ depending on the provider. Requirements change by state and county. Not every provider offers the same services, and not every lab is certified for every type of analysis.
Our mission is simple: help private well owners confidently answer three questions that come up every time someone needs to test their water:
We built wellwatertesting.com because we believe private well owners deserve a centralized, practical resource designed around these real questions. Not marketing spin. Not treatment equipment sales pitches. Just clear information and a directory of providers you can actually contact.
A directory built specifically for well water testing, combining local provider listings with educational guidance.
Each state page provides context on well water testing in that region, including common contaminants, typical testing scenarios, and links to providers. City pages drill down further, listing testing laboratories and sampling services that serve that specific area. Every listing includes provider type, contact information, and service indicators so you can quickly identify who to call.
Understanding what you are testing for matters as much as knowing where to test. Our contaminant guides explain common well water contaminants in plain language: what they are, where they come from, health considerations, and what to do if your test results show elevated levels. We cover bacteria, nitrates, arsenic, lead, iron, manganese, pH, hardness, and more.
Beyond finding a lab, well owners need to understand the testing process itself. Our blog and resource articles cover topics like how often to test well water, how to collect a sample correctly, what different test panels include, how to interpret results, and what to do when something comes back high. We write for homeowners, not water treatment professionals.
Our directory includes laboratories, environmental testing companies, and sampling services across the United States. We source listings from multiple channels to build as complete a picture as possible:
Each provider is classified based on available, verifiable information. Not all providers advertise clearly, so we use a transparent classification system:
Provider explicitly states they offer well water testing services. We have verified this through their website, direct contact, or official certification lists.
Services, reviews, or public information strongly suggest well water testing is available. The provider type and service descriptions align with testing services.
Provider type suggests testing may be available, but we recommend confirming directly before scheduling. This often applies to water treatment companies and environmental consultants.
This classification system is intentional. We believe it is better to be transparent about uncertainty than to overstate what a provider offers. We always recommend confirming service details, test panels, pricing, and turnaround times directly with the provider before scheduling.
We built this directory for real well water testing scenarios that people encounter every day.
Homeowners who rely on private wells for drinking water, cooking, and household use. Whether you are doing routine annual testing, responding to a change in water quality, or testing after flooding or well repairs, our directory helps you find a certified lab nearby. We also provide guidance on which contaminants to test for based on common regional concerns.
People buying or selling properties with private wells often need water testing for real estate transactions. Lenders may require test results before financing, and buyers want peace of mind about water quality before closing. Our directory helps you find certified labs that can provide documentation accepted by lenders and real estate professionals. We also explain what tests are typically required for home purchases and how long results take.
Certified laboratories and sampling services that want to reach well owners actively searching for testing. Our directory is specifically focused on well water testing, which means every visitor has intent. Providers can claim or add their listings, update service information, and reach customers in their service area. Premium listing options offer enhanced visibility and top placement.
Well water testing services and recommendations change over time. Laboratories expand their test panels. Providers adjust pricing and service areas. New labs open. Others close or change ownership. Availability shifts by location and season.
To keep the directory useful, we:
Even with ongoing maintenance, details can change quickly. That is why we position our directory as a starting point for your research, not a substitute for direct confirmation with the testing provider. Always verify service availability, pricing, and turnaround times before scheduling your test.
If you notice outdated information, a missing provider, or an error in a listing, please contact us. Improving accuracy helps everyone who relies on private wells.
