About 43 million Americans rely on private wells for drinking water. Unlike municipal water systems, private wells are not tested or regulated by the government — that responsibility falls entirely on the homeowner. YourWaterReport gives you the county-level data you need to make an informed decision about testing and treatment.
Step 1: Enter your county
Search by ZIP code or county name to pull up your local well water data. We cover every county in our supported states, with data sourced from the EPA Water Quality Portal, USGS National Water Information System, and CDC.
Not sure what county you're in? Enter your ZIP code — we'll find it for you.
Step 2: See your contaminant report
Your county report shows which contaminants have been detected in local groundwater samples, at what concentrations, and how those levels compare to EPA health limits. Each contaminant is assigned a risk level based on:
- Whether detected concentrations exceed the EPA Maximum Contaminant Level (MCL)
- Detection frequency — how often the contaminant shows up in samples
- The number of groundwater samples analyzed for that county
We also show you which contaminants are most commonly detected in your area, so you know what to prioritize.
Step 3: Get your recommended test
Based on your county's specific contaminant profile, we recommend the right water test panel for your situation. Rather than a one-size-fits-all test, we match you to a panel that covers the analytes most relevant to your local geology and historical detection patterns.
Testing is done through state-certified labs using water drawn directly from your tap. Results are typically returned within 5–10 business days.
What our data is — and isn't
County-level data is a screening tool, not a substitute for testing your own well. Groundwater varies significantly within a county based on well depth, aquifer type, and local land use. Two neighbors can have very different water quality.
Our data tells you what contaminants have been found in your area and whether the pattern warrants concern. Your own test tells you what's actually in your water.
