How to choose a lab
- Pick a lab on the official list above that is certified for each test you need (bacteria and chemistry are often separate certifications).
- Ask for the lab’s own sample bottles and instructions; bacteria samples usually must reach the lab within 24–30 hours.
- Compare prices for a basic package (bacteria, nitrate, pH/TDS) and add arsenic or other metals where local data shows a risk.
- Be wary of free in-home tests from treatment-system sellers — see our salesperson checklist.
Questions
Where can I get my well water tested in Virginia?
Use a lab on Virginia’s official certified-lab list. We count 112 listed labs (excluding those marked as serving public water systems only), most in Richmond, Newport News, Wilmington. Confirm the lab is certified for the exact tests you need before you send a sample.
What should I test my well for in Virginia?
Test every year for bacteria (total coliform and E. coli), nitrate, pH and total dissolved solids (CDC). In Virginia, 1% of sampled wells with arsenic data were above the EPA limit, so include arsenic. Use our test helper for a list that fits your home.
Is there well water data for my county in Virginia?
Yes for 36 counties: we show the share of sampled wells above the EPA arsenic and nitrate limits, from the Water Quality Portal (USGS/EPA). These are monitoring wells as well as private wells, so test your own well.
