Disclaimer

This site is for general information only. It isn't medical, legal, engineering, or other professional advice.

• We never say your water is safe to drink. No website can do that. Only laboratory testing can measure what's in your water, and the results only describe the sample that was tested on the day it was collected.
• Use a state-certified laboratory. For testing, use a lab certified by your state for the contaminants you need tested. For help understanding your results and what to do next, contact your local or county health department.
• Health concerns go to a professional. If you think someone has been sick from water, or someone in your home is pregnant, an infant, elderly, or has a weakened immune system, talk to a doctor and your local health department.
• Rules and prices change. We link to sources and date each page, but agencies update their requirements, fees, and contact details. Always confirm with the original source before making decisions, including real-estate transactions that may be covered by state well-testing laws.
• Treatment decisions. Choosing, sizing, and installing treatment equipment depends on your full test results, how much water your well produces, and local codes. Use qualified, licensed professionals where your state requires them.
• No warranty. We work to keep pages accurate but can't guarantee they're complete, current, or error-free, and we aren't liable for decisions made based on this site.

If you spot an error, please let us know so we can fix it.
