The information on this website is provided in good faith for general educational purposes about radon, vapor intrusion, and mitigation practices in the Phoenix, Arizona area.
Health information referenced here, including statistics about radon and lung cancer risk, summarizes published guidance from public agencies such as the US EPA and state health authorities. It is not medical advice. For questions about your personal health or radon exposure history, consult a physician.
Statements about typical radon levels, geology, and local conditions describe patterns we and public datasets have observed; they cannot predict the level in any individual building. The only way to know a building's radon level is to test that building.
References to government programs, cleanup sites, regulations, and standards are provided for context and were accurate to the best of our knowledge when written; agencies update their guidance and site information over time, and their official websites are the authoritative source.
Nothing on this site creates a contractor-client relationship. Services are provided under written agreements on a per-job basis.
