Editorial and Corrections Policy

Our goal is to publish practical, accurately sourced radon information while clearly separating educational content from our commercial referral service.

Editorial owner: The SpokaneRadonMitigation.com editorial team is responsible for the content on this site. The most recent material review date is shown on pages where changing guidance or safety information matters.

Source standards

We prefer primary public-health and government sources, including the U.S. Environmental Protection Agency and Washington State Department of Health. Local geology statements are tied to identified government assessments or research summaries. Citations are placed near consequential claims so readers can inspect the source directly.

Review process

Before publication, we check that safety thresholds, testing guidance, timelines, geographic claims, and descriptions of mitigation methods match the cited material. We avoid presenting a county radon-zone classification as an individual property result. We also distinguish what this website does from what an independent contractor or tester does.

Commercial independence and conflicts

SpokaneRadonMitigation.com may earn a referral or marketing fee from a provider that responds to a service request. That commercial relationship does not permit a provider to rewrite cited public-health guidance. Provider availability, credentials, recommendations, estimates, and work are independently confirmed between the visitor and the provider.

Corrections and updates

We review correction requests against the cited source and update material errors as promptly as practical. Significant corrections will be reflected in the page’s review date. To report a possible error, identify the page, the statement, and the supporting source below.
