Research Methodology & Source Evaluation
Policy Constraint: Zero fabricated citations, zero synthetic claims, and zero unverified research quotes. Every factual statement across our educational platform is grounded in published documentation from recognized public health agencies and building science institutions.
Hierarchical Source Selection Criteria
Our editorial desk evaluates literature according to an explicit 4-tier evidentiary hierarchy:
U.S. Environmental Protection Agency (EPA Indoor Environments Division), Centers for Disease Control and Prevention (CDC), Federal Emergency Management Agency (FEMA Building Science Branch), and U.S. Department of Housing and Urban Development (HUD Office of Lead Hazard Control & Healthy Homes).
Peer-reviewed technical bulletins from land-grant university extension departments (e.g., University of Minnesota, University of Florida IFAS, Cornell Cooperative Extension) focused on agricultural and residential moisture engineering.
Industry consensus standards such as the IICRC S500 Standard for Professional Water Damage Restoration and IICRC S520 Standard for Professional Mold Remediation.
Peer-reviewed indoor environmental quality literature indexed in PubMed, National Library of Medicine (NIH), and building science journals examining relative humidity, fungal aerobiology, and structural drying mechanics.
Source Audit Schedule & Update Cadence
All source records are maintained in a structured data registry with verified URL endpoints, publication dates, and review stamps. Content is audited semi-annually. If a primary agency document is updated or replaced, our curriculum is revised to reflect current scientific consensus.
Corrections & Verification Protocol
We encourage public review of all published guidance. If you identify an outdated link, an imprecise claim, or conflicting guidance, please submit a correction notice to our editorial team at support@motsdouarts.com. Validated corrections are published within 48 business hours with an updated review timestamp.
