Methodology

1. Topic selection. Weekly review of search intent, reader corrections, and regulatory updates (EPA, CDC, state health departments).
2. Source collection. Tier 1 standards and agency publications first; Tier 2 vendor manuals and trade press for corroboration only.
3. Drafting. Mahesh Iyer writes the first draft with inline citations and worked scenarios; AI tools assist literature sweeps and proofreading under human direction.
4. Editorial review. Mateo García checks numeric claims, tone, and missing hazards before publish.
5. Update cadence. Each guide is re-reviewed every six months and immediately when a cited agency page changes materially.
