About This Site

Commission on Pollution is an independent reference site about air and water pollution in the United States. It exists to solve one narrow problem: official environmental information is accurate but hard to read. Agencies write in acronyms and shifting units, and a person who just wants to understand a number on a report has to piece the vocabulary together from a dozen pages.

The guides here explain that vocabulary — what the Air Quality Index measures, what the six criteria pollutants are, what MCL and ppb mean on a water quality report, and how to find the official fact sheet for a specific chemical. A simple unit converter handles the mg/L, µg/L, ppm, and ppb conversions that come up constantly when reading water documents.

The site is written for the general reader: homeowners, renters, parents, students, and anyone who follows local environmental news. Every page links to the primary government or international source it draws from, so you can verify claims yourself.

An honest note on scope: these pages are reviewed reference material, not professional advice. Nothing here tells you what to do about a health concern, a test result, or a property issue. For those questions, the guides consistently point you toward the appropriate professionals and official agencies — that is where decisions belong.
