Conformance Status

The Web Content Accessibility Guidelines (WCAG) standard defines requirements to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. “Fully conforms” means that the content meets all of the WCAG requirements at the specified Level without exceptions.

Pollution Systems website content posted since July 2023 fully conforms to WCAG 2.0 Level A. It partially conforms to Level AA.

Older content conforms to earlier versions of WCAG, for example, WCAG 2.0. Most of the older content is archived and will not be updated.
