Our commitment
HCI Environmental & Engineering Service wants everyone, including people who use assistive technology, to be able to learn about our services and reach us on this website. We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA, the standard referenced by the Americans with Disabilities Act guidance and California's Unruh Civil Rights Act.
What we have done
The site was built with accessibility in mind from the first page, and we test it with automated tools and manual checks across desktop, tablet and phone browsers.
- Semantic headings, landmarks and labeled form fields so screen readers can navigate each page
- Every control reachable and operable with a keyboard, with a visible focus indicator and a skip link to the main content
- Text and interface colors that meet WCAG 2.1 AA contrast ratios
- Text that can be resized to 200 percent and layouts that reflow on small screens without horizontal scrolling
- Descriptive alternative text on photographs and icons that carry meaning, and decorative images hidden from assistive technology
- Phone numbers presented as links so they can be dialed directly from a phone or screen reader
- Motion kept minimal and respecting the reduce motion setting in your operating system
Known limitations
Some content does not yet meet the standard. We are working on each item below and will update this statement as they are fixed.
- The regulatory fact sheets offered for download are PDF documents published by the California Department of Toxic Substances Control between 2004 and 2009. Some are scanned and are not tagged for screen readers. If you need the content of a fact sheet in an accessible format, contact us and we will help you obtain it or point you to the agency's current version.
- Embedded third-party content, such as maps, may not be fully accessible. The information shown in them, including addresses and phone numbers, is also provided as text on the page.
- Some photographs of job sites are described briefly. Tell us if a description is missing or unclear and we will improve it.
