OEHHA Web Platform

Public websites for the California Office of Environmental Health Hazard Assessment. The engagement covered the main site and the related public properties: Biomonitoring, Proposition 65 Warnings, Cases, EcoTox, and CalHeatScore, together with the MedPEST-ED learning site.

The work was a platform upgrade. The Drupal sites moved to Drupal 11 and PHP 8.5, and their databases moved from MySQL 5.7 to MySQL 8.4. The learning site moved forward on Moodle in the same program. Alongside the upgrades, the sites stayed current with security releases.
