California Department of Public Health (CDPH), part of the California Waterboards at the time, issued a compliance order to the KVSP Water System for elevated arsenic levels. Part of the order required KVSP officials to post bulletins alerting prisoners of their consumption of water contaminated with arsenic and the possible health effects from long-term exposure. This notice was posted quarterly until 2012 when plant construction finally began, and was reproduced in several lawsuits filed by prisoners.
