Lab-To-State Portal Information

The Division of Drinking Water (DDW) is encouraging laboratories to utilize the Lab-To-State (LTS) Portal, a new method to electronically submit lead and copper data for public water systems for compliance with the Lead and Copper Rule (LCR). Environmental Laboratory Accreditation Program (ELAP) accredited laboratories can attend an informational webinar about the LTS portal and how to participate in submitting data for public water systems. More information about how to register for the Lab-To-State Portal can be found in the Lab-To-State Webinar Handout. Please contact the Data Management Unit at or (916) 322-9599 with any pertinent questions regarding this portal.
