Environmental Technical Advisory Committee (ELTAC)


The Environmental Laboratory Technical Advisory Committee (ELTAC) is an advisory body to the Environmental Laboratory Accreditation Program (ELAP) and other California regulatory agencies. The committee is established in the California Health and Safety Code, section 100863, which requires the State Water Board to appoint a "multidisciplinary committee to assist, advise, and make recommendations regarding technical, scientific, and administrative matters concerning the accreditation or certification of environmental laboratories."

ELTAC is governed by By-Laws adopted by committee members and approved by Division of Drinking Water executive management.

Mission Statement

(Established May 11, 2016)

ELTAC serves to facilitate transparency, as an inclusive conduit for the fair and balanced exchange of information and dialogue between the laboratory community, California regulatory agencies, data users, and ELAP. ELTAC works to provide support, critical stakeholder review, scientifically valid advice, and unbiased guidance to ELAP on technical issues and the foreseeable effects that ELAP regulatory decisions may have, to ensure public health and environmental protection. ELTAC partners with ELAP to create and maintain a high quality accreditation program to meet the needs of the laboratory community, California regulatory agencies, and data users.


The committee is composed of 16 appointed members representing a variety of expertise in the areas of environmental testing, laboratory accreditation, and method development and validation.  Members are selected by the Deputy Director of the Division of Drinking Water to serve a two-year term, and includes both regulated stakeholders, and data users. There are two types of members – voting representatives from the scientific and laboratory community and non-voting members representing state agency partners and the public.
