(a) The state board may order a public water system to monitor for perfluoroalkyl substances and polyfluoroalkyl substances, in accordance with conditions set by the state board. A laboratory that has accreditation or certification pursuant to Article 3 (commencing with Section 100825) of Chapter 4 of Part 1 of Division 101 shall perform the analysis of any material required by an order to monitor for these substances. The order shall identify the analytical test methods to be used by laboratories and provide for the electronic submission of monitoring results to the state board.

(b) An order issued pursuant to subdivision (a) may apply to an individual public water system, specific groups of public water systems, or to all public water systems. Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code does not apply to an order issued pursuant to subdivision (a) to specific groups of public water systems or to all public water systems.

(c) (1) If any monitoring undertaken pursuant to an order issued under subdivision (a) results in a confirmed detection, a community water system or a nontransient noncommunity water system shall report that detection in the water system’s annual consumer confidence report. Unless the water source is taken out of use or new data becomes available to show that the response level is no longer being exceeded, the community water system or nontransient noncommunity water system will provide notice of the exceedance of the response level in the water system’s annual consumer confidence report.

(2) In addition to the notification pursuant to paragraph (1), for perfluoroalkyl substances and polyfluoroalkyl substances with notification levels, a community water system or a nontransient noncommunity water system shall report the detection if the level exceeds the notification level as required by Section 116455.

(3) For perfluoroalkyl substances and polyfluoroalkyl substances with response levels where detected levels of a substance exceed the response level, a community water system or a nontransient noncommunity public water system shall take a water source where detected levels exceed the response level out of use or provide public notification within 30 days of the confirmed detection. For the purposes of this paragraph, notice shall be provided as follows:
