15.06.060 POU and POE Treatment Device Technical Requirements for Water Systems. A. Each POU and POE treatment device for a water system must meet all of the requirements set forth below. 1. The POU or POE treatment device shall be selected from the California State Water Resources Control Board list of approved devices for the specific contaminant impacting the water system or shall be independently certified in accordance with the American National Standard Institute (“ANSI”) standards. 2. The POU or POE treatment device shall be approved by the Director, following a review of, without limitation, the POU or POE unit’s design, construction, treatment performance, waste disposal, and available field or pilot test results. 3. The POU or POE treatment device shall be installed, controlled, operated, and maintained by the water system, or a person under contract with the water system with the water system retaining responsibility, to ensure proper operation, maintenance, monitoring, and compliance with this Chapter and Monterey County Code Section 15.04.110 drinking water standards. For a mutual water company or shared well, if agreed upon by each property owner, the water system may delegate authority for installation, operation, maintenance, and sampling to each property owner. 4. If the POU or POE treatment device is a reverse osmosis system, it shall be equipped with a total dissolved solid in-line analyzer. 5. If the POU or POE treatment device utilizes an adsorptive media, the system shall be equipped with a totalizing flow meter, if requested by the Director. B. Pilot testing shall be performed by the water system, or a person under contract with the water system on each proposed type of POU or POE treatment device to establish its use limitations and operations and maintenance criteria, as well as verification that it will produce effluent that meets primary water quality standards under the water system’s expected influent water quality and flow conditions. 1. Prior to performing pilot testing, a pilot testing protocol shall be submitted to the Director for review, and the water system shall obtain Director approval of the protocol. 2. Pilot testing for a POU or POE treatment device shall be conducted in the manner and for the time period specified by the pilot testing protocol for that POU or POE treatment device. Water quality samples for the constituent of concern shall be collected upon initial installation and a second test shall be conducted eight (8) weeks after the initial test, and both shall be submitted to a laboratory. Each sampling event shall include a raw and treated water sample. The water system shall request the laboratory to submit sample results to the Director. 

15.06.070 POU and POE Treatment Strategy for Water Systems. Prior to installing a POU or POE treatment device, a water system shall comply with a Director-approved POU/POE Treatment Strategy. The POU/POE Treatment Strategy shall include all of the following: A. Specify the primary water quality standard for which treatment is proposed. B. A description of how the water system will determine the type, number, and location of the POU or POE treatment devices to ensure a sufficient number of devices are installed for human consumption at all locations where there will be human consumption or use for food preparation. C. The basis for the POU or POE treatment device selection. D. The qualifications and identification of the person(s) responsible for the POU or POE treatment device installation, operation, maintenance, and water quality sampling and analyses. For a mutual water company or shared well, if agreed upon by each property owner, the water system may designate each property owner as the person responsible for their own POU or POE treatment device’s installation, operation, maintenance, and water quality sampling and analyses. E. A consumer education program to be implemented prior to and following installation of the POU or POE treatment device. F. The authority that allows the water system’s representatives access to consumers’ premises for POU or POE treatment device installation, maintenance, and water quality monitoring, as well as the surveys necessary to meet Subsection (B) of this Section. For a mutual water company or shared well, if agreed upon by each property owner, the water system may designate each property owner as the person responsible for their own POU or POE treatment device’s installation, operation, maintenance, and water quality sampling and analyses. G. A plan to be used in the event an installed POU or POE treatment device fails to produce water that meets primary water quality standards that includes: 1. A consumer notification protocol, along with example notices, consistent with this Section 15.06.070; and 2. A plan for provision of an alternative water supply, meeting primary water quality standards, to consumers served by such installed POU or POE treatment devices. H. An ongoing consumer notification protocol that includes: 1. Notices in the language(s) appropriate for communication with the consumers, distributed by mail, email or other electronic form such as text messaging; and 2. Annual notices informing the consumers: a. That only the taps for which a POU or POE treatment device is installed provide water meeting primary water quality standards; and b. The purpose and operational requirements for using the in-line total dissolved analyzer, if applicable as per Monterey County Code Section 15.04.080(A)(4).
