(a) Commencing January 1, 2023, a person shall not manufacture, and offer for sale in the state, an endpoint device intended to convey or dispense water for human consumption that leaches more than one microgram of lead for test statistic Q or R, when normalized for a first draw sample up to or equal to one liter in volume, as calculated in accordance with the 2020 NSF International Standard 61, which became effective in the year 2020, and certified by an American National Standards Institute-accredited third party.
(b) Commencing July 1, 2023, a person shall not introduce into commerce or offer for sale in the state an endpoint device intended to convey or dispense water for human consumption that leaches more than one microgram of lead for test statistic Q or R, when normalized for a first draw sample up to or equal to one liter in volume, as calculated in accordance with the 2020 NSF International Standard 61, which became effective in the year 2020, and certified by an American National Standards Institute-accredited third party.
(c) The consumer-facing product packaging or product labeling of an endpoint device intended to convey or dispense water for human consumption that meets the “lead free” standard specified in subdivision (e) of Section 116875 and does not leach more than one microgram of lead for test statistic Q or R, when normalized for a first draw sample up to or equal to one liter in volume, as calculated in accordance with the 2020 NSF International Standard 61, which became effective in the year 2020, and certified by an American National Standards Institute-accredited third party, shall indicate that compliance by including the lettering “NSF/ANSI/CAN 61: Q ≤ 1” in an easily identifiable manner.
