Creates provisions related to the maximum contaminant level of vinyl chloride in drinking water

HB 1871 establishes a schedule for lowering the maximum allowable amount of vinyl chloride in public drinking water systems. The bill requires water providers to reduce this contaminant level to 1.8 parts per billion by January 1, 2025, and decrease it further by 0.2 parts per billion each year until reaching 1 part per billion by January 1, 2029. Additionally, the legislation mandates that any existing rules set by the relevant commission must be updated to align with these new safety standards. This measure directly impacts public water systems and the state agency responsible for regulating water quality.
