(a) It is the goal of STATE to protect residents from harmful toxins in drinking water.
(b) Accordingly, within 100 days the Department is directed to commence proceedings to establish state-level maximum contaminant levels (MCL) for likely or known carcinogens and toxic chemicals likely to pose a substantial health hazard in accordance with sections (c) and (d) below.
(c) Departmental action shall include (1) the establishment of state-wide maximum contaminant levels for PFOS, PFOA, and other PFAS compounds in public drinking water systems; (2) the establishment of state-wide maximum contaminant levels for chromium-6 in public drinking water systems; (3) the establishment of state-wide maximum contaminant levels for 1,4 dioxane in public drinking water systems; and (4) a Department directive to consider limits on other pollutants in public drinking water systems when two or more other states have set limits or issued guidance on a given pollutant(s).
(d) In proceedings pursuant to section (b) and (c) above, the Department shall review MCLs adopted by other states, the studies and scientific evidence reviewed by those states, material in the Agency for Toxic Substances and Disease Registry, and the latest peer reviewed science and independent or government agency studies, and shall adopt an MCL protective of public health, including vulnerable subpopulations such as pregnant and nursing mothers, infants, and children, that provides at least as much protection to such populations as any MCL or health advisory promulgated by the United States Environmental Protection Agency. The commissioner shall annually review the latest peer reviewed science and independent or government agency studies and undertake additional rulemaking if needed to comply with this paragraph.
