                                 CODE OF VIRGINIA

SUPERVISION BY BOARD (§ 32.1-169)

A. The Board shall have general supervision and control over all water supplies
and waterworks in the Commonwealth insofar as the bacteriological, chemical,
radiological, and physical quality of waters furnished for human consumption may
affect the public health and welfare and may require that all water supplies be
pure water. In exercising such supervision and control, the Board shall
recognize the relationship between an owner&#8217;s financial, technical,
managerial, and operational capabilities and his capacity to comply with state
and federal drinking water standards.

B. The Board shall adopt regulations establishing maximum contaminant levels
(MCLs) in all water supplies and waterworks in the Commonwealth for (i)
perfluorooctanoic acid and perfluorooctane sulfonate, and for such other
perfluoroalkyl and polyfluoroalkyl substances as the Board deems necessary; (ii)
chromium-6; and (iii) 1,4-dioxane. Each MCL shall be protective of public
health, including of vulnerable subpopulations, including pregnant and nursing
mothers, infants, children, and the elderly, and shall not exceed any MCL or
health advisory for the same contaminant adopted by the U.S. Environmental
Protection Agency. In establishing such MCLs, the Board shall review the
recommendations of any work group convened by the Commissioner after July 1,
2022, to study the occurrence of such contaminants in public drinking water,
MCLs adopted by other states, studies and scientific evidence reviewed by such
states, material in the Agency for Toxic Substances and Disease Registry of the
U.S. Department of Health, and current peer-reviewed scientific studies produced
independently or by government agencies.
