PFAS ASSESSMENTS FOR IDENTIFICATION OF SOURCES OF PFAS IN PUBLIC WATER SUPPLIES
(§ 62.1-44.34:30)

A. For every public water system, VDH shall assist the Department by on a
quarterly basis transferring to the Department all validated monitoring results
available to VDH under federal regulations or otherwise in VDH&#8217;s
possession that indicate PFAS MCL exceedances, including data generated by
VDH&#8217;s independent PFAS monitoring activities or submitted by public water
systems to VDH.

B. For every public water system for which VDH has notified the Department
pursuant to subsection A or the public water system has directly demonstrated to
the Department that PFAS in finished water has been detected above any PFAS MCL
using Method 533, Method 537.1, or other EPA-approved method for drinking water,
the Department shall develop and implement a plan to prioritize and conduct PFAS
assessments for identifying significant sources of PFAS in such public water
system&#8217;s raw water source or sources. Such prioritization plan shall be
developed within six months of the initial notification by VDH pursuant to
subsection A and updated annually thereafter.

C. In developing its prioritization for conducting PFAS assessments, the
Department shall consider (i) data and other information available from VDH
regarding public water supplies, including but not limited to applicable PFAS
data; (ii) any data or other information submitted directly to the Department by
public water systems on a voluntary basis; (iii) information from consultation
with VDH and public water systems with finished water monitoring results above
any PFAS MCL; and (iv) other data or information the Department considers useful
for setting priorities, including studies published in the scientific
literature.

D. In conducting PFAS assessments, the Department shall consider the results of
the self-reporting process required pursuant to &#xA7; 62.1-44.34:31, the
results of any effluent or instream monitoring required pursuant to &#xA7;
62.1-44.34:32 or otherwise conducted by or available to the Department, and
other PFAS-related data or information the Department deems useful for
identifying significant sources.

E. In its reports of PFAS assessments, the Department shall identify potential
regulatory and nonregulatory options for addressing each significant source of
PFAS. The goal of such assessments shall be to protect public health by reducing
significant sources of PFAS in raw water sources of public water systems and to
ensure, to the maximum extent practicable, that the costs of public water
systems are minimized.
