EPA Releases Initial Nationwide Monitoring Data on 29 PFAS and Lithium
First of 12 sets of data to be released through 2026, this information further
builds upon EPA actions to address PFAS in Drinking Water
WASHINGTON (Aug. 17, 2023) – Today, the U.S. Environmental Protection Agency
is releasing the first set of data collected under the fifth Unregulated
Contaminant Monitoring Rule (UCMR 5). In the latest action to deliver on
EPA’s PFAS Strategic Roadmap, UCMR 5 will provide new data that will improve
EPA’s understanding of the frequency that 29 PFAS and lithium are found in
the nation’s drinking water systems, and at what levels. The monitoring data
on PFAS and lithium will help the Agency make determinations about future
actions to protect public health under the Safe Drinking Water Act. This
action advances the Biden-Harris Administration’s commitment to combat PFAS
pollution and safeguard drinking water for all people.
“PFAS are an urgent public health issue facing people and communities across
the nation. The latest science is clear: exposure to certain PFAS, also known
as forever chemicals, over long periods of time is linked to significant
health risks,” said Assistant Administrator for Water Radhika Fox.
“That’s why the Biden-Harris Administration is leading a
whole-of-government approach to address these harmful chemicals. As part of
this commitment, EPA is conducting the most comprehensive monitoring effort
for PFAS ever, at every large and midsize public water system in America, and
at hundreds small water systems.”
The data collected under UCMR 5 will ensure science-based decision-making and
help EPA better understand national-level exposure to these 29 PFAS and
lithium, and whether they disproportionately impact communities with
environmental justice concerns. This initial data release represents
approximately 7% of the total results that EPA expects to receive over the
next three years. The Agency will update the results quarterly and share them
with the public in EPA’s National Contaminant Occurrence Database (NCOD)
until completion of data reporting in 2026. EPA continues to conduct research
and monitor advances in techniques that may improve our ability to measure
these and other contaminants at even lower levels.
EPA is acting to protect peoples’ health from PFAS in drinking water. In
March 2023, EPA proposed standards to limit certain PFAS in drinking water.
The proposal, if finalized, would allow public water systems to use results
from UCMR 5 to meet the rule’s initial monitoring requirements and to inform
communities of actions that may need to be taken. In the interim period before
the PFAS drinking water standard is final, EPA has established Health
Advisories for four PFAS included in the UCMR 5. EPA continues to advance the
science on the potential health effects of a wide range of PFAS, including
many of those monitored for under this program.
EPA is moving forward to expand the investigation and cleanup of PFAS
contaminated sites, including by finalizing new safeguards under Superfund to
hold polluters accountable for contamination from two widely used PFAS
chemicals. The Agency also recent issued its third order to require PFAS
manufacturers to conduct testing under EPA’s National Testing Strategy to
help EPA better confront these forever chemicals.
EPA is also deploying an unprecedented $9 billion, included in President
Biden’s Bipartisan Infrastructure Law, specifically to invest in
communities with drinking water impacted by PFAS and other emerging
contaminants. This includes $4 billion via the Drinking Water State Revolving
Fund (DWSRF) and $5 billion through EPA’s “Emerging Contaminants in Small
or Disadvantaged Communities” grant program. States, Tribes and communities
can further leverage an additional nearly $12 billion in BIL DWSRF funds and
billions more in annual SRF funds dedicated to making drinking water safer.
These funds will help communities make important investments in solutions to
remove PFAS from drinking water.

Background
The Safe Drinking Water Act (SDWA) specifies that every five years EPA is
required to monitor for priority contaminants that may be present in drinking
water but are not yet subject to EPA drinking water regulations. EPA uses the
Unregulated Contaminant Monitoring Rule (UCMR) to provide the agency and other
interested parties with nationally representative data on the occurrence of
contaminants in drinking water, the number of people potentially being
exposed, and an estimate of the levels of that exposure. These data can
support future regulatory determinations, the development of national primary
drinking water regulations (NPDWRs), and other actions to protect public
health. EPA’s Fifth Unregulated Contaminant Monitoring Rule (UCMR 5)
requires sample collection for 30 chemical contaminants (29 PFAS and lithium)
between 2023 and 2025 using analytical methods developed by EPA and consensus
organizations.
