EPA Releases Latest UMCR Data
The U.S. Environmental Protection Agency is releasing the ninth set of national drinking water data collected under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) for 30 chemical contaminants: 29 PFAS and lithium. The Safe Drinking Water Act (SDWA) requires that every five years the EPA issues a list of unregulated contaminants to be monitored by public water systems. UCMR 5 was published on December 27, 2021, and large, medium, and a nationally representative sample of small public water systems have been collecting data on these 30 chemical contaminants since January 1, 2023. The data collected under UCMR 5 improves understanding of the prevalence and amount of 29 PFAS and lithium in the nation’s drinking water systems.
The ninth data release includes all results received for UCMR 5 since the start of monitoring through July 10, 2025. The data released to date now represent approximately 83% of the total results the EPA expects to receive by completion of data reporting in 2026. With the normal lag between sample collection, analysis, and reporting, the data represent approximately 9 (of 12) quarters of monitoring results (i.e., Q1 2023 through Q1 2025). The ninth data release includes approximately 1.7 million sample results for 9,950 public water systems. The EPA is updating results in the UCMR 5 Data Summary, UCMR 5 Data Finder, and Occurrence Data Files. The UCMR 5 resources and Q&A also reflect that certain PFAS for which monitoring data are being collected are part of the EPA’s April 2024 PFAS National Primary Drinking Water Regulation (NPDWR).
UCMR 5 ninth data release includes updates to:
- UCMR 5 Data Finder – Allows the public, along with federal, state, and local agencies, to easily locate, view, and summarize specific UCMR 5 results, as well as download those results to an Excel (.xlsx) spreadsheet. Results can be filtered by multiple fields. A video demo is available. Please use (and encourage others to use) this tool for accessing the publicly available results.
- Occurrence Data Text Files – Recommended for those interested in large-scale data processing using statistical or data analysis software. These files contain analytical results and the additional data element and ZIP Code information reported by participating public water systems.
- UCMR 5 Data Summary – National summary statistics by contaminant, health effects information, data considerations, and data definitions for the UCMR 5 Data Finder and Occurrence Data Text Files.
- UCMR 5 Q&A – Answers to common questions on accessing and understanding the UCMR 5 data, and on PFAS and lithium in drinking water.
Water Cybersecurity Recommendations
EPA is publishing a report titled, Securing the Future of Water: Addressing Cyber Threats Today. The report includes recommendations calling for a holistic approach to strengthen cybersecurity in the water sector by enhancing coordination and collaboration across government, associations, and water utilities. Systems are being encouraged to address unique needs, normalize and promote cybersecurity measures, and improve access to technical assistance. These recommendations were produced by a Water Sector Cybersecurity Task Force that EPA co-lead at the time they were developed.
There are several priority actions that accompany the recommendations, including the development of water-sector focused cybersecurity leadership training, increasing direct cybersecurity technical assistance, providing webinars and curated resources for utilities, integration of cybersecurity into operator certification and continuing education, coordination with state Chief Information Officers (CIO) Offices for Cybersecurity Support, and more.
EPA is taking action to advance the goals of the recommendations and priority actions. Learn more about the Water Sector Cybersecurity Task Force recommendations.
Cyberattacks against water systems have increased several-fold over the past few years and can disrupt or contaminate drinking water and compromise the treatment of wastewater. EPA, federal partners, and utilities have a collective responsibility to ensure that cyber threats do not imperil the critical lifeline of clean and safe water. Clean and safe water is central to strengthening the American workforce; powering industries — from auto manufacturing to Artificial Intelligence; and advancing energy dominance. In communities, it supports small businesses, hospitals, military bases, and schools. The Cybersecurity Task Force was formed by members of the Water Sector Government Coordinating Council (GCC) and Sector Coordinating Council (SCC), groups which connect EPA with partners from the national associations, state primacy agencies, water utilities and other representatives from the Water Sector.
National Water Quality Month
National Water Quality Month is observed every August in the United States. Its purpose is to raise awareness about the importance of clean water—not just for drinking, but also for recreation, agriculture, sanitation, and the environment. The history of National Water Quality Month dates back to the passage of the Clean Water Act (1972) and the Safe Drinking Water Act (1974). The goals for National Water Quality Month include:
- Promote the protection of water sources (like rivers, lakes, and aquifers).
- Encourage communities and individuals to reduce pollution and conserve water.
- Educate the public on how clean water impacts public health, wildlife, and ecosystems.
- Support legislation and initiatives that ensure safe and sustainable water management.
Things you can do this month and every month to support and celebrate clean water:
- Participate in stream or beach cleanups
- Plant trees to prevent erosion
- Join a local water quality monitor group
- Adopt a watershed
- Resist dumping chemicals/trash down drains or into bodies of water
- Use eco-friendly household products
- Conserve water at home (fix leaks, use water-efficient appliances)
- Support your clean water nonprofits
Buoy Sampling Charles River
Every 15 minutes, a self-contained solar powered buoy next to Boston’s Museum of Science takes measurements and then transmits the data in near real-time using telemetry for remote access to EPA’s website. EPA scientists and water quality managers then use the data to assess local, real-time water quality conditions and to help track cyanobacteria (blue-green algae) blooms. The sensors on this measure the following parameters:
- temperature
- dissolved oxygen
- specific conductance (conductivity)
- pH
- turbidity
- chlorophyll
- phycocyanin
This buoy has been tracking data for over 10 years. Live Water Quality Data for this Charles River buoy can be found here.

ACWA/EPA Water Reuse Webinar
ACWA and U.S. EPA will host a Water Reuse Webinar for state and federal officials on September 11, 2025, from 1:00 – 3:00 pm ET. Please register for the Zoom meeting here.
Presentations will be made by EPA (Dr. Sharon Nappier, introduction) and the authors of the Potable Water Reuse Report (Dr. Amy Childress and Trussell Technologies, Inc.). The 2-hour session will cover:
- The landscape of DPR regulations throughout the United States and internationally. The public health requirements and non-public health factors influencing state DPR regulations will be discussed. (Series 1)
- An introduction to pathogen reduction crediting frameworks. Because it is not possible to conduct real-time monitoring for pathogens, treatment processes receive log-reduction credits through experimental testing. However, some effective processes, like reverse osmosis (RO), are under-credited due to the lack of good surrogates. (Series 2)
- Open discussion on state needs regarding the development of microbial treatment targets and crediting systems for water reuse.
Please reach out to Ward Scott with any questions or issues.
ITRC: Overview of the Tire-Derived Chemicals 6PPD & 6PPD-quinone Training
Tuesday, October 7, 2025, 1:00PM-2:30PM EDT
REGISTER HERE
In October 2024, ITRC released the 6PPD & 6PPD-quinone Guidance Document to provide environmental professionals and communities with information about the current science and regulatory framework of 6PPD and 6PPD-quinone (6PPD-q). 6PPD-q is a contaminant of emerging concern and is a transformation product of the tire anti-degradant (6PPD), an antiozonant used in tires.
Join us for this ITRC training course to get a basic overview of the science and policy measures surrounding the Tire Anti-Degradants 6PPD and 6PPD-q. Attendees will gain insight into the current state of knowledge on topics such as: background and use of 6PPD in tires, toxicity in aquatic species and humans; occurrence, fate, and transport; measuring, mapping, and sampling; mitigation measures; and policy, regulations, and laws.
Currently, 6PPD is used in all tires and can contaminate stormwater and surface water anywhere tires are used. 6PPD-q was identified as a chemical fatal to coho salmon in 2020. Since that time, it has been documented as acutely toxic to multiple trout species found throughout the United States. 6PPD and 6PPD-q have been found in waterways, aquatic organisms, soils, air, and humans.
This training will introduce you to the ITRC 6PPD & 6PPD-quinone Guidance Document which provides more technical detail than can be covered in this training course.
ITRC: PFAS Chemistry Training
Thursday, October 9, 2025, 1:00PM-3:00PM EDT
REGISTER HERE
The Interstate Technology & Regulatory Council (ITRC) is presenting an introductory training on the basics of per- and polyfluoroalkyl substances (PFAS) chemistry. This training supplements the ITRC PFAS Introductory training and ITRC Beyond the Basics Training sessions. You can find ITRC PFAS training resources online at https://pfas-1.itrcweb.org/pfas-training/.
PFAS are an emerging group of contaminants that present unique challenges in many areas including: widespread use and presence in the environment, sampling and analysis, fate and transport, and remedial approaches. This training session will provide PFAS practitioners with an understanding of the unique aspects of PFAS chemistry that guide fate and transport, treatment, regulations, and decision-making on PFAS sites.
Key focus areas of the training include the following:
- Why are PFAS different from other organic chemicals?
- How are PFAS defined?
- How are PFAS manufactured and why does that matter?
- What are the differences between perfluoroalkyl and polyfluoroalkyl substances?
- What are the naming conventions used for the different types of PFAS?
- How are short-chain and long-chain perfluoroalkyl acids (PFAAs) defined?
- What are precursors and why are they important?
- What are some of the unique chemical properties of PFAS and why do they matter?
Resources and further details included in this training are in the ITRC Guidance Document (PFAS-1).
ITRC: Contaminants of Emerging Concern (CEC) Identification Framework Training
Tuesday, October 14, 2025, 1:00PM-3:00PM EDT
REGISTER HERE
In 2023, the ITRC Contaminants of Emerging Concern (CEC) Framework was published to help environmental regulatory agencies and other stakeholders identify, evaluate, and manage CEC’s while acknowledging uncertainties in their environmental fate and transport, receptor exposure, and/or toxicity. Such an approach can be conducive to improved allocation of regulatory response resources and provide a foundation for communicating potential risk to stakeholders.
The ITRC framework is comprised of a white paper and four associated fact sheets. In the white paper, CEC are defined as: “substances and microorganisms including physical, chemical, biological, or radiological materials known or anticipated in the environment, that may pose newly identified risks to human health or the environment.” The framework is meant to help environmental regulatory agencies and other stakeholders by providing examples of CEC monitoring programs and guiding the user through the process of identifying CEC key characteristics, how to communicate real and perceived risk from CEC to the public, and how laboratory analytical methods can be used in the identification process.
The ITRC CEC training presents this entirely new framework for identification, prioritization, and communication of CEC. This course includes the following topics:
- An overview of the framework, how and why it was developed, the factors that influence the creation of CEC management units at the state level, and a listing of existing CEC monitoring programs.
- A discussion of key variables that may be used as criteria to identify and prioritize CEC for response actions. This portion of the course includes a case study that illustrates how the identification and prioritization process works with an “unknown” chemical CEC.
- Practices and methods for stakeholder messaging and how to share incomplete information on CEC that could impact human health and the environment. This portion of the short course builds upon the ITRC Risk Communication Toolkit by providing additional detail addresses communications plans, message maps, and audience identification.
- A paradigm for how laboratory methods can be used to identify CEC ranging from:
- “Is compound X in the sample and at what concentration?” (i.e., known knowns) to
- “Which compounds from the list are in this sample?” (i.e., known unknowns) to
- “What is in the sample?” (i.e., unknown unknowns).
CEC are typically compounds or substances whose occurrence or effect is unknown but may or may not be understood through similar compounds or substances. This module includes a discussion of the use of targeted and untargeted analysis to identify a CEC.
Participants will learn the elements of the CEC framework and gain an understanding of the framework application from case studies. Participants are encouraged to review the ITRC CEC Framework prior to the class.
ITRC PFAS Introductory Training
Thursday, November 6, 2025, 1:00PM-3:00PM EST
REGISTER HERE
Per- and polyfluoroalkyl substances (PFAS) are a large and complex class of anthropogenic compounds whose prevalence in the environment are an emerging, worldwide priority in environmental and human health. The ITRC PFAS Team, formed in 2017, has prepared readily accessible materials to present PFAS information to stakeholders, regulators, and policy makers. The PFAS team represents a diverse cross-section of expertise and experience working on PFAS.
This training will include emerging science on PFAS, including topics such as Properties of PFAS, Fate and Transport, Sampling and Analysis, and Treatment Technologies. The technical presentations will be focused on those who are relatively new to PFAS. The training will last approximately 90 minutes and include time for questions.
ITRC: Microplastics Training
Thursday, November 13, 2025, 1:00PM-3:00PM EST
REGISTER HERE
In response to one of the biggest emerging environmental concerns, ITRC formed the Microplastics Team in 2021 to develop the Microplastics Guidance Document. Plastics have become pervasive in modern life and are now used in a wide range of commercial and industrial applications. Microplastics may result from the degradation and fragmentation of larger plastics, or they may be intentionally produced for specific applications and products. Regardless of their origin, microplastics are now ubiquitous in our environment. Because of their small size and pervasiveness in the environment, microplastics, along with any other contaminants which are adhered to the microplastics, may be inadvertently consumed by humans and other organisms.
The online ITRC Guidance Document is geared toward an audience with reasonable level of scientific understanding, but not microplastic-specific knowledge. The guidance provides a user with information on microplastics and the state of the applied science without having to go to the scientific literature.
The target audience for the guidance and this training course includes state regulators and environmental consultants, as well as community and tribal stakeholders.
The guidance and this associated training course uses a conceptual site model to navigate microplastics in the environment and explore the following general areas:
- An introduction to microplastics, their sources, and worldwide distribution
- The pathways through which microplastics can enter and travel in the environment and their distribution in various media (water, soil, sediment, air, and biota)
- A current look at the most common techniques and best practices for sampling and analyzing microplastics
- Potential human health and ecological risks associated with microplastics in the environment
- An overview of existing regulations related to microplastics and macroplastics at the state, federal, and international levels
- Examples of prevention and mitigation strategies and best management practices to reduce microplastics from entering the environment and the emerging technologies to abate, treat, and remediate microplastics once they exist in the environment
- Identification of data gaps and the need for further research
- Several case studies illustrating a range of current microplastics-related topics
Prior to attending the training class, participants are encouraged to view the associated ITRC Microplastics Guidance Document.
