Fenceline Air Quality Monitoring
This article explores why fenceline monitoring networks are being installed, the available technologies that can be included, and key considerations for industrial facilities.
May 2025 news update on PFAS regulations
New updates on PFAS regulations were released in April 2025.
Ethylene Oxide Measurement Techniques Advancements
New updates on PFAS regulations were released in April 2025.
PFAS Strategic Roadmap Accomplishments and Future Outlook
We first reviewed the U.S. Environmental Protection Agency’s (EPA) PFAS Strategic Roadmap: 2021-2024 in March 2022, and have since posted periodic updates. With the recent conclusion of the 2021-2024 implementation period, we now reflect on accomplishments and speculate about potential future directions.
EPA Passes Final PFAS National Primary Drinking Water Regulation
EPA released the final National Primary Drinking Water Regulation (NPDWR) on April 10, 2024.
Industrial Fenceline Air Quality Monitoring
Fenceline air monitoring is becoming an increasingly important tool for industrial facilities as regulatory agencies and communities seek greater transparency around emissions and air quality impacts. By combining technologies such as open-path spectroscopy, point monitors, passive samplers, and low-cost sensors, facilities can develop monitoring networks that support compliance, improve environmental stewardship, and provide real-time insights into potential emissions.
PFAS Testing Techniques
PFAS testing methods are rapidly advancing as researchers work to improve the detection, monitoring, and understanding of thousands of PFAS compounds across air, water, and soil. While standardized air monitoring methods are still emerging, new analytical technologies and evolving regulatory requirements are expected to drive broader testing capabilities and increased oversight in the years ahead.
The Evolution of PFAS
PFAS are a large class of synthetic chemicals used in a wide range of products for their water, oil, grease, and heat-resistant properties, but growing concerns about their persistence in the environment and potential health impacts have led to increasing regulatory scrutiny. As federal and state agencies expand monitoring and enforcement efforts, industries across the PFAS lifecycle are preparing for evolving requirements related to measurement, reporting, and environmental management.
