PFAS News

Ultra Short Chain PFAS

We are excited to announce Weck Labs' new capability to analyze ultra-short chain PFAS targets in water samples! Using sophisticated LC-MS/MS technology, we can now accurately detect and measure ultra-short chain PFAS, including PFMOAA, PFPrA, TFA, PFMeS, PFEtS, and PFPrS, at low ng/L levels. Ultra-short chain PFAS, characterized by containing three or fewer carbon atoms, are particularly challenging to detect and remove due to their small size and high mobility in the environment. These compounds are industrially relevant and are used in the production of lithium-ion batteries, AFFF, and other fluorine-based compounds. Ultra-short chain PFAS targets also originate from the degradation of other PFAS compounds, such as atmospheric oxidation of volatile fluorinated compounds and certain PFAS destruction technologies. 

 

Our innovative method allows us to provide comprehensive analysis of both potable and non-potable water, ensuring precise and reliable results for our clients. With this enhancement, we are committed to delivering the highest quality water testing services to meet your environmental and regulatory needs.

EPA Releases Draft Sewage Sludge Risk Assessment for PFOA & PFOS


On January 14, 2025, the U.S. Environmental Protection Agency released the Draft Sewage Sludge Risk Assessment for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS). The draft risk assessment reflects the agency’s current understanding of the potential risks to human health and the environment posed by the presence of PFOA and PFOS in sewage sludge that is land applied as a soil conditioner, fertilizer surface disposal or incinerated.


Weck provides PFAS testing of soils, biosolids, wastewater and drinking water.

6 PPD-Quinone

6PPD, an antioxidant preservative used in nearly all tire manufacturing, can oxidize into 6PPD-quinone. 6PPD-quinone, was found to be the toxic chemical responsible for killing Coho salmon in areas with urban runoff. 6PPD is used as a preservative in nearly all tires and may be present in creeks and waterways near busy roads across the world. The fatal effects of 6PPD-quinone and other transformation products has been found to impact other species of fish as well.


Weck Labs offers EPA Method 1694 using LC-MS/MS technology. Weck can report 6 PPDD-quinone as will as other transformation products which been found to impact other species of fish as well:


6PPD-quinone

IPPD-quinone

77PD-quinone

DPPD-quinone

CPPD-quinone
