ASTM D7363 Perfluorinated Compounds PFAS in Hazardous Waste Test
The ASTM D7363 test method is designed to determine the presence and concentration of perfluorinated compounds (PFCs), specifically perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), in water. This test has been adapted for use in hazardous waste materials by regulatory authorities like the U.S. Environmental Protection Agency (EPA). The primary objective of this service is to ensure that facilities handling hazardous waste are compliant with stringent environmental regulations aimed at reducing PFAS contamination.
PFAS substances, while used in various industrial processes and consumer products for their heat resistance, water repellency, and non-stick properties, have been identified as persistent organic pollutants (POPs) due to their long-lasting nature in the environment. Their presence in hazardous waste can pose significant risks if not properly managed. This test is crucial for compliance with the EPA’s PFAS Action Plan which aims at reducing exposure and environmental contamination.
The ASTM D7363 method involves the extraction of PFCs from a sample using either solid-phase extraction (SPE) or liquid-liquid extraction followed by analysis via high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). This robust analytical technique allows for the detection and quantification of trace levels of these compounds in complex matrices such as hazardous waste.
The test procedure is critical for industries that generate PFAS-containing waste products, including but not limited to electronics manufacturing, semiconductor fabrication, and the production of textiles and leather goods. By ensuring compliance with PFAS-related regulations, this service helps protect public health and the environment from potential harm caused by these persistent chemicals.
Our laboratory employs state-of-the-art equipment and follows strict protocols to ensure accurate results. The test not only aids in regulatory compliance but also assists facilities in identifying any potential contamination issues early on, allowing for timely corrective actions. This proactive approach is vital given the long-term health effects associated with PFAS exposure.
| Step | Description |
