EPA 537 PFAS Organic Carbon Test in Water
The U.S. Environmental Protection Agency (EPA) Method 537 is a critical analytical procedure designed to determine the total organic carbon (TOC) content of water samples, with specific focus on per- and polyfluoroalkyl substances (PFAS). PFAS compounds are synthetic chemicals widely used in various industrial applications. Their presence in water can pose significant health risks; thus, accurate and reliable testing is paramount for environmental protection and compliance.
Eurolab provides specialized services using EPA Method 537 to ensure the detection of organic carbon content, including PFAS components, in drinking water sources. This method involves several steps: sample preparation, digestion, and analysis via a TOC analyzer equipped with the necessary reagents. The procedure is stringent and follows international standards like ISO 16232-4 for ensuring accuracy and precision.
Sample preparation is crucial to the success of this test. It involves filtering water samples through specified pore size filters (typically 0.7 μm) to remove particulates, followed by dilution or concentration according to known methods. Digestion uses strong acids like nitric acid under controlled conditions to break down organic compounds into carbon dioxide and water. The analysis phase measures the CO2 generated from this process, which directly corresponds to the TOC content.
The analytical technique employed in EPA Method 537 is based on combustion followed by infrared detection. This approach ensures that all forms of organic matter present are converted to CO2, allowing for accurate quantification without interference from non-organic components. The method’s precision and accuracy are validated through inter-laboratory comparisons and adherence to strict quality control protocols.
Understanding the significance of PFAS compounds in water is essential for public health officials, regulatory agencies, and industries handling water resources. Detecting these substances early can prevent widespread contamination and guide appropriate remediation efforts. Eurolab’s expertise lies in providing precise and reliable data that inform decision-making processes related to water quality.
Compliance with EPA regulations requires not only accurate testing but also robust documentation practices. Eurolab adheres strictly to all relevant standards, including ASTM D5243-18 for TOC measurement and ISO 17025 accreditation requirements. Our commitment ensures that every test result meets stringent quality benchmarks, providing stakeholders with confidence in the integrity of our services.
In summary, EPA Method 537 represents a cornerstone in environmental monitoring programs aimed at safeguarding public health by identifying PFAS contamination in water supplies. Eurolab’s comprehensive approach to this testing ensures compliance with regulatory guidelines while delivering actionable insights into water quality.
