Atmos’ Water Testing Project for the DC National Guard stands as a testament to our commitment to precision and excellence in environmental sampling and analysis. Undertaken with a detailed approach, our team collected water samples from 20 designated sinks, adhering to stringent Bottle Selection and other Sampling Considerations for PFAS. Notably, the sampling process included the retrieval of essential field quality control (QC) samples, and the analysis encompassed an extensive list of analytes, aligning with EPA Method 537.1. Beyond sample collection, our dedication to transparency and accountability is evident in the comprehensive PFAS Sampling and Analysis Report, detailing project objectives, sampling procedures, and analytical results. Emphasizing adherence to State and Federal PFAS standards, this project not only showcases technical proficiency but also underscores Atmos’ commitment to maintaining the highest standards in environmental assessment.
