*These PFAS samples were collected opportunistically by collaborative partners in 2009 and 2010 from marine waters and major rivers across the state. The FMP did not have direct control over the collection, processing, or storage of samples prior to the chemical analysis. Although sample collection followed standard collection protocol established for evaluation of other environmental contaminants, they were not those specifically developed for PFAS compounds. The general protocols are not designed to prevent cross-contamination of samples with PFAS from outside sources (e.g., rain gear, collection supplies, or processing equipment). Therefore, results from individual samples should be interpreted with caution. Note that none of these samples were collected from a known contaminated site. They should be considered reference samples containing only background levels of PFAS compounds, not a definitive characterization of the species or location.
