The associated manuscript reports the results of a repeated sampling of a watershed, including surface water and drinking water, that were analyzed with multiple non-targeted analysis (NTA) methods. About 130 chemicals were tentatively identified in the environmental samples, with no concentrations being reported with the non-targeted analysis. The results of this manuscript provide users of NTA with important information on which types of chromatography and ionization methods can be used to detect different classes of environmental contaminants, including PFAS, pesticides, surfactants, and pharmaceuticals. The metadata published here includes a list of all unidentified chemical features detected by each non-target method tested.
