Non-Target Chemical Features for: De facto water reuse: Investigating the chemical space coverage of multiple chromatographic and ionization methods using non-targeted analysis on surface water and drinking water collected using passive sampling

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. This dataset is associated with the following publication: Batt, A., L. Brunelle, N. Quinete, E. Stebel, B. Ng, P. Gardinali, A. Chao, A. Huba, S. Glassmeyer, D. Alvarez, D. Kolpin, E. Furlong, and M. Mills. Investigating the chemical space coverage of multiple chromatographic and ionization methods using non-targeted analysis on surface and drinking water collected using passive sampling.
