Summary

Optical spectra reported here are collected from 17 surface water sampling sites within the Fraser River, a headwaters drainage of the Upper Colorado River Basin in the central western United States. The sample collection was conducted as part of the partnership between the United States Geological Survey’s (USGS) Next Generation Water Observation System (NGWOS) and Proxies Project, in coordination with the USGS Colorado Water Science Center and California Water Science Center, and the East Grand Water Quality Board.

Purpose

This data release contains 4 files: 1) full fluorescence spectra in vectorized format, 2) full absorbance spectra, 3) summary optical measurements commonly used in statistical analyses 4) data dictionary containing more information for the full vectorized fluorescence and full absorbance spectra files. The full vectorized fluorescence and full absorbance spectra files provide results for absorbance and fluorescence analyses as well as curated fluorescence wavelength pairs and calculated arrays used for statistical analyses of source attributions as well as temporal trends and spatial patterns. The optical measurements reported here were collected to establish proxies or surrogates for per- and poly-fluorinated alkyl substances (PFAS) and a suite of 12 constituents of concern. The summary optical measurements provide in-depth information of samples that were included in this data release.
