    • Analytical results for blanks collected during surface-water sampling at the Triangle Area Supply Monitoring Project study sites, North Carolina, October 2017 through September 2019

    Metadata Updated: January 21, 2026

    The dataset contains the analytical results for quality-control samples collected during the surface-water sampling for the Triangle Area Water Supply Monitoring Project. The data are equipment blanks, sampling-vehicle (ambient) blanks, and field blanks collected during October 2017 through September 2019. Several study sites contained in this dataset were sampled for other USGS projects during the same time frame. Unless the quality-control samples at these sites were collected in conjunction with the Triangle Area Water Supply Monitoring Project, the data for other projects are not included in the dataset.
