    • Appendix 2 - Analytical results for blanks collected from October 2013 through September 2015 during surface-water sampling at the Triangle Area Supply Monitoring Project study sites, North Carolina

    Metadata Updated: January 20, 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 sampling-vehicle (ambient) blanks and field blanks collected during October 2013 through September 2015. 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.
