The dataset contains the analytical results for environmental and quality-control replicate sample sets and the computed relative percent differences (RPD) greater than 25 percent for the data collected during the surface-water sampling for the Triangle Area Water Supply Monitoring Project. The data are from samples collected during October 2015 through September 2017. Several study sites contained in this dataset were sampled for other USGS projects during the same time frame. Unless the 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.

Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater in karst landscapes. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of Conservation (TDEC) was formed to investigate karst spring systems across the state utilizing fluorescent groundwater tracing, particularly in areas where these resources may be used as drinking water sources. In fall 2021, USGS and TDEC staff identified possible vulnerabilities or complexities that may exist within karst spring systems based...

These datasets contain information used to compile the report (USGS OFR 2019-1077). It contains water-quality data, analytical results of field blanks, and analytical results for environmental and replicate sample sets for surface-water samples collected during water years 2016 and 2017 for the Triangle Area Water Supply Monitoring Program (TAWSMP).

In 2016, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 551 million gallons per day (Mgal/d) from fresh water sources. Surface water accounted for 492 Mgal/d (89 percent) and groundwater accounted for 59 Mgal/d (11 percent). Population served by public-supply water systems accounted for 3.4 million people, almost 100 percent of the total population. Total domestic water use was estimated at 396 Mgal/d and it is represented as the summation of deliveries from public-supply water systems to domestic users and self-supplied domestic withdrawals. The average per capita domestic water use, which represents the daily water use for the population that is supplied by public-supply water...
