Between March 2002 and May 2011 periodic water level measurements were made in the well on the summit of Kīlauea Volcano using a 2,000-foot calibrated electric tape (Waterline Envirotech Ltd.) with graduations of 0.01 foot. Water level measurements resumed in March 2018. Calibration of the electric tape at the USGS Hydrologic Instrumentation Facility (HIF) in November 2018 revealed a displacement of 0.29 feet over 1,980 feet of the electric tape. We therefore estimate that the accuracy of the water level measurements is 0.3 foot (±9 cm). Water level measurements were referenced to the top of the wellhead, located at 1103 meters above sea level at the time of drilling in 1973.
Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 2016 through September 2017 (water year 2017). Water-quality samples were collected by the PWSB either monthly or quarterly at fixed stations on 36 tributaries in the Scituate Reservoir drainage area. These data were used to calculate instantaneous loads and yields of constituents in a report by the U.S. Geological Survey. Water-quality samples were collected following a strict sampling schedule so that water-quality samples would be representative of various weather conditions. Samples were analyzed at the PWSB water-quality laboratory at the P.J. Holton Water Purification...

In 2016, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 551 million gallons per day (Mgal/d) from fresh water sources.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...
Public-supply water withdrawals in Puerto Rico have been compiled annually since 2014 as part of an ongoing effort between the Puerto Rico Aqueduct and Sewer Authority and the U.S Geological Survey. In 2020, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 602 million gallons per day (Mgal/d) from freshwater sources. Surface-water withdrawals accounted for 537 Mgal/d (89 percent) and groundwater withdrawals accounted for 65 Mgal/d (11 percent). Population served by public-supply water systems accounted for 3.3 million people, almost 100 percent of the total population. Public-supply water withdrawals were tabulated by municipality and by public water system.

Surface-water withdrawals accounted for 527 Mgal/d (89 percent) and groundwater withdrawals accounted for 63 Mgal/d (11 percent). Population served by public-supply water systems accounted for 3.3 million people, almost 100 percent of the total population. Public-supply water withdrawals were tabulated by municipality and by public water system.
Water-withdrawal, water-use, and water-return information have been collected and compiled for each county in Georgia every 5 years since 1980 using data obtained from various Federal, State, private agencies, and on-line sources. For 2015, water use, water withdrawal, and water returns were estimated for each county in Georgia. Off-stream water use in 2015 is estimated for the categories of domestic use, commercial use, industrial use processing, mining use, irrigation use (subdivided into crop and golf course irrigation), livestock, aquaculture, and thermoelectric power cooling. Water-use trends from 1985-2015 have also been compiled for each water-planning region in Georgia.

Florida’s water resources have been managed by five water management districts since 1972. These five regional water management districts are the Northwest Florida, St Johns River, South Florida, Southwest Florida, and the Suwannee River. In 2015, the Southwest Florida Water Management District accounted for the largest amount of saline water withdrawn (5,135 Mgal/d) and the South Florida Water Management District accounted for the largest amount of fresh water withdrawn (2,792 Mgal/d). The South Florida Water Management District accounted for the largest amount of water withdrawn for public supply (1,118 Mgal/d), agricultural irrigation (1,380 Mgal/d), and recreation-landscape irrigation (263 Mgal/d), while the...

This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Minnesota that have been reformatted based on a USGS profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). The water-well records provided in this data set have not received additional processing or interpretation by the USGS beyond the GWML2 standardization. The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies...

Water samples for oxygen-18 and deuterium isotope determinations were stored unfiltered in 15 ml glass bottles and analyzed at the USGS laboratories in Reston, Virginia. Analysis of oxygen isotopes was according to the methods of Epstein and Mayeda (1953) with a precision of ±0.1‰, and the hydrogen isotopes were analyzed according to the method described in Kendall and Coplen (1985) and Coplen et al. (1991) with a precision of ±1.5‰. Ratios are reported relative to VSMOW. References: Coplen, T. B., Wildman, J. D., and Chen, J., 1991.

Samples for water chemistry analysis were filtered to 0.45 µm upon collection. Since the solute-rich samples continued to form precipitates, samples were filtered again immediately prior to analysis if needed. All samples were very rich in solutes and were analyzed at multiple dilutions (1:100 to 1:1000) to match instrument measurement ranges for various analytes. Water chemistry analyses were performed at the U.S. Geological Survey laboratories in Menlo Park, California. The concentrations of fluoride (F-), chloride (Cl-), sulfate (SO42-), and bromide (Br-) in samples were determined by ion chromatography with a Dionex ICS-2000, using a 250 mm Dionex IonPac AS18 column. The concentrations of major cations...

Chemistry and Isotope Data Sample Collection: Water samples were collected from approximately 100 feet (30 meters) below the water table using either a 4 foot or 6 foot long stainless-steel bailers with an inner diameter of 0.5 in. Samples for anion concentration measurements were poured into 60 ml polypropylene bottles through 0.45mm pore-diameter filter. Raw (unfiltered, unpreserved) samples for oxygen-18 and deuterium isotope analyses were stored in 30 ml glass bottles. Sample Analyses: The concentrations of sulfate (SO42-), chloride (Cl-), and fluoride (F-) in samples collected until October 2003 were determined with a Dionex DX-300 ion chromatograph, and since October 2003 with a Dionex ICS-2000 ion chromatograph...
