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.
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 In 2017, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 545 million gallons per day (Mgal/d) from freshwater sources. Surface-water withdrawals accounted for 488 Mgal/d (90 percent) and groundwater withdrawals accounted for 57 Mgal/d (10 percent). Population served by public-supply water systems accounted for 3.5 million people, almost 100 percent of the total population. Public-supply water withdrawals were tabulated by municipality and by public water system.
Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 2015 through September 2016 (water year 2016). 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 by the PWSB either monthly or quarterly at fixed stations on 34 tributaries in the Scituate Reservoir drainage area. 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...

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.

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...
Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and elevations of observed water surface and recovered high-water marks are being provided at select locations because of the high water observed during bathymetric data collection after a spring flood in 2022.

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...

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 2018, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 593 million gallons per day (Mgal/d) from freshwater sources.

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...

This data release provides water chemistry results and quality assurance data for samples collected from Great Lakes tributaries in the states of Minnesota, Wisconsin, Michigan, Indiana, Ohio, and New York. In total, 158 chemicals were analyzed which are primarily pharmaceuticals. Between one and four water samples were collected at 37 sampling locations between November 2017 and July 2018 resulting in a total of 87 environmental, 95 field replicate, and 15 field blank samples. Of the 158 chemicals analyzed, 23 chemicals were detected in at least one regular sample. Detections per site ranged from 0 to 12 chemicals at concentrations of 1.56 to 30900 nanograms per liter. Sample collection and analysis was performed...

Tassi Ranch water trough with water from nearby Tassi Spring, 3 miles northeast of river mile 284.5.
In 2015-2016, physicochemical properties and chemical characteristics of stream water, bed sediment, groundwater, and soil were determined in watersheds located outside of, but in proximity to, the Peason Ridge Training Area and Main Post at the Joint Readiness Training Center and Fort Polk boundaries to document background trace element concentrations. Water samples were analyzed for physicochemical properties, major inorganic ions, selected trace elements, and dissolved organic carbon. Selected trace elements included antimony, arsenic, cadmium, copper, iron, lead, manganese, mercury, and zinc. Stream bed-sediment and soil samples were analyzed for major inorganic ions, selected trace elements, and grain size...
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...
