This data release provides a comprehensive dataset of sampling-site characteristics and baseline groundwater-quality data collected from a network of multilevel sampling wells installed in a densely developed coastal neighborhood undergoing a conversion from onsite septic systems to municipal sewering. Groundwater samples were collected during multiple events from a total of 227 well screens at 15 locations using a peristaltic pump between June 2016 and September 2021. Samples were collected and preserved following methods documented in the U.S. Geological Survey National Field Manual (variously dated) and Savoie and others (2012). This dataset provides well construction information, groundwater levels, water-quality...

This U.S. Geological Survey data release provides detailed sampling site information, hole and well construction details, and data dictionaries necessary to interpret historical and future physical, chemical, and biological data sets derived from samples collected and measurements made in association with the National Crude Oil Spill Fate and Natural Attenuation Research Site. In 1979, a high-pressure pipeline carrying crude oil burst near the city of Bemidji, Minnesota and spilled approximately 1.7 million liters (10,700 barrels) of crude oil into glacial outwash deposits (Essaid and others, 2011). Since 1983, scientists with the U.S. Geological Survey, in collaboration with scientists from academic institutions,...
The U.S. Geological Survey (USGS), in cooperation with the Harris‐Galveston Subsidence District, City of Houston, and the Fort Bend Subsidence District, produced a dataset through 2022 of compaction values in the Chicot and Evangeline aquifers in the greater Houston area, Texas. This dataset contains compaction values associated with subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously using analog technology at 14 extensometers at 12 locations (a pair of extensometers are installed at different depths at 2 of the 12 locations). Of the 14 extensometers, 13 were activated between...

The data set includes temperature data from the base of the water column and below the bottom of the Indian River Lagoon, Brevard County, Florida. Data were collected near Eau Gallie, Melbourne, Florida and Riverwalk Park, Rockledge, Florida, on the western shore of the Lagoon. These data will ultimately be used to evaluate groundwater seepage. Data collection includes, temperature profiling using temperature stakes and distributed temperature sensing. Temperature stakes consist of 4 to 5 temperature sensors imbedded in 0.6 to 0.9 meter long polyvinyl chloride stakes that are designed to be driven into the sediment at the bottom of the lagoon. Temperature data were collected hourly at a resolution of 0.0625...

The U.S. Geological Survey (USGS) previously identified 62 Principal Aquifers (PAs) in the U.S., with 57 located in the conterminous states. The USGS characterized areas outside of PAs as “other rocks;” other rocks account for about 40% of the area of the conterminous states. This paper subdivides the large area identified as other rocks into Secondary Hydrogeologic Regions (SHRs). SHRs are defined as areas of other rock within which the rocks are of comparable geologic age, lithology, and relationship to the presence or absence of underling PAs or overlying glacial deposits. A total of 69 SHRs were identified. SHRs were identified in two phases. In the first phase, Other Rock Regions (ORRs) were defined as regions...

A soil-water balance model (SWB) was developed to estimate potential recharge and surface runoff for portions of the St. Louis River drainage basin, northeast Minnesota, for the period 1995 through 2010. The model was used in the creation of St. Louis River streamflow distribution maps, as part of the associated report, U.S. Geological Survey Scientific Investigations Map 2017-3390 (http://dx.doi.org/10.3133/SIM20173390). This SWB model was calibrated using three independent hydrograph separation models: PART, Hysep-fixed, and Hysep-sliding method. The basic framework for this model was the statewide Minnesota SWB potential recharge model, described, calibrated, and documented as part of U.S. Geological Survey Scientific...

This dataset contains information on the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system. Data include well identification number, name, latitude, longitude, potential-human-influence category, percent urban and crop land use in a 500 meter radius around each well, and measures of county-based groundwater use and irrigation. Ancillary information includes nearest appropriate streamflow gaging stations and meteorological stations, and also climate division for each well.
