WellYield_AncillaryData_NashobaTerrane

This data set contains information on well yield and ancillary information at 7,287 wells in the bedrock aquifer in the Nashoba terrane in central and eastern Massachusetts. Well yield was compiled from records in databases and files of the Massachusetts Department of Environmental Protection and U.S. Geological Survey. Ancillary data include well depth; bedrock geology, surficial geology,...

Simulated Groundwater-Contributing Areas to Selected Streams, Ponds, Coastal Water Bodies, and Production Wells, Plymouth-Carver Region and Cape Cod, Massachusetts

The U.S. Geological Survey (USGS) assisted the Massachusetts Department of Environmental Protection (MassDEP) with the Massachusetts Estuary Project (MEP), by delineating groundwater-contributing areas to various hydrologic features including ponds, streams, and coastal water bodies, throughout southeastern Massachusetts. These contributing areas were delineated over a 6-year period from 2003...

Concentrations of arsenic in water from public-supply and domestic wells in New Hampshire (2004-2006)

Groundwater samples from public and private drinking water wells throughout the state of New Hampshire were analyzed for total Arsenic (As). Samples were collected after pH, specific conductivity, dissolved oxygen, and water temperature had met stabilization criteria as outlined in the USGS National Field Manual (United States Geological Survey 2005).The As analyses were carried out in the...

Lineaments_ShadedDEMs_Coincident_4quads_NashobaTerrane

This data set is line data layer of lineaments delineated in the Ayer, Hudson, Marlborough, and Westford quadrangles from shaded Digital Elevation Model (DEM) data by the U.S. Geological Survey (USGS). The lineaments are used in an analysis of well yield in the Nashoba Bedrock Terrane in central and eastern Massachusetts that is described in USGS Scientific Investigations Report 2012-5155....

Probability of arsenic concentrations greater than 10 micrograms per liter in groundwater used by domestic wells in the United States

Arsenic concentrations from 20,450 domestic wells in the U.S. were used to develop a logistic regression model of the probability of having arsenic > 10 µg/L (“high arsenic”), which is presented at the county, state, and national scales. Variables representing geologic sources, geochemical, hydrologic, and physical features were among the significant...

Data related to the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system

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.

County level domestic well population with arsenic greater than 10 micrograms per liter based on probability estimates for the conterminous U.S.

Approximately 43 million people (about 14 percent of the U.S. population) rely on domestic wells as their source of drinking water. Unlike community water systems, which are regulated by the Safe Drinking Water Act, there is no comprehensive national program to ensure that the water is tested to ensure that is it safe to drink. A study published in 2009 from the National Water-Quality...

Velocity, depth, and selected water quality profiles of the Lower Penobscot River Estuary in Maine, 2017

This data release includes transect data comprising velocity and depths collected by use of an acoustic-doppler current profiler (ADCP), and vertical profile data comprising conductivity, temperature, and depth by use of a conductivity, temperature, and depth (CTD) instrument, as well as tide elevation data at specified locations in the lower Penobscot River and Penobscot Bay (the Penobscot...

Generalized linear models for forecasting the probability of groundwater levels declining below specified low thresholds for selected wells in the conterminous U.S.

This dataset contains *.rdata files that contain model objects returned from the glm{stats} function (v.3.3.0) in R. for 258 models derived for selected wells in the conterminous United States. The models are generalized linear models with a binomial response variable (glm family set to binomial) for forecasting the probability of groundwater levels declining or maintaining below specified low...

Testing data set for independent analysis of New Hampshire arsenic model

This data release contains a table of measured arsenic concentrations and associated model input variables used to test existing multivariate logistic regression models that predict the probabilities of arsenic concentrations exceeding threshold values of 1, 5, and 10 micrograms per liter in bedrock aquifers of New Hampshire. Location data are censored to the county level.
