Inventory of water-quality and geologic-setting data from 674 private wells in Connecticut, 2013-2015

This dataset contains the water-quality results from the testing of unfiltered water samples (environmental samples) collected from 674 private wells in Connecticut for the analysis of arsenic and (or) uranium, using EPA method 200.8. All of the environmental water-quality data and georeferenced locations of the sampled wells were provided by the Connecticut Department of Public Health

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 sp

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

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 Ass

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 pr

Streamflow and total phosphorus and orthophosphate data for samples collected in and near the Assabet River, Massachusetts, October 2008 through April 2014

Streamflow and phosphorus concentrations were monitored in the Assabet River in central Massachusetts in order to evaluate concentrations and loads in the river before, during, and after changes in the amount of total phosphorus that was discharged to the river from three wastewater-treatment plants. At four locations the U.S. Geological Survey collected weekly flow-proportional, composite
