Land-Based Frequency Domain Electromagnetic Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to May 2017

In October 2016 and May 2017 frequency domain electromagnetic (FDEM) methods were used to image the electrical conductivity of the shallow subsurface. Electrical conductivity can be caused by changes in the soil, overburden, saturation, and water quality. Two multi-frequency tools were used at the site. One of the tools has a 1.6-meter (m) long antenna that was used in the verti

Continuous Seismic Profiling with a Dual-Frequency Echo Sounder (CSP-DSO) at Callahan Mine Site: May 2017

In May 2017 a dual-frequency echo sounder was used in Goose Pond at the former Callahan Mine site to obtain seismic profiles in very shallow water. The method uses two fixed transducers mounted in the same housing. One transducer was 24 kiloHertz (kHz) and the other was 200 kHz. The CSP-DSO data were collected concurrently with continuous resistivity profiling data, and the water bottom was...

Horizontal-to-Vertical Spectral Ratio (HVSR) Passive Seismic at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018

The horizontal-to-vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three-component seismometer to measure the vertical and horizontal components of ambient seismic noise. Seismic noise in the range of ~0.1 to 1 Hertz (Hz) is caused by ocean waves, large regional storms, and tectonic sources. A resonance frequency (f0) is induced in the unconsolida

Field blank and field replicate datasets for inorganic and organic compounds collected for the National Water Quality Network, water years 2013-17

The U.S. Geological Survey (USGS) National Water Quality Network - Rivers and Streams (NWQN) comprises 117 surface-water monitoring sites designed to track ambient water-quality conditions across the nation. This dataset includes field quality-control results (field blank and field replicate concentrations), along with the water-quality result of each associated surface-water sample

Tidal Daily Discharge and Quality Assurance Data Supporting an Assessment of Water Quality and Discharge in the Herring River, Wellfleet, Massachusetts, November 2015–September 2017

This data release provides data in support of an assessment of water quality and discharge in the Herring River at the Chequessett Neck Road dike in Wellfleet, Massachusetts, from November 2015 to September 2017. The assessment was a cooperative project among the U.S. Geological Survey, National Park Service, Cape Cod National Seashore, and the Friends of Herring River to characterize e

Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016

This data release contains trend results computed on the basis of modeled and observed daily streamflows at 502 reference gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio %2

Model archive for analysis of the effects of impervious cover on receiving-water quality with the Stochastic Empirical Loading Dilution Model (SELDM)

This is a model archive of SELDM development data and simulation results of total phosphorus concentrations in concurrent stormflows from drainage basins in the Northeastern U.S. with varying levels of imperviousness. Model development files include details of simulated hydrology, basin properties, upstream undeveloped area water quality, and developed area (impervious area) runoff qual

Domestic Wells in the United States

Domestic wells provide drinking water supply for approximately 40 million people in the United States. Knowing the location of these wells, and the populations they serve, is important for identifying heavily used aquifers, locations susceptible to contamination, and populations potentially impacted by poor-quality groundwater.

Concentrations of metals and other water-quality data for the Assabet and Concord Rivers, Massachusetts, 2008

This dataset contains water-quality data for stream samples collected by the U.S. Geological Survey at 12 sites on the Assabet and Concord Rivers in eastern Massachusetts in 2008. The samples were collected monthly from June to October, 2008. The water-quality parameters and constituents include field parameters (water temperature, specific conductance, pH, and dissolved oxygen), co

Discrete water-quality data supporting Herring River restoration project, Cape Cod National Seashore, 1984-2017

Staff from the Cape Cod National Seashore, National Park Service (CACO NPS) began limited water-quality data collection in the Herring River Estuary as early as 1984. In 2006 a monthly sampling program was established for 14 sites to monitor nutrient concentrations, dissolved oxygen, and other constituents. This monitoring program is ongoing and has been supplemented with data from othe

Data on well characteristics and well-pair characteristics for estimating high groundwater levels in selected areas of Massachusetts

A method to estimate the probable high groundwater level in Massachusetts, excluding Cape Cod and the Islands was developed in 1981. The method, commonly called the “Frimpter Method,” uses a groundwater measurement from a test site, groundwater measurements from an index well, and a distribution of high groundwater levels from wells in similar geologic and topographic se
