Microplastics data collected from streams in the northeastern United States, 2017-2018

These data were collected to characterize the quantity and quality of microplastic particles found in 17 streams in the northeastern United States, from New York to Virginia. USGS staff who represent the Urban Landscapes Capabilities Team (ULCT) within the North Atlantic-Appalachian Region designed the study and collected the water samples on which the data are based. Data were collected

Basin characteristics and point locations of road crossings in Connecticut, Massachusetts, and Rhode Island for highway-runoff mitigation analyses using the Stochastic Empirical Loading and Dilution Model

This data release documents the location of intersections between roads and streams, referred to as road crossings, and associated basin characteristics to support highway-runoff mitigation analyses using the Stochastic Empirical Loading and Dilution Model (SELDM, Granato, 2013) in Connecticut, Massachusetts, and Rhode Island. The data set of road crossings was generated from the

Data associated with the evaluation of the PAT (Purge Analyzer Tool), Stringfellow Superfund site, Jurupa Valley, California, 2017

Data presented here were collected in support of analyzing the analytical model PAT (Purge Analyzer Tool). There are manual measurements of well construction, hydraulic, and chemical data for several wells from the Stringfellow Superfund site, Jurupa Valley, California. The hydraulic data includes hydraulic head. Chemical data includes physiocochemical data.

Soil Frost at Sleepers River Research Watershed, Danville, Vermont

Soil frost measurements have been made at Sleepers River Research Watershed starting in 1983. Measurements were made by U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory from 1983 to 1993, followed by the U.S. Geological Survey from 1993 to the present. Measurements started at 5 sites and has increased to 10 sites. Sites range in elevation from 225 to 670 meters and...

Borehole, Surface, and Water-Borne Geophysical Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018

From October 2016 to July 2018, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and Maine Department of Transportation, collected surface, marine and borehole geophysical surveys to characterize the subsurface materials on land and under the water at a former mine facility in Brooksville, Maine. Three water-based geophysical methods were used to evaluate

Electrical Resistivity Tomography (ERT) Surveys at the Callahan Mine Superfund Site in Brooksville, Maine: May 2017

On May 10, 2017 an electrical resistivity tomography (ERT) profile was collected on the land along the gravel path between the water and the slime impoundment associated with the former mine activities. A total of 56 electrodes, spaced 1 m apart, extended along the base of the slope. Electrode 1 was near monitoring well MW-701 and electrode 56 was near MW-702. In the ERT measurement c

Continuous Resistivity Profiling (CRP) at Callahan Mine Site: May 2017 to July 2018

In May 2017 and July 2018, continuous resistivity profiling (CRP) surveys were collected in Goose Pond at the Callahan Mine site. CRP methods were used to characterize the resistivity of the water column and subbottom layers. For this investigation, 11 electrodes spaced 10 m apart and mounted in a streamer were towed behind the boat. The first two electrodes, closest to the boat, we

Stage Measurements of Goose Pond at Callahan Mine Site: May 2017 to July 2018

Water levels in Goose Pond were collected while collecting geophysical surveys in May 2017. Three transducers were set to monitor the change in water level associated with tidal changes.

Electromagnetic Induction, Gamma and Fluid Logs from Shallow Boreholes at the Callahan Mine Site: May 2017

From October 2016 to July 2018, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and Maine Department of Transportation, collected surface, marine and borehole geophysical surveys to characterize the subsurface materials on land and under the water at a former mine facility in Brooksville, Maine. Borehole geophysical logs were collected in five boreholes

Continuous Seismic Profiling (CSP) at Callahan Mine Site: May 2017 to July 2018

In May 2017 and July 2018, continuous seismic profiling (CSP) surveys were collected in Goose Pond at the Callahan Mine site. The chirp frequency CSP tool was used in the deep water. A tuned transducer (dual-echo sounder) was used in the shallow water, and the data are served separately but within this data release (See CSP-DSO). CSP methods use an acoustic sound source that trave

Shear-Wave and Compression-Wave Active Seismic at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018

On May 10, 2017 a land-based seismic survey was collected to obtain a shear- wave velocity (Vs) and compressional velocity (Vp). The Vs was used for estimating with the HVSR data to determine the depth to rock. A secondary objective was to obtain Vs and Vp measurements of the overburden sediments at the toe of the impoundment and adjacent to the stream for geotechnical applications.
