Data

This dataset describes the quantity, morphology, and polymer identity of microplastics in the water column and surficial sediments of Milwaukee-Area streams, the Milwaukee Harbor, and Lake Michigan (Wisconsin). Water samples were collected at 10 locations, 2-4 times each, from May to September, 2016. At the 4 shallowest locations, water was collected only at the water surface. At the...

Selenium loads have been increasing over time in the Elk River, British Columbia, Canada, due to coal mining operations and runoff from associate spoil piles. The Elk River is a tributary to the Kootenay/Kootenai River and Lake Koocanusa. Extensive fish tissue monitoring has been conducted in Lake Koocanusa to assess the potential impacts of selenium from the Elk River (http://deq.mt.gov...

The U.S. Geological Survey (USGS) developed a spatial water-quality model called SPAtially Referenced Regressions On Watershed attributes (SPARROW) to estimate the major sources and environmental factors that affect the long-term supply, transport, and fate of contaminants in the Nation's streams. The SPARROW model relates in-stream water-quality data to spatially referenced...

Groundwater is an important source of drinking and irrigation water throughout Idaho, and groundwater quality is monitored by various Federal, State, and local agencies. The historical, multi-agency records of groundwater quality include a valuable dataset that has yet to be compiled or analyzed on a statewide level. The purpose of this study is to combine groundwater-quality data from...

To begin filling data gaps for development of a Treasure Valley groundwater-flow model, we installed 10 new real-time streamgages on drains along the lower Boise River from Eagle to Parma. The streamgages will monitor the amount of shallow groundwater the aquifer system discharges to surface water. This was a missing component in previously developed models.

The Real Time Groundwater Level Network contains water levels and well information from wells with "real time" data transmission instrumentation.

The Active Groundwater Level Network contains water levels and well information for wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months.

The USGS maintains a network of wells to monitor the effects of droughts and other climate variability on groundwater levels.

The Active Springs Monitoring Sites Network provide data from springs in the active measurement program of the U.S. Geological Survey

Scouring of streambed material surrounding bridge structures is a leading cause of bridge failure in the United States. Damages resulting from bridge failure oftentimes lead to financial burdens and loss of life. To date, there has been no comprehensive evaluation of the current (2016) effectiveness of the guidance or overall long-term performance of bridge-scour countermeasures provided...
