The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.
The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each fire. Users can select fires by year back to 2013.
This course provides an overview of how groundwater and surface water interact, what the implications of these interactions on water resources are, and how water can be more effectively managed if an understanding of these interactions is incorporated.
The course presenters are Ken Bradbury from the Wisconsin Geological and Natural History Survey, William A. Alley from the National Groundwater Association, and Thomas Harter from the University of California, Davis.
The surge in recent years of earthquake activity associated with some oil and gas operations, most notably in Oklahoma, has spurred a range of actions and responses from state geoscientists and regulators. States have taken measures to monitor these earthquakes and moderate the activities that may be causing them, particularly the deep underground injection of large volumes of wastewater. Many states with extensive oil and gas operations but little or no increased earthquake activity have also adopted practices to prevent and prepare for potential induced earthquakes in their area.
This course provides information about induced seismic activity in the United States, specifically in the mid-continent. It includes information on mitigation planning, the state of seismic monitoring at the state level, and the challenges in communicating the science of the issue to the public and decision-makers.
The course presenters are Bill Ellsworth from the U.S. Geological Survey, Austin Holland from the Oklahoma Geological Survey, and Rex Buchanan from the Kansas Geological Survey.
Flooding is a perennial hazard for rivers and coasts alike. Every year, flooding results in billions of dollars of damage and the loss of dozens to hundreds of lives across the United States. Efforts to mitigate this hazard rely on the work of geoscientists, planners, and communicators to assess and minimize risks, prepare and inform communities, and ensure that lives and livelihoods are prioritized before, during, and after flood events.
The U.S. Environmental Protection Agency (EPA) provides an interactive map of hazardous waste cleanups across the United States. The "Cleanups in My Community" map provides a huge amount of information on thousands of cleanups of many kinds. For every cleanup, users can access and download reports, assessments, compliance actions, and the EPA's assessment of the potential for any contaminated land to be used for renewable energy development.
Groundwater is often a "transboundary" resource, shared by many groups of people across town, county, state, and international boundaries. Changes in groundwater resources can create unique challenges requiring high levels of cooperation and innovation amongst stakeholder groups, from individuals to state and federal government.
The High Plains Aquifer (HPA), which spans eight states from South Dakota to Texas, is overlain by about 20 percent of the nation’s irrigated agricultural land, and provides about 30 percent of the groundwater used for irrigation in the country according to the U.S. Geological Survey. Work by the Kansas Geological Survey indicates that some parts of the aquifer are already effectively exhausted for agricultural purposes; some parts are estimated to have a lifespan of less than 25 years; and other areas remain generally unaffected (Buchanan et al., 2015).
The 2016 Critical Issues Forum was a 1-½ day meeting covering multiple aspects of groundwater depletion in the High Plains. Presentations covered the current state of the High Plains Aquifer and water usage from scientific, legal, regulatory, economic, and social perspectives. State-specific perspectives were provided from Kansas, Nebraska, Texas, and Oklahoma, and a variety of issues were discussed surrounding communication, negotiation, policy, and the influence of climate change. Break-out sessions and participant discussions identified lessons learned and best practices from the High Plains Aquifer experience that might apply to other regions facing changes in the Earth system.
