Techniques for Developing High Resolution LNAPL Conceptual Site Models

This course is intended for geologists involved in Light Non-Aqueous Phase Liquid (LNAPL) assessment and remediation. This course provides information on the development of high resolution conceptual site models that can be used to guarantee the project goals are met. The class will cover advantages of a high resolution LNAPL Conceptual Site Model (LCSM); design and implementation of a high resolution investigation field program; case studies and end uses of a high resolution LCSM.

The course presenter is Roger Lamb.

State Responses to Induced Earthquakes

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.

Planning for Coastal Storm and Erosion Hazards

Coastal hazards are a widespread challenge that cost millions (and sometimes billions) of dollars in the U.S. every year due to property loss and spending on mitigation measures. Based on the most recent U.S. Census, over 39% of the U.S. population lives in areas that may undergo significant coastal flooding during a 100-year flood event. Additionally, six of the ten most expensive weather-related disasters in U.S. history have been caused by coastal storms.

Induced Seismicity in the Mid-Continent

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.

Converting Membrane Interface Probe Sensor Results into VOC NAPL Distribution Information

This course will focus on how to use Membrane Interface Probe sensor results in combination with soil and groundwater analytical results to map the distribution of volatile organic chemical non aqueous phase liquids. This course covers guidelines for using direct sensing tools such as the MIHPT system, best practices for collecting and analyzing soil and groundwater samples, and gives examples from case studies on how to combine direct sensing data with analytical results to estimate NAPL distribution.

Assessing, Mitigating, and Communicating Flood Risk

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.

Congress ends session by passing tax reform and continuing federal funding into January, but delays disaster aid

House chamber

On December 22, President Donald Trump signed into law a bill to provide for tax reform and legislation to continue funding the federal government under fiscal year (FY) 2017 levels through January 19. Lawmakers from various states impacted by hurricanes and wildfires this year were seeking billions more in disaster aid funding, but Congress stopped short of sending an $81 billion relief package to the President before the end of the year. 

Interactive map of hazardous waste cleanups in the United States

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.

Interactive map of spills in South Dakota

The South Dakota Department of Environment & Natural Resources provides an interactive map of reported spills in the state (yellow triangles in picture above). Spills are reported for hazardous or environmentally harmful materials such as oil, gasoline, pesticides, solvents, acids, and other industrial chemicals. Spill information is provided from the early 1970s to the present and include information on the source, material, location, and date of the spill.
