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.
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.
This course is intended for geologists involved in Light Non-Aqueous Phase Liquid (LNAPL) assessment and remediation. Roger Lamb, the course presenter, 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.
Geoscience is essential to our understanding and management of produced water, an inevitable byproduct of oil and gas development. This course provides a scientific and regulatory background of produced water, how it is commonly disposed, what opportunities exist for the re-use of produced water, and what the environmental and regulatory challenges for re-using produced waters are.
Fresh water is an increasingly scarce resource in an increasingly populous and water-intensive world. Maintaining an adequate supply of fresh water both nationally and globally will be one of the largest challenges of the 21st century. Desalination of salty water – from both the ocean and the ground – represents a huge potential source of fresh water. The development of this resource requires a combination of geoscience, engineering, waste management, policy, and community outreach and participation.
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. Roger Lamb, 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.
