5 New Geological Maps Released to Help State Manage Natural Resources

Vermont Business Magazine The Vermont Geological Survey (VGS) has released five new geological maps to help address issues such as groundwater contamination, landslide hazards and geological resource planning. The new surface geology maps show the types of glacial and other unconsolidated materials above the state’s bedrock, such as clay, sand, gravel and till.

“Our state is well known for its strong environmental programs and careful, planned growth. We focus on proactive assistance, planning and protection rather than after-the-fact cleanup and solutions,” said John Beling, Commissioner of the Department of Environmental Conservation. “We strive to make it easier for people in Vermont to find and view new information such as geological maps. With new information, we can better balance the impact of human activity with environmental protection.

Each year, the VGS (bit.ly/VT-VGS) works with universities to release new maps of Vermont cities, watersheds, and areas called quadrangles. This year, the VGS worked with George Springston from Norwich University and Stephen Wright from the University of Vermont.

Together the group mapped the quadrangles of Woodsville, Barnet, Lincoln, Mount Ellen and Brookfield. The quadrilaterals are in an area of ​​more than 1,600 square miles called the Montpellier “one-degree sheet” or 1-D sheet. From 2022 to 2024, the VGS plans to map the rest of the areas in the Montpellier 1-D sheet. Then the VGS can compile all areas into the state’s first complete, transparent, high-resolution 1D map.

“This comes at a time when our country and our state are heavily infrastructure-driven,” said state geologist Ben DeJong. “All of our infrastructure is built on and depends on the geological setting. Through targeted geological mapping, we can ensure a safer and more sustainable built environment. In addition, we can better define the resources we have and provide the information needed to assess environmental and geological risks. »

City planners, scientists, consultants, educators, industry professionals, and members of the public can use geological maps to address scientific or societal questions. For example, urban planners use geological maps to solve problems such as water supply and sewage in areas with high population growth and dense development. Consultants use maps to determine the transport, fate and impact of spilled contaminants such as motor oils. Landowners can use maps to learn about the type and source of materials on their properties, assess hazards like unstable slopes, and better understand their groundwater resources.

Members of the public can find all VGS maps online (bit.ly/VGS-Maps) or request hard copies. They can also view maps categorized by city (bit.ly/VGS-Town-Maps) or learn about the many uses of maps (bit.ly/Map-Uses).

The US Geological Survey funds the VGS mapping program through STATEMAP, a competitive annual grant through the National Cooperative Geologic Mapping Program. The VGS has received this funding for each of the past 25 years.
