Groundwater Mapping: Importance and Overview

 

Vermont remains without a comprehensive map of the state’s groundwater resources. That means Vermont has no clear understanding of where this invaluable resource is and, as such, might have difficulty in managing and protecting it for the long-term.

In 2008, however, VNRC successfully secured an appropriation from the Legislature to support the Agency of Natural Resources in their effort to begin to map the resources. It was a strong step forward, yet more funding is necessary to finalize this important process and create a comprehensive overview of the state”s underground water resources.

A recent article, written by Eric Hanson, Source Protection Specialist with the Vermont Rural Water Association, explains the process of groundwater mapping in a bit more detail, including opportunities to help foster groundwater mapping in your town. As Mr. Hanson explains, groundwater mapping in Vermont is complex due to our geology.  Many people expect one simple map, when in reality this type of map isn’t available.  Instead, layers of maps are interpreted to provide all kinds of different information on our groundwater.

This excellent article describes the process well. In the end, a comprehensive set of maps of Vermont’s groundater – two thirds of the state’s drinking water supply – will help ensure the state manages and maintains the quality and quantity of this invaluable resource now and for future generations.
