This map integrates well-drilling data with surficial geologic mapping and bedrock geology to produce a true three-dimensional model of the subsurface conditions within the Marlborough quadrangle, Massachusetts. The first component of this model is a map depicting a three-dimensional block diagram of the stratigraphic units that overlie the bedrock surface. The map also presents three-dimensional depictions of the individual stratigraphic units, their aerial extent and volumes.

In addition to the map, the supporting grid files, database and documentation for the three-dimensional model are provided.

This three-dimensional model of the subsurface stratigraphy of the Marlborough quadrangle provides a tool to visualize and explore the relationships of the subsurface units to one another, to the underlying bedrock, and to the water bearing fractures within the bedrock.

There are three immediate benefits of this three-dimensional model:

  1. it provides a better estimate of the volume of sand and gravel resources, surpassing current assessments it affords an estimate of the volume of water available in storage, making it a more complete measure of our water assets.
  2. it includes grid files of each stratigraphic unit, which provides a better initial conceptual model of the aquifer systems. The consulting community and water managers can import these grid files into groundwater modeling software for numerical analysis. In addition, the three-dimensional model can better delineate ground water flows, areas of groundwater recharge, and aquifer interconnectedness.
  3. It will also help identify possible contaminant pathways and assist in the placement of ground water monitoring wells. The model can also be used to assist with the planning of major construction projects, assess the impacts from development, provide guidance for land use planning and smart growth initiatives. In total, a three-dimensional model of the subsurface provides critical geologic information for natural resource decision making.

The mud quickly clogged culverts under Wapping Road, Route 5/10, and the Pan Am Southern Railway tracks, partially filled in wetlands on both sides of Route 5/10, and partially filled in drainage ditches upgradient of these wetlands. This resulted in localized flooding of property along the east side of Route 5/10. Prepared for the Deerfield Board of Selectman and Board of Public Health 19 pages.

The purpose of the visit was to: 1) identify the type of slides that occurred; 2) estimate the dimensions and volume of material moved; 2) estimate the geological and environmental conditions leading to the slope failures; and, 4) determine the propensity for future occurrence. Four landslides were observed. Slide 1 is immediately east of the confluence of Trout Brook with the Cold River and Slides 2, 3, and 4 are clustered together on a north- facing slope about 1850 feet east of the confluence of Black Brook with the Cold River.
