Factors:•Total reliance on groundwater•Growth & increasing water consumption•Lack of infrastructure & alternate supply•Contamination risks•Sensitive natural areas
BACOG Water Resources InitiativeBarrington Area Council of Governments
Basic Questions:
•Where Is the Water?•How Much Water Is There?• Is the Supply Sustainable?•What is the Water Quality?
The BACOG Approach
DATA
The BACOG model incorporates over 25,000 wells with more than 110,000 lines of soil descriptions.

The BACOG Approach
The BACOG approach processes all available data into hydraulic conductivity values based on soil descriptions.
The BACOG Approach
The hydraulic conductivities are interpolated for areas between data points and bedrock and surface topographies are incorporated.
MAPPING & VISUALIZATION
APPLICATIONS
