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.
