The Delaware Geological Survey provides an interactive map with a large amount of information about groundwater in the state, including:

• Groundwater recharge potential
• Depth to water under wet, normal, and dry conditions
• Water table elevation under wet, normal, and dry conditions
• Unconfined aquifer base elevation, thickness, and transmissivity (Sussex County only)

The interactive map also includes a partial map of the surface geology in the state.
