Geology & Depth
Connecticut's bedrock consists primarily of crystalline metamorphic and igneous rock — gneiss, schist, and granite — which yields water through fracture zones. The Connecticut River Valley has a narrow band of sedimentary sandstone and brownstone with more predictable yields.
Most residential wells in Connecticut are drilled to 250 feet, with a typical range of 80–600 feet. Water table depth: 50-200 feet in stratified drift deposits; 100-500 feet in bedrock wells.
Permits & Licensing
All water well drillers must be registered with the Connecticut Department of Consumer Protection. Homeowner drilling is not permitted.
Permit authority: Local Health Departments issue well permits under Connecticut Department of Public Health regulations. Expect $100-$400 in permit fees.
Primary Aquifer
Crystalline Bedrock Aquifers / Connecticut Valley Stratified Drift Aquifers. About 23% of Connecticut residents rely on private wells, particularly in rural Litchfield County and eastern Connecticut.
Best drilling months: April through November; frozen ground and snow cover limit winter drilling access.
Common Water Quality Concerns
Connecticut well water commonly contains: radon, arsenic, uranium, iron, manganese, coliform bacteria. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
