Hartford Basin Deep Fossil Aquifer — Central Connecticut

Hartford, Connecticut, USA

Deep Triassic-Jurassic Hartford Basin in central Connecticut. The deepest bedrock wells access fossil water trapped in Mesozoic rift basin sediments for over 150 million years. While shallow fracture zones receive modern recharge, the deep confined Portland and New Haven formations contain ancient water with elevated temperature.

Water Rights

Riparian Rights

Tied to land adjacent to water

Landowners with property bordering a watercourse have the right to reasonable use of the water. Rights are inseparable from the land itself.

  • Attached to land with water frontage
  • Cannot be sold separately from the land
  • Subject to "reasonable use" doctrine
  • Shared equitably among riparian owners
Common in eastern US states where water is historically abundant• Asset location: Connecticut
