Southern Rhode Island & Eastern Connecticut

Where Harborline works.

From Kent County south through South County, across the Pawcatuck and into New London County. It’s a small territory on purpose — close enough that we can actually get back to you, and small enough that we know what the water does here.

Reservoir-fed municipal systems along the coast, bedrock wells inland, and two states’ worth of different testing guidance. The water here is genuinely not the same as the water twenty miles north.
