In Oklahoma, the Seaway passes through Lincoln, Pottawatomie, Seminole, Pontotoc, Johnston, and Bryan counties.

In Texas, Seaway passes through the following 16 Texas counties: Grayson, Collin, Rockwall, Kaufman, Henderson, Navarro, Freestone, Leon, Madison, Grimes, Waller, Harris, Fort Bend, Brazoria, with terminal segments to Chambers and Jefferson counties.

Seven of these counties (highlighted above) are within the purview of the Region C Regional Water Planning Group. Region C is responsible for water planning in the DFW area.

At least three aquifers are crossed by the pipeline to its refinery destination: the Trinity, Carrizo Wilcox and the Gulf Coast.

The Trinity is a major aquifer for DFW water supplies. [1]

Water is not the sole risk for counties. Counties are having to resort to lawsuits to recover expenses for repairing roads that were damaged as the result of pipeline construction. [2]
