The Goo Is Going!
Money Point Sediment RemediationSource of Goo – Historic operations at former creosote plants.
Contaminant (Goo) – Creosote used to treat lumber and piles.
Environmental Impact – Toxic to fish and marine life.
Solution – Dredge “hot spots,” apply clean backfill and enhance shallow
areas with wetland grasses and oyster reef (“Living Cap”).
Phase 1 – Dredge 800 cubic-yard southern hot spot and begin Living Cap.
Phase 2 – Dredge northern hot spots (80,000 cubic yards); complete Living
Cap, adding oyster shell and clean sand.
Benefits – 19 acres of virtually dead river bottom recovers ecosystem
function. Cancer reduced in bottom fish. Economic marketability improves.
Living Cap will feature 3.5 acres of clean sand bottom, 3.3 acres of
new oyster reef and 1.5 acres of new tidal marsh (total, 8.3 acres).
