Understanding this Superfund site

Prewitt Abandoned Refinery is a federal Superfund site in New Mexico.

Current status: Construction complete. Physical construction of the cleanup remedy is complete, though long-term monitoring and institutional controls typically continue for years or decades. Groundwater treatment systems, for example, often run long after surface cleanup finishes.
