San Mateo Creek Basin Phase II Site Inspection

The New Mexico Environment Department (NMED) Superfund Oversight Section (SOS) conducted a Phase 2 Site Investigation (SI) of the San Mateo Creek Basin legacy uranium mine and mill site area (Site), which is located in Cibola and McKinley counties, New Mexico. The objective of the SI is to evaluate the site using the Hazard Ranking System and the Superfund Chemical Data Matrix (SCDM) to determine if a threat to human health and the environment exists such that further action is warranted. This SI is considered a Phase 2 as it is a follow up to the Phase 1 SI of June 2010.
