Emerging contaminants definition

Emerging contaminants means emerging contaminants as defined in the “Technical Fact Sheets about Contaminants of Concern at Federal Facilities”, available at: www.epa.gov/fedfac/emerging-contaminants-and-federal-facility-contaminants-concern.

Emerging contaminants means a chemical or material characterized by a perceived, potential, or real threat to human health or the environment or by a lack of published health standards. A contaminant also may be "emerging" because of the discovery of a new source or a new pathway to humans.

Emerging contaminants means emerging contaminants as referenced at: Emerging Contaminants and Federal Facility Contaminants of Concern | Cleanups at Federal Facilities | US EPA or any other contaminant classified as emerging by the Commissioner.
