Emerging Contaminants

USEPA is taking or considering actions to add regulations on several emerging contaminants. An “emerging contaminant” is defined as a chemical or material that is characterized by a perceived, potential, or real threat to human health or the environment or by a lack of published health standards. A compound may also be emerging because a new source or a new pathway to humans has been discovered, or a new detection method or treatment technology has been developed. USEPA maintains a list of emerging compounds that may warrant further possible study and regulation. As new testing of emerging contaminants is required or new rules are promulgated, NKWD may need to adjust treatment or invest in new treatment processes.  NKWD already provides advanced treatment processes including granular activated carbon and ultraviolet light disinfection as part of a multi-barrier approach that is effective in treating broad categories of compounds.²
