Contaminants of emerging concern definition

Contaminants of emerging concern or "CEC" means substances de­ tected in water that require further study to determine potential im­ pacts to human health and the environment. CEC include, but are not limited to, pharmaceutical products, endocrine disrupting compounds, personal care products, and household cleaning products.

Contaminants of emerging concern or "CEC" means chemicals or compounds not regulated in drinking water, ground- water, surface water, or advanced treated water, some of which may be candidates for future regulation depending on their ecological toxicity, potential human health effects, public perception, and frequency of occurrence.
