Contaminants of Emerging Concern (CECs)

Contaminants of emerging concern (CECs) pose a risk to the water industry due to their presence in sewage and drinking water sources, as well as their potential formation during treatment and their potential toxicity to humans and the environment. A defining feature of a CEC is a lack of knowledge on either occurrence or toxicity (or both), making it difficult to provide an accurate risk assessment, often compounded by a community’s increased need for transparent communication in regard to their own risk perception.
