Emerging Contaminants

By Definition, States Play Catch-Up

Microplastics and perflourinated compounds are two examples of materials detected recently in the environment at concentrations that cause concern.

Such contaminants of emerging concern, also known as emerging contaminants, are new. Consequently they are not commonly monitored or regulated. The related science, standards, and guidance may be thin.

The occurrence, fate, and transport of emerging contaminants is a priority issue for NEIWPCC. The ecological and human health implications of these contaminants for wastewater and drinking water treatment facilities are of key interest.

Media attention and advances in detection techniques have engendered a growing awareness of emerging contaminants. This attention also focuses on the need for action and leadership at the local, state, and regional levels.

One such emerging pollutant is microscopic plastic fibers that enter the environment when polyester fleece is laundered.

Ongoing research focuses on the environmental impacts of these compounds. This work includes the development of better detection and analytical methodologies, source characterization, and human health and ecological impacts.
