Non-Regulated Contaminants Emerging Research, Existing and Future Pollutants in Water Supplies: Old Pollutants, New Concerns New Pollutants, Unknown Issues

Abstract:Those chemical pollutants that are regulated under various international, federal, and state programs represent but a small fraction of the universe of chemicals that occur in the environment as a result of both natural processes and human influence. Although this galaxy of targeted chemicals might be minuscule compared with the universe of both known and yet-to-be identified chemicals, an implicit assumption is that these selective lists of chemicals are responsible for the most significant share of risk with respect to environmental or economic impairment or to human health.

This presentation examines the less-discussed aspects of the background and assumptions that underlie society's "relationship" with chemical pollutants in water. The major intent of this synopsis. is to open some windows onto the landscape of resources (all conveniently accessible via the Internet) for pursuing the many and disparate aspects of "emerging" research regarding water pollutants. A wide spectrum of research needs and gaps has been compiled for a particularly diverse array of water pollutants here: httQ://www.eQa.gov/nerlesdl/chemistrx/Qharma/needs.htm/; in general, these needs and gaps are equally pertinent to most water pollutants.

Briefly summarized are some of the many, disparate issues that require consideration in assessing the challenges in ensuring public health with regard to the use of water. The sections that follow are pertinent to answering questions such as: What types of "new" chemical stressors can be anticipated in water? How important are these stressors to human health? What research gaps might hamper the safeguarding of public health? What disconnects might exist between policy and science?
