Emerging Contaminants

As technology continues to evolve and improve, laboratories are able to identify and detect new compounds that were previously unknown. When found in the drinking water supply, these new chemicals are known as “emerging contaminants”. Emerging contaminants create a challenge for drinking water providers because they are unregulated and very little is known about their potential risks to human health and the environment.

EMERGING CONTAMINANTS TIMELINE

THIS TIMELINE PROVIDES AN INTRODUCTION TO THE ISSUE OF EMERGING CONTAMINANTS IN THE CAPE FEAR REGION. AS OUR WORK PROGRESSES IN ADDRESSING THIS CHALLENGE, WE WILL CONTINUE TO ADD NEW INFORMATION.
