The U.S. Environmental Protection Agency developed a conceptual design for a contamination
warning system (CWS) in close partnership with drinking water utilities and other key
stakeholders in response to Homeland Security Presidential Directive 9. Requirements of an
effective CWS include coverage of a broad number of potential contaminants, coverage of the
entire distribution system, timely detection, reliable indication of contamination, and
sustainability through dual-use application. Modeling and analysis indicates that a CWS design
that integrates the following common monitoring and surveillance strategies should meet all of
these requirements satisfactorily. The common monitoring and surveillance strategies include:
online water quality monitoring;
routine and triggered sampling and laboratory analysis;
enhanced security monitoring;
consumer complaint surveillance; and,
public health surveillance. Includes tables, figures.
