Fact Sheet
The USEPA published the Water Security
Initiative: Interim Guidance on Planning for
Contamination Warning System Deploy-
ment
in May, 2007. The Interim Guidance
document has been developed to help
drinking water utilities improve their abil-
ity to detect intentional or unintentional
distribution system contamination.
The USEPA purchased 15 of GE Ana-
lytical Instruments’ Sievers 900 On-line
TOC Analyzers for use in the EPA Water
Security Initiative Program, which in-
cludes a pilot study at the City of Cincin-
nati. The City of Cincinnati and the USEPA
have 17 water quality panels deployed
throughout Cincinnati’s distribution sys-
tem. These water quality monitoring
panels include TOC, chlorine, conduc-
tivity, ORP (oxidation reduction poten-
tial), pH, and turbidity. One of the panels
shows the Sievers 900 OL (pictured above) and is also
on the front page of the Interim Guidance document.
The USEPA’s Interim Guidance document has identified
TOC, chlorine, and conductivity as the three most impor-
tant parameters for detecting a contaminant (see Table
4-2 below from the USEPA’s Interim Guidance document).
If a site was to utilize chloramines rather than chlorine in
its disinfection process, chlorine would no longer be an
applicable parameter, making TOC monitoring that much
more critical.
The USEPA will award two applicants (utilities
serving over 750,000 people) the funds to pilot
their own contamination warning system. The
USEPA will then develop and publish a plan to
promote the adoption of drinking water con-
tamination warning systems by drinking water
utilities throughout the United States.
