approaches to thoroughly evaluate the
benefits and costs of multiple barriers
used to ensure distribution system water
quality. New approaches for measuring
distribution system integrity will be
carefully evaluated. This work will enable
water utilities to quantitatively evaluate the
value of different barrier approaches, and
institute measurement programs that will
substantially increase the ability of utilities
to measure the health of their system.
utilities meet these challenges. Close
coordination between the Expert Panel
and the planning committees for the other
programs ensures that the DSWQ initiative
and other programs are well integrated.
Where projects of direct value to the
DSWQ SI are identified and funded by
other Foundation research programs, the
knowledge generated in these projects will
be incorporated into the DSWQ SI.
Goal 3: Chloramines—
Filling in the Gaps
For a variety of reasons,
the use of chloramines as a
secondary disinfectant by
U.S. drinking water utilities
has been increasing, and
this trend is expected to
continue. Although the
use of chloramines for
has already been studied
knowledge gaps remain.
The DSWQ strategic initiative will develop
additional guidance and understanding to
help address these gaps.
While these three objectives may first
appear to be separate and distinct, they are
in fact closely related and complementary.
Thus, a particular project funded under the
strategic initiative may be relevant to one,
two, or all three of these objectives.
Integration with Other Research Programs
While the DSWQ strategic initiative
represents a commitment to solve several
key DSWQ issues, it does not address the
full breadth of utilities’ DSWQ challenges.
DSWQ-related research will continue
under the Foundation’s other research
programs—Solicited, Unsolicited, Tailored
Collaboration, and Partnership—to help
