This powerpoint presentation begins by providing a brief overview of the water system of
Thomson, Georgia, and McDuffie County. Issues and challenges include the following:
failure to comply with Stage 1 Disinfection Byproducts
Rule;
failure to meet limits for Disinfection Byproducts
Rule (TTHM and HAA5) in Distribution System;
failure to meet Total Organic Carbon (TOC)
Reduction Requirement at Big Creek WTP;
Disinfection Byproducts; and,
formed by reaction between chlorine disinfectants
and naturally occurring organic matter in surface
water. Strategies included:
carbon reduction in the plant filtered water;
improve coagulation/filtration;
oxidant addition;
additional treatment technologies;
carbon reduction in the distribution system;
identified areas of inadequate water use, including
flushing at low flow and
chlorine booster where appropriate;
reduced chlorine demand in system including
unidirectional flushing
and use of alternative disinfectant that requires less
chlorine. Presentation results indicate that:
distribution system improvements were in place;
not enough DBP reduction;
plants have been optimized to the maximum using
conventional water treatment;
not enough DBP reduction;
additional treatment would be necessary to meet the
Stage 1 DBP Rule; and,
pilot testing evaluation showed GAC capable of high
degrees of TOC removal and favorable operational
costs. Includes figures.
