This powerpoint presentation begins by stating the drivers behind this research that include: distribution systems identified as major
security challenge by AWWA;
drinking water remains a relatively simple
target for dissemination of biothreat agents; and,
disinfection data is needed to assist response
and remediation efforts. Topics covered by the presentation include: efficacy of chlorine and
monochloramine -- planktonic testing;
persistence of Bacillus anthracis spores
in a model biofilm;
efficacy of chlorine and chloramine --
spores associated with a model drinking
water biofilm;
ultraviolet possibilities; and,
future research needs. Presentation conclusions indicate that: spores will persist on surface with biofilm (>42 days);
uncertain if growth occurring within biofilm; even an immature biofilm can decrease disinfectant
efficacy 3 to 5 fold; and,
CT values may need to be re-visited to consider biofilm
shedding and spore clumping
(are planktonic cells truly planktonic?). Includes tables, figures.
