This powerpoint presentation begins by presenting the research objective: to determine if the levels of earthy
and musty odors in various
waters are dependent on the
background water matrix and/or
the presence of chlorine or
chloramines. The experimental design included the following:
6 water sources;
16 water samples by 8 different protocols =
128 FPA analyses;
used Flavor Panel Analysis to detect odors
Chlorine, Earthy, Musty and Earthy/Musty; and,
Experimental Factors included
dechlorination (Treatment),
MIB contaminant addition, and
Geosmin contaminant addition. A statistical model is presented, along with fixed effects for: total chlorine odor; Earthy Odor - (Geosmin = 20.1 - 61.9 ng/L); Musty Odor (MIB = 18.6 ng/L); (Geosmin= 20.1-61.9 ng/L) & (MIB = 18.6)
ng/L) - (MIB = Musty Odor). Conclusions indicate that: there are significant statistical results
showing MASKING of Earthy Odors
between Chlorine and Geosmin at drinking
water levels (20.1 - 61.9ng/L);
Chlorine hides the earthy odor.
masking of Musty Odors were not
significant with this experimental
design at drinking water levels (18.6 ng/L); and,
use other measurements of odor panel
evaluation that have less errors of analysis. Includes tables, figures.
