This powerpoint presentation begins by providing a brief overview of outbreaks caused by distribution system deficiencies and epidemiological studies by Payment et al., in 1991 and 1997. The impact of Payment's studies is presented, along with applying the QMRA model to distribution systems. Presentation conclusions: the first step of QMRA intrusion modeling
is to establish the duration, frequency
and intensity of ingress to determine
realistic ingress distributions;
must address this first task before any
mechanistic modeling;
still considerable amount of work to be
done;
unsolved issues about base QMRA
modeling;
significant limitations in predicting
intrusion volumes; and,
non-mechanistic modeling is not
hindered by these issues but has other
limitations such as pathogen/indicator
relationships. Includes figures.
