This powerpoint presentation begins by listing sites of vulnerability that include:
source water;
reservoirs;
treatment plants;
finished water holding tanks; and,
distribution system. The Event Monitor analyzes plant
data, alarms on significant
deviations from baseline, reports
the Event Name if found, and
learns the event fingerprint if not
already in the Plant Event Library. Broad Spectrum Analysis is the key to detecting significant events whether they are
anticipated or not. A two-step patented process is used.
Trigger when deviations indicate agent or
event. Classify agent or event in response
to Trigger. During normal operation, process deviations are not larger than 1 on the
trigger vector derived from grouped variations from baseline operation. The
5 parameters condensed into a single signal become easy to interpret. Process variations grow quickly when a significant amount of
contaminant is present. Agent Library provided by Hach. Currently has
over 30 key agents. More will be added in the
future. Plant Library learned on site for each
location. The Agent Library is searched first then
the Plant Library. If no matches are found an
unknown alarm is reported. The presentation provides a case study on a collaborative project between the U.S. Geological Survey and several local utilities that uses this same work approach for source water.
