An
Integrated Water Quality Security System for Emergency Response
Rakesh
Bahadur1 and William Samuels2
This
paper describes an integrated approach for water quality security that involves
every component of a water supply system (raw water sources, intakes, treatment
plants, pipeline network). The Integrated Water Quality Security System (IWQSS) consists of the
following three components, which operate from the same platform, ArcView, a
geographic information system developed by the Environmental Systems Research
Institute (ESRI).
.
·
RiverSpill
(Samuels et al, 2001) – tracks, in real-time, the fate and transport of
contaminants in surface waters
·
Water
Treatment Process (WTP) – simulates the water treatment process component by
removing any contaminants as per the treatment processes.
·
PipelineNet
(Bahadur et al, 2001a, 2001b) – tracks contaminants within the water
distribution system (pipeline network). It can track both, end of pipe
contaminants from the water treatment plant and contaminants introduced after
water treatment.
The
IWQSS allows the user to:
·
Select
a location on a river to introduce a chemical or biological contaminant
·
Track
the contaminant downstream, under real-time flow conditions, to an intake.
·
Further
track the contaminant to a water treatment plant.
·
Simulate
the effectiveness of water treatment processes on the contaminant
·
Mode
the transport of the contaminant through a water distribution system.
·
Identify
the overall population served by the plant and infrastructure impacted.
The
integrated system can comprehensively study all the components of the water
supply. The IWQSS can track contaminants introduced anywhere in the system:
·
Upstream
of the intake of a water supply system;
·
At
the water intake or the treatment plant;
·
At
a service reservoir;
·
At
a point in the distribution system;
·
Individual
house connection
