Quality Control In A Water Distribution Network

Abstract
The goal of an early warning water monitoring system (EWWMS) for quality
control in a water distribution network is to identify low probability/high impact
contamination events in source water or distribution systems. It should be able
to detect not only intentional contamination, but also contaminants introduced
accidentally or natural occurrences. Firstly, to ensure the full protection of
drinking water, a technology- based EWWMS should be one component of the
program. While laboratory technology exists to measure a wide range of
contaminants, it’s not the same for on-line and real time technology. A number
of research projects are investigating rapid and on-line monitoring technologies,
including biosensors and biochips, fiber optics and microelectronics. In most
cases the performances of these systems has not been fully characterized. In this
paper, a submergible UV/VIS spectrometer has been extensively tested in
laboratory experiments, with the aim to check its limits of sensitivity, its ability
to identify and quantify specific contaminants and its rate of false
positive/negative.
Keywords: early warning water monitoring system; drinking water distribution
system control; spectroscopy; on-line monitoring, tracer test, contamination.
1 Introduction
The goal of an EWWMS is to identify reliably low probability/high impact
contamination events in source water or distribution systems. Monitoring water
quality in real time allows an effective local response that minimizes the adverse
impacts that may result from the event [1, 14]. Other desirable features of an
EWWMS include: affordable cost, low skill and training, coverage of all
