Description:
Until recently most interest in drinking water quality has been in the finished water as it leaves the treatment plant. he Safe Drinking Water requires that MCLs be met at the consumers tap. ecause finished water may undergo substantial changes while being transported through the distribution system to, the consumer, interest has increased on the effect the system itself may have on water quality. his paper reports on a study that was conducted in cooperation with the North Penn Water Authority in Lansdale, Pennsylvania to study the effects that hydraulic behavior may have on contaminant propagation in the system. he study demonstrates that water quality varies not only with time but with space as well. ethods for continuous monitoring were evaluated as part of the study. everal different types of models were also developed in order to provide a framework for studying contaminant propagation.
