The quality of drinking water can change between the discharge from the treatment plant and the point of consumption. In order to study these changes in a systematic manner a Cooperative Agreement was initiated between EPA's Drinking Water Research Division and the North Penn Water Authority in Lansdale, Pennsylvania. Contaminant propagation models were developed and field tested. Two automatic water samplers for Volatile Organic Chemicals were evaluated. Major findings were that temporal and spatial variation of water quality in the North Penn Water Authority distribution system were found to be much greater than expected. Steady-state models can be used to predict water quality variations in a distribution system but dynamic models can provide much more insight into system behavior. System hydraulics plays a very important role in water quality variations.
