The primary goal of this project was to develop a sampling model which can be used to specify the sampling frequency needed to determine compliance with the microbiological maximum contaminant levels of the National Interim Primary Drinking Water Regulations. Two approaches to model development were used. The emperical approach was based on fitting coliform data to frequency distributions. The mechanistic approach was an attempt to analyze the physical elements of the water system in order to determine if samples from a particular location are representative of water quality over an area and if it is more likely that coliforms will be found in certain types of sampling locations.
