Water undergoes substantial changes in quality between the time it leaves the treatment plant and the time it reaches the customer's tap, making it important to select monitoring stations that will adequately monitor these changes. But because there is no uniform schedule or framework for monitoring under the Safe Drinking Water Act, the degree of variability among monitoring requirements poses both management and technical barriers to states and water systems ultimately responsible for implementation of the regulations. Systematic and quantitative guidelines are provided here for locating monitoring stations. By using the concept of pathways, the authors applied the concept of coverage and inferred the quality at an upstream node from the quality at a downstream node. Includes 7 references, tables, figures.
