Table 2 Hypothetical IPR (meeting one third supply) for six selected cities and its impacts on proportion of reclaimed water in supply (%) (after dilution with natural flow at the augmented source) and PPCS metrics.
From: Comparison of potential drinking water source contamination across one hundred U.S. cities
