Contaminants of Emerging Concern: Considerations for Planned Indirect Potable Reuse

摘要

Planned indirect potable reuse (IPR) is defined as the planned incorporation of reclaimed water into a raw water supply, such as in potable water storage reservoirs or a groundwater aquifer, resulting in mixing, dilution, and assimilation, thus providing an environmental buffer (M&E, 2007) before it is treated and supplied through potable water distribution systems. Planned IPR projects have been in operation in the US since the 1960s and the number of projects across the US has grown in the past few decades.
