An expert panel has recommended in vitro assays to screen for emerging contaminants in recycled water for potable reuse applications in California (USA). These bioanalytical tools would help identify chemicals of interest using a risk-based framework. The first phase of monitoring will focus on estrogen and aryl hydrocarbon receptor-based endpoints.

This project is addressing an important limitation in the ability to monitor the performance of advanced oxidation processes used to treat recycled water for drinking. The work is focused in the development of a validation framework incorporating critical control point monitoring with validated quantitative relationships between oxidation performance and operational parameters.

Ozone is a potent disinfectant that is frequently used in water treatment and reuse, yet its efficacy for pathogen control is difficult to monitor in real-time. As such, the disinfection potential of ozone cannot be fully exploited. Here we present an evaluation of two easy-to-monitor proxies that allow to monitor the inactivation of human viruses during ozonation of water and wastewater.
