Objective:
- Determine the molecular mechanisms responsible for virus inactivation
- Determine factors required for effective virus inactivation by natural sunlight and UVC
- Develop pond and UVC design guidelines to achieve reliable virus inactivation and elucidate trade-offs across and within dimensions of sustainability.
Progress Summary:
The uncertainties of five parameters (hour of the day, NPOC concentration, water depth, location, and quantum yield) accounted for most of the variance in total inactivation rate constant.
Future Activities:
Prepare peer-reviewed publication based on the evaluation of the relative importance of environmental, water quality, photoreactivity and engineering design factors on sunlight inactivation rates of viruses in surface waters
