Thank you for that info. I also found this report, which may be of interest, from the University of Arizona in 2008 for Coronavirus survival in water and waste

Thank you for that info. I also found this report, which may be of interest, from the University of Arizona in 2008 for Coronavirus survival in water and wastewater: https://west.arizona.edu/sites/default/files/data/Gundy2008_Article_SurvivalOfCoronavirusesInWater.pdf https://west.arizona.edu/sites/default/files/data/Gundy2008_... 10 days or more in water, and 2 to 4 days in wastewater. My local municipality only uses chlorine, so I am a bit concerned. We had our own sand filtration system, but ‘decided’ to instead use the town next-door’s system, instead.
