This study was reviewed by the Institutional Review Board (IRB) at Stanford University and the IRB determined that this research does not involve human subjects as defined in 45 CFR 46.102(f) or 21 CFR 50.3(g). Daily sample collection at San José WWTPSan José (SJ) WWTP (San José-Santa Clara Regional Wastewater Facility) serves 75% (1,500,000 people) of Santa Clara County, California [29]. Daily samples of settled solids were collected between 15 November 2022 and 9 April 2023 (n = 146).

AbstractWe measured concentrations of SARS-CoV-2, influenza A and B virus, respiratory syncytial virus (RSV), mpox virus, human metapneumovirus, norovirus GII, and pepper mild mottle virus nucleic acids in wastewater solids at twelve wastewater treatment plants in Central California, USA. Measurements were made daily for up to two years, depending on the wastewater treatment plant.

AbstractIncreasing the efficiency of the processing units used to purify municipal wastewater to potable quality would enhance the sustainability of potable reuse. Conventional advanced oxidation processes using 254 nm UV light degrade contaminants by both direct photolysis and reaction with radicals produced by hydrogen peroxide photolysis. Treatment goals include 0.5-log removal of 1,4-dioxane, reducing N-nitrosodimethylamine to <10 ng l−1 and 6-log virus inactivation.
