Abstract<\/div>\n

\\n<\/p>\n

The Dutch Drinking Water Act of 2011 requires water suppliers to run a Quantitative Microbial Risk Assessment (QMRA) every four years. This helps them check how safe their drinking water is from pathogens like enterovirus, Campylobacter, Cryptosporidium, and Giardia. The goal is simple: less than one infection per 10,000 people each year. But at Evides Water Company, they had a question: is their current water treatment, which mainly uses UV and chlorine dioxide, really enough to cut down adenovirus (AdV) levels? This study set out to answer that.<\/p>\n

\\n<\/p>\n

We estimated AdV concentrations in the source water in a few ways. We counted total AdV using integrated cell culture PCR (iccPCR), most probable number PCR (mpnPCR), and quantitative PCR (qPCR). We also counted AdV40\/41 with mpnPCR and qPCR. Why AdV40\/41? It makes up a big chunk of total AdV, and only a tiny fraction of AdV is actually infectious-about 1 in 1700. We looked at past studies and real-world plant data. Somatic coliphages turned out to be a good, reliable indicator for how well UV light disinfects AdV. Likewise, bacteriophage MS2 was a strong indicator for chlorine dioxide disinfection.<\/p>\n

\\n<\/p>\n

We then used literature data to fit the extended HOM model, seeing how effective chlorine dioxide disinfection was. What did we find? Chlorine dioxide treatment, even at low initial concentrations (0.05-0.1 mg\/l), was the key player. It did enough on its own to meet the health-based safety goal. UV disinfection for AdV, whether at 40 mJ\/cm(2) or 73 mJ\/cm(2), just wasn’t enough without that chlorine dioxide step. (C) 2019 Published by Elsevier Ltd.<\/p>\n
