Thank you for telling everyone that you are not even remotely involved in water treatment, especially for those that are. No matter the treatment method, absolutely purified water can encounter pathogens. The water treatment process uses various methods to make water safe for consumption but the distribution system requires a residual for any biological contaminants that can enter, or be harbored within, and low concentrations of free chlorine (<2 ppm) provide that while carrying very little risk. Especially compared to most risks in modern life, like being in a passenger vehicle. Safe drinking water, partially due to chlorination is the greatest public health achievement of humanity so far. You are spreading misinformation.
It was low-quality humor. I figured the midi-chlorian reference gave it away, due to the high density of Star Wars fandom on this site. Sorry to trigger you. I added a joke indicator, and I hope your blood pressure will decrease.
It was obvious. Don't waste everyone's time talking way outside your level of expertise and then trying to make jokes when you're called out. It's juvenile.
It was CookieEngineer who made the original comment about something to do with biological cleaning of water.
You may have caught that, but it was Tomcan who made the "joke" comment. I just read it as they responded to your question, but added the terrible humour to imply that they didn't take it seriously.
