FWIW- if you just want a temp fix...I'd just pick up some distilled or r/o from the grocery store.

I'm not sure which areas are impacted for certain. It is not coming out of the treatment facilities with the pseudomonas but is picking it up in some of the transmission pipes or plumbing fixtures that have been colonized.
My husband's workplace had to add a new filtering system to their water intake and replace their massive water storage tank because of it. His workplace is in the Hillard area. They found it via their own testing.
At about the same time, Children's Hospital found it in their supply. You probably know where they are. They also had to take steps.
My brother's workplace in Cincinnati had the same thing show up a few years ago and had to make changes.
I suppose I shouldn't say my city is having issues with it, since you really wouldn't know without testing your own supply if your transmission pipes are affected.
I do know that once you get a Pseudomonas biofilm in your pipes you basically never get rid of it. It is a because the biofilm protects it from the chlorine.
Yet, it really isn't harmful for most people or pets. I don't hesitate to drink mine, even though I suspect it is contaminated.
Sorry if I scared you.
Maybe this will help:
"P. aeruginosa is part of a large group of free-living bacteria that are ubiquitous in the environment. This organism is often found in natural waters such as lakes and rivers in concentrations of 10/100 mL to >1,000/100 mL. However, it is not often found in drinking water. Usually it is found in 2% of samples, or less, and at concentrations up to 2,300 mL(-1) (Allen and Geldreich 1975) or more often at 3-4 CFU/mL. Its occurrence in drinking water is probably related more to its ability to colonize biofilms in plumbing fixtures (i.e., faucets, showerheads, etc.) than its presence in the distribution system or treated drinking water. P. aeruginosa can survive in deionized or distilled water (van der Jooij et al. 1982; Warburton et al. 1994)." - Rev Environ Contam Toxicol. 2009;201:71-115. doi: 10.1007/978-1-4419-0032-6_3.
Also from Rev Environ Contam Toxicol. 2009;201:71-115. doi: 10.1007/978-1-4419-0032-6_3. - "The risk of colonization from ingesting P. aeruginosa in drinking water is low. The risk is slightly higher if the subject is taking an antibiotic resisted by P. aeruginosa. The fact that individuals on ampicillin are more susceptible to Pseudomonas gastrointestinal infection probably results from suppression of normal intestinal flora, which would allow Pseudomonas to colonize."
If it is causing the spots in the orchids, it is also less likely to be the species that causes issues in humans, that is P. aeruginosa. I don't know if P. cattleya impacts people.

That makes sense.
I should have done more research before I brought this to boards.
Do Pseudomonas spp. impact orchids negatively?
