This one falls in the category of “yet another problematic thing to think about”. In this article “Considerations for Large Building Water Quality after Extended Stagnation” the authors are not talking about COVID19 per se. They are discussing the hazards associated with stagnant water after building remain closed for a long time because of the …
Another NASEM meeting of possible interest. Both in person and online, October 22nd, 2018. Here’s a link to the registration. We invite you to join the open session of our fourth committee meeting.

I just got pointed to this article today “Ugly Ducklings – the dark side of plastic materials in contact with potable water“, along with the accompanying commentary “About duck, pipes, and microbiomes“. I think this is a fascinating study for a few reasons. Firstly, like probably most parents, I observed and wondered about the biofilms …
Amy Pruden gives a talk about “Towards Prebiotic/Probiotic Control of the Microbiome in Built Water Systems.” This was recorded at the MoBE 2017 symposium in Washington D.C. If you’re interested, check out all of the other speakers from MoBE 2017 on our YouTube channel!
There is a new open access paper of possible interest to those working on water systems, green buildings, and/or microbial ecology: Survey of green building water systems reveals elevated water age and water quality concerns – Environmental Science: Water Research & Technology (RSC Publishing) DOI:10.1039/C5EW00221D By William J. Rhoads, Amy Pruden and Marc A. Edwards in Environmental …
Quick post here on a hospital water sampling study in Italy that found much higher levels of potentially pathogenic bacteria (e.g. Legionella) in aerators than in the rest of the plumbing system. Reading this gives a really good sense of how complicated it is to maintain a sufficiently sterile water distribution system for immunocompromised patients …
[edited from the ASHRAE press release] Changes to clarify requirements in a proposed standard are open for public comment. The proposed ASHRAE standard, 188P, Prevention of Legionellosis Associated with Building Water Systems, specifies what must be done to control the spread of legionellosis. The standard helps facility managers/owners understand how to apply the available information …
