Our new paper on @WaterRes_J talks about phosphate and anode materials interfere with Cu antimicrobial effects towards L. pneumophila (this strain has high copper tolerance as well). @waterARGome @WjRhoads strain https://www.sciencedirect.com/science/article/pii/S0043135423006140

Also, some speculation about future use pipe surface temperature probes as a useful (non-invasive) diagnostic and monitoring approach. Check it out and let us know what you think! (5/5)

Boiler turnover resulted in Legionella being resuspended from the bottom of the boiler and/or (when RAPIDLY flushed) sloughing off biofilm in the pipes. (4/4)

When extensive preventative flushing occurred – similar to many recommendations prevalent at the time – Legionella levels actually INCREASED for a few weeks. (3/5)

Legionella numbers go up, down, and don’t change during 3-7 week periods of low water demand. Water demand alone doesn’t explain it; have to consider temperature set point, hot water recirculation (and convective mixing), nutrient flux, … etc. (2/5)

New case study with @celine_marg and @DrinkMic in @Micro_MDPI all about Legionella during periods of low water demand associated with COVID stay-at-home and winter holidays…and flushing as a “preventative” measure https://t.co/ebaaHgBndX (1/5)

When stay-at-home orders were issued to slow the spread of COVID-19, building occupancy (and water demand) was drastically decreased in many buildings. There was concern that widespread low water...

Just found this paper - super cool work from the VT crew.
Wading into chlorine disinfection and Legionella risks with a two-year chlorine surveillance study in Flint, MI published in @WaterRes_J. Seven citizen scientists/co-authors led by Ms. Kaylie Mosteller. Work conceived/co-led w/ Dr. Marc Edwards. https://t.co/p3sQI9Wqb9

sometime the journal default is pdf. but at least they put the data...as someone who is now mining data from old pubs, most of what's out there is unusable for meta analyses without even worse headache than converting pdf to excel...
people who put massive data tables into pdf supplementary .... why

Check out our Curr Opin piece- We've built sewage infrastructure to monitor SARS-CoV-2, let's use it to direct our efforts against other public health threats, e.g., antimicrobial resistance @petervikesland @rodahusa @HEARD_PIRE

Looking at your local COVID data? Check out this insanely amazing thread by @zorinaq. Data visualization is awesome, but be very careful where you get supplemental info to help digest and interpret graphs. Simply looking at the charts is really not enough.
COVID deaths & hospitalizations always lag cases. The lag has been demonstrated, is often 𝗺𝗼𝗿𝗲 than a month, and its timing can be predicted accurately (I have done it.) The #casedemic folks are just, well, wrong. A thread explaining the lag with real-world examples. 1/n

Data collection during legionellosis outbreak investigations and major changes in water treatment plant processes (even upgrades!) needs to improve so we can adequately understand risk to public health. https://t.co/AfdY4RKe1j

Fifty-eight people were sickened and 12 died from a Legionnaires’ disease (LD) outbreak in Quincy, IL, in 2015. The initial outbreak investigation identified deficiencies at the Illinois Veteran’s...
