A thread. When I was a young assistant professor at my first university (late 70's), my then Dean told me that in a few years there would be no need for #environmentalengineering. (he was in materials). Since then, we've had:
1/N
need to control protozoa in drinking water
hazardous waste remediation
wastewater reuse
the energy/water nexus
PFAS
indoor air quality/respiratory infectious diseases
materials recovery from wastewater
etc.
I left that first university after 3 years.
2/N
some take-home lessons:
- if you are sure of what you do, stay with it, and ignore the naysayers
- if you need to leave your first position, do so
- strive for excellence
- some academic administrators can be very ill-informed
the irony of the situation:
3/N
A few years after I left that first university, that Dean left to become a university president elsewhere. One of the early things he did at his new university was to start an environmental engineering program!
4/N
And he was also elected to @theNAEng

So not all ill-informed people are irretrievable.
end/N
@theNAEng Minor correction - he actually was not a member of @theNAEng , but received many other honors. (And was actually apparently a great college president)

N+1/N

Partial good news out of @CDCgov today. cdc.gov/coronavirus/20…
Recognition that fomites are a minor route, and stop the #hygienetheatre . Also good, and pathbreaking that they cite #QMRA studies in support. 1/N
Interesting that they use a 1/10,000 from a surface contact as being indicative of low risk from fomites (many of us have seen that number before). But, still some problems in this updated science brief. 2/N
Opening sentence: "The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory droplets carrying infectious virus." While they don't use the word #aerosol in the body 3/N

The fallacy of #fomites.
There has been a lot of attention devoted to the potential transmission of #COVID19 by fomites, a lot of money and time spent on "sanitizing" surfaces, and on marketing various chemicals, treatments, etc. 1/N
While generically, cleanliness is good, I am convinced that the vast amount of these efforts when targeted at #COVID19 are misguided and represent more #hygienetheatre than true prevention. 2/N
First, I have yet to see any reports of transmission that convincingly demonstrate a fomite route (as opposed to a couple of cases reports that allege this as a diagnosis of exclusison, while failing to consider more plausible routes such as aerosols). 3/N

I wish in this rush to reopen, there was not the unstated assumption that everyone can just hop into their private car (bubble) and get from the personal home to their personal office. We don't have teleportation. 1/N
Some must rely on public transit and may not have other options, and the comfort level with this needs to be substantially assured. In office buildings, there is growing recognition of "choke points" such as 2/N
elevators, lobbies, etc., which could make gathering points for people. In schools and universities, corridors, stairways, etc. have not been designed for efficient movement in a physically distanced way. This 3/N
