Hello, fellow US-based people. If you, like me, are alarmed at COVID tracking infrastructure being pulled offline, consider: https://data.wastewaterscan.org/

@josh Here is the site for Colorado’s statewide sewage monitoring. Hopefully it will continue, and hopefully other states have similar data.
@2ck Yes! Oops.
