Due to yesterday's storm + several #CombinedSewerOverflows, red flags are flying in the Charles River. 🚩

Take caution when boating on the river today!

"Public health officials recommend avoiding contact with the river during rainstorms and for 48 hours afterward, as there may be increased health risks due to bacteria or other pollutants discharged by CSOs."

I get email alerts for Thames Water's #combinedseweroverflows, but I've just noticed that they're going to stop sending them at the end of the month now that the online status map (https://buff.ly/3ZAdXrv) is up and running. Guess that means I have to always have the map up?

Finally there is real time mapped information about #combinedseweroverflows in London easily available: https://buff.ly/3VOI3EC ! It's about time. Reminds me of when @fgregg & others created Is There Sewage In the Chicago River back in maybe 2012 https://buff.ly/3k54OqM ?
