CHICAGO (AP) — Rowers, kayakers and other users of the Chicago River are getting a real-time look at one measure of water quality in the system that weaves through downtown and some neighborhoods. Chicago nonprofit Current in 2019 installed three sensors in the river’s three main branches to continuously estimate the amount of bacteria that comes from human and other warm-blooded animals’ waste. The organization initially planned to begin making the real-time results public in 2020. But the coronavirus pandemic delayed their plans until Thursday, when a website updating with data taken every 15 minutes went online.
