I am skeptical of reports published by the cities. There is incentive for the reports to skew positive, since otherwise individuals can lose elections/jobs/contracts. So I looked back at the 2014-2016 reports from Flint, Michigan to see if they correctly predicted the water crisis. They did, but only very subtly. In 2014, there was a single violation of too many total trihalomethanes: https://www.cityofflint.com/wp-content/uploads/2014/01/CCR-2014.pdf https://www.cityofflint.com/wp-content/uploads/2014/01/CCR-2... In 2016, there were no declared violations, even though the 90th percentile sample of lead concentration (20 ppb) was over the 15 ppb limit: https://www.cityofflint.com/wp-content/uploads/City-of-Flint-2016-Annual-Water-Quality-Report.pdf https://www.cityofflint.com/wp-content/uploads/City-of-Flint... Also note that while in the US the lead concentration limit is 15 ppb, Canada has recently reduced its limit from 10 ppb to 5 ppb. Nearly every US city I've looked at exceeds 5 ppb.
