Weekly Flint Water Report: May 21-27

Here is this week’s Flint water report—late but not forgotten, due to some kind of weird screw-up at the Michigan DEQ site. First they didn’t have the data. Then eventually they did, but the spreadsheet was unreadable. Then they took everything down entirely. Then they finally reposted last week’s data. As usual, I’ve eliminated outlier readings above 2,000 parts per billion, since there are very few of them and they can affect the averages in misleading ways. During the week, DEQ took 392 samples. The average for the past week was 11.10.
