JUST TWENTY-EIGHT DAYS BEFORE, I had known very little about water treatment, anticorrosives, service lines, and lead leaching. I hadn’t known much about lead exposure beyond paint and paint dust and bullets. I hadn’t met Marc or Senator Ananich or Andy. I couldn’t have told you the names of the directors in charge of the MDHHS or MDEQ. It was hard enough to keep track of the revolving door of EMs in Flint.
