On our way to the hearing, Marc was stopped by a woman who recognized him. She had graying hair and looked worn and tired. She said she was an activist in D.C. and had a son who was a baby during the lead exposure. A teenager now, the boy’s learning and behavioral problems were significant. “There is not a day that goes by that I don’t wonder if it was the D.C. water that impacted my son,” she said, then thanked Marc for his work.
