The Examiner is reporting that parents who’ve brought a suit against D.C. Water for lead contamination have requested that the case be turned into a class-action suit for anyone under the age of 6 who drank tap water between 2000 and 2004.

For what it’s worth: Last summer, D.C. tap water made it into a list of the 25 best tasting area water systems in the country.
