DRINKING WATER WARNING Raw Water Well sample tests positive for E. coli

Click title for link for an announcement that went out last Friday. It is supposed to be widely disseminated but I haven't heard anything about it. The press release seems to suggest that there is nothing to worry about, but then points out what symptoms you may have if you drink water with E.Coli in it. Not that reassuring a message.

Is this part of the reason for the increasing flushing of hydrants? Do we have a citywide water quality problem?
