I'm not highly worried over impounded water contamination from Hg in fluorescents. I am, however, quite concerned that there is now, and will be for a long time, exposure to young humans from household compact fluorescents, and that embriologic and epidemiologic examinations (based on neurological toxic issues among other things) won't have sufficient data to reveal toxicity for a decade or so.
It's more of an inhalation issue than a drinking water issue.
