ATHOL, Idaho (AP) -- Tests of a small northern Idaho community water system showed arsenic at levels about nine times what the federal government allows, prompting residents to drink bottled water.
The Coeur d'Alene Press reports a test two months ago showed naturally occurring arsenic in the Lynnwood Estates Water Association well near Athol reached 91 parts per billion. The federal limit is 10 ppb.
Arsenic is a potent poison.
The well serves 18 homes.
Since then, the arsenic level has plummeted, but it's still above the federal limit. Some Department of Environmental Quality officials speculate the spike was a seasonal occurrence.
One resident, Bill Campbell, says he's drinking bottled water -- and considering a lawsuit.
Association officials considered installing water filters inside homes, but they are expensive, at $180 every six months.
