When I saw this headline in the Scientific America magazine from August 20th, 2014, I was surprised for two reasons. The first is this magazine hasn’t been overly receptive of information of this nature over the last few years. The second reason is the controversy over fluoride in general.
Excess fluoride, which may damage both brain and bone, is leaching out of granite and into Maine’s drinking water—and potentially other New England states.
Like many states with granite rich soils Maine’s many small communities and residents, rely on private wells for the water they drink, bathe in and perhaps use to make infant milk formula. Newly available data, released in recent months, indicates that in some 10 communities in the state of Maine, wells harbor dangerously high levels of fluoride. In some cases, the wells contain more than double the level that the U.S. Environmental Protection Agency has deemed the acceptable maximum exposure level.
