"The unregulated metal can harm bone development in children."
"About 2.3 million Americans are exposed to high natural strontium levels in their drinking water, a metal that can harm bone health in children, according to a United States Geological Survey study.
The study, published in Applied Geochemistry, found that almost every groundwater sample across 32 U.S. aquifers had detectable strontium levels, while 2.3 percent exceeded 4 milligrams per liter (mg/L), the maximum amount that people should consume routinely, according to the Environmental Protection Agency. The public and private wells extending from these aquifers provide drinking water for 2.3 million people.
While low amounts of natural strontium are safe and even beneficial for the human body, these high concentrations can stunt bone growth in children who lack adequate calcium intake. Strontium can replace calcium in bones, weakening them and limiting development, according to Sarah Yang, the Wisconsin Department of Health Services' groundwater toxicologist."
