Strontium in Nebraska: what the data shows
Nebraska has 18 cities with strontium data from the EPA's UCMR 3 program (2013–2015). Strontium was detected above the 1,500 µg/L EPA health reference level in 1 of those cities. The state average max detected level is 771.8 µg/L. Strontium occurs naturally in groundwater, particularly in areas with limestone and dolomite geology. It can also enter water from industrial waste and mining operations. There is no federal MCL for strontium, but the EPA established a health reference level (HRL) of 1,500 µg/L. Long-term exposure to strontium above the HRL may affect bone health, particularly in children, by substituting for calcium in developing bones. Reverse osmosis and ion exchange systems are effective at removing strontium from drinking water.

Frequently asked questions about strontium in Nebraska
Is strontium in Nebraska tap water harmful?
Strontium at low levels is not considered harmful, but the EPA set a health reference level (HRL) of 1,500 µg/L based on potential bone effects. 1 cities in Nebraska exceed this HRL. There is currently no federal MCL for strontium. Children may be more susceptible because strontium can substitute for calcium in developing bones.
How can I remove strontium from my drinking water?
Reverse osmosis and ion exchange (water softener) systems are effective at removing strontium from drinking water. Standard carbon filters are NOT effective. If your water comes from a well in an area with limestone or dolomite geology, consider testing for strontium.
