Strontium
Metallic element with both stable and radioactive isotopes
Health Guideline Level (HGL)
3 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Due to its similarity to calcium, stable strontium is readily taken up into bone. Health protective levels for stable strontium in drinking water are designed to protect children, a vulnerable population to stable strontium exposure. Elevated levels of stable strontium are associated with bone development issues in children, particularly strontium rickets (associated with abnormally thick and short bones). Animal studies corroborate a link between strontium ingestion and bone and cartilage development issues.
Affected Organs & Systems:
Common Sources
- Occurs naturally throughout the earth's crust
- Present in nearly all surface and groundwater through the weathering of rocks and soils
- High levels of stable strontium can be released into water drawn from bedrock aquifers rich in strontium minerals
- Can also enter water as a result of coal and oil burning, mining, and industrial release
How to Remove It
Water filters certified under the following NSF standards are effective at removing Strontium:
Health Guideline Level
The HGL represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Strontium is classified as a Metals contaminant.
This contaminant primarily affects the developmental, skeletal.
