Boron
Boron is an element that occurs naturally in the earth's crust as borate minerals. It can be found in food, consumer products and some water sources, including some bottled water and groundwater from highly mineralized aquifers. While evidence suggests it is likely an essential nutrient for human health, animal studies have shown that exposure to high levels of boron can cause adverse developmental and reproductive effects.
Health Guideline Level (HGL)
0.5 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective levels of boron in drinking water have been established based on potential developmental toxicity.
Affected Organs & Systems:
Common Sources
- The most significant sources of boron in drinking water are the natural erosion rocks and soils, manufacturing plants that use boron (like glass manufacturing and coal-burning power plants), wastewater, and agricultural activity (fertilizers/pesticides).
How to Remove It
Water filters certified under the following NSF standards are effective at removing Boron:
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
Boron is classified as a Inorganics contaminant.
This contaminant primarily affects the developmental.
