Inorganics

Sulfate

Anion composed of sulfur and oxygen, is almost universally present in water

Health Guideline Level (HGL)

500 ppb

Maximum level that poses minimal health risk based on the latest science

Health Effects

Elevated sulfate concentrations may have a short-term laxative effect and cause dehydration, especially among infants. There are no known chronic health risks associated with sulfate.

Affected Organs & Systems:

Gastrointestinal

Common Sources

  • Dissolves into groundwater as it passes through mineral deposits, soil, and rock formations that contain sulfate minerals
  • Waste streams from industrial activity or agricultural runoff can also contribute to sulfate in groundwater or surface water supplies
  • Aluminum sulfate is often used in conventional water treatment, which can contribute sulfate to drinking water

How to Remove It

Water filters certified under the following NSF standards are effective at removing Sulfate:

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

Sulfate is classified as a Inorganics contaminant.

This contaminant primarily affects the gastrointestinal.
