Sulfate
Anion composed of sulfur and oxygen, is almost universally present in water
EPA MCLG Level
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:
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:
