Sulfate
General Information
Sulfate occurs naturally in drinking waters. Sulfate is usually present from naturally occurring magnesium or sodium sulfate. Levels greater than 250mg/L may cause a laxative effect. The laxative effect is intensified when a sudden change occurs from drinking water with low sulfate concentrations to drinking water with high sulfate concentrations.
Corrective Action
You can switch to bottled water if desired or treat the water with reverse-osmosis filtration.
