Why check for Sulfate?

Sulfate is a substance that occurs naturally in drinking water. Ingestion of high levels of sulfate in water can have a laxative effect; this is a health concern because serious cases can lead to dehydration. Because of aesthetic effects (i.e. taste and odor) Sulfate is classified as an EPA secondary contaminant. The Secondary Maximum Contaminant Level (SMCL) for Sulfate is 250 mg/L (ppm). Sulfate minerals, such as Calcium Sulfate, produce scale buildup in water pipes.  Water that contains high sulfate levels will taste “bitter” and may be corrosive for plumbing, particularly copper piping.
