Sulfate is a substance that occurs naturally in drinking water.
People unaccustomed to drinking water with elevated levels of sulfate can experience diarrhea and dehydration. Infants are often more sensitive to sulfate than adults. As a precaution, water with a sulfate level exceeding 400 mg/L should not be used in the preparation of infant formula. Older children and adults become accustomed to high sulfate levels after a few days.
If sulfate in water exceeds 250 mg/L, a bitter or medicinal taste may render the water unpleasant to drink. High sulfate levels may also corrode plumbing, particularly copper piping. In areas with high sulfate levels, plumbing materials more resistant to corrosion, such as plastic pipe, are commonly used.
SMCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Sulfate levels were detected in your water sample to exceed the secondary maximum contaminant level (SMCL).
ACTION IS OPTIONAL
Sulfate levels were detected in your water sample but do not exceed the secondary maximum contaminant level (SMCL).
