The EPA regulated the allowable level of THMs in drinking water at 100 parts per billion. THMs are not found in the Bluffton wells. Fluoride is added to drinking water to help prevent tooth decay. We do not add fluoride to the Bluffton wells. Nitrates are substances that are formed when nitrogen-oxygen chemical units combine with various organic and inorganic compounds.

Inorganic nitrates, such as potassium nitrate and ammonium nitrate, are widely used in fertilizers. Fluoride is added to drinking water to help prevent tooth decay. We do not add fluoride to the Bluffton wells. Any detected level is from naturally occurring fluoride deposits found in the Floridan Aquifer. Turbidity is a measurement of the clarity of the water.
