Determiniation of Flouride Ion in Well Waters of Eastwood School District, Wood, County, Ohio

Abstract

The purpose of this investigation was to determine the amount of fluoride ion present in the well water of Eastwood Local School District, Wood County, Ohio. Ninety-two water samples were gathered from separate wells in the district and analyzed for fluoride content. Fluoride determination was made with a fluoride ion-selective electrode using a direct potentiometric method. pH measurements were also made upon the samples. Fluoride levels were found to range from 0.6 to 3.8 parts per million. pH measurements varied from 6.91 to 8.30.
