City of Keokuk Awarded Grant to Upgrade Water Fluoridation System and Protect Residents’ Healthy Teeth

Posted on July 19, 2022 in Foundation

The City of Keokuk, Iowa, will upgrade its community water fluoridation equipment thanks in part to a $25,000 grant from the Delta Dental of Iowa Foundation. Community water fluoridation (fluoridation) is the adjustment, up or down, of natural fluoride levels in water systems to prevent tooth decay (cavities). According to the Iowa Department of Public Health, water fluoridation prevents 25 percent of tooth decay for all age groups and for every $1 spent on community water fluoridation, $38 is saved in dental treatment costs.

“Research shows that assisting communities like Keokuk with fluoridation is an important and effective strategy for overall public health,” said Dr. Jeffrey Chaffin, chief dental officer, Delta Dental of Iowa and board director, Delta Dental of Iowa Foundation. “Fluoridation programs were identified as one of the top 10 public health achievements of the 20th century, and communities like Keokuk continue to improve the oral and overall health of residents by making investments like this.” 

These system upgrades will enable Keokuk Municipal Waterworks to convert from a solid fluoride feed to a liquid fluoride feed, improving process control and maintaining this equitable and effective method for cavity prevention. Keokuk’s water system serves a population of 9,900 in Lee County. It is estimated that there are 2,130 people per dentist in the county. 

“The health and safety of Keokuk residents and our employees are of utmost importance to our community and this grant helps us make these necessary system upgrades,” said Mayor K.A. Mahoney, City of Keokuk. “I fully support our Waterworks team to maintain and improve the delivery of quality water to our residents and fluoride delivery is a big part of that.” 

Working with the Iowa Department of Public Health, Delta Dental of Iowa Foundation provides funding to maintain and support optimally fluoridated water in public water systems. This program can help Iowans of all ages receive a health benefit that helps prevent cavities.
