2009 – Conway, Arkansas

Fluoridation was stopped after a 42-inch water pipe corroded to the point of failure in October, necessitating the shutdown of a portion of Conway Corp.’s water treatment plant that was just built 3 years prior. The pipe corroded because the fluoride injection port was mounted too close to a chlorine injection port, resulting in a highly acidic concentration of the two chemicals. Conway Corp.’s customers were never informed by the city-owned utility service of the change to their drinking water. Arnold apologized on behalf of the corporation in a letter to be distributed to customers this week.

2008 – Germania Springs, Alabama
