    Health department investigators and town water department officials inspected the fluoridation system at the town's main water treatment plant.


    Thirty-four of 62 restaurant patrons reported acute gastrointestinal illness over a 24-hour period.

    Twenty of 61 households that used the community water supply reported one or more residents with acute gastrointestinal illness over a four-day period, compared with 3 of 13 households that did not use the community water supply.

    Restaurant water and ice samples contained more than 40 milligrams of fluoride per liter (mg/L), more than 20 times the recommended limit, and a tap water sample from a house located near the main treatment plant contained 200 mg/L of fluoride. (...)
