Fluoride Notice included in 2018 Water Quality Report
At Easton Utilities, we are committed to providing clean, reliable water to our customers. The following information details the fluoride concentration and its potential health effects in the drinking water supplied by Easton Utilities.
Supplemental Information for our Customers Regarding Fluoride in Easton’s Drinking Water
The Town of Easton is supplied with drinking water by five groundwater wells. Two of the five wells are approximately 1,200 feet deep and three of the wells are 1,000 feet deep. Compared to many other wells used for water supplies, these wells have a very high degree of protection from man-made contamination. As a result, the chemical constituents in the water provided by these wells are naturally occurring.
Fluoride is a naturally occurring substance in groundwater. Between January 1 and March 26, 2017, one of Easton’s wells produced water with fluoride levels between 2 and 4 milligrams per liter (mg/l). The maximum fluoride level measured at this well (#10) in 2017 was 2.65 mg/L. Well #10 was permanently removed from service on March 26, 2017. In 2017, before Well #10 was removed from service, the water produced from that source was minimal and accounted for less than 0.1 percent of the total water produced by all wells during the first three months of 2017.
In March 2017, Easton Utilities conducted sampling and testing of the drinking water for fluoride concentration at 15 locations throughout the town. The sample locations were selected to provide a representative cross section of our water distribution network. The level of fluoride in these samples ranged from less than 0.5 mg/L to 0.951 mg/L.
Because it is possible that some customers could on a rare occasion have received water that contained a fluoride concentration of greater than 2 mg/l, we are required by the US Environmental Protection Agency (US EPA) and Maryland Department of the Environment (MDE) to provide all of the customers with the official public notice below.
Drinking Water Warning
Elevated Fluoride Levels Detected
This is an alert about your drinking water and a cosmetic dental problem that might affect children under nine years of age. At low levels, fluoride can help prevent cavities, but children drinking water containing more than 2 milligrams per liter (mg/l) of fluoride may develop cosmetic discoloration of their permanent teeth (dental fluorosis). The drinking water provided by your community water system (Easton) has had Fluoride concentrations of between 0.748 mg/l to 2.65 mg/l, with the highest levels anticipated when Easton’s former stand-by well (#10), located west of Easton Parkway on Glenwood Ave. was operated.
Dental fluorosis, in its moderate or severe forms, may result in a brown staining and or pitting of the permanent teeth. This problem occurs only in developing teeth, before they erupt from the gums. Children under nine should be provided with alternative sources of drinking water or water that has been treated to remove the fluoride to avoid the possibility of staining and pitting of their permanent teeth. You may also want to contact your dentist about proper use by young children of fluoride-containing products. Older children and adults may safely drink the water.
Drinking water containing more than 4 mg/l of fluoride (the U.S. Environmental Protection Agency’s drinking water standard) can increase your risk of developing bone disease. Your drinking water does not contain more than 4mg/l of fluoride, but we’re required to notify you when we discover that the fluoride levels in your drinking water exceed 2 mg/l because of this cosmetic dental problem.
Some home water treatment units are also available to remove fluoride from drinking water. To learn more about available home water treatment units, you may call NSF International at 1-877-8-NSF-HELP.
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses.) You can do this by posting this notice in a public place or distributing copies by hand or mail. This notice is being sent to you by Easton Utilities, State Water System ID #: MD0200003. Date distributed: 6/1/2018.
