EPA: Drinking Water Contaminants
http://drinkingwater.utah.gov/documents/external/drinking_water_conta...
Fluoride. Many communities add fluoride to their drinking water to
promote dental
health. Each community makes its own decision about whether or not to
add fluoride.
EPA has set an enforceable drinking water standard for fluoride of 4
mg/L (some
people who drink water containing fluoride in excess of this level over
many years
could get bone disease, including pain and tenderness of the bones).
EPA has also
set a secondary fluoride standard of 2 mg/L to protect against dental
fluorosis.
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 not drink
water that
has more than 2 mg/L of fluoride.
Q: What happens when to much fluoride gets into the water?
A: When that happens the local-yocal water folks are required to notify
you.
The following is a form notice they use:
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
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
[name] has
a fluoride concentration of [insert value] mg/l.
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 4 mg/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.
For more information, please call [name of water system contact] of
[name of community
water system] at [phone number]. 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 [system].
For any exceedance of the fluoride secondary maximum contaminant level
SMCL, you
must provide public notice to persons served as soon as practical but
within 12
months after you learn of the exceedance (R309-220-11), using the
provided mandatory
language and filling in the blanks. The Division of Drinking Water may
have more
stringent deadlines or other requirements. Because fluoride at levels
above the
SMCL can permanently discolor children=s teeth, you are urged to issue
this
notice as soon as practical. Non-community systems that monitor for
fluoride (federal
law does not require non-community systems to monitor) are encouraged
to notify
their consumers if they exceed the SMCL, especially at water systems
serving children.
If you exceed the MCL of 4 mg/l, you must provide notice within 30 days
of learning
of the violation (R309-220-6(1)). See instructions for Fluoride MCL ?
Tier 2.
Community systems must use one of the following (R309-220-7(3)):
C Hand or direct delivery
C Mail, as a separate notice or included with the bill
In addition, you must use another method reasonably calculated to reach
others if
they would not be reached by the first method (R309-220-7(3)). Such
methods could
include newspapers, e-mail, or delivery to community organizations. If
you post
the notice, it must remain posted until the exceedance is resolved. If
the exceedance
has been resolved, you must post the notice for at least one week
(R309-220-7(2)).
If you mail, post, or hand deliver, print your notice on letterhead, if
available.
The notice on the reverse is appropriate for insertion in an annual
notice or the
CCR, as long as public notification timing and delivery requirements
are met (R309-220-7(4)),
as well as for a separate individual notice. The language on the
template is mandatory
and may not be modified, although you may add to the notice, as
suggested below
(R309-220-11).
Explaining the Situation
Use the following language, if applicable:
C Fluoride contamination is rarely due to human activity. Fluoride
occurs naturally
in some areas and is found in high concentrations in the aquifer in our
source water.
If the fluoride levels in the water have returned to below the SMCL, be
sure to
make this clear in your notice.
Corrective Actions
In your notice, you should describe corrective actions you took or are
taking, if
any. The bullet below describes one action commonly taken by water
systems with
fluoride SMCL exceedances. Use this language, or develop your own:
C We are continuing to monitor fluoride levels. We will inform you if
they exceed
the limit of 4 mg/l.
After Issuing the Notice
Make sure to send the Division of Drinking Water (PO Box 144830, SLC,
UT 84114-4830)
a copy of each type of notice and a certification that you have met all
the public
notice requirements within ten days after issuing the notice
(R309-105-16(3)).
