Public Notice
Monroe Township Municipal Utilities
Authority
Monroe Township Municipal Utilities Authority announces that sampling of
the drinking water for Radionuclides at our well supplies during the
first and second quarter of 2007 indicated that 2 out of 7 of our wells
slightly exceeded the maximum contaminant levels for Radium.
The (MCL) maximum contaminant level for combined Radium
activity is set at an annual average of 5 pci/L. The level in our well
17/19 site is 5.62 pci/L.
The United States Environmental Protection Agency (EPA) sets
drinking water standards and has determined that Radium poses a health
concern at certain levels of exposure. The EPA has estimated that the
additional lifetime risk associated with drinking water that contains
the MCL level Radium is about 1 in 10,000. This means that if 10,000
people were to consume two liters of this water per day for 70 years, we
would expect to see one additional cancer in the 10,000 people exposed.
Increased risk of bone cancers and cancers of the head sinuses has been
associated with ingestion of Radium. Man has always been exposed to
natural radiation from water, food, and air, and the quantity of
radiation a person is exposed to varies with the background
radioactivity. Water of high radioactivity is unusual; nevertheless, it
is known to exist in certain areas from natural sources.
The EPA has set an enforceable drinking water standard for
Radium to reduce the risk of these adverse health effects. The MTMUA is
committed to addressing this problem and is in the process of applying
treatment to our wells which exceed the MCL. Meanwhile, we have placed
the above mentioned wells at the end of our operation sequence, so that
they do not come on unless absolutely necessary to meet water demands.
For more information, please contact us at 732-521-1700 or 609-655-1050
between the hours of 8:00 a.m. to 4:30 p.m.
RADIUM
NOTIFICATION CLARIFICATION
Dear Valued Customer,
Monroe Township Water is Safe
and Poses NO Health Risk!!!
In a mandatory letter you received earlier this month, that
message may not have been clear. We would like to take this
opportunity to address some concerns that have been expressed by
you following receipt of our letter.
Q:
What is radium and how does it get into a water supply?
A:
Radium is metallic element which
occurs naturally within the ground. As it decays, it produces
radon gas and alpha rays. If a well draws water from a layer
of sand which contains radium, it will produce water containing
alpha rays and sometimes radon gas.
Q: What
happened and what is the MTMUA doing?
A:
Two of our
wells, when pumping together, have slightly higher readings than
the Maximum Contaminant Level (MCL) for combined radium 226/228
of 5 pci/l (a running annual average of 5.6 pci/l for wells
17/19). The wells in question, Wells #17 and #19, are no
longer being used as a potable (drinking) water source. Well
#17 now feeds a separate and non-potable irrigation system, and
Well #19 is not being used at all. Since these wells are no
longer being utilized as a potable water source, there is no
longer a health concern and, therefore, consulting your doctor
is not necessary.
Q: What does all of this mean
to you? Is the water safe to drink?
A:
There is no guarantee that the bottled water you buy is any
lower in radium than tap water. In fact, tap water is subject
to more stringent requirements and standards than bottle
water. Even if the tested radium levels remained above the
MCL, it would take a lifetime (70 years) of consumption (2
liters per day) to raise any cancer risk by 1 in 10,000.
However, this is not an emergency condition and cause for
immediate concern. The required steps have been taken to
mitigate any risks associated with combined radium levels and
constant monitoring and testing for contaminants continues in
accordance with all safe drinking water regulations. The
Authority’s water currently meets all the NJDEP Safe Drinking
Water Standards, and is perfectly safe.
If you have any questions or
concerns please call the MTMUA offices at either 609-655-1050 or
732-521-1700.
