We're pleased to present to you this
year's Annual Quality Water Report. This report is designed to inform you
about the quality water and services we deliver to you every day. Our
constant goal is to provide you with a safe and dependable supply of
drinking water. We want you to understand the efforts we make to continually
improve the water treatment process and protect our water resources. We are
committed to ensuring the quality of your water. Our water source is
groundwater. We have five wells that draw from the Manokin
and Ocean City Aquifers.
The Division of Public Health in
conjunction with the
Department of Natural Resources and Environmental Control has
conducted a source water assessment. If you are interested in reviewing the
assessment, please contact Town Hall @
302-539-8011 regarding how to obtain a
copy. Or go on-line @
htpp:\\www.wr.udel.edu\swaphome\swassessments.htm.
It
provides information such as potential sources of contamination.
I'm pleased to report that our drinking
water meets federal and state requirements.
If you have any questions about this
report or concerning your water utility, please contact Cliff Graviet @
302-539-8011. We
want our valued customers to be informed about their water utility. If you
want to learn more, please attend any of our regularly scheduled meetings.
They are held on the third Friday of each month @ 7:30 p.m. at the Town
Hall, 214 Garfield Parkway.
Public Health, Office of Drinking Water
and the Bethany
Beach Water Department
routinely monitor for constituents in your drinking water
according to Federal and State laws. This table shows the results of our
monitoring for the period of January 1st to December 31st,
2007. As water travels over the land or underground, it can pick up
substances or contaminants such as microbes, inorganic and organic
chemicals, and radioactive substances. All drinking water, including
bottled drinking water, may be reasonably expected to contain at least small
amounts of some constituents. It's important to remember that the presence
of these constituents does not necessarily pose a health risk.
In this table you will find many terms
and abbreviations you might not be familiar with. To help you better
understand these terms we've provided the following definitions:
Non-Detects (ND) - laboratory analysis
indicates that the constituent is not present.
Parts per million (ppm) or Milligrams per liter (mg/l)
- one part per million corresponds to one minute in two years or a single
penny in $10,000. Or 1 drop in 13 gallons.
Parts per billion (ppb) or Micrograms per liter
- one part per billion corresponds to one minute in 2,000 years, or a single
penny in $10,000,000. Or 1 drop in 13,000 gallons.
Action Level - the concentration of a
contaminant which if exceeded, triggers treatment or other requirements
which a water system must follow.
Treatment Technique (TT) - A treatment
technique is a required process intended to reduce the level of a
contaminant in drinking water.
Maximum Contaminant Level (MCL) - The
“Maximum Allowed” (MCL) is the highest level of a contaminant that is
allowed in drinking water. MCLs are set as close to the MCLGs as feasible
using the best available treatment technology.
Maximum Contaminant Level Goal (MCLG) - The
“Goal”(MCLG) is the level of a contaminant in drinking water below which
there is no known or expected risk to health. MCLGs allow for a margin of
safety.
Maximum Residual Disinfectant
Level (MRDL)
– The highest level of a disinfectant allowed in drinking water. There is
convincing evidence that addition of a disinfectant is necessary for control
of microbial contaminants.
Maximum Residual Disinfectant
Level Goal (MRDLG)
– The level of a drinking water disinfectant below which there is no known
or expected risk to health. MRDLGs do not reflect the benefits of the use
of disinfectants to control microbial contaminants.

All other contaminants were ND in
compliance with the Safe Drinking Water Act.
As you can see by the table, our system
had no violations. We’re proud that your drinking water meets or exceeds all
Federal and State requirements. We have learned through our monitoring and
testing that some constituents have been detected.
The EPA has determined that level in your water is below the MCL.
The sources of drinking water (both tap
water and bottled water) include rivers, lakes, streams, ponds, reservoirs,
springs, and wells. As water travels over the surface of the land or through
the ground, it dissolves naturally occurring minerals and, in some cases,
radioactive material, and can pick up substances resulting from the presence
of animals or from human activity. In order to insure tap water is safe to
drink, EPA prescribes regulations which limit the amount of certain
contaminants in water provided by public water systems. Food and Drug
Administration regulations established limits for contaminants in bottled
water, which must provide the same protection for public health.
All drinking water, including bottled
water, may reasonably be expected to contain at least small amounts of some
contaminants. The presence of contaminants does not necessarily indicate
that the water poses a health risk. More information about contaminants and
potential health effects can be obtained by calling the Environmental
Protection Agency's Safe Drinking Water Hotline at 1-800-426-4791.
MCL’s are set at very stringent levels.
To understand the possible health effects described for many regulated
constituents, a person would have to drink 2 liters of water every day at
the MCL level for a lifetime to have a one-in-a-million chance of having the
described health effect.
In our continuing efforts to maintain a
safe and dependable water supply it may be necessary to make improvements in
your water system. The costs of these improvements may be reflected in the
rate structure. Rate adjustments may be necessary in order to address these
improvements.
Some people may be more vulnerable to
contaminants in drinking water than the general population. Immuno-compromised
persons such as persons with cancer undergoing chemotherapy, persons who
have undergone organ transplants, people with HIV/AIDS or other immune
system disorders, some elderly, and infants can be particularly at risk from
infections. These people should seek advice about drinking water from their
health care providers. EPA/CDC guidelines on appropriate means to lessen the
risk of infection by cryptosporidium and other microbiological contaminants
are available from the Safe Drinking Water Hotline (800-426-4791).
Please call our office if you have
questions.
We at Bethany Beach Water Department
work around the clock to provide top quality water to every tap, said
Ron Foreman.
We ask that all our customers help us protect our water
sources, which are the heart of our community, our way of life and our
children’s future.
