WATER QUALITY REPORT
City of Bedford Municipal
Water System
Meets all drinking water standards
Is continuously tested
Is safe to drink
The City of Bedford
Water Treatment System is pleased to present to you this Annual
Drinking Water Quality Report for 1999. 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 safety and quality of your water.
TYPE
AND SOURCE OF OUR WATER SUPPLY
Our main water source
is the Stoney Creek Reservoir located on Rt. 640 in Bedford County,
which is a surface water source. We have a supplemental source
that is used presently during periods of dry weather and could
be utilized in the future as demand increases. This surface water
source is located at the head of Big Otter River, off Route 43
North, in the Kelso area of Bedford County. As the present time
we monitor the drainage areas of our source water for types of
operations that may contribute contaminants. This source water
protection will receive more attention in the future as a result
of the Safe Drinking Water Act. The Virginia Department of Health
will be completing an assessment of the drainage area for our
source water and any future development of the drainage areas
of our source water will be monitored.
STRIVING
FOR EXCELLENCE
We
are pleased to report that our drinking water is safe and meets
federal and state requirements. This report shows our water quality
and what it means. If you have any questions about this report
or concerning your water utility, please contact your Water Treatment
Facility Superintendent at 586-7197 during the hours of 8:00 a.m.
to 4:00 p.m., Monday through Friday. 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 council meetings.
They are held on the second and fourth Tuesday at 7:30 p.m. each
month in the City of Bedford Council chambers located in the City
of Bedford Municipal Building.
SUBSTANCES
EXPECTED TO BE IN OUR DRINKING WATER SUPPLY
The
City of Bedford Water Treatment System routinely monitors for
constituents in your drinking water according to Federal and State
laws. The following table shows the results of our monitoring
for detected contaminants for the period of January 1st to December
31st, 1999. We are allowed to monitor for certain regulated contaminants
less often than once a year. Where this is applicable in the table,
it will be noted. All drinking water, including bottled drinking
water, may be reasonably expected to contain at least small amounts
of some constituents. Its important to remember that the
presence of these constituents does not necessarily pose a health
risk.
In the following table
you will find many terms and abbreviations you might not be familiar
with. To help you better understand these terms weve provided
the following definitions:
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.
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.
Picocuries per liter (pCi/L)
- picocuries per liter is a measure of the radioactivity in water.
Nephelometric Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of
the clarity of water. Turbidity in excess of 5 NTU is just noticeable
to the average person.
Action Level (AL)
- the concentration of a contaminant which , if exceeded, triggers
treatment or other requirements which a water system must follow.
Maximum Contaminant Level
- 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 - 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.
FACTS
& FIGURES
The
City of Bedford Water Treatment System is required to test for
over 75 constituents to make sure that the water you drink is
safe. We are pleased to report that for the calendar year 1999,
the water delivered to your homes and businesses compiled with
all state and federal requirements. The regulated constituents
shown were detected in our finished drinking water as analyzed
between January 1 and December 31, 1999. Finished water is the
water that leaves our treatment plant and is distributed throughout
the system.

Special
Health Concerns
Infants
and young children are typically more vulnerable to lead in drinking
water than the general population. t is possible that lead levels
at your home may be higher than at other homes in the community
as a result of materials used in your homes plumbing. If
you are concerned about elevated lead levels in your homes
water, you may wish to have your water tested and flush your tap
for 30 seconds to 2 minutes before using tap water. Additional
information is available from the Safe Drinking Water Hotline
(1-800-426-4791).
Lead
in drinking water is rarely the sole cause of lead poisoning,
but it can add to a persons total lead exposure. All potential
sources of lead in the household should be identified and removed,
replaced or reduced.
As
you can see by the table, our system had no violations. Were
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
determine that your water is SAFE at these levels.
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.
Contaminants
that may be present in source water include:
- Microbial
contaminants, such as viruses and bacteria, which may come from
sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
- Inorganic contaminants,
such as salts and metals, which can be naturally-occurring or
result from urban runoff, industrial or domestic wastewater discharges,
oil and gas production, mining, or farming.
- Pesticides
and herbicides, which may come from a variety of sources such
as agriculture, urban stormwater runoff, and residential uses.
- Organic chemical
contaminants, including synthetic and volatile organic chemicals,
which are byproducts of industrial processes and petroleum production,
and can also come from gas stations, urban stormwater runoff,
and septic systems.
- Radioactive
contaminants, which can be naturally occurring or be the result
of oil and gas production and mining activities.
In
order to ensure that 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 establish 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
Agencys Safe Drinking Water Hotline at 1-800-426-4791.
MCLs
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.
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 (800-428-4791).
Thank
you for allowing us to continue providing your family with clean,
quality water this year. In order to maintain a safe and dependable

STEPS OF WATER TREATMENT
- Coagulation: Alum and other chemicals are added to water to
form tiny sticky particles called floc which attract
the dirt particles.
- Flocculation:
Slow mixing to allow floc to get
larger so it will gain weight and settle quicker.
- Sedimentation:
The heavy particles (floc) settle
to the bottom and clear water moves to filtration.
- Filtation:
The water passes through filters
that help to remove even smaller particles.
- Disinfection:
A small amount of chlorine is added
to kill any harmful bacteria or microorganisms that may be in
the water.
- Storage: Water is pumped to a closed tank or reservoir
where it flows through pipes to homes and businesses in the community.
