2004 ANNUAL DRINKING 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
2004. 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 in Bedford County, which is a surface water source. We have a
supplemental source located in Bedford that is used presently during periods of dry weather and could be utilized in the future as
demand increases. A source water assessment of our system was conducted in 2002 by the Virginia Department of Health.
The sources were determined to be of high susceptibility to contamination, using the criteria developed by the state in its
approved Source Water Assessment Program.
The assessment report consists of maps showing the source water assessment area, an inventory of known land use activities of
concern, and documentation of any known contamination within the last 5 years. The report is available by contacting your water
system representative at the phone number or address given elsewhere in this drinking water quality report.
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, 2004. 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. It’s 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 we’ve 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. - 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 2004, the water delivered to your homes and businesses complied 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, 2004. 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. It 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 home’s plumbing. If you are concerned about elevated lead
levels in your home’s 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 person’s 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. 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 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 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.
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 water supply
we sometimes need to make improvements that will benefit all of our customers. These improvements are sometimes reflected as rate structure
adjustments.
Thank you for understanding.
We at the City of Bedford Water Treatment System work around the clock to provide top quality water to every tap. 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.

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.
- Filtration: 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.
The Virginia Department of Health, Div. Of Drinking Water, City of Bedford’s local regulatory agency, has reviewed this Water Quality Report and
