P.O. Drawer 807
Bedford, Virginia
Department of Water/Wastewater Treatment
2007 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 2007.
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 County 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.
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, 2007. 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.
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. The regulated constituents shown were detected in our finished drinking water as analyzed between January 1 and December 31, 2007. Finished water is the water that leaves our treatment plant and is distributed throughout the system.
