The City of Bedford Water Treatment System is pleased to present to you this Annual Drinking Water Quality Report for 2005. 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.

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, 2005. 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. We are pleased to report that for the calendar year 2005, 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, 2005. Finished water is the water that leaves our treatment plant and is distributed throughout the system.
