Annual Drinking Water Quality Report
(Village of Noble)
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 are committed to ensuring the quality of your water. Our water source is purchased from the City of Olney water department. Their source is a man made reservoir located just north east of the Olney city limits. This lake is named East Fork Lake. Their treatment facility is located on West Mack Ave. just to the outside of the Olney city limits.
In addition, due to the largest portion of this watershed area of their source supply being farm fields it is more likely that certain contaminants could be detected in this supply. Many tests are performed every year to ensure levels of contaminants remain below recommended levels.
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 Brad Kessler of the Village of Noble, at 723-2212. 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 village council meetings. They are held on 2nd and 4th Monday of each month beginning at 7:00 p.m. Within the Noble Village Hall.
The Village of Noble water department routinely monitors for constituents in your drinking water according to Federal and State laws. The first table shows the results of our monitoring for the period of January 1st to December 31st, 2010 Unless; If a date is listed under a level detected then that is the most recent testing done in accordance with e.p.a. regulations. The second table are results from samples collected from the city of Olney water department. 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 these tables 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 constituents is no 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.
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.
Parts per trillion (ppt) or Nanograms per liter (nanograms/l) – one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.
Parts pre quadrillion (ppq) or Picograms per liter (picograms/l) – one part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000.
Picocuries per liter (pCi/L) – picocuries per liter is a measure of the radioactivity in water.
Millirems per year (mrem/yr) – measure of radiation absorbed by the body.
Million Fibers per Liter (MFL) – million fibers per liter is a measure of the presence of asbestos fibers that are no longer than 10 micrometers.
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 – the concentration of a contaminant, which if exceeded, triggers treatment or other requirements, which a water system must follow.
Treatment Technique (TT) – (mandatory language) A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.
Maximum Contaminant Level – (mandatory language) 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 – (mandatory language) 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.

The state requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though correct, is more than one year old.
ABOUT THE DATA
What does this mean?
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.
“All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or is man made. Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials.”
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.
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 systems 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. USEPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the USEPA’s Safe Drinking Water Hotline (1-800-426-4791)
The sources of drinking water (both tap 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 can dissolve naturally occurring minerals and radioactive materials, and pick up substances resulting from the presence of animals or human activity. Possible contaminants consist of:
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 may be naturally occurring or result from urban storm water run off, 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 storm water run off, and residential areas.
ORGANIC CHEMICAL CONTAMINATES, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and may also come from gas stations, urban storm water run off and septic systems.
RADIOACTIVE CONTAMINANTS, which may 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, U.S.E.P.A. prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits from contaminants in bottled water, which must provide the same protection for public health
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.
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.
