Annual Drinking Water
Quality Report
May 2008
The City of Chubbuck is pleased to present its Water Quality Report for 2007. We are pleased to report
that our drinking water meets, or exceeds all federal and state drinking water standards. This report
contains important information about the quality of your drinking water. We are required to prepare and
distribute this Consumer Confidence Report. It is part of the requirements of the 1996 amendments to the
Safe Drinking Water Act. The City is committed to providing safe drinking water to its customers.
The City has attempted to make this report informative and readable. This report shows our water
quality and what it means. If you have questions about the report or your drinking water, please call the
City Public Works offices at (208) 237-2430, and further assistance will be provided. If you would like to
have input on how your drinking water is provided, you may either call the number above, or attend the City
Council meetings. The Chubbuck City Council meets at 7:30 P.M. every second and fourth Tuesday of
the month. The meetings are held in the City Offices located at 5160 Yellowstone Ave. Please feel free to
participate in these meetings.
Your drinking water comes from three wells drilled into the Lower Portneuf River Aquifer. They are
located throughout the city. This water is very high quality and is disinfected with chlorine before delivery
to your home. Well No. 4 does have a special treatment system. It is described below.
The only man -caused contaminant in the water is Tetrachloroethylene (PCE or PERC). The source
of PCE contamination is unknown at this time. We are able to treat the water using an air stripping process
to remove high concentrations of PCE.
The state has completed an assessment of our source water. That report is available for review at
the City Offices.
The City is pleased to report that our drinking water meets, or exceeds all federal and state
drinking water standards.
The City routinely monitors for constituents in your drinking water. Benchmark testing has also
been done for additional constituents. This is done in accordance with State and Federal laws. All
drinking water, including bottled water, may be reasonably expected to contain at least small amounts of
some constituents. It is important to remember that the presence of these constituents does not
necessarily pose a health risk. More information about contaminants and health effects can be obtained by
calling the EPA's Safe Drinking Water Hotline (800-426-4791) or http://www.epa.gov/safewater/hotline/.
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 microbial contaminants are available from the
Safe Drinking Water Hotline (800-426-4791)
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 before we treat it 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
storm water 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 by-
products 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 (FDA)
regulations establish limits for contaminants in bottled water which must provide the same protection for
public health.
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 other homes in the community
as a result of materials used 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).
Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of
age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly
for short periods of time because of rainfall or agricultural activity. If caring for an infant, you should ask
advice from your health care provider.
The table below shows the results of our water quality monitoring for the period January 1,
2006 to December 31, 2006. The state allows us to monitor for some contaminants less than once per
year because the concentrations of these contaminants do not change frequently. Some of our data,
though representative, are more than one year old. We have included test results for only those
constituents found in our drinking water. Most constituents tested for were not found. In the table, you will
find many terms and abbreviations you might not be familiar with. To help you better understand these
terms, we have provided the following definitions:
Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in
drinking water.
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below
which there is no known or expected risk to health. MCLG's allow for a margin of safety.
Non -Detects (ND): Laboratory analysis indicates that the constituent is not present.
Parts per Million (ppm) or Milligrams per liter (mg/1): 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 (ug/1): one part per billion corresponds to one
minute in 2000 years or a single penny in $10,000,000.
Picocuries per liter (pCi/L): measure of radioactivity in water
Million fibers per liter (MFL): measure of the presence of asbestos fibers that are longer than 10
micrometers.
Action Level: the concentration of a contaminant which, if exceeded, triggers treatment or other
requirements which a water system must follow.
