We are pleased to present this year's Annual Water Quality Report (Consumer
Confidence Report) as required by the Safe Drinking Water Act (SDWA). This
report is designed to provide details about where your water comes from, what
it contains, and how it compares to standards set by regulatory agencies. This
report is a snapshot of last year's water quality. We are committed to
providing you with information because informed customers are our best allies.
Last year, we conducted tests for over 80 contaminants. We only detected 1 of
those contaminants, and found only 1 at a level higher than the EPA allows. As
we informed you at the time, our water temporarily exceeded drinking water
standards. (For more information see the section labeled Violations at the end
of the report.)
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/Centers for Disease
Control (CDC) guidelines on appropriate means to lessen the risk of infection
by Cryptosporidium and other microbial contaminants are available from the Safe
Water Drinking Hotline (800-426-4791).

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 water poses a health risk. More information about
contaminants and potential health effects can be obtained by calling the
Environmental Protection Agency's (EPA) 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:
microbial contaminants, such as viruses and bacteria, that 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 stormwater 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; and 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 that 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.

If present, elevated levels of lead can cause serious health problems,
especially for pregnant women and young children. Lead in drinking water is
primarily from materials and components associated with service lines and home
plumbing. USDA Chilao Main A-9 is responsible for providing high quality
drinking water, but cannot control the variety of materials used in plumbing
components. When your water has been sitting for several hours, you can
minimize the potential for lead exposure by flushing your tap for 30 seconds to
2 minutes before using water for drinking or cooking. If you are concerned
about lead in your water, you may wish to have your water tested. Information
on lead in drinking water, testing methods, and steps you can take to minimize
exposure is available from the Safe Drinking Water Hotline or at
http://www.epa.gov/safewater/lead.
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of contaminants in water provided by public water systems. The table below lists all of the drinking water contaminants that we detected during the calendar year of this report. Although many more contaminants were tested, only those substances listed below were found in your water. All sources of drinking water contain some naturally occurring contaminants. At low levels, these substances are generally not harmful in our drinking water. Removing all contaminants would be extremely expensive, and in most cases, would not provide increased protection of public health. A few naturally occurring minerals may actually improve the taste of drinking water and have nutritional value at low levels. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not vary significantly from year to year, or the system is not considered vulnerable to this type of contamination. As such, some of our data, though representative, may be more than one year old. In this table you will find terms and abbreviations that might not be familiar to you. To help you better understand these terms, we have provided the definitions below the table.

Important Drinking Water Definitions |
|
|
Term |
Definition |
|
MCLG |
MCLG: Maximum Contaminant Level Goal: 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. |
|
MCL |
MCL: Maximum Contaminant Level: 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. |
|
TT |
TT: Treatment Technique: A required process intended to reduce
the level of a contaminant in drinking water. |
|
AL |
AL: Action Level: The concentration of a contaminant
which, if exceeded, triggers treatment or other requirements which a water
system must follow. |
|
Variances
and Exemptions |
Variances and Exemptions: State or EPA permission not to
meet an MCL or a treatment technique under certain conditions. |
|
MRDLG |
MRDLG: Maximum residual disinfection level goal. The level
of a drinking water disinfectant below which there is no known or expected
risk to health. MRDLGs do not reflect the benefits of the use of
disinfectants to control microbial contaminants. |
|
MRDL |
MRDL: Maximum residual disinfectant level. The highest
level of a disinfectant allowed in drinking water. There is convincing
evidence that addition of a disinfectant is necessary for control of
microbial contaminants. |
|
MNR |
MNR: Monitored Not Regulated |
|
MPL |
MPL: State Assigned Maximum Permissible Level |
