This brochure is a snapshot of the quality of the water that we provided last year. Included are the
details about where your water comes from, what it contains, and how it compares to Environmental
Protection Agency (EPA) and state standards. We are committed to providing you with information
because informed customers are our best allies. It is important that customers be aware of the
efforts that are continually being made to improve their water systems. To learn more, please attend
any of the regularly scheduled meetings. For more information, please contact Raul Naranjo at

We add disinfectant to protect you against microbial contaminants. The Safe Drinking Water Act
(SDWA) requires states to develop a Source Water Assessment (SWA) for each public water supply
that treats and distributes raw source water in order to identify potential contamination sources. The
state has completed an assessment of our source water. For results of the source water assessment,
please contact us.
Message from EPA
Some people may be more vulnerable to contaminants in drinking water than the general population.
Immuno-compromised persons, such as those 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).
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 EPA’s Safe Drinking Water Hotline (800-426-4791).
The sources of drinking water (both tap water and bottled water) included 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 human activity.
Contaminants that may be present in source water before we treat it include:
Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants,
septic systems, agricultural livestock operations and wildlife.
Inorganic contaminants, such as salts and metals, 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 may come from a variety of sources such as storm water run-off, agriculture,
and residential users.
Radioactive contaminants can be naturally occurring or the result of mining activity
Organic contaminants, including synthetic and volatile organic chemicals, which are by-products of
industrial processes and petroleum production, may also come from gas stations, urban storm water
run-off, and septic systems.
In order to ensure that tap water is safe to drink, EPA prescribes regulation which limits the amount
of certain contaminants in water provided by public water systems. We treat our water according
to EPA’s regulations. Food and Drug Administration regulations establish limits for contaminants in
bottled water, which must provide the same protection for public health.
Our water system tested a minimum of 5 samples per month in accordance with the Total Coliform
Rule for microbiological contaminants. Coliform bacteria are usually harmless, but their presences in
water can be an indication of disease-causing bacteria. When coliform bacteria are found, special
follow-up tests are done to determine if harmful bacteria are present in the water supply. If this limit is
exceeded, the water supplier must notify the public by newspaper, television or radio.
“While your supplied water meets the EPA’s standard for Lead, if present at elevated levels this
contaminant 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. Your Water System 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 drinking 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.”
Water Quality Data
The tables below list all of the drinking water contaminants that were detected during the 2018
calendar year. The presence of these contaminants does not necessarily indicate that the
water poses a health risk. Unless noted, the data presented in this table is from testing done
January 1- December 31, 2018. The state requires us to monitor for certain contaminants less than
once per year because the concentrations of these contaminants are not expected to vary significantly
from year to year. Some of the data, though representative of the water quality, is more than one year
old. The bottom line is that the water that is provided to you is safe.
Terms & Abbreviations
Maximum Contaminant Level Goal (MCLG): the “Goal” is the level of a contaminant in drinking
water below which there is no known or expected risk to human health. MCLG’s allow for a margin
of safety.
Maximum Contaminant Level (MCL): the “Maximum Allowed” MCL is the highest level of a
contaminant that is allowed in drinking water. MCL’s are set as close to the MCLG’s as feasible using
the best available treatment technology.
Action Level (AL): the concentration of a contaminant that, if exceeded, triggers treatment or other
requirements that a water system must follow.
Treatment Technique (TT): a treatment technique is a required process intended to reduce the level
of a contaminant in drinking water.
Maximum Residual Disinfectant Level (MRDL): 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.
Maximum Residual Disinfectant Level Goal (MRDLG): the level of a drinking water disinfectant
below which there is no known or expected risk to health. MRDLG’s do not reflect the benefits of the
use of disinfectants to control microbial contaminants.
Non-Detects (ND): laboratory analysis indicates that the constituent is not present.
Parts per Million (ppm) or milligrams per liter (mg/l)
Parts per Billion (ppb) or micrograms per liter (µg/l)
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): a million fibers per liter is a measure of the presence of asbestos
fibers that are 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.
