Health Information
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 safe drinking water hotline (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. EPA/CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium
and other microbial contaminants are available from the Environmental Protection Agency’s safe drinking water
hotline (800-426-4791).

Educational Information
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 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
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.
• 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. FDA regulations establish limits for contaminants in
bottled water, which shall provide the same protection for public health.

Definition
Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or
other requirements which a water system must follow.
A Level 1 assessment is a study of the water system to identify potential problems and determine,
if possible, why total coliform bacteria have been found in our water system.
A Level 2 assessment is a very detailed study of the water system to identify potential problems
and determine, if possible, why an E. coli MCL violation has occurred or why total coliform
bacteria have been found in our water system, or both, on multiple occasions.
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.
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.
million fibers per liter
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.
Maximum residual disinfectant 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.

drinking water.

Detected Contaminants
Your water was tested for many contaminants last year. We are allowed to monitor for some contaminants
less frequently than once a year. The following tables list only those contaminants which were detected in your
water. If a contaminant was detected last year, it will appear in the following tables without a sample date. If the
contaminant was not monitored last year, but was detected within the last 5 years, it will appear in the tables below
along with the sample date.

Additional Health Information
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. Fontana Water Utility 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 www.epa.gov/safewater/lead.
