CONTAMINANT 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
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 storm
water 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 storm water runoff
and septic systems.
• Radioactive contaminants that can be naturally
occurring or the result of oil and gas production and
mining activities.
In
order to ensure that tap water is safe to drink, the
USEPA and the California Department of Public Health (CDPH)
prescribes regulations that limit the amount of certain
contaminants in water provided by public water systems.
Department regulations also establish limits for
contaminants in bottled water that must provide the same
protection for public health.
The
table (on the following page) lists all of the drinking
water contaminants that were detected from January 2007
through December 2007, unless otherwise noted. The
presence of these contaminants in water does not
necessarily indicate that the water poses a health risk.
The Department requires us to monitor for certain
contaminants less that 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, may be more
than one year old.
IMMUNO-COMPROMISED INDIVIDUALS
All
drinking water, including bottled water, can reasonable
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.
Some
people may be more vulnerable to contaminants in
drinking water that the general population. Immuno-compromised
individuals 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.
Additional information about contaminants and potential
health effects can be obtained by calling the USEPA’s
Safe Drinking Water Hotline (1-800-426-4791). The Office
of Ground Water and Drinking Water at EPA maintains a
web site with useful information on drinking. The
address is www.epa.gov/safewater/. Additional
information can be obtained by accessing the American
Water Works Association’s web site at www.awwa.org or
