Required Additional Health
Information
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 transplants, people
with HIV/AIDS or other immune system disorders, some elderly, and
infants may be particularly at risk from infection. These individuals
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 are available from the Safe Drinking Water
Hotline (800) 426-4791.
To ensure that tap water is
safe to drink, EPA prescribes limits on the amounts of certain
contaminants in water provided by public water systems. FDA regulations
establish limits for contaminants in bottled water. 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 at
(800)
426-4791.
The sources of drinking water (both tap 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 radioactive material, and can pick up
substances resulting from the presence of animals or from human
activity. Contaminants that may have been 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 resulting from
urban storm 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, storm water
runoff, and residential uses.
- Organic chemical contaminants,
including synthetic and volatile organics, 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, 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. FDA
regulations establish limits for contaminants in bottled water which
must provide the same protection for public health.
