Q:
Where can I get my water tested?
A: All public drinking water supplies are tested daily
for microbiological and chemical / physical characteristics.
If you feel your water is unsafe to drink and are
concerned about your health, call your local health
unit they will be able to direct you to a private
location to have your water tested and answer any
questions.
Q:
How can I get my water tested?
A: If your home is served by a water system, get a
copy of your annual water quality report before you
test your water. This report will tell you what contaminants
have been found in your drinking water and at what
level. After you've read this report, you may wish
to test for specific contaminants (such as lead) that
can vary from house to house, or any other contaminant
you're concerned about. EPA does not test individual
homes, and cannot recommend specific laboratories
to test your drinking water. States certify water
testing laboratories. You may call your state certification
officer to get a list of certified laboratories in
your state. Depending on how many contaminants you
test for, a water test can cost from $15 to hundreds
of dollars.
Q:
When should I test?
A: Several factors will influence when and how often
you test your water. Where do get your water from?
Has that source changed? Have you done any plumbing
changes lately? Is there reason to believe that your
water is contaminated? Is there a sickness or illness
in your family affecting more than one person and
over a longer than normal time period? If you receive
your water from a "Public Supply", i.e.,
a municipal supply, or a supply that provides water
to more than 25 persons for 60 days per year (some
states are different, check with YOUR local water
department), you can be fairly certain that the water
supply is checked on a regular basis. The frequency
of the testing is based on the number of people served,
and may vary from more than once per week to once
per month, or even less. Under these conditions, test
when you move into a new residence to acquire a "base
line" of contaminant level, if any. Retest every
three years, unless you have reason to believe that
something has changed that could affect the quality
of your water.
If
you have a private well, you are the only person who
is responsible for the water your family drinks and
bathes in. We recommend testing by your local Health
Department every six months for Bacteria and Nitrate.
These two tests serve as indicators for other types
of contamination, that is not to say forget the other
tests; just that if you get a "bad" test
from them, you should also retest for the other types
of contaminants as well. Private wells should be tested
on a regular basis for Pesticides, Herbicides, Metals,
Organic and Inorganic chemicals and volatiles. Currently,
no laws govern the frequency of such testing, that
is why we say YOU are the only person responsible
for your family's water. We recommend an initial test
(for a base line), and then at least once per year.
Remember, one day after testing and finding "no
contaminants", your source could become contaminated.
Q:
What could I test for?
A: Coliform bacteria are a group of microorganisms
that are normally found in the intestinal tract of
humans and other warm blooded animals, and in surface
water. The presence of these organisms in drinking
water suggest contamination from a surface or shallow
subsurface source such as cesspool leakage, barnyard
runoff or other source. The presence of these bacteria
indicate that disease-causing (pathogenic) organisms
may enter the drinking water supply in the same manner
if preventive action is not taken. Drinking water
should be free of Coliform. Cysts and viruses are
microbiological contaminants, usually found in surface
water supplies. Giardia lamblia cysts can cause giardiasis,
a gastrointestinal disease. Another "bug"
getting a lot of attention lately, is cryptosporidium,
single-cell parasite measuring about 2 - 5 microns
in diameter. Many surface water supplies contain this
pest, which also comes from the intestine of warm
blooded animals. Nitrate in drinking water supplies
may reduce the oxygen carrying capacity of the blood
(cyanosis) if ingested in sufficient amounts by infants
under 6 months of age. This could cause a disease
called "methemoglobinemia", or "blue
baby" syndrome. The EPA has established a maximum
contaminant level (MCL) for nitrate at 10 mg/l (ppm)
measured as N. Unlike Coliform or other types of bacteria,
boiling the water will actually INCREASE the amount
of nitrate remaining in the water, increasing the
danger to infants. If you have high nitrate water,
either treat it with an approved treatment methodology
or find another source: Boiling will only make it
worse! Lead is now known to leach from older sweat
joints in copper pipe. As the water sits in the pipes,
small amounts of lead 'dissolve' into the water, contaminating
it. Lead is particularly harmful to small children
as they more rapidly absorb the toxic substance into
their systems. The EPA has estimated that more than
40 million U.S. residents use water that contains
more than the recommended levels.
Q:
Can I test my own water at home?
A: Not in a meaningful way. Simple kits are available
to test for hardness and some chemicals like chlorine
and lead, but a thorough analysis is not possible.
Your local water utility can provide you with information
on water quality and may test your water if you have
a question or complaint. The local and state health
departments can also provide water quality and testing
information.
Q:
When is it necessary to test drinking or recreational
water?
A: Every water supply should be regularly inspected
from source to distribution taps, and sampling should
be repeated under various seasonal conditions and
especially after heavy rainfalls. Concerned cottagers
should test lake water regularly to determine if septic
beds and boat grey water discharge is contributing
to bacterial contamination. Well water should be tested;
"
After well completion and disinfection (before the
well is used for drinking purposes);
" One to three weeks after (1) to confirm acceptable
results;
" When a well has not been in use for long periods
(seasonal residences); and
" Once or twice during the year, preferably after
a heavy rain or periods of snow melt.
Q:
How do you know if your drinking water is pure or
polluted?
A: You don't unless you have a current water analysis
performed regularly. Water quality is important for
all plants and animals, and the water analysis is
the most accurate way to determine if toxic metals
are present in your drinking supply. We have selected
one of the finest water testing labs in the USA to
perform the water analysis. It is a simple procedure
and one that we recommend for everyone concerned about
water quality.
Q:
How much sodium does ion exchange add to my water?
A: For every grain of hardness in your water, 7.5
mg of Sodium will be added to each quart of water
by the ion-exchange method. If you have water that
is 10 grains per gallon hard; you will add 75.0 mg
of Sodium per quart of water softened by ion-exchange.
To put that in perspective, one 8 oz glass of milk
contains 120 mg of Sodium, one slice of white bread
contains 114 mg of Sodium. You must also remember
that there is probably Sodium in the raw water, too.
If your city supply treats your water by a "hardness
reduction" treatment plant, you can be sure that
the Sodium level in your water has increased as a
result, how much? Call your plant operator and ask.
