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.
