What are molds?
Molds are one of the major forms of fungi. They
are
everywhere, both indoors and outdoors. They are
found
with decaying organic materials such as leaves
and
foods.How do molds
get into my home?
Molds are disseminated as microscopic spores.
They
are so small that they are easily blown through
the air.
Outside air contains 500-1,000 mold spores for
every
cubic meter of air.
Should I be concerned?
Our bodies are naturally equipped to handle
normal
levels of molds. Chronic exposure to mold
overgrowth in
the home and work place, however, can lead to
allergies,
sensitization, and more serious respiratory
ailments.
Individuals with compromised immune systems are
especially at risk. Additionally, conditions
favorable to the
growth of molds are also favorable for more
serious
infestations, such as wood decay fungi.
What should I look for?
Molds can be many different colors, but most are
green
to black. Look for dark discolorations on walls,
floors and
ceilings, especially in areas subject to
plumbing or roof
leaks. We are all familiar with the musty, moldy
odor of
these microorganisms. If you smell this in your
home,
there may be an infection present that you
cannot see.
The photograph below is an example of a serious
mold
infestation.

Mold and fungus can be a major problem for
seasonal homes that were built air tight
Can this be treated?
Yes. A 10% chlorine or hypochloride solution
will
eradicate most minor infections of mold. A
subsequent
treatment of mildicide and controlled moisture
will
eliminate the reocurrence of mold.
What are Wood Decay Fungi?

Where does asbestos come from?
Asbestos is a fibrous mineral that is mined from
the
earth in much the same way as coal. Asbestos may
be
present in pipe and boiler insulation, floor and
ceiling
tile, paper and textile products, plastics,
sealants,
cements, and brake linings. How can asbestos hurt my lungs?
Asbestos fibers are very small and invisible to
the
human eye. These fibers can enter the air you
breathe
when asbestos is disturbed by vibrating,
cutting,
sanding, or removing. Medical evidence suggests
that
exposure to airborne asbestos fibers can
increase your
risk of developing certain types of cancers and
noncancerous
respiratory diseases. Your lungs are the most
vulnerable to asbestos fibers. These fibers,
when
inhaled, can become trapped in the air sacs and
lead to
lung cancer, asbestosis, which is a fibrosis of
the
lungs, and cancer of the lung lining,
Mesothelioma. How is asbestos detected?
Testing is the only sure way of knowing if a
suspect
material contains any asbestos. Follow the
simple
directions of the test kit and you can be
assured of fast,
accurate results. A teaspoon sized sample is all
that’s
needed. This sample is then analyzed for
identification
of asbestos-containing material (more than 1%
asbestos fibers) in our laboratory using
state-of-the-art
instruments by our certified lab personnel. A
confidential
written report detailing the presence of
asbestos in your
sample is then promptly sent by return mail.
Are you planning a real estate
transaction?
If your home or office was built before the
mid-1970’s,
the testing of suspect building materials can
help
evaluate your environment for the presence of
asbestos.
Many states now require testing and
certification
that the home is asbestos free before a real
estate
transaction is completed. |
| Radon: |
Where does radon come from?
Radon comes from the natural breakdown
(radioactive
decay) of uranium. Radon can be found in high
concentrations
in soils and rocks containing uranium, granite,
shale, phosphate, and pitch-blende. Radon may
also
be found in soils contaminated with certain
types of
industrial wastes, such as the byproducts from
uranium
or phospate mining. In outdoor air, radon is
diluted to
such low concentrations that it is usually
nothing to
worry about. Once inside an enclosed space like
a
home, however, radon can accumulate. Indoor
levels
depend both on a building's construction and the
concentration of radon in the underlying soil.
How can radon hurt my lungs?
Radon itself naturally
breaks down into decay products
that adhere to dust and other particles in the
air, as well
as the lining of the lungs. As we breathe, these
particles
become trapped in the lungs, releasing small
bursts of
energy that damage lung tissue and begin the
uncontrolled
reproduction of cells known as cancer.
How does radon enter a
home?
Radon gas can seep
into a home through dirt floors,
cracks in concrete floors and walls, floor
drains, sump
pits, joints, and the pore of concrete-block
basement
walls. Radon can also enter a home via the water
of
private wells. As radon readily dissolves in
water, a
drinking source is easily contaminated in
uranium-rich
bedrock and soils.
How is radon detected?
Since you cannot see or smell radon, special
equipment
is needed to detect it. The method of collecting
radon is by absorption in carbon (charcoal)
within a
one-inch-deep canister. This charcoal canister
is the
detection device by which radon concentrations
are
measured. The charcoal canister is opened in the
lowest livable area of the home, exposed for
three days,
closed, and then returned to the laboratory by
mail for
processing. A confidential written report
detailing the
radon gas concentration within the home is then
promptly sent by return mail.
What is safe?
In certain specific situations, the US EPA and
the Center
for Disease Control have used a continuous
exposure
level of 4 pCi/l or 0.02 WL as a guidance level
at which
remedial actions is indicated.
The radon progenies, bismuth (Bi), polonium 210
(Po),
and lead 214 (Pb), have short half lives, which
produce
additional alpha particles that can damage lung
tissue.
It is these decay products, that account for
most of the
radiation received by human beings in most
situations
and are the primary sources of radon health
effects
such as lung cancer.
It is the exposure of the lungs to highly
charged alpha
particles that causes the adverse health risks
associated
with exposure to radon and radon decay products.
Since an alpha particle has low penetrating
power, the
particle’s own movement through the air and the
outer
layer of the skin provides protection to the
remainder of
the body from the radiation. Radon gas that has
been
ingested, such as with water, moves through the
body
at a rapid rate, thus having very little impact
on our other
internal organs.
Why charcoal test
canisters?
It is important for
prospective homeowners to get a
charcoal canister radon test conducted in their
prospective
home. While continuous radon monitors can show
radon levels in a home, they are calibrated
annually
whereas the instruments used to analyze charcoal
canisters are calibrated daily to accommodate
the
fluctuation in background radiation.
What is an alpha radon
monitor?
An alpha radon monitor
provides long-term testing
greater than 90 days with special film sensitive
to alpha
particles produced by radon.
Why use a continuous radon
monitor?
A continuous radon
monitor provides hourly test results
measuring radon, temperature, relative humidity,
and
movement. This is an ideal test procedure when
tampering may be suspected.

| Water
Quality: |
Why be concerned about
drinking water?
The Safe Drinking Water Act (SDWA) was passed by
Congress in 1974 and amended in 1986 and 1996.
It
protects public health by regulating the public
drinking
water supply. It does not regulate, however,
public water
systems serving fewer than 15 connections or 25
persons at least 60 days out of the year or
private wells
that serve fewer than 25 individuals. The SDWA
authorizes
the EPA to set national health-based drinking
water
standards to protect against naturally occurring
and
manmade contaminants. The EPA has set standards
for
90 chemical, microbiological, radiological, and
physical
contaminants in drinking water.
There are a number of problems
that can affect drinking water:
 | leaking underground
storage tanks |
 | improperly disposed of
chemicals |
 | animal wastes |
 | pesticides |
 | human wastes |
 | wastes injected deep
underground |
 | naturally occurring
substances |
 | water not properly
treated |
 | water that travels
through old or improperly maintained distribution
systems |
Private wells serving
fewer than 25 individuals are not required to be protected by the federal
standards. Therefore, those individuals need to make
sure their own drinking water is safe. The EPA recommends
testing a private well once per year to see if it
meets federal and state standards.
What questions should I ask?
 | Where does your water supply come from? |
 | Who is your water supplier? |
 | Has your water been tested recently? |
 | Is it tested regularly? |
 | How is it treated and protected from
contamination? |
 | Have water shortages occurred in your
community? |
 | Is your property close to an orchard,
farm, or golf course? |
 | Has your property formerly been used for agricultural purposes? |
 | What is safe? |
At present, the US EPA allowable level of
lead in drinking water is 50 parts per billion.
Within the next year they are planning to lower the allowable
concentration of lead to as low as 5 parts per billion. If
your water tests higher than the recommended limits, remedial
action may be necessary. It should be noted that
carbon filters, sand filters, and cartridge filters do not
remove lead from drinking water.
How can lead be detected in water?
Since you cannot see, smell, or taste lead
in water, testing is the only sure way of knowing if
your water contains lead. Both a “first draw” and a
“fully flushed” sample are needed. These samples are then
analyzed in our laboratory using state-of-the-art
instruments by our certified lab personnel. A confidential
written report detailing the lead concentration in water is
then promptly sent by return mail.
What other chemicals may be in my drinking water?
Although your drinking water may contain
many other metals, they may not all be harmful to you
(depending on amounts and EPA guidelines). Some water
tests available are
What are coliforms?
Coliforms are all aerobic (needing air) and
anaerobic (not needing air), gram negative, nonspore
forming, rodshaped bacteria that ferment lactose (a sugar) to
acid with gas within 48 hours at 35 degrees
centigrade.
What is e-coli?
E-coli are fecal coliforms. In the majority
of water supplies that fail a bacterial test, it is
rare to find the presence of e-coli. E-coli contamination of water usually is the
result of a direct contamination of the water supplie.
This contamination could be coming from livestock, a septic
tank or septic system, or an improperly sealed well.
How do coliforms get in our water supply?
As a water system ages, bacteria begins to
grow on the surfaces of the pipes or well. These are
common bacteria in the water. Occasionally, the bacteria
will detach from the surface and enter the water. Other ways
coliforms can get in the water are through surface
water infiltration and earthquake. Replacing a pump in a well
can disturb normally attached coliforms so that the
water will contain higher counts.
What should I do if I have e-coli in my water?
Having e-coli in your water means you have a
true contamination problem. The source of the
contamination must be found and its source removed. Then
the water can be treated.
What should I do if I have coliforms in my water? If you have coliforms in your water, such as
enterobacter cloacae, citrobacter freundii, klebsiella
oxytoca, and serratia, and no e-coli, most likely the
bacteria is naturally occurring in the water.
Nevertheless, if you have a well, you will need to see if there
are environmental causes for contamination. If you are on a
public water supply system, you will need to have
someone check out your water pipes and you should
also contact your public works department.

| Underground
Storage Tanks: |
Why investigate underground
storage tanks?
Leaking underground oil tanks are a threat to our water
quality and our health.
Many times tanks that are not in use still contain oil
that
is leaking into the soil and groundwater. The average
life expectancy of a residential UST is 12 to 15 years.
Who is responsible for the underground
storage tank cleanup if it leaks?
If the tank is leaking the
property owner will be ordered
by the New York State Department of Environmental
Conservation (DEC) to clean up all contamination of
water and soil. The DEC generally does not regulate
residential oil tanks because the bulk storage in most
homes is less than 1100 gallons.

Why does the DEC get involved?
If there are two tanks and the combined storage
capacity is 1100 gallons or greater, the tanks will need
to be registered with the DEC. If a tank has leaked, the
NYS DEC is the regulatory agency that monitors the
proper clean up and closing of the site.
What do I do if the tank is intact
and without contamination?
If the tank is still in use, it can continue to be used.
If the
tank is not in use it needs to be closed within one year
of when it stopped being used. A tank can be closed by
filling the existing tank in place with flowable fill or
having the tank removed from the ground and disposed
of according to the DEC regulations.
What do I do if the tank has
leaked?
The tank and all contaminated soil need to be
removed
according to the DEC STARS program regulations. The
homeowner should obtain a Closure Report pursuant
to applicable NYS guidelines and regulations.

Unless USTs are closed according to
regulations, there can be residual oil that can
contaminate soil and water
