Environmental Issues

Molds
are forms of fungi that are found naturally in the environment. Molds make tiny
spores to reproduce, just as some plants produce seeds. Indoors, these mold
spores move through the air and settle on surfaces. When mold spores land on a
damp spot, they may begin to grow and multiply. Molds need moisture and a food
source. Good food sources for molds are cloth, wood, wallboard and insulation,
but molds can grow on almost anything. When there is a wet surface or material
that is not dried or discarded promptly, molds can grow within 24 to 48 hours
in the area. Although some molds can produce toxins under certain conditions,
research so far has not shown what levels can clearly cause serious health
effects from indoor air exposure.

    
If mold is found in your home, testing is recommended and remediation process
by a professional is needed. Remediation process can be as little as cleaning
and repainting to complete removal or isolation. 

     Asbestos materials are commonly found in older homes, in pipe and furnace
insulation materials, roofing and siding tiles, floor tiles, millboard,
textured paints and other coating materials. Products banned – corrugated
paper, rollboard, commercial paper, speciality paper, flooring felt, and new
uses of asbestos. Products not banned – asbestos-cement corrugated sheet,
asbestos-cement flat sheet, asbestos clothing, pipeline wrap, roofing felt,
vinyl-asbestos floor tile, asbestos-cement shingle, millboard, asbestos-cement
pipe, automatic transmission components, clutch facings, friction materials,
disc brake pads, drum brake linings, brake blocks, gaskets, non-roofing
coatings, and roof coatings. Elevated concentration of airborne asbestos can
occur after asbestos containing materials are disturbed by cutting, sanding, or
other remodeling activities. Usually, it is best to leave asbestos material
that is in good condition alone. If asbestos material is more than slightly
damaged, or any changes in your home might disturb it, repair or removal by a
professional is needed.

    
It is best to leave asbestos material that is in good condition alone. If
asbestos material is more than slightly damaged, or any changes in your home
might disturb it, repair or removal by a professional is needed. Repair usually
involves either sealing or covering asbestos material. Sealing (encapsulation)
involves treating the material with a sealant that either binds the asbestos
fibers together or coats the material so fibers are not released. Pipe, furnace
and boiler insulation can sometimes be repaired this way. This should be done
only by a professional trained to handle asbestos safely. Covering (enclosure)
involves placing something over or around the material that contains asbestos
to prevent release of fibers. Exposed insulated piping may be covered with a
protective wrap or jacket.

     
Leaded paint is commonly found in older homes. Age of
property can indicate the amount of lead-based paint likely to be present and
the extent of lead hazard control work that may be necessary. Percentage of
buildings with lead-based paint are 90% for buildings built before 1940, 80%
for buildings built between 1940 and 1959, and 62% for buildings built between 1960
and 1979.
This paint could be on window frames, walls, the outside of
home, or other surfaces.

    
Leave lead-based paint undisturbed if is in good condition- do not sand or burn
off paint that may contain lead. If suspected material is flaking, sanded or
any changes in your home might disturb it, repair or removal by a professional
is needed.

     
Radon gas level readings vary depending on the geology under and near your home.
Radon is a naturally occurring radioactive gas produced by the breakdown of
uranium in soil, rock, and water. Air pressure inside your home is usually
lower than the pressure in the soil around your home’s foundation. Because of
this difference in pressure, the house acts like a vacuum, drawing radon in
through any cracks or openings on the floor. EPA recommends fixing the problem
if the radon test shows level of 4 pCi/L or higher.

    
Radon level can be reduced by several methods depending on the type of
foundations you have. Temporary fix such as by natural ventilation may cause
significant heated or cooled air loss. Better methods that can reduce from 30
to 99 percent of radon level are Subslab Suction (Subslab Depressurization),
 Passive Subslab Suction, Draintile Suction, Block-Wall Suction, Sump-Hole
Suction, Submembrane Depressurization in a Crawlspace, Natural Ventilation in a
Crawlspace, Sealing of Radon Entry Routes, Home (Basement) Pressurization, Heat
Recovery Ventilation, or HRV, and Private Well Water Systems Aeration.
