Celebrating Earth Day (Part 1 of 2)

Today we are going to take a look at some things your family can do to celebrate Earth Day on April 22nd. In our next post, we will explore options for ways that businesses can participate in Earth Day.

What is Earth Day?

The first Earth Day was started by Senator Gaylord Nelson and celebrated on April 22nd, 1970 in San Francisco CA. Establishment of the Environmental Protection Agency (EPA) followed during that same year. The concept of Earth Day went international in 1990 and now celebrations are coordinated by the Earth Day Network in over 175 countries.

What is Special About this Year?

In recognition of the power of millions of individual actions, Earth Day 2011 will be organized around A Billion Acts of Green®: Personal, organizational and corporate pledges to live and act sustainably. The goal is to register one billion actions in advance of the Earth Summit in Rio in 2012. You can learn more about this initiative at http://www.earthday.org.

How Can Your Family Make a Difference?

Earth Day is a day to reflect on our planet, our environment, our resources and what we can do to help keep them healthy for generations to come. There are so many simple things that families can do to lessen their impact on the environment on Earth Day and throughout the year.

A few ideas are:

•Buy local produce in season. Take a trip to a farmer’s market. Children are more likely to eat fruits and vegetables if they help pick them out. Better yet – plant your own garden!
•Help clean up your favorite park, beach, or neighborhood. Talk about the importance of not littering, pouring things into storm water drains, or leaving pet waste on the ground.
•Change from incandescent to compact fluorescent light bulbs now. It will soon be required.
•Conserve water by taking showers versus baths, installing low flush toilets, and planting native species shrubs and flowers that are more tolerant of dry conditions.
•Reduce the amount of time driving in your car. Walk or ride bikes for neighborhood errands. Carpool when you can. Consider parking your car and taking the bus occasionally.
•Avoid plastic shopping bags – carry and use canvas shopping bags. Remember to take them every time you shop and not just to the grocery store. Buy in bulk or choose items with reduced packaging when possible.
•Unplug appliances when they are not in use – coffee makers, toasters, phone chargers, hair dryers, etc. all continue to consume energy simply by being plugged in.
•Wash clothes in cold water.
•Make an effort to significantly impact your family’s waste this year. Reducing your consumption, recycling more, and composting are easy ways to get a big jump start.

Conflict of Interest?

A conflict of interest is defined as a situation that has the potential to affect the impartiality of a person. This most commonly occurs in a business setting when an individual is involved in multiple interests, one or more of which has the potential to corrupt the motivation for performance in the other.

You have heard the old parables of the fox guarding the hen house or the wolf watching the sheep. The basic lesson in both is "Don't assign a job to someone who will then be in a position to exploit it for his own ends”.

There are regulations in place throughout the lead and asbestos industries to address the potential conflict of interest associated with confirming the presence of these contaminants, and then being in charge of the proper removal and disposal of them.

However, a review of mold remediation companies on any search engine or in the yellow pages shows that many of them also perform mold assessments or mold testing. Is this a conflict of interest? It would seem that at least two states think so.

Currently, Texas and Florida both require licensing throughout the mold industry. The legislation in both TX and FL clearly states that “A licensee shall not perform both mold assessment and mold remediation on the same project, or have an ownership interest in an entity that performs mold assessment services and mold remediation services on the same project.”

An Orlando FL contractor was recently arrested and now faces charges of grand theft and insurance fraud for collecting samples that were never analyzed. In addition, he provided fake lab data to support the need for extensive mold remediation - which he then also performed.

Another popular scam is to offer FREE mold inspections and sampling. Done properly, mold assessment and testing requires an investment of time, equipment, testing media and professional knowledge.

The only way a company can afford to continue to offer this assessment and testing service for free is to make a larger profit from remediating any mold problems that are found.

In no way does Air Matters LLC feel that these two examples are the norm. Many mold remediation companies are owned by hard working, ethical people who are hoping to keep some services in house to increase their profit margin and streamline the project.

However, more and more consumers are questioning the potential for conflict of interest, leading many remediation contractors to partner with third party providers.

Air Matters LLC has specialized in confirming the presence and identity of fungal species in homes and businesses since 2002. We do not perform any remediation work, “So you can breathe easy” knowing that you are getting an unbiased evaluation each and every time.

Flood Damage Leads to Mold Problems

Last week, a large portion of North Carolina experienced record-setting rain falls. Many areas in Eastern NC experienced flooding, including the town of Windsor in Bertie county, where homes and businesses contained several feet of water.

Federal Emergency Management Association (FEMA) crews visited the town of Windsor earlier this week, and the mayor is hoping for a federal disaster declaration. That declaration would provide federal funding and manpower to help the citizens clean up and get back on their feet from the largest disaster since Hurricane Floyd, which hit in September of 1999.

"Everybody is just going through the same routine," says Ted Shaw, a business owner in Windsor. "Got all the carpet up and out on the street. Sunday we came in and bleached and took the garden hose and washed all the water out to the street," says Shaw.

Are Ted Shaw and other residents of Windsor doing the right thing during their clean up?

The Environmental Protection Agency (EPA) has a publication titled "Flood Clean Up and the Air in Your Home" designed to help home and business owners prevent indoor air quality problems associated with flooding and flood water contamination.

This is a simple booklet that outlines steps for cleaning up safely after a flood, including use of the proper personal protective equipment. It also provides a list of resources where you can find additional fact-based information on flooding, clean up, mold and other related issues.

You can access a copy of the publication at http://www.epa.gov/iaq/flood/flood_booklet_en.pdf

MiST™ My Ride?

While I was waiting for my new tires to be installed the other day, a brochure on the counter caught my eye. . .

"A tidy car isn't free of mold, germ, and bacteria. A MiST™ Service is like a hand sanitizer for the vents & interior surfaces of your car. Get a MiST™ Service Today! You owe it to yourself and your family." Intrigued, I turned it over.

There was a magnified picture of a cultured sample taken from the interior of a Porshe, along with an illustration of streams of things coming from your car vent. Below these in bold print it said "Every time the fan is turned on, harmful spores are blown into the air you and your passengers breathe."

According to the EPA, some service providers may attempt to convince you that your air ducts are contaminated by demonstrating that the microorganisms found grow on a settling plate (i.e., petri dish). This is inappropriate. Some microorganisms are always present in the air, and some growth on a settling plate is normal. As for the "harmful spores" statement, only an expert can positively identify a substance as biological growth and lab analysis is normally required for final confirmation.

Upon visiting the company's website, you learn that "MiST™ utilizes atomized micro-droplets (1/10 the size of aerosol droplets) of a specially formulated solution. These droplets are drawn into an automobile's vents, penetrating and traveling to where the micro-organisms are living. MiST™ treats the entire ventilation system, including the evaporator, heater core, air ducts and passenger compartment surfaces." The company suggests that you perform this service every 6 months.

It does not say if the specially formulated solution includes water. If so, introducing this additional moisture into the system may actually promote fungal growth. Also, the EPA cautions about the use of biocides inside air ducts. They say that simply spraying or otherwise introducing these materials into the operating duct system may cause much of the material to be transported through the system and released. Depending on the product used, it may actually be more dangerous to breathe.

The company does suggest regular cleaning of your vehicle and maintenance of your filter system, both of which are important to minimize irritating contaminants.

Although this EPA document focuses on the air ducts in your home, many of the issues are the same. Read what they say at: http://www.epa.gov/iaq/pubs/airduct.html, and then decide if you want to MiST™ your ride!

The Most Frightening Fungus?

Type "Black Mold" into an internet search engine, and what do you get? Links to over 5.5 Million pieces of information in less than a quarter of a second.

WOW! The majority of these sites refer to Stachybotrys. It is commonly nicknamed “stachy” and has been sensationalized as "black mold" or "toxic mold" by the media.

What is Stachybotrys?

Stachybotrys Chartarum is the single best known species of the genus. Despite the "black mold" nickname, Stachybotrys is not truly black, but is normally greenish-black in color. It tends to be somewhat slimy, as opposed to powdery. It thrives on on cellulose-containing products that have been wet for several days or more and enjoys a fairly constant moisture source.

Why are People so Worried About Stachybotrys?

Stachbotrys is known to produce trichothecene mycotoxins. Mycotoxins may enter the human body through ingestion, inhalation, or absorption through the skin. Exposure to these mycotoxins may have potential health effects for some individuals including coughing, wheezing, runny nose, irritated eyes or throat, skin rashes, and diarrhea.

Since these symptoms are general in nature, they also can be caused by a cold, virus or exposure to other allergens. It is not known what level of mycotoxin from Stachybotrys must be present in the air to cause health effect symptoms.

People with allergies may be more sensitive to Stachybotrys, as well as other molds. People with immune suppression or underlying lung disease are more susceptible to fungal infections that may be associated with mycotoxins.

Is the Concern About Stachybotrys New?

The potential effects of Stachybotrys toxins were first observed in cattle and horses in Russia in 1920. Stomatitis, rhinitis, conjunctivitis, pancytopenia and neurological disorders developed in these animals after they ingested hay contaminated with Stachybotrys.

Later in the 1970s, it was claimed that Yellow Rain attacks in Southeast Asia were associated with the use of aerosolized trichothecenes as an agent of biologic warfare. However, this claim remained scientifically unproven.

What Caused the More Recent Focus on Stachybotrys?

In 1994, the U.S. Centers for Disease Control and Prevention (CDC) investigated whether exposure to Stachybotrys might be related to pulmonary hemorrhage, also known as bleeding lungs, in infants in Cleveland, Ohio.

While the CDC initially concluded that there was a possible link between exposure to the mold and the condition, Stachybotrys was not found in the homes of seven children with bleeding lungs identified in the Chicago area between April 1992 and January 1995.

A subsequent review of the Cleveland study by a group of CDC experts concluded that a link between exposure to Stachybotrys and bleeding lungs in infants was not proven.

Where Can I Get More Information?

If you want additional information on Stachybotrys, make sure you are using reputable sources that provide the facts rather than relying on scare tactics.

Several good places to start include the Environmental Protection Agency (www.epa.gov/mold) and the Centers for Disease Control (www.cdc.gov/MOLD/stachy.htm).

EPA Teams with Building Industry Experts on Comprehensive IAQ Guide

Too often, indoor air quality (IAQ) problems result from poor planning, improper design, or inadequate construction methods and materials. If design and construction teams work together to incorporate good IAQ strategies from the start, many of the common pitfalls can be avoided.

The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a collaboration between the American Society of Refrigerating, Heating and Air Conditioning Engineers (ASHRAE), the American Institute of Architects, the Building Owners and Managers Association International, the United States Environmental Protection Agency (EPA), the Sheet Metal and Air Conditioning Contractors of North America, and the United States Green Building Council, which awards the internationally recognized LEED green building certification system.

The book outlines specific strategies for achieving eight critical IAQ objectives relative to moisture management, ventilation, filtration and cleaning, and source control.

A 198-page summary of the guide can be downloaded free of charge at www.ashrae.org/iaq. The full publication, including a CD, is also available through ASHRAE for $29.

Within the summary, Objective 2 - Control Moisture in Building Assemblies and Objective 4 - Control Moisture and Contaminants Related to Mechanical Systems offer strategies to limit water and moisture intrusion, which directly impact the growth of fungal (mold) species.

The summary guide states in Objective 2 that "Moisture in buildings is a major contributor to mold growth and the poor IAQ that can result. Wetting of building walls and rainwater leaks are major causes of water infiltration."

There is also significant attention in this section given to controlling indoor humidity levels. High humidity supports the growth of mold, dust mite populations, and other biological contaminants indoors that may cause allergies or other health problems for building occupants.

Low humidity levels can dry out mucous membranes. Either way, "humidity conditions also affect people's perceptions of the IAQ."

Objective 4 starts out explaining the important role of mechanical systems in providing good IAQ. It then states "However, since many mechanical systems carry water or become wet during operation, they can also amplify and distribute microbial contaminants." Detailed strategies are discussed for each component of the mechanical systems.

Considering IAQ from the initial design process through the building occupancy will ensure that everyone breathes a little easier.

Are You Suffering from Sick Building Syndrome?

"Sick Building Syndrome" is a term that is used to describe when somebody experiences health or personal comfort effects that seem to be linked to the amount of time spent in a particular building, but they are unable to positively identify a specific cause or health condition responsible for these effects.

These effects may only be felt when in one particular room or area of a building, or they may be experienced throughout the facility. Also, they may be limited to one individual or can affect a large number of building occupants.

The complaints differ and can include many symptoms such as headaches; dry, itching, red or watery eyes; sensitivity to odors; coughing; dry or itchy patches or skin including rashes; dizziness; nausea; or fatigue.

Two things that do seem to be consistent with Sick Building Syndrome are the fact that an immediate cause of the symptoms is not known and that people who are suffering report a relief from these symptoms once they are away from the building.

According to the Environmental Protection Agency (EPA), the following factors are often responsible for causing or contributing to complaints of Sick Building Syndrome:

1. Biological Contaminants
This includes mold, mildew, bacteria, pollens, and insect or bird droppings. These contaminants may breed in stagnant water that has collected around building leaks or in ducts, drain pans, or humidifiers.

2. Indoor Chemical Contaminants
Adhesives, carpeting, upholstery (including fabric cubicle walls), manufactured wood products (particularly press board), copy machines, pesticides, cigarette smoke, and cleaning products may all emit volatile organic compounds (VOC's), including formaldehyde.

3. Outdoor Chemical Contaminants
The outdoor air that enters a building, particularly through poorly positioned air intake vents, doors or windows can also be a source of chemical pollution. Common contaminants may include motor vehicle exhausts, plumbing vents, kitchen fumes, or bathroom exhausts.

4. Inadequate Ventilation
Energy conservation measures and construction methods have resulted in buildings today being more tightly sealed than ever before. As a result, there has been a decrease in the outdoor air exchange. Inadequate ventilation may also occur when the HVAC system is not properly sized, balanced or maintained for the square footage and type of occupancy intended and is unable to effectively distribute conditioned air to the occupants of the building.

A professional indoor air quality investigation is one tool to help identify potential risk factors that may be contributing to symptoms of Sick Building Syndrome.

Resolve to Improve Your Indoor Air Quality in 2010!

So, we are a little half way through January. How are those New Year's resolutions going? Eating right, exercising more, getting enough sleep every night. . . you know these things are good for you. That doesn't make them easy. Breathing -- now that's easy. But what about monitoring what you are breathing into your body each day? That's a little tougher!

The toxins that you breathe in every day (air quality) often go unnoticed simply because they are invisible. Things that are invisible (unlike smoking cigarettes, really bad for you foods, and toxic friends) are easy to overlook. The Kingston Whig Standard offers these tips for improving your personal air quality today:

1. Quit smoking. Cigarette smoke contains known carcinogens (cancer-causing agents) and a host of chemicals. If you can't quit just yet, be sure to smoke outdoors. (NOTE: In North Carolina restaurants and bars, you have no choice but to smoke outdoors. Yeah!!)

2.Change furnace filters monthly. Reduce the dust and allergens in the air by changing your furnace or air conditioning system filters on a monthly basis. Also vacuum intake vents. You can consider having ductwork cleaned by a professional service, too. (NOTE: Air Matters LLC recommends you review the following document published by the Environmental Protection Agency prior to having your ducts cleaned. http://www.epa.gov/iaq/pubs/airduct.html)

3. Fill the house with plants. Plants naturally filter the air and give off fresh oxygen. Plus, they're nice to look at!

4. Avoid pressboard furniture. Many composite wood products contain formaldehyde and other chemicals. These can sneak into the air over time.

5. Use all-natural cleaners. Chemical-laden cleaners don't simply smell strongly, they can actually be very harmful if breathed in. Also, never mix cleaning products (such as bleach and ammonia). It can produce a toxic gas. Lemon juice, vinegar, baking soda, and other all-natural items can be used as very effective cleaners.

6. Vacuum carpets regularly. Carpets and fabrics can harbor dust and other allergens. Some newer carpets are created to reduce allergens, but most carpets should be cleaned two to three times a week, primarily in high-traffic areas and in homes with pets. (NOTE: Air Matters LLC recommends that you invest in a HEPA-vacuum.)

7. Eliminate leaks. Drippy faucets or a damp basement can lead to the growth of mold and mildew. While many types of these fungi are harmless, there are some that are very harmful if breathed in. If you have a mold or mildew problem, call in a professional for a threat assessment and advice on proper cleaning. (NOTE: If you want to confirm the presence and identity of fungal species, that would be Air Matters LLC. . .)

8. Test for hidden dangers. Radon, carbon monoxide, and asbestos could be lurking in your home. Testing eliminates threats and can safeguard your family.

9. Call in a cleaning crew. Regular cleaning can limit the amount of particles floating around in the air. Keeping the house spic-and-span is a way to clean the air as well. Having a regular cleaning service come in can be a way to fit a thorough cleaning into your busy schedule.

10. Dial down the humidity. Run the exhaust fans in bathrooms and invest in a dehumidifier. Mold and mildew, as well as dust mites, thrive in moist conditions.

11. Launder sheets and pillowcases every 10 days. Buy machine- washable pillows and bed linens.

12. Kick out pests. Allergens from roaches are a major cause of asthma, and airborne protein from dried rodent urine is a potent allergen.

13. Air it out. On low-particulate days, throw open the windows and let the fresh air in.

14. Check the venting. All appliances should be properly vented. Make sure vents are free of obstructions. Appliances should be serviced according to the manufacturer's maintenance schedule to avoid combustion byproduct buildup and reduce dust and particulate accumulation.

Resolve to improve the indoor air quality in your home, and you can breathe easier in 2010!

Check for Mold Before Buying Foreclosures

The American economy is still reeling from the recession, and the housing market remains one of the hardest hit areas. As foreclosures continue to mount, many of those who do have cash to spare are looking to invest in bargain real estate.

However, bargain hunters need to beware of potential unseen problems that could quickly drain their profits -- including hidden mold. Home owners who were foreclosed upon likely did not have the money to perform routine repairs and maintenance, which may have grown into larger problems. In addition, foreclosed properties may have been vacant for some time and many issues may have gone unnoticed.

RIS Media, a well-known source for news and information in the real estate industry, offers these 10 trouble spots to consider when purchasing a foreclosed home:

These 10 Signs May Indicate That Trouble is Around the Corner

1. Unheated house in winter months. If the home has been properly winterized, there's no need for heat. But if the home has not been properly winterized, pipes will burst and cause water damage.

2. Missing sinks, toilets and other fixtures. Make sure they've been properly removed and not ripped from walls and floors.

3. Peeling, bubbling, and discolored paint; swelling in walls or ceilings (especially around kitchens and bathrooms) or a musty odor all indicate water damage and, potentially the presence of moisture and mold.

4. Fungus growth inside cabinets, behind drawers and built-ins. Fungus could mean that there has been water damage. Since water falls down, look for a source above the mold.

5. Blocked drains or pipes will cause future problems and may have already created sewage backups.

6. Black cobwebs, greasy gray residue on walls and/or a strong oily odor. This could point to potential soot damage or a malfunctioning furnace.

7. An older home with extensive renovations. Check with the city for pulled permits in order to get remodeling details. If asbestos is present and has been disturbed, be sure it's been remediated by a certified specialist.

8. Excessive painting of every nook, cranny, door and floor may mean that the seller is covering up mold.

9. Discolored sub flooring. From the basement, check the sub flooring above for stains and small holes, both caused by mold.

10. Air Quality. The air quality within a home tells a lot about the home's condition. Be sure to include air an surface testing in your home inspection. It's a few hundred dollars well spent!

Stricter Rules on Radon Tied to Lung Cancer

The World Health Organization (WHO) has significantly lowered their guidelines on how much radon is permissible in homes without leading to adverse health effects. Their new "Handbook on Indoor Radon" issued September 22 called for public health authorities and the construction industry to reduce exposures to radon, calling it a "major and growing public health threat in homes". Radon is widely considered to be a leading cause of lung cancer, second only to smoking.

What is Radon?
Radon is a gaseous radioactive element that people cannot see, smell or taste. It occurs naturally through the decay of uranium in the soil. According to the Environmental Protection Agency (EPA) the average home indoor radon level is about 1.3 picocuries per liter (pCi/L) in the United States. The average outdoor level is about 0.4 pCi/L.

How Does Radon Get Into Your Home?
Radon is most common in homes with basements, where it seeps in from the soil and through the walls. However, many homes without basements also have radon problems. The amount of radon that escapes from the soil into the home can depend on the soil composition, soil moisture, and building construction. In some cases, radon enters the home through well water.

How Much Radon is Acceptable?
The EPA's recommended exposure level is 4 pCi/L, which has been their standard for 40 years. WHO's new standard is more restrictive, only allowing for 2.7 pCi/L. WHO strongly emphasizes the importance of radon testing by all home owners or buyers looking to purchase a home. WHO studies indicate that most radon induced lung cancers occur from exposure to low and medium doses of radon in residential structures.

Should You Be Concerned About Granite Countertops?
Some people attribute a rise in radon to the widespread use of granite in today's home. The EPA believes the principal source of radon in homes is from the soil in contact with basement floors and walls. While natural rocks such as granite may emit radiation and radon gas, the levels attributable to such sources are not typically high.

What Are the Health Effects of Radon?
Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked. Dr. Richard H. Carmona, the U.S. Surgeon General, issued a national health advisory on radon.

For additional information on radon in North Carolina, contact the NC Department of Environment and Natural Resources NC Radon Program at http://www.ncradon.org/.

Should You Have the Air Ducts in Your Home Cleaned?

Summer in North Carolina means two things: heat and humidity. Maybe the air conditioner in your home has not been able to keep up, so you call your regular HVAC servicing company. One of the things they might suggest is having your duct work cleaned to remove dust and mold spores and improve the air flow into your home. Is this really necessary?

Despite the claims of many companies that perform duct cleaning, it has never been proven to have any substantial health benefits. Addressing the other pollutants in your home such as cooking, cleaning products, smoking, or pets can often have a more immediate impact on the air quality inside your home.

What if the service provider tells you that your ductwork or your HVAC system is contaminated with mold?

Always ask to see it. Many areas within the HVAC system or ducts are not easily accessible. Even if you see a substance that you suspect is mold, remember that positively identifying mold requires testing and laboratory analysis. Mold on hard non-porous surfaces (such as sheet metal) can be cleaned, while contaminated insulation or other such materials will need to be replaced.

However, there are times when duct cleaning may be beneficial. You should consider having your air ducts professionally cleaned if:

• you can see large accumulations of suspected (or confirmed) mold growth
• there is an infestation of rodents or insects evident inside the ductwork
• visible discharge is emitted from your air supply vents when the system is running

If you determine that having the air ducts in your home cleaned is necessary, here are some tips from the Environmental Protection Agency on selecting a service provider :

• Do not hire duct cleaners who make sweeping claims about the health benefits of duct cleaning -- such claims are unsubstantiated. Do not hire duct cleaners who recommend duct cleaning as a routine part of your heating and cooling system maintenance. You should also be wary of duct cleaners who claim to be certified by EPA. EPA neither establishes duct cleaning standards nor certifies, endorses, or approves duct cleaning companies.
• Do not allow the use of chemical biocides or chemical treatments unless you fully understand the pros and the cons of the products being used.
• Check references to be sure other customers were satisfied and did not experience any problems with their heating and cooling system after cleaning.
• Contact your county or city office of consumer affairs or local Better Business Bureau to determine if complaints have been lodged against any of the companies you are considering.
• Interview potential service providers to ensurethat they are experienced in duct cleaning and have worked on systems like yours; they will use procedures to protect you, your pets, and your home from contamination; and they comply with the National Air Duct Cleaning Association's air duct cleaning standards.
• Ask the service provider whether they hold any relevant state licenses. The following states require air duct cleaners to hold special licenses: Arizona, Arkansas, California, Florida, Georgia, Michigan and Texas. Other states may soon require them as well.
• If the service provider charges by the hour, request an estimate of the number of hours or days the job will take, and find out whether there will be interruptions in the work. Make sure the duct cleaner you choose will provide a written agreement outlining the total cost and scope of the job before work begins.

Finally, remember that the best way to avoid needing to have the air ducts in your home cleaned is to prevent dirt and water from entering your heating and cooling system.

What You Should Know About Mold

What is mold?
Molds (and mildew) are forms of fungi that are found everywhere – inside and outside. Fungi are necessary for recycling organic material, which is required to sustain plant and animal life. There are more than 100,000 types of mold. These species can be any color, including white, orange, green, brown or black. The most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria. Fewer than 200 species of molds have been classified as human pathogens that can cause infections.

How does mold get inside my house?
Many molds grow naturally in the indoor environment. Mold spores may enter your house through open doorways, windows, or HVAC systems. Spores may attach themselves to family members, pets, clothing, shoes, or bags and be brought indoors.

How does mold grow?
Mold reproduces by releasing tiny spores. These spores settle on surrounding surfaces, and begin to grow in favorable conditions. Growth requires three things: moisture, an organic food source (examples include carpet, sheetrock, wallpaper, paint, upholstery, wood, leather, or even dust) and a suitable temperature between 40-100 degrees Fahrenheit. It is important to note that mold does not need light to grow. When one of the three conditions becomes unsatisfactory, the mold becomes dormant. It can resume activity when the conditions are restored to favorable.

What is the “killer mold” or “black mold” I have heard about?
Sensationalized media reports refer to a specific type of mold called Stachybotrys that has been nicknamed the “killer mold” or “black mold”. It is less common than other mold species. There are only a few molds that are truly black, although many can appear black. Not all mold that appears to be black is Stachybotrys. This specific type of mold grows on cellulose materials, such as paper, cardboard, sheetrock, or framing. It requires a very high, constant moisture level to grow, which usually occurs after something has been wet for several weeks. Stachybotrys can release potentially toxic substances called mycotoxins, which cling to the mold spores. The health effects of these toxins are unproven and are currently being studied.

How do I know if I have mold?
In many cases, visible mold growth will allow you to confirm the presence of mold in your home. Mold may also be hidden on the backside of sheetrock or wallpaper, the underside of carpet and padding, inside ductwork, or around pipes. Musty, moldy odors may also be an indication of hidden mold. Investigating hidden mold usually requires disturbing the mold growth site. This can lead to a massive release of mold spores, so you should consider hiring a professional if you suspect you might have hidden mold.

How do I get rid of mold?
Beware of companies who claim they can totally eliminate mold from your home. More than 1,000 different kinds of indoor molds have been found in US homes, and it is impossible to get rid of all the mold in your home. The concern is around the growth of mold spores, and they will not be able to grow and create problems unless moisture is present. The key to controlling indoor mold growth is to control moisture.

What are some examples of ways I can control moisture?
Act quickly to correct water leaks or spills. In most cases, it takes 24-48 hours before mold begins to grow.
Vent your clothes dryer to the outside.
Use exhaust fans when showering, cooking, running the dishwasher, etc.
Increase air movement with fans.
Use air conditioners during humid weather.
Install proper exterior wall insulation.
Make sure the ground slopes away from the foundation of your house.
Clean and repair your roof gutters regularly.
Keep air conditioning drip pans clean and drain lines unobstructed.

Does mold make you sick?
Molds do have the potential to cause health problems, although most people have no reaction to molds. Molds can produce allergens, irritants, and in some cases potentially toxic substances called mycotoxins. Allergic reactions to mold are most common. Common symptoms may include sneezing, runny nose, wheezing, red eyes, or mild skin irritation. Like other types of allergies, different people will react differently to the same mold exposure. Certain groups of people who may be bothered more include infants or small children, elderly people, pregnant women, individuals with respiratory conditions or allergies and asthma, and people with weakened immune systems. Since the health effects of mold remain largely unproven, steps should be taken to remove mold and control any sources of moisture.

Gutter Problems Contribute to Mold Issues

In the May 11th article from Consumer Reports titled Home Repairs not to Ignore, there are several points regarding moisture and how it can lead to expensive problems with mold growth. "If there are 10 things that can go wrong with a house, 15 of them have to do with water, says Bill Loden, a Madison, Ala., home inspector." The article goes on to provide several useful tips for homeowners including:

• Gutters, downspouts, and leader pipes collect rainwater and channel it away from the house. In very wet regions, leaders should extend at least 5 feet from the house.
• Check the entire gutter system seasonally for proper pitch and for clogs, corrosion, broken fasteners, and separation between connections and where gutters meet the fascia board.
• When inspecting gutters, extend straight ladders 3 feet beyond the roof at a 75 degree angle to the ground.
• The soil around the foundation should slope away from the house at least 1 inch per foot for 6 feet or more.
• If you have planting beds along the foundation, make sure the grading of the bed, its edging, or the edge of the lawn isn't keeping water from draining away from the house.

Air Matters often sees gutter and landscaping issues such as these contributing to excess moisture in the crawlspace or basement of a home. Remember that in order to control the mold, you have to eliminate the moisture.
