Keeping Your Family Safe Program - Talks about IAQ And Mold Certifications

Monday, January 26, 2009, we had the pleasure of interviewing Mr. Charles Wiles, the executive director of the American Indoor Air Quality Council for our internet radio program “Keeping Your Family Safe” (find it at http://www.voiceamerica.com/ on the Green Talk Network). In our program, we discussed the certification in the indoor air quality and mold industry. We covered the following points:

  • Someone who is looking for a professional in the indoor air quality and mold industry should ensure the individual is licensed by federal, state, or local regulations. Since there are only a few states requiring licensing or certification (ie, MD, FL, TX), the individual you hire should have a voluntary certification.
  • If the individual voluntarily certifies, the individual’s certification should be an industry certification versus a curriculum-based certification.
  • An industry certification that meets the highest standards and qualifications must be issued by an industry organization that is accredited by the Council of Engineering and Scientific Specialty Boards, follow the International Standards Organization standard 17024, and is independent from the training providers.
  • The American Indoor Air Quality Council has a number of certifications that meet these requirements visit there website at http://www.iaqcouncil.org/

This Monday, February 2, 2009, we will be interviewing Mr. Chris D’Andrea, a Certified Industrial Hygienist who oversees the Office of Environmental Investigations with New York City Department of Health and Mental Hygiene, regarding revisions to the City’s current guidelines on mold assessment and remediation.

Keeping Your Family Safe Program - Talks about Mold Sampling


Monday, January 19, 2009, we had the pleasure of interviewing Dr. Harriet Burge, formerly from Harvard’s School of Public Health and the current Director of Aerobiology at Environmental Microbiology Laboratories for our internet radio program “Keeping Your Family Safe” (find it at http://www.voiceamerica.com/ on the Green Talk Network). In our program, we discussed the mold (microbial) sampling. We covered the following points:

  • General discussion on fungi and molds.
  • The most common health effect of molds is an allergic reaction.
  • Other health effects include infections and fungal sinusitis. Health effects of mycotoxins are controversial.
  • Fungi need water and food to grow. When fungi grow in places we do not want them we call them molds. Fungi and molds spread by spores.
  • Three types of sampling (bulk, surface, and air).
  • There are no standards.
  • Each method has advantages, but air is the only way to document exposure.
  • Viable (culturable) versus nonviable (particulate).
  • Culturable sampling are strongly biased.
  • Particulate sampling can be a very powerful tool.
  • There are new methods but not commonly used yet.
  • A number of samples are needed to get representative results and document exposure

This Monday, January 26, 2009, we will be interviewing Mr. Charles Wiles the executive director of the American Indoor Air Quality Council regarding certification in the indoor air quality and mold industry.

Senator Obama vs Senator McCain

With the Presidential election only days away, it is interesting to review what the candidates have said in regards to the environmental, occupational safety and health industry. The link above follows comments made by both candidates regarding Occupational Safety and Health Administration (OSHA). Below are highlights from Indoor Environment Connection's (http://www.ieconnections.com/) article regarding Indoor Air Quality "Obama and McCain - How Do They Differ on IAQ Issues?"

Senator Barack Obama has said he will conduct "a thorough overhaul" of the policies of the Environmental Protection Agency (EPA), and direct the Department of Housing and Urban Development (HUD) to increase resources to the problems of mold and radon abatement.

  • establish a program to educate building owners & homeowners on indoor air treatment and source abatement options.
  • a central part of Obama's proposed environmental policy is his promise to "create millions of new green jobs."
  • ensure 10% of our electricity comes from renewable sources by 2012, & 25% by 2025.
  • setting aggressive energy efficiency goal to reduce electricity demand 15% from projected levels by 2020.
  • a national commitment to weatherize at least one million low-income homes each year for the next decade.
  • implement an economy-wide cap-and-trade program to reduce grenhouse gas emissions 80% by 2050.
  • national health tracking system that would enable the government to determine links between environmental conditions and health problems.

Senator John McCain has been quoted as saying "air quality standards need to be more stringent."

  • McCain has focused on dealing with climate changes.
  • will use a portion of environmental credit auction proceeds to reduce impacts on low-income families.
  • will incorporate measures to mitigate any economic cost of meeting emission targets, including trading emission permits to find the lowest-cost source of emission reductions.
  • McCain envisions permitting America to lead in innovation, capture the market on low-carbon energy production and export to developing countries.
  • McCain's plan "will address the full range of issues: infrastructure, ecosystems, resource planning and emergency preparation."
  • In addition, McCain wnats to continue the "Clear Skies" initiative that was begun under President Bush, which concentrates on reducing mercury, sulfur dioxide and nitrogen oxides.

Senator Obama has said he supports the "Green" building construction bill while Senator McCain supports the principles behind the bill but is "not convinced that a new federal spending program is the best way to achieve this goal." The "Green" building construction bill would spend more than $20 billion over the next 5 years to help states build and renovate schools to make them more energy-efficient and environment-friendly, including efforts to improve the school's indoor air quality. The measure is intended to save school districts billions in energy costs while reducing asthma and other environmentally linked health problems.

On Tuesday, November 4, 2008 the United States of America goes to the polls to vote in one of the most historic presidential races of our times. It has been said a number of times already but this is easily the most important election we have had in a long time. So I would encourage all of you to go and vote. If you don't you will only have yourself to blame!

How many clearance samples should be taken for mold remediation?


In a recent article written by Dr. Harriet Burge, in The Environmental Reporter for EMLAB P&K, she discussed this question and came up with an interesting answer. As we discuss in our mold remediation classes, clearance sampling is used to document that the mold contamination was successfully removed as part of a well designed written protocol (scope of work).

In preparing the scope of work for the project, the consultant should take pre-abatement air samples to have a picture of the air before the remediation. Air samples should be taken inside the area being remediated, outside the area being remediated, and outside the building. This sampling must be representative of the air in the areas sampled. Using these results and the data created, the consultant (writing the remediation protocols) can pre-determine the percentage change they want to see in the clearance samples and add that information to the protocols.

Based on Dr. Burge's article she suggests that the number of air samples should represent 5% of the air in the room or 2% of the air in the room if the air is thoroughly mixed. (when mixing air the method used should not send so much dust in the air that it will require you to sample for less than 10 minutes). Assuming a 10 minute air-o-cell sample represents slightly more than five (5) cubic feet of air, a 1000 cubic foot room would require four (4) samples to achieve 2% with proper mixing and ten (10) samples without mixing.

It is important to remember no single sample is representative of any environment (as discussed in Dr.Burge's article and supported by various publications by the American Conference of Governmental Industrial Hygienists (ACGIH), the American Industrial Hygiene Association (AIHA), and others). As consultants, we must ensure the remediations we recommend are complete and this can only be accomplished if the interpetations are supported by quality data that is representative of the environment we are sampling. Multiple samples are the only way to ensure the environment is accurately evaluated.

Mold Evicts Occupants from their Westbury Apartments


On March 28, 2008, the Archstone Westbury Apartments deadline arrived for occupants to vacate their apartments. Archstone-Smith, a Colorado company, that manages the Archstone Westbury Apartments terminated the leases of these tenants on Wednesday, November 28, 2007 because mold and mildew had infested the apartments. In order to determine the cause of the infestation, the owner needed to open walls and ceilings to determine the underlying cause of the water intrusion.
It was good to see an owner being proactive in trying to prevent tenants from being exposed to mold or mildew. There are other ways to perform this investigation, including the use of infrared cameras and moisture meters, though it is probably better to ensure the safety of the occupants while determining the underlying cause.
As in many mold problems, according to newspaper articles written at the time this site also had a long list of water intrusion problems that were not addressed by the building maintenance staff. We could only speculate that had the maintenance staff responded faster or performed a more thorough investigation or water clean-up that the current evictions could have been avoided. Building owners should look at there building maintenance programs and ensure that all complaints of water intrusions are handled within 24 hours. Any evidence of moisture intrusion should be thoroughly investigated to determine the cause (again the moisture meters and infrared cameras would be helpful) and the water intrusion should be dried completely utilizing water collection devices (mops & wet vacuums) and drying devices (fans & dehumidifiers). Once mold grows on the property it indicates a lack of attention by the apartment owners, building owners, occupants/tenants, and building maintenance staff. When dealing with mold the best offense is to determine the cause of the intrusion and the best defense is to dry everything within 24 hours. It is also important to remember the use of bleach is unnecessary. The Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) both recommend the use of detergents instead of bleach. Bleach is a very strong chemical (it is a biocide) and is not needed to clean areas properly.

Residential Mold Case Goes Against Residents



An interesting piece of information was printed in the New York Law Journal, dated October 18, 2006 regarding residential mold and a resident's ability to sue based on health problems suspected of being caused by the mold. According to the article, Manhattan Justice Shirley Werner Kornreich found that the plaintiffs (Colin and Pamela Fraser) failed to demonstrate that the community of allergists, immunologists, occupational and environmental health physicians accepted their theory - that mold and/or damp indoor environments cause illness.
This is the typical story regarding mold. The Frasers developed a variety of health problems while living in a moldy apartment on East 52nd Street. Justice Kornreich conducted a Frye hearing to assess the scientific viability of the claim. Both sides submitted reams of evidence, laboratory results, and 4 witnesses testified, 2 for the plaintiffs and 2 for the defense.
Though this is not likely the last case we will see, I think it will be interesting to see where this heads since the article also mentions the Netti v. Auburn Enlarged City School District which had an opposite ruling back in September, 2006.
