Air Sampling for Mold Spores is NOT a Mold Inspection and NOT an Air Quality Sample
Mold has become an issue for homeowners and home buyers across the country.  Mold inspections have become a part of most real estate transactions.   However, here in Florida, a mold inspection has become a bit cliché even passé.  Today it’s all about Air Quality.  Why call it a mold sample if you can charge more and call it an Air Quality Sample?  I’ve given my 2 cents about the value of mold sampling and the total lack of value in simply sampling for mold and calling … (0 comments)

john lapotaire: What "IS" a Real Mold Inspection - 07/13/16 11:42 AM
What is a Mold Assessment?
I once again raise this question because I’ve been called in to provide yet another second opinion of a mold inspection that consisted of nothing more than the collection of a few air samples for mold spores.  I assure you that a correct mold assessment in accordance with the only industry standard of practice does not involve the random sampling of mold.  The only industry standard of practice is the ASTM D-7338 Assessment of Fungal Growth in Buildings.
The question of just what is a mold assessment is a frustrating and surprisingly hard question for many industry professionals … (1 comments)

john lapotaire: Should You Test for Mold? - 02/28/10 06:41 AM
When we get calls for mold testing, we conduct a very thorough client interview to help get us acquainted with the client and to help determine the client’s individual needs.  In some cases the client simply needs to have air samples collected to find out if there is a presence of a known allergen in their home or office.  In other cases they need to know why there is mold in their home or office and how to stop it from growing and how to get rid of what has already grown.
And far too often we are asked to … (0 comments)

john lapotaire: Bioaerosol Laboratory Result Interpretation - 02/26/10 08:47 AM
There are no government-issued numerical standards for mold interpretation. However, use the following arbitrary numbers for guidance in interpreting microbial survey results. Bioaerosol
<250 CFU/m3 Low/Normal (CFU/m3 = colony forming units/meter cubed) 250-1,000 CFU/m3 Moderate/Borderline >1,000 CFU/m3 Active Growth/Sporulation >5,000 CFU/m3 Very Active Growth/Sporulation Our final mold interpretation is not based solely on the spore count numbers. Information gathered from the visual inspection of the areas sampled is very significant, including sources of moisture or high humidity, areas of elevated particulate matter, and signs of visible mold growth.
In air samples, it is important to consider the type and … (0 comments)

john lapotaire: Formaldehyde Council recommends testing homes for formaldehyde - 08/25/09 02:50 AM
The Formaldehyde Council, Inc. (FCI) engaged an industrial hygienist to explain formaldehyde testing methods. Larry Newton, CIH, CSP, has performed over 400 indoor air quality investigations. Newton expressed concern that some modern homes do not bring in adequate fresh air. He agreed with our statement, "lack of fresh air allows chemical contaminants to concentrate inside the home". Newton explained how he tested homes for formaldehyde in the 1980s. When I began indoor investigations, I used a CEA 555 continuous environmental analyzer (CEA) based on the wet chemistry of pararosaniline. This chemistry is highly specific and sensitive (< 100 ppb) to formaldehyde...The … (0 comments)

Will it have a musty stale smell? Did they have pets or smoke?" And finally: "What will I have … (0 comments)
