Mold Tests

Mold tests alone for homes in Naples, Marco Island, , Cape Coral or anywhere in Florida should not be used to determine if a structure needs mold remediation.

A thorough visual inspection, including infrared thermal imaging cameras and moisture meters is the most important part of any mold assessment. Mold Inspection should include source identification, extent of mold growth with documentation and recomendations for corrections based on accepted industry standards such as the S520 and S500

"Should You Trust a Laboratory to Interpret Your Mold Results?

Indoor air quality as a scientific discipline is evolving as our knowledge of the subject increases. We know that sample results for fungi and fungal spores are highly variable even under the most controlled sampling conditions. Given the complexity of interpreting your results, can you really rely on a lab doing this for you?


Here are some reasons not to:
1.
Laboratory results by themselves should not be used alone to form the basis of your data interpretation. Visual inspection of the site, site location and nearby land use, understanding the site history, identifying indoor micro-climates, and interviews with affected occupants should play a major role in your result interpretation.


2.Fungal counts have spatial, geographic, local land use, seasonal and diurnal variability just to name a few. This variability can be orders of magnitude different in samples that are taken a few minutes apart! An interpretation of your samples that is based on subjective, un-validated internal criteria developed by a laboratory is a great way to make incorrect conclusions!


3.
We know that different sampling devices result in different collection efficiencies that depend on the spore size. This variation is significant when comparing sampling devices. These collection efficiency differences are not taken into account by labs offering this type of data interpretation! What are you really getting? The sole purpose of a laboratory is to provide you with independent, objective, and scientifically defensible data.

Labs that offer you statistical data interpretation, a score, or tell you whether your samples have elevated mold levels are jeopardizing your reputation and exposing you to professional liability. No one can afford that kind of service. "

         Considering Bioaerosol Sampling

 

 

"remember that a negative sampling report must not be used in place of a visual survey. Factors such as barometric pressure, inside and outside temperatures, activity levels, and humidity may dramatically reduce or increase the spore levels within a building. Air sampling for mold provides information on what was in the air only for the moment when the sampling occurred. It is important, therefore, that sampling not replace visual inspection."

Can your home inspector interpret your lab results?
 

 

 

"Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, sampling methods, and interpreting the results."   EPA

 

"Experience in interpretation of results is essential.”   EPA

American Conference of Governmental Industrial Hygienists (ACGIH)

ACGIH Bioaerosols: Assessment and Remediation states [section 1.2.3]:
Some organisms and sources release aerosols as 'concentration bursts' which may only rarely be detected by limited grab sampling and may be masked in measurements of long-term average concentrations. Nevertheless, such episodic bioaerosol releases may produce significant health effects. -- thanks to S. Flappan for suggesting this citation.

"Spores are not always airborne during sampling: Mold spores may not be in interior air at the time of the sample but may be present in high levels at other times."

 

The book "Fungal Contamination" is considered one of the best mold inspection resources documents in the country by professional mold assessors.

"A Manual For Investigation, Remediation And Control"

  • "Anything can be toxic in high enough concentrations, even water!  If you drink too much water to quickly, your body fluids will become dilute.  The result is tissue damage and death."

 

  • "The overall visual observations made of the building must be considered in combination with the results of any testing, to determine the overall condition of the building. Test results alone should never be considered to give a definitive account of the building's condition."

 

  • "Testing is just another tool that provides us with information. By itself, testing does not do anything, accomplish anything, or fix anything." 
 
 
  •  "Indoor levels of fungal spores may also be elevated as a result of poor interior hygiene and housekeeping.    This by itself, or in conjunction with inadequate air movement and filtration, can easily result in elevated levels of spores both in the dust on surfaces (transitory) and in the air." 
 
 
  •  "No single type of testing or piece of information should be used to determine the condition of the building; findings made as a result of observations should never be discounted in favor of measurements."

"Sampling results are of limited value because mold concentrations inside and outside vary considerably, methods of collection and analysis are not standardized and no widely accepted exposure guidelines exist."

http://www.inspect-ny.com/sickhouse/OutdoorMoldCounts.htm

"warm weather spore counts vary during the day as weather conditions (humidity, temperature, period after rainfall) affect sporulation and spore movement.

American Conference of Governmental Industrial Hygienists (ACGIH)

Section 2.4.2.2 of The ACGIH Bioaerosols: Assessment and Remediation offers:
Investigators should bear in mind that samples provide information about a site as it existed at the time tested. However, the findings may not represent conditions at a time in the past or future, even the relatively recent past or near future. Changes in the kinds, concentrations, and proportions of biological agents in the air can be rapid and substantial. -- thanks to S. Flappan for suggesting this citation.

"OPINION: There are severe problems in the standard practice comparing indoor and outdoor spore counts to decide if a building has a mold problem."

http://www.inspect-ny.com/sickhouse/MoldTestNegatives.htm

Individual samples of particles in air show tremendous variation from minute to minute, making "ok" airborne mold spore test results a thing to view with skepticism. Examples of factors which can cause an exponential difference in particle levels in indoor residential air over short time intervals include: mechanical disturbance (walking across a carpet or moving a moldy cardboard box), operation of hot air heating system or central air conditioning system, operation of other building fans, particularly ceiling fans and vacuum cleaners, turning lights on and off, and opening or closing windows and doors

"Risk of false negative mold tests: Experienced mold contamination investigators should have little confidence that a one-time low or "ok" "toxic mold test spore count" is an assurance that problematic particles are not present."

MoldReport™

http://www.moldreport.com/mold_faq.html

 

"A professional mold inspector does not rely only on air sampling results to decide whether or not a home has a mold problem. Carefully conducted sampling is combined with visual inspections and discussions with the homeowner. In addition, many different factors affect the reliability of an air sampler. The professional mold inspector understands these variables and accounts for them in the sampling plan."

  University of Minnesota fungal experts

http://www.inspect-ny.com/sickhouse/OutdoorMoldCounts.htm

 

"The University of Minnesota fungal experts observe that an outdoor-baseline comparison to indoor air is not valid when the outdoor sample was taken during or immediately after precipitation (spore counts plummet outdoors in the rain and might soar right after it),"

2.1 Visual Inspection

"A visual inspection is the most important initial step in identifying a possible contamination problem."

  Martin Yerfino, CIE

Many Mold inspection companies only perform "Mold Testing". Mold testing should not be confused with a Mold Inspection. Mold testing refers to collecting air or surface samples which are analyzed by a laboratory, this procedure will only determine the  mold spore count and spore identification. This process will not help determine what caused the problem, the source or the solution to it; but is very helpful when performed in conjunction with a full inspection.

A mold inspection report should at least include:

·   Air and or surface sampling
·   Findings of visual assessment
·   Boroscope inspection
·   Air Conditioning test and inspection
·   Identification of water intrusion sources
·   Relative Humidity and condensation readings
·   infrared thermal imaging inspection
·   Particle counts
·   Building pressure test
·   Moisture detection
·   Prevention and correction Recommendations

 
Most Common Mistake For Outdoor Air Sample Collection.

Outdoor or base line air sample must be collected at least 10 feet from the structure according to the Indoor Environmental Standards Organization (IESO).    This is the only standard for mold testing approved by the American National Standards Institute.

Environmental Solutions Association (ESA) requires outdoor air sample to be taken at least 5 feet from the structure. (good stanard but not approved by ANSI)

Common example of not following accepted industry standards:

Many Home / Mold Inspectors collect outdoor air samples on the lanai or balcony (not to standard).  This can possibly cross contaminate the outdoor sample, resulting in a false spore count.

"Is there any way to teach home inspectors enough about mold that they don't scare homebuyers with false alarms"

 

"As more than one person suggested, a home inspector can be compared to

a general practitioner (GP), while calling in the mold inspector is like visiting a specialist. The GP may be able to get a sense that something is wrong with the patient, but it's up the specialist to perform tests to discover the real problem and its significance. The goal is to keep the GP from sending the

patient running away in fear before the specialist can determine that those

headaches are really a result of minor dehydration, not of a massive tumor.

It's been said that a little bit of knowledge can be dangerous."

 
The Home Inspector mold "problem" is expected to disappear when the Florida Mold law becomes effective.  Texas passed a similar law a few years ago and eliminated the home inspector from mold assessment.
 
____________________________________________________________

Cultures are a bad idea when used to determine if home has mold problem

More info click here

http://www.inspect-ny.com/sickhouse/cultures.htm

"As an example, a dead spore in the air may be toxic but may not grow at all in a culture medium."

 

"Use of cultures as building screens for the presence or absence problematic mold is unreliable - only 10% of all molds of any genera will grow on any culture under any circumstances, so a mold culture screening test for mold is 90% wrong at the outset. More so if one considers that certain molds that can be grown in culture only respond to specific culture media."
