12:05:05 From Ralph Froehlich : Fear of Friday the 13th
12:05:48 From cliff zlotnik : correct ralph, please send me ypur contact info czlotnik@cs.com
12:15:59 From Ralph Froehlich : It’s great that there two outdoor samples since it is difficult to calculate an average from a single outdoor sample. However, multiple indoor samples would be needed to compare indoor and outdoor mean concentrations.
12:20:25 From John Lapotaire : What caused the wet slab
12:25:46 From joe : Dr Spurgeon do you have an opinion where it appears over the years that NIOSH 0800 has been misused to the point that the way sampling is conducted by most "mold inspectors" i.e. one sample outside , one in a complaint area and one noncompliant and ignoring the consecutive samples. Also how this was applied to spore traps , when spore traps are not in the method description.
12:30:21 From Ed Light : Your critique of mold assessments is to be commended, Joe. However, your underlying assumption that better sampling strategies and data interpretation can be used to make recommendations are not supported by the scientific evidence. Therefore, making any findings drawn from mold testing test data should be considered inconclusive. My conclusions with respect to contamination are based on the public health standard- mold growth and excess dampness are not acceptable and must be resolved. Any conclusions on health should be based on relative exposure to mold and dampness as considered by a physician following generally accepted medical opinion.
12:39:58 From Ralph Froehlich : ERMI was developed to assess carpet dust, but not other surfaces. Accordingly, ERMI results should not be applied to the evaluation of other surfaces WITHOUT EXTENSIVE ADDITIONAL INFORMATION.
12:40:15 From Ben Kunze : Does anyone use the OFFA collection procedure with Allergenco-D cassettes? I'm interested in what you define as the surface area of the cassette--do you use the inner, capsule-shaped wall sampling shrouds area, or the diameter of the entire cassette?
12:42:01 From Ed Light : p.s. Scientists are generally not needed to assess and clear mold issues. A thorough visual inspection by an informed restoration contractor (which may need to include accessing behind enclosures and/or a comprehensive moisture assessment by an engineer, in complex cases) is generally sufficient.

Show Number: 737 Draft Blog

Joe Spurgeon, PhD
Write a Mold Assessment Report Not a Data Report

Good Day and welcome to IAQ Radio+ episode 737 Blog. This week we welcomed Dr. Joe Spurgeon to demonstrate how to write legally defensible mold reports.

If you ever write a mold report and it goes to court Dr. Joe Spurgeon could well be the expertonmold.com that reviews your report. Dr. Joe has retired his CIH and does not get out in the field much these days, but he still reviews reports and testifies in mold related case s on a regular basis. This week he has volunteered to tell us what makes a quality report and how to write a mold assessment report and not a data report. If you don’t know the difference this is the show for you. In addition to the presentation he put together for us this week Dr. Spurgeon has put up a special free link https://expertonmold.com/product/iaq-ra ... -download/ with his IAQ Radio presentation plus 38 new slides, copies of field sheets, "Notes on Writing a Mold Report", an example mold report and a mold site inspection list. You can also order any of Dr. Spurgeon's books from his website expertonmold.com.

Another great show for continuing education credits learn more here https://www.iaqradio.com/ce-credits/

His career has included working as a research chemist on the NBS Lead-Paint Poisoning Program, directing the FAA’s Combustion Toxicology Laboratory, performing Health Assessments for CDC/ATSDR, implementing US EPA’s Laboratory Exposure Assessment Project, and working as a consultant specializing in microbial indoor air quality for US PHS. He has performed numerous residential and commercial investigations involving water intrusions and microbial contaminants; has taught courses on mold investigations, sampling, and data interpretation methods; and has served as an expert witness in numerous mold cases. His books are available at http://expertonmold.com/

Nuggets mined from today’s episode:


Let’s start with your work as an expert witness. You commonly review mold reports, are they getting any better? No, they are getting worse.

What is an objective of your Presentation today? Show some new ways of thinking about – Mold Inspections – Mold Sampling – Mold Reports

How do you define an expert? It’s less about education, it’s more about someone who knows what their options are and how and when to use them.

What is a quality mold report? A quality mold report is the only evidence of the quality of the site inspection.

What is the purpose of the mold inspection?
Determine either Building Related Contamination or Occupant Exposure Potential.
• We are not looking for indoor mold, we are looking for excessive concentrations of indoor mold.
• We need either implicit or explicit criteria for detecting excessive concentrations of indoor mold
Defining a quality report?
• The report is the only evidence available to judge the quality of the inspection.
• How can we define a quality report? “You know it when you see it”
• A quality report is based on a reliable inspection that sufficiently characterizes the indoor environment – Can be difficult to judge by simply reading the report
• Need a more objective definition of a quality report
What Makes It a Quality Report? Basis: Federal Rule of Evidence 702 Criteria for Qualifying as an Expert Witness
1. Report demonstrates the inspector’s scientific and technical knowledge and their ability to understand the collected evidence. 2. Opinions, conclusions, and recommendations are the product of reliable principles and methods. 3. Inspector has reliably applied those principles and methods to support conclusions and recommendations. 4. The report is based on sufficient facts or data to support those opinions, conclusions, and recommendations.


Sufficient Facts or Data
• The basic elements of a mold inspection were not included in the project report – A visual inspection – But no site characterization, occupant interview, incident history
• Inadequate documentation of the inspection, conditions, sampling methods, sample collection, and conclusions – No use of Field Sheets
• Conclusions and recommendations were not associated with specific findings and results – No use of Data Tables in the body of the report
• Unsupported opinions, conclusions, and recommendations

Do you commonly cite industry standards in your reports? No, because no one complies with everything in an industry standard. When an industry standard is cited in an expert’s report the expert opens himself up to agreeing with and being queried about everything in the standard.

Reliable Application of Principles and Methods
• Inspector did not understand their sampling options or when and how to apply those methods – Total airborne spores when assessing Occupant Exposures
• Inspector assessed and discussed raw spore counts rather than standardized spores/m³
• The inspection was not sufficiently complete to determine the significance of the results – Two outdoor airs and one indoor air, who is teaching this nonsense?

What is the sampling Rationale? The: Where? Why? How?

No statement of project objective/s – Building-Related Contamination? Occupant Exposures? – Objective needed for rational assessment of the results
• Most residential reports are data, not assessment reports – Simply report the data
• No assessment (significance) of the sample results – Only “Interpretation” of results was by the mold lab
• A problem? Inspector referenced guidance documents (AIHA, ACGIH, IICRC) in the report – Then contradicted those guidance documents during the inspection
• Recommendations that occupants vacate based upon building related contamination not specific situations of occupant exposure.

Why was the carpet dust sampled?
To Assess Building-Related Contamination – Objective: Clean vs Discard • Total Fungi • Assess Occupant Exposure Potential – Basis: Occupant Interview • [Reported health effects.]

• More Recommendations to improve your reports: reports:
• Use Field Sheets to convert data into useful information understandable to clients and MIPs.
• Transfer sample data to Data Tables and then Interpret. Demonstrates patterns and concentration gradients in the data.
• Consider using composite samples when encountering budgetary constraints.
• Is the data consistent with observed results?
• Limitation of sampling: We can ID contaminated air, we cannot ID uncontaminated air.
