Full Description:
Radio Joe is on the road at the IAQA Annual Meeting and last week attended a Sloan Workshop: Roadmap Research to Practice. Radio Joe will be reporting on both events this week and we will debut our new format for the show. The Sloan workshop was put together by Richard Shaughnessy, PhD and Jordan Peccia, PhD. It was a fascinating meeting of about 15 practitioners, 15 researchers and a handful of government representatives from agencies such as EPA, HUD and CDC. It was designed to allow practitioners to let researchers know what we need from research to do a better job helping people live in better indoor environments. This workshop focused on the Microbiome of the Built Environment and included a lot of discussion on mold and water damage topics. Radio Joe will review the presentations by both researchers and practitioners to bring listeners up to speed on what was discussed. The IAQA Annual Meeting is always a highlight of the conference season. This year it was in Chicago and was in conjunction with the ASHRAE AHR Expo. As always there was a huge expo hall with thousands of exhibitors and some excellent presentations at the Hilton Chicago.
Z-Man’s Blog:
- EPA’s Indoor Environmental Group interested in reducing health effects and financial burdens of dampness and mold.
- #1 EPA inquiry for her group 20 years ago and still today is mold.
- The seven essentials of “Healthy Homes” Program is important
- Real Estate Assessment (Sec. 8) now working on a pilot program that incorporates moisture meters & IR imaging into inspections.
- CDC interest grew after the Dampness and Mold publication
- It increased more after Hurricane Katrina which also led them to look at chronic exposure.
- They have fairly recently published recommendations for clinicians
- One current focus is on infectious fungi.
- See or smell mold
- measured building moisture
- measured microorganisms
- a. Can the normal fungal ecology of a building be described for different geographies, climates, and for buildings surrounded by different land uses (e.g. urban vs. rural)? Does it need to be?
- b. Do we know the ecology of fungi growing on damp building materials well enough to determine if a building is impacted by fungal growth due to dampness? How do these fungi differ from fungi that are part of the natural ecology?
- c. Do practitioners even care? If so, what are the research/practitioner needs for fungal ecology?
- a. How can DNA-based tools be used to indicate a need for remediation or to notify if a building has been cleared? Meeting of standards?
- b. How can mVOC measurements be used to indicate the need for mold remediation or to indicate clearance? Meeting of standards?
- c. How can (and should) building sensors (RH, ERH, T, VOC sensors) be incorporated into inspection and restoration practice? What applied research is required to advance these tools?
- a. What applied research is needed to advance the prevention or remediation effectiveness of mold in buildings?
- b. What innovations are needed to reduce the cost of effective moisture/mold remediation?
- c. Do we need additional or improved guidelines or standards to guide inspection and indicate the success of remediation?
- Need to better understand the association between fungal species and water damaged buildings.
- Finland has guidelines based on cultures about what is normal in buildings
- Looking at water damage and fungi in different types of materials
- What is normal fungal ecology?
- D 7391 12 categories of mold required to be reported on spore trap sample results
- Common water damage indicators are globally distributed
- Comparisons used in the past include indoor/outdoor, Spearman Rank Correlation, Friedman Chi-square
- What is Condition 1, 2, 3 per IICRC S520 was discussed so researchers have a better idea of the type of standards practitioners commonly use.
- Finland doesn’t have as many visible mold issues as it seems we have in US. They mostly deal with hidden mold. There are more HRVs used in homes and homes commonly have neutral pressures.
- New tools for microbial assessment include the use of DNA methods such as qPCR, which has shown promise.
- Had a great quote comparing a Tolstoy quote and one his professor used goes similar to this:
- All happy families resemble each other but each unhappy family is unique Tolstoy
- All healthy homes resemble each other but each unhappy home is unique
- There is less Richness of fungi and bacteria found in properties after remediation.
- Standard air and dust sampling useless for exposure assessment
- They are also rarely helpful in assessment or after remediation
- There are 100,000 types of mites we only know about allergens from a dozen or so. Point brought out by a photo of a mite eating mold in a T. Brennan slide.
- qPCR methods have shown some promise in predicting health outcomes
- Practical thinking-find out what’s wet, has been wet, or gets wet?
- We need x-ray vision
- Field microscopy can be helpful in guiding investigations
- Focus on VOC’s and how to possibly use them for answering some of the questions we have.
- Could they help in finding hidden mold. Not yet but work continues.
- The built environment is a microbial wasteland.
- Discussed ongoing research looking at microbiome on surfaces of different materials such as MDF, OSB, Gypsum board, etc.
- Short discussion ensued about the duration of loss and Ralph Moon’s research
- 20-30 years ago I sampled everything
- Now he tells customers “this is your problem if you want me to prove it that will cost another $$$$”.
- We already have issues with the type and number of samples, what materials to sample? Do we know what the results mean? We will need those answers for the new techniques.
- He is doing some fascinating work with standardized protocols while working with NYC housing authority on dampness and mold problems.
We need:
- better inspections
- better understanding of the connections between health and environment
- better information on the HVAC fiberglass nightmare
- better methods for documenting inspections
- better ways of preventing re-occurrence
- How much PPE is really needed?
- What is normal?
- Must we clean to a “clean room” standard?
- Do plumbers, handyman, etc. really cause health issues?
- Is it better to fix the moisture and clean up as we do with other construction or are HEPA vacs, neg air etc. vital to properly completing these projects?
- Do we need new standards?
- Is there need for additional guidelines to improve on mold inspections, or to improve on successful mold remediation? Probably!
- What are the implications of residual surface contamination in specific environments.
- Discussed the metrics/markers for gauging surface contamination.
- Went over existing research on ATP applications.
- We hope to get Dr. Cole on a future show to follow up on this!
- Spoke about the practical aspects of cleaning metrics, including ATP.
- Fascinating presentation on bio-films we did not get to discuss on this show. We must get Dr. Whitely on the show. An Aussie that is doing work with cleaning products in highly sensitive populations (healthcare) worldwide.
- They like to tell inspection/remediation stories – homes are very different;
- Microbial analysis is a part (small) of the large array of tools used for inspection and remediation;
- We all clearly need to discuss spore traps;
- Nuance in following standards and post-remediation verification.
- Practitioners should to be involved in almost every building mold/moisture study.
- What fungi or bacteria grow on damp building materials?
- Normal fungal (bacterial) ecology is a primary concern/task?
- What VOCs (SVOC’s, IVOC’s) indicate mold/bacterial growth?
- What is the normal VOC (SVOC, IVOC) background?
- Sensors with high selectivity and low cost would be very useful….make those.
- There is a large suite of questions surrounding containment, personal protection, etc… that practitioners would like evidence based researcher guidance;
- Molecular methods are totally ok with practitioners…..but they need to work, they need to be cheap, and they need to be fast.
- The event was appropriately structured and presented. The gulf between research and practice transforms from an obstacle to an opportunity for both.
- Each side heard important information from the other that directly affects the work that they do.
- We all want to do a better job and that means we must be more comprehensive which means we need the points of view and the expertise from other disciplines.
- My hope is that the follow up and next steps will occur quickly so the momentum can continue and can spread.
