SIX Times the U.S. EPA told the Public do NOT use ERMI

DECIDE FOR YOURSELF

INTRO

In the very early 2000’s, a couple very good researchers at the U.S. EPA, developed the ERMI sampling and analysis method. They are considered the “inventors” of ERMI and were granted a patent for their technological achievement. Papers were published, and many scientists, specialists, and experts in the health and environmental sciences reviewed, commented and critiqued the method. Most of them were not complimentary or supportive.

Over time, the EPA realized it had to conduct an internal review of their own work, and the use of this novel analysis method. The result published in 2013 was astounding but also satisfying to those who fully understood the application, its shortcomings, and its misuse in the public for-profit sector.

“Consequently, homeowners and building owners are at risk of spending tens of thousands of dollars to remediate their homes or buildings based on test results that may or may not be accurate. Further, other homeowners and building owners may not take needed remedial actions to address indoor mold risks based on the test results.” - EPA

From 2013 until just recently in 2023, The EPA has warned the public in writing (and on webpages) at least SIX TIMES that ERMI is NOT valid for use as an assessment tool for building damage, mold growth, impact on health, or exposure.

There have been no updates and no new information, studies, validating research, or data that suggest this warning has changed, lessened, or been removed since 2023.

Any and all supporting commentary and criticisms about ERMI, PCR, and HERTSMI-2 are available elsewhere and all remain applicable and in full force at the time of this writing, April, 2024.

Short and to-the-point Origin Story of ERMI

• 2002 EPA - Patent for ERMI development

• 2004 EPA - ERMI research and development, related paper published.

• 2007 HUD and EPA. - First paper explaining ERMI development.

• 2007 – 2013: Endless criticisms and warning from the OEHS and Public Health industries.

“The EPA readily acknowledged that it had not validated or peer reviewed ERMI for public use. The agency said it considers ERMI to be a research tool not intended for public use.” - EPA
