This is a forum on the Science of Drying, Disinfection, Remediation as well as Health and Insurance. It is provided ad-free as a public service by John Downey with funding from NAERMC (Free-Mold-Training.org.)

No registration required to read the articles. Registration is necessary to join a discussion. We will not sell your information.


The site includes 5 specific discussion forums: Drying, Disinfection, Remediation, Health, and [Contractor] Insurance. We also include a discussion forum for articles referenced by CIRI, R&R and CleanFax.

When you search the DDRS forum, you search the entire site. On each article, you will notice a rating between 1 and 5 stars which we hope will help prioritize the reader's time.

Generously sponsored by the National Association of Environmentally Responsible Mold Contractors (NAERMC) in cooperation with Free-Mold-Training.org; the American Risk Management Resources Network (ARMR); and the Cleaning Industry Research Institute (CIRI). 

Further sponsorship opportunities available.


Each month we will host one or more rated articles related to Drying, Disinfection, and Remediation Science, as well as Health and Insurance. By leaving your thoughts in the comment section below each article, we can create informative conversations that move the science forward for all.

All articles, including older/archived articles, are open for discussion.
