Indoor Environments  2023 –
Radon and Vapor Intrusion Symposium
Proposals and Abstracts Due May 31

The Call for Proposals and Abstracts for the Indoor Environments™ 2023 – Radon and Vapor Intrusion Symposium  (formerly AARST International Radon and Vapor Intrusion Symposium). The 37th annual symposium will occur in Nashville,  October 29 – November 1, 2023.  MORE


AARST is rebranding to Indoor Environments Association™ to formally adopt work already started on chemical vapor intrusion and pursue efforts focused on other contaminants of concern in the built environment while maintaining significant attention to radon, the second leading cause of lung cancer. Attendant to that decision, the symposium is being rebranded this year as Indoor Environments 2023™ – The Radon and Vapor Intrusion Symposium. Over the next 12 months, the association’s website, logo, and public identity will change to align with the organization’s recently revised mission statement. READ THE PRESS RELEASE

Opportunity to Comment:  HUD Policy

HUD has released a draft new department-wide radon testing policy that recommends radon testing and does not require adherence to consensus standards or performance of initial measurement or mitigation by a qualified radon professional.

The decade of experience with multifamily lending program radon policy is the model for public policy addressing the dangers of radon. Public housing residents, home buyers, beneficiaries of block grant programs, and others reached by HUD’s other programs deserve the same protection from radon that is offered by HUD’s multifamily loan programs.

AARST encourages members to submit a comment to HUD by Friday April 14, 2023 through the online docket. View AARST’s draft comment.

HUD Asked, AARST Answers

Q: What guidance would a HUD grantee … need to successfully identify and mitigate radon?
A:  HUD grantees should ensure the use of “current techniques by qualified professionals” as required by 24 CFR 58.5(i)(2)(iv). Contracting with one of the thousands of radon professionals already credentialed by an EPA-recognized proficiency program such as NRPP and by the state regulatory agency as applicable, all of which require adherence to legitimate consensus standards, is one option. Another option is to build in-house capacity by getting staff properly trained and credentialed by an EPA-recognized proficiency program and state regulator as applicable. HUD grantees should not take the public health risk and incur the potential legal liability of having unqualified persons using substandard methods to identify or mitigate radon.

Attention: States, Tribes & Territories 

There will be a concurrent track at the AARST Symposium from October 29th – November 1st, 2023 for states, tribes and territories. This replaces the event formerly known as CRCPD National Training Meeting.

Those who wish to present should refer to the Symposium guidelines. The deadline for submission is May 31.

EPA Credentialing – Comments Needed

EPA announced its Proposed Radon Credentialing Criteria to help align and ensure consistency across credentialing programs operated by certification programs (such as NRPP) and states, based on standards, organizational and program-specific competencies, and third-party accreditation to ISO 17024. To be implemented over three years, the proposed framework could harmonize practices and policies and expand consumer trust and confidence in the radon service provider industry.
There will be a briefing Wednesday, April 12 at 1 PM ET – register HERE.
Comments are being accepted through May 22.

Request from NRPP:
Certification Surveys

Survey Responses Needed NRPP is still surveying individuals who completed multifamily measurement and mitigation courses about the skills and experience necessary for NRPP’s new commercial certifications (which will cover multifamily, school, mixed-use, and large buildings).
NRPP needs more participants’ info to keep the process moving forward. If you received the survey request in mid-January, please complete the survey. PLEASE email certification@nrpp.info if you can’t find the original email request and we will send the link.
