ATLANTA — Judging by the numbers and types of indoor air quality (IAQ) related bills passed during this year's state legislative sessions, indoor mold still reigns as the IAQ issue of most concern to U.S. state legislators, in particular regulating the licensing of people involved in mold assessment and remediation, according to Aerias, an online resource for IAQ information and education.
With respect to indoor mold, eight states have passed legislation with four of the 10 bills addressing licensing of mold assessors and remediators. Efforts have been made to exempt certified industrial hygienists from mold remediation license requirements, which so far have not been successful. Texas passed three of the indoor mold-related bills.
