Abstract:
A four-step procedure was developed and implemented in a specific case to evaluate theeffectiveness of remediation for mold impaction and water incursion. In step one, objectivewater incursion tests were conducted at selected repair sites. In step two, samples ofreplacement materials were analyzed for compliance with a set of statistically basedevaluation criteria for clearance, before installation. In step three, after remediation butbefore occupancy, non-destructive samples from within previously defined grids for eachimpaction site, and air samples from indoors and outdoors were analyzed for compliance withthe evaluation criteria. In step four, after occupancy, repeated air samples were analyzed forcompliance with the criteria. To demonstrate the usefulness of this procedure, results for onecase were summarized. It was concluded from these results that the procedure is robust yetsensitive, and that assurance of compliance with valid and reliable evaluation criteria forclearance increases confidence in the remediation effectiveness in new and existing buildings.
