- Conclusions and Recommendations
The sampling results of this demonstration indicate that the dry-fog tech- nology was capable of rapidly eliminating mold spores. Results also showed that the second step of the dry-fog technology’s (application of EVERpure) continued to reduce mold spore levels over time; with minor exceptions, while total spore counts outdoors increased throughout the demonstration, indoor levels continued to decrease. However, the in- creased values for hyphal fragments at Locations #3 and #4 in Bldg. 2261 during the 6-month sampling event did not conclusively confirm the tech- nology’s treatment effectiveness beyond 6 months.
This work concluded that the dry-fog technology provides rapid and quan- tifiable improvements to indoor air quality, and also that it drastically re- duces exposure of Army building occupants and maintenance workers to harmful chemicals resulting from current mold remediation practices.
Current rough estimates for application of the dry-fog technology are ap- proximately $1.00/sq ft. Actual costs would deviate from this estimate de- pendent on location and proximity to the vendor. It is likely that an installa- tion could achieve additional cost savings by acquiring an in-house capabil- ity to apply the treatment. Implementing the dry-fog technology at Army in- stallations would be relatively straightforward. The equipment could be pur- chased and the vendor engaged to train personnel in its use. Ongoing in- house training could be planned to disseminate additional treatment sys- tems across Army installations. Treatment systems could be purchased for use at each installation, or for use on a regional basis to share the technol- ogy across installations in neighboring geographic locations.
It is recommended that additional demonstration(s) be completed for longer periods (12 to 24 months). Ideally the demonstration(s) would be conducted in buildings where the indoor environment and building usage would remain constant throughout the demonstration period. It is also recommended that the dry-fog technology be demonstrated at new con- struction sites where it could potentially serve as a preventive measure.
