PROJECT ARCHIVES: Arc Environmental, Inc. was contracted to conduct a microbial investigation of three areas in the Baltimore City Community College Bard Building, located at 600 East Lombard Street in Baltimore, Maryland. The assessment included an investigation of areas of concern in the building for possible microbial growth, tape lift sampling of visible mold growth, and spore trap air sampling of the building. The visual assessment, air sampling, and tape lift sampling indicated mold growth on the suspended ceiling tiles and grid, gypsum board walls, upholstered furniture, carpet, and books throughout the three areas assessed. The preliminary assessment indicated that high levels of humidity in the air dispersed by the HVAC system and a history of building envelope failures contributed to mold growth.
Arc Environmental performed visual and air clearance sampling for each phase of the abatement and concluded that the post remediation sampling criteria had been met. Post-remediation humidity monitoring was conducted on the second and third floors to assess whether high humidity levels had been corrected. The assessment took place over a period of eight weeks. After repairs of the HVAC systems were completed, relative humidity re-asessed and was found to be within ASHRAE guidelines. |

A follow-up investigation was conducted on the fourth and fifth floors of the building to ensure that microbial contamination had not spread from floor to floor. Air and tape lift samples indicated these areas were not affected by microbial contamination.
