About this file
This document appears to be a test report for lead air results at the U.S. Government Publishing Office (GPO) Building C, 3rd floor. The air sample collected from the HVAC/duct system on the 3rd floor was tested and found to contain 949.2 micrograms of lead. The GPO is seeking to contract for HVAC duct cleaning services for the 3rd floor of Building C, as records indicate the ducts have not been cleaned in over 50 years. This is due to concerns that the air supply may contain impurities, with lead being the most concerning. The solicitation number is 040ADV-24-R-0064, and the opportunity type is a solicitation for HVAC duct cleaning services.
