About this file
This document is an attachment containing dust wipe test results for an HVAC system located in Building C, 3rd Floor of the Government Publishing Office (GPO) facility. The test results show lead concentration levels found in dust samples collected from various HVAC components, including ducts and air handling units. The lead levels ranged from 450 μg/ft2 to 8,800 μg/ft2, indicating a potential need for HVAC duct cleaning.
The related federal contract opportunity is for HVAC Duct Cleaning Services on the 3rd Floor of Building C at the GPO facility. The solicitation number is 040ADV-24-R-0064, and the opportunity type is a solicitation. The description states that the HVAC system was constructed in the 1970s and has not been cleaned in over 50 years, leading to the accumulation of impurities, particularly lead, in the ductwork. The GPO is seeking to have the ductwork cleaned to ensure the air supplied to the office does not contain these impurities.
