The basement plaster ceiling and a section of the 1st floor were removed to fix the leak. Mold remediation was then completed and final visual inspection and Air-O-Cell mold spore sampling (mold clearance) was performed to confirm project completion.
Intermittent Sewer Gas Odor (Large Commercial Office Facility)
IAQ investigation into reported intermittent foul odor in an isolated cubicle area of this former office/printing facility which had been converted into an office-only building complex with multiple tenants. HVAC design incorporated a common air return plenum for each of the tenant spaces. No specific time correlation was established for the occurrence. Inspection identified several small capacity waste lift stations associated with kitchenette facilities and discovered one vent line, which was open within a wall cavity space and did not extend through the roofing system. The odor occurred as a result of line pressurization during the intermittent operation of the lift station forcing the accumulated sewer gas out of the piping system. As a result the odor migrated into the occupied space. Once identified, the line was extended through the roof venting odors outdoors and completing the project.
Sewer Gas - Banking Facility Basement
IAQ investigation identified an improper tie-in from the basement bathrooms to a sub-floor sewer line. AET was able to delineate the location of the problem and the line was reconfigured/sealed thus eliminating the odor and eliminating employee complaints.
Natural Gas from Hot Water Heater (Early Morning Hours Only)
Numerous visits by the local fire department failed to identify the source of natural gas odors in a Landover, MD Bank Facility during morning opening hours. AET utilized a Gas-Trac NGX-5 meter to identify a leak in the by-pass switch for the pilot light in the hot water heater. AET determined that the facility HVAC unit was on set-back mode (i.e., minimal operation) during off hours. The gas leak on the water heater allowed vapor build up in the mechanical room resulting in a concentration gradient which was entrained in the unit during initiation of normal operation mode (i.e., approximately 0830 daily). During the course of normal operations, the gas level was reduced due via dilution ventilation.
