AirQuest was contracted to manage and supervise the demolition of an existing small arms firing range and excavation and disposal of lead contaminated soil. AirQuest developed a Worker Protection and Exposure Monitoring Plan (for OSHA compliance), Ambient Air Monitoring Plan (for CAA compliance) and Confirmatory Sampling and Analysis Plan (for RCRA and TSCA compliance) prior to site activities. The demolition debris was sampled to determine if it was a characteristic hazardous waste. Initial and periodic personal air monitoring was conducted during remediation activities to assist in the evaluation of exposure levels and the selection of appropriate respiratory protection. Background samples were placed in the vicinity of excavation activities to evaluate the potential exposure to intermittent site visitors. Daily air monitoring was conducted for lead to evaluate if the remediation activities were within the EPA’s National Ambient Air Quality Standards of 0.15 µg/m3. Each soil pile was sampled for disposal purposes. The site was gridded and elevations were recorded prior to collection of confirmation soil samples to confirm that all lead impacted soils were removed from the site. The excavated soils were treated onsite with EnviroBlend to render them as non-hazardous waste. The project was conducted in close coordination with the USACE and under direction from command at Patrick Air Force Base. Particular concern was placed on preventing exposures to base personnel, data validation, and the expeditious completion of the excavation and restorations.Industrial Hygiene | Solomans, MD
AirQuest was contracted by the Department of the Navy (NAVAIR) to provide semi-annual industrial hygiene evaluations of employee exposures to cadmium during work activities while refurbishing naval equipment. The work activities included: blasting in an independent metal containment; use of blast cabinets; use of a painting booth; and welding a variety of metals.
Prior to, during lunch and after sampling, the personnel pumps were calibrated with a BIOS primary calibrator. The samples were collected by drawing air into a cassette and forwarded to EMSL Analytical Laboratories, an American Industrial Hygiene Association (AIHA) accredited industry hygiene laboratory, for analysis of cadmium by NIOSH 7300M Method.Indoor Air Quality | USACE Buffalo
AirQuest performed indoor air quality sampling within several buildings located within the United States Army Corp of Engineers (USACE) Reservation Buffalo District. The investigation was requested by USACE in response to the USACE Command scope of work for indoor air quality sampling activities at the site. Placement of the testing devices and locations for direct reading instruments was done with input from the USACE LRB Safety Office staff. The scope of the investigation included the following in select areas of the buildings: collection of readings for temperature, relative humidity, carbon monoxide, carbon dioxide, ozone and ultrafine particulate levels using direct read instruments; 24-hour data logging of: temperature, relative humidity, carbon monoxide, and carbon dioxide; air sampling to identify airborne fungal particulate (non-viable) using spore traps; radon sampling and laboratory analysis; and Volatile Organic Compounds (VOCs) sampling and laboratory analysis by EPA Method TO-15.Hazardous Materials | Midway Atoll
AirQuest was subcontracted by Cross Environmental Services, Inc. to provide professional consulting services for the characterization, transportation and disposal of asbestos, lead contaminated and hazardous materials on Midway Atoll for the US Fish & Wildlife Service. Midway is approximately in the middle of the Pacific, and over 1,200 miles from inhabited land. The project constraints included limited access to the island (there is one flight in and out per week), the logistics of characterizing and transporting hazardous materials overseas and in several states (Hawaii, Oregon and Washington), and working with limited resources (only two (2) crew could be mobilized during the assessment phase and four (4) crew could be mobilized to the island during the transport phase). Asbestos and lead contaminated waste was consolidated, labeled and packaged. Samples of hazardous waste were collected and disposal profiles generated. All of the material was packaged and transported off of the island for disposal.
