ABSTRACT

AECOM has been designing, installing and operating perimeter/fenceline ambient air quality and meteorological programs for over 30 years. AECOM’s more recent experience includes many monitoring programs around hazardous waste sites, landfill excavation projects plus former Manufactured Gas Plant (MGP) and Hex Chrome (Cr6) site remediation projects. Over the years, we have designed, implemented and operated many different types of perimeter Air Monitoring (AM) programs. The AM programs typically ranged from the very conservative to the much less conservative design and styles. This presentation will focus on and present information and comparisons concerning the various approaches AECOM has encountered in the design and operation of site remediation perimeter monitoring programs. All of the various AM system design and operational approaches to be discussed will be programs designed and operated by AECOM under the scrutiny of the various regulatory bodies overseeing the site-specific remediation activities.

The presentation will focus on the various design specification and operational protocol comparisons, with an assessment of the various advantages and disadvantages of each perimeter monitoring approach including the following design and operational comparisons:

• Monitoring and data quality objectives
• Parameters measured
• Parameter-specific action levels
• Instrumentation
• Data telemetry/ Action Level Alarms
• Frequency of sampling/ Length of Monitoring Programs
• Number and placement of monitoring locations
• Cost of Perimeter Monitoring Program.
