TAGA: EPA's Mobile Sampling and Analysis System

TAGA Bus

EPA can deploy specialized equipment, including the Trace Atmospheric Gas
Analyzer (TAGA) bus, to the impacted areas in the event of a hurricane.

Leveraging mobile assets on scene reduces reaction times onsite and increases
the speed in which decision-makers get usable data.

How it Works	E*	1

The TAGA bus is a self-contained mobile laboratory capable of real-time
ambient air monitoring, as well as sampling and analysis of outdoor air

emissions It includes equipment which provides monitoring for many organic and inorganic compounds at the part-per-
billion by volume (ppbv) levels or lower; the mobile lab can also analyze volatile organic compounds at the ppbv level or
lower in air samples.

The system includes equipment to analyze permanent gases at part-per-million by volume (ppmv) levels; a global
positioning system (GPS), which supplies accurate, real-time positional data during mobile monitoring; and a GIS system,
which maps and presents the TAGA's position in real time.

Additional instrumentation - including, but not limited to, a mercury analyzer and electrochemical sensors for gases -
has been incorporated for specific programs This versatile mobile monitoring system offers a wide variety of services to
assist with cost-effectively conducting investigatory and enforcement activities.

The TAGA mobile laboratory has supported the Agency on numerous and varied responses, projects, developments,
preparedness activities, and deployments, including the Deepwater Horizon oil spill and World Trade Center emergency
response.
