Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

Equipment EPA Uses to Collect On-site Air Monitoring Data

During emergencies, EPA may use these vehicles to monitor and sample for substances that may be present in the environment. Use of these vehicles is based on the emergency and on decisions by the response team.

ASPECT: EPA's Airborne Data Collection System

The Airborne Spectral Photometric Environmental Collection Technology, or ASPECT, is a small aircraft EPA uses to detect and gather chemical and radiological data to assist response agencies in the US. ASPECT uses a variety of sensors and cameras that can quickly collect data and information and provide it to emergency response teams. Read more about ASPECT.

TAGA: EPA's Mobile Sampling and Analysis System

In response to a disaster, EPA uses a self-contained mobile laboratory to monitor air quality. The lab bus, the Trace Atmospheric Gas Analyzer, or TAGA, is capable of real-time sampling and analysis. It can detect chemicals at very low levels. TAGA also has specialized sampling equipment to use at remote locations and to measure air quality. TAGA aids EPA's efforts to rapidly identify and address potential environmental threats in disaster areas. Read about other EPA response equipment.
