ERT is EPA’s premier air sampling and air monitoring team. The teams assets are used in all 10 EPA Regions for removal and remedial projects. ERT’s equipment involves real-time sampling instrumentation, as well as sampling media to be analyzed by the team’s dedicated fixed lab, mobile labs or contract laboratories. The real-time data can be collected and used by the Viper Data Management System Exit. This system allows management of multiple instruments across various platforms and allows a user to interpret data in the field. ERT’s resources can be mobilized within hours of an event and can autonomously collect data for hours and even days. Whether a situation calls for an emergency response or a long-term cleanup, ERT’s instrumentation can be on site and collecting data/sampling.

ERT’s air instrumentation can be used to sample for chlorine, hydrogen sulfide, cyanide, ammonia, phosgene, volatile organic compounds, benzene, metals, asbestos, particulates and other chemicals of concern at part per billion (ppb) levels. Their expertise and guidance has been relied on during many high-profile environmental cleanups, including the Deepwater Horizon oil spill, the Kalamazoo oil spill, Minot flooding and Hurricane Sandy responses. ERT’s air systems have been deployed at many Nationally Significant Events (NSE) – Super Bowls, Democratic and Republican national conventions, presidential inaugurations and others – providing real-time consequence management and sampling capabilities.

ERT is also developing their Snapper remote sampling system that will allow air samples to be taken by remote triggering so responders can take a sample without being in harm's way.
