Environmental Assessment Work Group (EAWG) for WTC - Roles and Accomplishments

The Environmental Assessment Work Group is lead by three chairpersons representing EPA-OERR, ATSDR, and OSHA. Although a larger number of agencies and offices (e.g., NYC DOH, NYC DEP, NY DEC, NIOSH, EPA-Region 2, EPA-OEI) actively participate in the weekly, twice/week calls and product development. The EAWG which was formed the weekend following September 11, provides direct assistance to New York City to supplement the critical day-to-day work conducted by Region 2, NYC, New York State, and OERR's Environmental Response Team (ERT). In order to understand NYC's needs and communicate with other players, EAWG members also participate in New York City's twice/week data analysis reporting calls (originally these were daily).

To date, the EAWG has accomplished the following:

Coordinated with Region 8 on short term analytic and risk approaches for asbestos used for Libby and the WTC;

Worked with EPA's Office of Environmental Information (OEI) to establish a Multi-Agency database for daily sample analysis results. OEI also provides data entry and data management of this vast database (over 500,000 data points/parameters just for the asbestos data) ;

Provided asbestos air samples and TAGA organic analyses data in electronic format to the city and state while OEI developed the database;
