IA’s are joint projects between FDEP PTSS, EPA SESD and the EPA Emergency Response and Removal Branch (ERRB). Sites subject to an Emergency Response or Removal are targeted. The IA’s involve contamination assessment including groundwater assessment, soil assessment and/or surface water assessment. Data acquired during the IA is used by EPA ERRB to determine the best appropriate remedial response. Many of the ERRB projects can be found at this link. http://www.epaosc.org/site/regionmap.aspx
