The former Waverly Air Force Radar Station is located in northeast Iowa south of the city of Waverly, Bremer County, Iowa.

The former Waverly Air Force Radar Station is located in northeast Iowa south of the city of Waverly, Bremer County, Iowa.

Location and Description: The former Waverly Air Force Radar Station is located in northeast Iowa south of the city of Waverly, Bremer County, Iowa. It can be accessed from State Highway 218 at 250th Street. The property is in private ownership and is currently used for rental apartments and cattle grazing. 

Problem and Response: Soil and ground water contaminants remain at the location of a leaking underground storage tank removed at Building 203. An in situ chemical oxidation (ISCO) remediation was performed in the third quarter of FY12. The horizontal treatment area was approximately 27 feet by 27 feet, and the vertical treatment interval is 5 to 15 feet below ground surface. The selected remediation for addressing the benzene, toluene, ethylbenzene, and xylene impacts to groundwater at the site was ISCO. The second post-inspection of the monitoring well continues to demonstrate that the ISCO was successful at significant reduction of the benzene concentration and removal of all detectable toluene, ethylbenzene and xylene. The benzene concentration [19.2 micrograms per liter (μg/L)] was slightly above the site-specific target levels of 7 μg/L. The regulator, Iowa Department of Natural Resources (IDNR), indicated that additional remediation/monitoring is necessary for the site. 

Proposed Activities for 2016: Continue to resolve actions necessary to get site closure with concurrence from IDNR.
