Description

The Craig Radio Station was operated by the U.S. Army Signal Corps from 1918 to 1962 on Tracts A&B at the corner of Main Street and Fourth Street in Craig. From 1962 to 1971, the U.S. Air Force used the site for a telephone and telegraph station. The facility consisted of a communications center building with personnel quarters, operations building, generator building, large and small antenna, water tank, underground storage tank, and utility lines. Portions of Tract A are currently owned by Shaan Seet, Inc. and AT&T Alascom, Inc.; and Tract B is privately owned.


The U.S. Army Corps of Engineers conducted a site visit in February 2004 and collected samples from the 3 remaining underground storage fuel tanks. In August 2004, the Corps of Engineers drained and removed the fuel tanks. The tanks and 20 cubic yards of contaminated soil were disposed of out-of-state. In November 2004, the Corps of Engineers conducted a Remedial Investigation which included installing and sampling 5 groundwater wells and collecting soil, sediment and surface water samples in order to determine the nature and extent of contamination. Based upon the sampling results, it appears that the petroleum soil contamination is fairly limited in extent mainly in the area around the former tanks. Elevated levels of petroleum were noted in the groundwater to be more widespread.

 


Public Health and Environmental Concerns

 

High concentrations of benzene and diesel-range organics were found in the soil, and high concentrations of benzene and gasoline-range organics were found in the groundwater. Most of the contamination in the soil is present in the area where the former tanks were located and is approximately 4 feet below ground surface and covered with clean uncontaminated fill. The groundwater contamination at the site is not used for drinking water. The groundwater is migrating off-site.

 


Current Status

 

The Corps of Engineers in currently finalizing the Remedial Investigation report. In Spring/Summer 2005, ADEC and the Corps of Engineers will be discussing what appropriate actions need to be taken in order to address the remaining contaminated soil and developing cleanup levels. Long-term monitoring of groundwater will be conducted.
