Description
The contaminated site is the base of operations for the Southeast Regional Office of the Alaska Department of Transportation & Public Facilities (ADOTPF). The facility operations include a large vehicle maintenance shop, a materials testing laboratory and two office buildings.
Public Health and Environmental Concerns
Petroleum contamination will likely continue to dissolve into and migrate with groundwater; petroleum vapors will continue to migrate along soil vapor pathways. The elevated vapor concentrations have potential to impact ambient air in occupied buildings downgradient of the contamination sources. Consistent monitoring is essential and possible active treatment should be considered.
Current Status
Vapor badges were placed in six locations to screen for benzene in the ambient air of the office buildings in 2003; results were non-detect. Elevated concentrations of gasoline range hydrocarbons and benzene were detected in water samples from five of the monitoring wells and elevated concentrations of diesel range hydrocarbons were detected in seven of the wells located at former UST sites. Additional groundwater monitoring and field tests of ambient air in occupied buildings are planned. The temporary contaminated soil stockpile will be removed and remediated off-site as soon as possible.
