A nearly three million dollar clean-up of the former Iowa-Nebraska Light & Power manufactured gas plant site will get underway next week.
The Environmental Protection Agency says the building will be demolished, soil will be excavated, and then new soil will be backfilled at the corner of Norfolk Avenue and 7th Street in Norfolk.
The clean-up is estimated to cost $2,835,000. It begins Monday.
Streets will be blocked off periodically during the time of the clean-up, expected to last until April.
Excavation will dig to a depth of 10 feet below ground surface, unless soil samples indicate the dig must go deeper to remove contamination.
The EPA says soil contamination at the site includes coal-tar-contaminated materials including but not limited to:
volatile organic compounds (VOCs), including benzene, toluene, ethylbenzene and xylenes (BTEX); semi-VOCs, including polynuclear aromatic hydrocarbons (PAHs); and metals.
Groundwater contamination includes coal-tar-contaminated materials including but not limited to:
VOCs including benzene; PAHs; and dense nonaqueous phase liquid.
