The Coast Guard and other agencies are finished cleaning up oily water that discharged into the Piscataqua River earlier this week.
The Coast Guard says the discharge came from the National Oceanic and Atmospheric Administration's Ferdinand R. Hassler ship on Tuesday. The Coast Guard says clean-up concluded on Thursday with assistance from NOAA, the New Hampshire Department of Environmental Services and Enpro. Assessments of the shoreline found no impacts to wildlife.
The Coast Guard says the cause of the spill remains under investigation. The Ferdinand R. Hassler and an affected sailboat have both been cleaned.
