According to a public service announcement, small amounts of fluid “released from the helicopter have been noted in the water within the containment area and have been removed.” A contractor has been monitoring contamination through water sampling of the crash site. As of Tuesday afternoon, Lavallee said sampling hasn’t found any contamination along the riverbank or beach. “We have some specialized equipment on site, on the river, to contain any fluids like lubricants, or fuel, or any contaminant that may leave the aircraft into the water to prevent that contamination from getting into the wider environment. There has been some evidence of some small amount of fluids that have come out of the helicopter, but it’s all been contained by this specialized equipment.”
