• TIMELINE: Lac-Mgantic rail disaster

Quebec Environment Minister DavidHeurtel released the findings of an expert committeeon the state of theChaudireRiver at a news conference in Sainte-Marie, Que., on Monday morning.

An estimated 100,000litres of oil spilled into theChaudireRiver in July and Heurtel said that despite efforts to clean the riverbanks and sediment,a 30-kilometre stretch of the river still has considerable levels of oil along the bottom of the river.

So far, the province has spent$16 million to clean up the river andHeurtel said there's still work to be done if the river is toreturn to its original state.

"We're talking about not only the water itself, but along the banks, and everything that's involved with that," Heurtel said.

"It's going to take time, but we want to do the right thing ... it's a long process and it is very costly."

The report released today also recommendsseveral priorities as the cleanup work progresses.

Recommendations for 2014-15

• Release an up-to-date portrait of presence ofpetroleum hydrocarbonscontamination in the river's sediment.
• Document the level of toxicity in the river's sediment.
• Pinpoint segments of the river where contamination levels are high enough toposea threat to the ecosystem.
• Identify the environmental impacts of different cleaning methods and outline an intervention plan.
• Ensure environmental monitoring of the river.
