What has changed?

For the past several months as the collected wastewater has gone through the system, sample results have shown that the wastewater meets the standards set for vinyl chloride and other derailment-caused contaminants without treatment, meaning it can be disposed of as non-hazardous waste.

Testing of the collected wastewater will continue, and all water will have to meet the same standards (drinking water standards for vinyl chloride) before it is disposed of as non-hazardous waste. All collected water will still be properly disposed of at an approved off-site treatment facility.
