In the absence of transparency, misinformation is filling the void.
State officials disclosed that a plume of contamination released into the nearby creek had made its way into the Ohio River. Other cities get their drinking water from the river, and wereabout the risk. The farther this plume moves downstream, the less concentrated the chemical will be in water, posing less of a risk.
How long can these chemicals linger in soil and water, and what’s their potential long-term risk to humans and wildlife? Booms in a nearby stream have been deployed to capture chemicals. Air-stripping devices have been deployed to remove chemicals from the waterways. Air stripping causes the light chemicals to leave the water and enter air. This is a common treatment technique and was used after an 2015 oil spill in the Yellowstone River near Glendive, Montana.
Incineration is one way we dispose of hazardous chemicals, but incomplete chemical destruction creates a host of byproducts. Chemicals can be destroyed when heated to extremely high temperatures so they burn thoroughly. The EPA has been screening homes near the derailment for indoor air-quality concerns. How do these chemicals get into homes and what happens to them in enclosed spaces?
