Can you please summarize this?
I added info @ the post.
Sorry, fell asleep while researching.
The navy created a method to breakdown really nasty compounds. What they learned in a multi-contaminated site is Oxygen and Methane worked. Imagine that! Groundwater can be decontaminated by injecting the two gases to create a biofilter.
The groundwater can be restored, and without digging up the sites.
Regarding the burn off using chemicals:

Barium carbonate promoted cobalt oxide as highly efficient catalyst for the total oxidation of vinyl chloride
The compound totally clears vinyl chloride. Seems CO2 is a byproduct.
The problem is that this was not utilized in the East Palestine case. It's all 'water under the bridge' and too late.
You mention the "burn off using chemicals", which is oxidizing.....Barium carbonate reacts with acids such as Hydrochloric acid (HCl) to form soluble barium salts, such as barium chloride. The vast majority of the gaseous vinyl Chloride (VC) was burnt and the resultant oxidation process re-associated into HCl when it came into contact with water vapor in the atmosphere. What could have remedied these HCl acid forming clouds is to have immediately aerially sprayed the skies with neutralizing agents much like the forest fighting aircraft do fighting fires. Instead, government has decided to do the worst thing and cover it up by saying -- "There's nothing to see here. Return to your homes and forget about this." Albeit, VC was the bulk of the hazardous material affecting the environment, it wasn't the only chemical spilled.
Yes, they failed to respond. They are also failing to protect the people by not advising the town the train was on fire before it crashed. We are seeing multiple levels of failures.

Part A. Bioremediation of Halogenated Compounds. Abstract : Prior work at Naval Base Ventura County, Point Mugu used anaerobic in situ bioremediation to achieve volumetric treatment of a trichloroethene/dichloroethene (TCE/DCE) plume in groundwater with high sulfate concentrations (approximately 700 mg/L). Complete dechlorination of TCE and DCE was achieved rapidly but the vinyl chloride (VC) intermediate was degraded at a very slow rate, resulting in a VC plume that persisted after the anaerobic treatment. To accelerate treatment of this residual VC, a novel treatment strategy was implemented using aerobic cometabolism. Treatment cells with 4 extraction wells surrounding a central injection well were operated in a pulsed injection flow strategy. Methane and oxygen were injected with contaminated water to create an in situ biofilter zone around the injection well. Process operations consisted of a methane/oxygen distribution stage with a high groundwater recirculation flow rate and a reaction stage where the recirculation flow was stopped. This strategy was configured to optimize the cometabolic methanotrophic reaction by addressing the need to efficiently distribute methane and oxygen within the in situ biofilter, allow for growth of methanotrophs, and minimize methane inhibition of VC destruction. Initial operations with a single treatment cell successfully demonstrated VC destruction with this in situ biofilter pulsed injection strategy. The system was then expanded to include three treatment cells operated on a rotating cycle. The configuration of the three cells was designed using reactive transport modelling with the objective of treating the entire VC plume remaining from the original anaerobic bioremediation treatment of TCE and DCE.

Ya real smart kid, so am I. Explain it to me like I’m 5 or it doesn’t fucking matter. That’s the bitch of it, being a scientist or whatever. You can absolutely understand and follow some of the worlds most complicated concepts but until you can dumb that shit down to the general population, it’s for not.
Where we go one, we go all!
Sorry man, fell asleep. I added the summaries @ the post.

Here the studies show they perfected the use of injected materials that off gas oxygen to degrade vinyl chloride (VC). The local bacteria also broke down the VC.

This study in particular shows how using a substance that slowly off gasses Oxygen along with local bacteria broke down the vinyl chloride.
