It doesn't appear vinyl chloride wants to stay in water, based on the numbers I'm seeing (https://semspub.epa.gov/work/05/437069.pdf https://semspub.epa.gov/work/05/437069.pdf). The instances of vinyl chloride contamination tend to be from an actively-producing source, like a plant with a leak. Spilled on the ground and absorbed into water, it should evaporate into gaseous form in a matter of hours.
