It’s named after 7-year-old Zane Gbangbola who died after floodwater entered his home in Chertsey in 2014.
His parents Kye and Nicole say he was killed by toxic gas from the nearby dump after the River Thames burst its banks.
However, a coroner ruled that he died from carbon monoxide from a petrol-powered pump used to clear flood water.
Zane’s Law would ensure that all potentially contaminated land is identified, made public, regularly inspected and properly cleaned up.
Councils would be given the funding, resources and powers to act, where those responsible for the pollution can be identified.
