The problem with using the Love Canal was that it was the local government that really fucked up.
For the time, Hooker Chemical Company disposed of the chemical waste in a somewhat responsible way; a clay lined canal that they later topped with clay to prevent water infiltration. If the town wasn't dead set in developing the land, we likely would have never heard of Love Canal.
The company did the dumping and then sold it off for $1 for a school to be built upon it. They were held liable. They also created other environmental disasters elsewhere. White Lake Michigan, for instance.
Hooker Chemical Company gave no fucks, and should not be given tacit approval or any credit.
Hooker Chemical sold for $1 and a list of conditions because the local government was threatening eminent domain after the company gave several warnings.
And I'm not going to defend Hooker in other locations.
They were forced to sell under threat of eminent domain. That's why they tried to sell it for $1 along with a list of conditions on what it could be used for to highlight the danger. The Government then rejected this offer. Rather than trying to blame some random company just because you think all companies are evil, maybe go and read the history instead.
More importantly it was the 1950s before the Clean Water Act. Where both entities involved existed under the framework of industry self-regulation that is being directly criticized here.
The issue isn't a company or government is responsible: it is that the system of self regulation results in failures with significant collateral damage.
Regulation also binds government, believe it or not.
