We had a company up here - Holtra Chem that for years leached huge amounts of mercury into the Penobscot river. Its people said there was no problem. It took the courts and finally the state (with public urging) to get them to clean it up- and it still is incomplete.
The state likes to do business its way. The state EPA used to say portions of the Penobscot river were fine- met expected safe levels. The Penobscot Nation, located on an island in the Penobscot river thought otherwise as they were downriver from a papermill. The algae bloom was readily visible for miles down the river coming from the mill. The Penobscot Nation hired people to take water samples and sent them out to a lab. Their results were inconsistent with the state's results. This went to court and with further testing the state EPA admitted their results were incorrect, and they started some clean up of the contamination.
These two situations resulted from maintaining the "status quo". The state "protected" the mill and Holtra Chem until public pressure and the courts were involved. The state protected the status quo- rather than adopting a pro-active attitude to protect the lives of its citizens. (Doesn't help that Maine has the highest cancer rate in the country).
In this state the bluberry fields are sprayed (pesticides) from the air. The pilots are frequently not paying attention to the weather, just inaccurate, or whatever, but spraying residences as well. People complain of feeling ill from this, and the state tends to look the other way. Our local international airport used to spray deicer on the wings in heavy doses. It went down the storm drains and made it into the local Kenduskeag river. Residents along the river would complain of the smell and headaches. This went on for years before it was finally tested for and addressed. Today the airport employs a recovery system to keep the de icer out of the local river.
People always protect the status quo.
Why don't we require business to prove a product/process is safe, before they can use it in their operations. Why do we wait for illness to become evident, biological impact to be evident before we begin to investigate. The lag time runs 10-20 years. That is a lot of impact time.
Just think if the FDA operated in that manner- think of the drugs (untested) that would be available + the effects.
That is what we are doing with everything else- waiting until the illness/catastrophe reports come in before we'll address potentially toxic situations.
