Did I hear correctly that the EPA instructed them to disperse chemicals into the air rather than into the ground? Anyone got details on this?

- rzzzt 6y agoIt was a water spray (Bil said "aerators" around 0:44; he probably did not mean the spiky lawn care thing, but rather a sprinkle system), to keep the existing chemicals on the ground from turning into dust and flying further away. (At least that is my understanding.)
- ncmncm 6y agoThere are a lot of Superfund sites with toxic, volatile chemicals in the ground. They soak water into the ground, which dissolves the chemicals, then they pump water up from a well and spray it in the air to evaporate and dissipate the chemicals. Exposure to oxygen and ultraviolet light from daylight breaks up the molecules, over time. It is not healthy to be around that spray. That has not stopped people from building housing complexes around exhausts from similar operations in SV.
