I went to college in Salem. Shortly after i graduated they started the clean up process.That is very interesting, as I never saw that color in the water.
The coal mines in the area where I lived had methane gas (very deadly).
When and where did you live there?
Methane gas is no more deadly than any other gas. The main deadliness is the lack of oxygen. Even Nitrogen (78% in the air we breathe) is deadly if no oxygen is present.
Hydrogen Sulfide is the deadly killer.
