Often, pollution is invisible. It’s in the exhaust particles we breathe walking past traffic, or the traces of mercury in Kentucky fish. But at the Green Station Landfill in Webster County, it’s obvious.
At times, the coal ash leachate shimmers black like an oil slick. At other times, it oozes chemical green. Sometimes, it stains the soil the color of rusted molasses. And in videos, the coal ash liquids trickle off the landfill like teal glacial waters leaving behind a pale salty residue.
