July 18, 2025 - Coal ash, also known as coal combustion residuals (CCRs), is the toxic ash left behind from burning coal and can pollute waterways, groundwater, drinking water, and the air with harmful chemicals such as mercury, cadmium, chromium, and arsenic. In Georgia, there are 24 federally regulated coal ash ponds and landfills containing nearly 87 million cubic yards of toxic waste at nine coal plants. All but one of these sites have contaminated groundwater.
This decision comes as the Georgia Environmental Protection Division (EPD) is considering allowing coal ash to be capped-in-place at Plant McDonough, leaving the toxic ash in an unlined pit with no barrier to prevent it from seeping into groundwater below.
