From 1963 – 1977, Maxey Flats in Kentucky accepted nuclear waste for disposal. Since 1977, the site has been an on-going cleanup and monitoring site. A geomembrane cap was installed to prevent further incursion of water after 900,000 gallons of leachate was extracted, and a final cap is planned. Today, the site is considered much safer and is welcoming visitors to observe and learn about the environmental controls.
