Coal Ash Pond Remediation

Coal ash can be disposed of in two main ways: by placing it in a dry landfill, or dumping it in a surface pond. The issue posed by dry landfills is that the wind can carry away this toxic coal ash and cause pollution (i.e. acid rain). Coal ash ponds trap the ash so that it cannot be carried away by the air, however it does pose issues of its own.
