Copy/Paste of Dan River Coal Ash Spill for editing
Reasons for spill
The cause of the ash spill was described by EPA as a limited structural flaw.[1] A storm pipe nearby the deposits of a coal ash slurry containment area broke and allowed for the leakage.[2] Coal ash slurry is produced during the process of burning coal. It is the left over impurities that stick around after burning coal for electricity.[3] Coal companies have found that the cheapest way to store this waste is to mix it with water and store it in a pond. These ponds have been found to have leaks that can dispose hazardous material into surface water among other things.[3] This material was released into the Dan River because of the collapse of a 48 inch drain pipe.[2] The pipe was made of concrete and corrugated metal and reason for the fracture cannot be identified.[2] What resulted was 39 thousand tons of coal ash and 27 million gallons of ash pond water were deposited into the Dan River.[2]
