Rules to cleanup Falls Lake are set, but the important source of water remains a mess. The water is not swimmable or drinkable and does not meet water quality standards set by the EPA. Raleigh and Durham are fighting over who is responsible and who will pay for the cleanup. Durham questions whether the cleanup is worth the cost and Raleigh supports the cleanup and plan as Falls Lake supplies water to the city. The details of the plan, the history of the disaster, and the fight over it are explained.
