Last week, a federal court held the Tennessee Valley Authority (TVA), the nation's largest public utility, responsible for a massive 2008 coal ash spill near Kingston, TN, that released 5.4 million cubic yards of sludge into the surrounding community. Coal ash can contain arsenic, lead, chromium, and other toxic substances, which many Kingston area residents say contaminated their properties. The decision could provide compensation for many harmed by the spill, but better public protections to prevent these types of spills are still needed.
