I am writing in response to the article about winter road-clearing operations. Spencer County uses cinders, a form of coal ash. Coal ash is the waste that is left after coal is combusted.
Now, this letter is not an attack on coal. I am just providing the facts about what is left after you burn coal. Coal ash typically contains heavy metals including arsenic, barium, lead, mercury, cadmium, chromium and selenium, to list a few. If inhaled, these toxins can cause cancer, respiratory distress and other health issues.
