Apparently someone thought leaving poisonous chemicals next to flood debris in Lyons
would go unnoticed. Now, the Boulder County Sheriff's office is investigating two incidents of illegal chemical dumping in Lyons.

On Nov. 7, police say someone dropped off a 30-gallon barrel containing zinc cyanide, an extremely poisonous chemical, at Black Bear Inn in Lyons. Four days later, police say a similar discovery was made at an Environmental Protection Agency dump site on 36th and 66th streets. It was later determined the chemical inside the 20-gallon barrel was copper cyanide, which is also extremely toxic.

Police believe someone is dumping the toxic waste next to flood debris hoping no one will notice. Police are asking anyone with information to call the Boulder County Sheriff's office.
