HUGO — Officials in a small Colorado town say well water has been contaminated with marijuana's psychoactive chemical. Authorities are telling residents of Hugo, about 100 miles southeast of Denver, not to shower or drink the water because of evidence of marijuana's intoxicating ingredient THC. A spokeswoman for the Colorado Division of Emergency Management, Micki Trost, says state investigators are headed to the scene. She did not know the source or extent of the contamination.
