A warning not to drink the water in the town of Hugo has been canceled after additional tests showed there is no longer any evidence of a marijuana chemical in the tap water.
The Lincoln County Sheriff’s Office said Saturday that a criminal investigation is continuing into suspected tampering and forced entry at a Hugo community well, but a second round of testing on the water turned up no trace of THC, the psychoactive ingredient in marijuana.
Bottled water was distributed to residents of the town last week after officials said that some field tests for the chemical turned up positive. Residents were even cautioned against showering in the water. Authorities are contacting the manufacturer of the test kits to find out why some tests came back positive.
No illnesses have been linked to the suspected contamination, according to Lincoln County Public Health Director Susan Kelly.
The investigation has been turned over to the Colorado Bureau of Investigation.
