HUGO, Colo. -- Tests of the water supply in Hugo by the Colorado Bureau of Investigation have come back negative for THC, two days after initial local testing prompted a water advisory.

The advisory has been lifted and residents in the eastern Plains town can drink and cook with the water.

The Lincoln County Sheriff's Office said it's believed initial tests that showed THC in the water were a false positive.

However, one of the well houses associated with the water supply showed signs of tampering and the sheriff's office is continuing its investigation.

The initial reports on Thursday that THC, the active ingredient in marijuana, was detected in the water supply attracted national attention.
