More extensive testing during the weekend proved the town water in Hugo, CO, does not contain any THC, the psychoactive ingredient in marijuana, as was reported by public officials last week. A shed covering a town wellhead was broken into, but the Lincoln County Sheriff’s Department has not been able to determine when the break-in occurred and does not know who did it. Hugo residents were warned going into the weekend not to drink the town’s water because some tests showed the presence of THC in the water. Officials say those results were false positives. The warning was lifted on Saturday with a situation update that was posted on the sheriff’s Facebook page. Hugo, a town of 730, is located 110 miles southeast of Denver on the state’s Eastern Plains. Tests kits that reported false positives are being returned to the manufacturer to determine why they were defective. “There never was THC in our water supply, “sheriff’s department Capt. Michael Yowell said. “We did get multiple tests showing the possibility of THC, but independent tests taken by different people at different times and places showed no evidence of THC.” While recreational marijuana has been legal in Colorado for more than two years, Hugo has not approved any licensing, which is done at the local level. That means cultivation, manufacturing, testing, and retails sales of marijuana are all banned in Hugo. During the Thursday to Saturday period covered by the water warning, bottled water was trucked into the community. The Lincoln County Sheriff’s Office said in its Thursday post on its Facebook page that the Hugo Public Works staff notified it of the test results showing THC in the water supply. The all-clear came from the Colorado Bureau of Investigation on Saturday. “The criminal investigation regarding the tampering and forced entry at Hugo Well #1 will continue by the Lincoln County Sheriff’s Office,” according to the Saturday Facebook post. “Any information regarding the criminal mischief investigation will be made available to the public when we are able to.” (To sign up for a free subscription to Food Safety News, click here.)
