THC isn’t even soluble in water. Sounds like some private company was using a cheap drug test and someone decided to test some tap water to show a negative result. Unsurprisingly, the cheap test showed a positive result. If it turns out the drug tests have gotten someone fired, I hope that someone gets a good lawyer and sues.
But hey, no reason to wait for facts, let’s start a panic!
Colorado has had problems with water quality though. While they’re testing the water, maybe they’ll test it for whatever else might be in it. Could be educational.
Unless they find some CBD-only company has been dumping the THC they recover and can’t use, the amounts in the water would have to be so small as to be laughable. Since there’s zero toxicity and you’re not getting high from these amounts, the warning is less necessary than warning people about the level of blood pressure medicine and birth control in their water (and yes, that stuff is present in the water you drink).
