How Does a Property Become Meth Contaminated in Montana?
While this may seem like a straightforward question, right? It’s actually a little more nuanced than you might expect.
meth test in houseTo be legally recognized as meth contaminated in Montana, a building must test positive for over 0.1 micrograms of meth per 100 square centimeters — the lowest legal standard in the United States. This
level is around the average trace that can be found on common items like ATMs, shopping carts, and money. States outside of Montana have looser regulations, including California (1.5/100 square centimeters), Colorado
(0.5), and Utah (1.0).
The most widely recognized means in which a property becomes meth contaminated is the presence of a meth lab. Once a property has been found to hold a lab, it is placed on the Montana Department of Environmental
Quality’s public list indefinitely, regardless of cleanup status. This list, however, does not include properties that have been contaminated through resident smoking.
The truth is, consistent methamphetamine use in a building can cause higher levels of meth contamination than a lab. Similar to tobacco smoke contamination, meth smoke will often enter a building’s cold air return — then
the furnace distributes the smoke throughout the home.
