A meth lab is an illegal drug manufacturing site containing materials required to manufacture meth.
Meth is made from common household items that are readily available at supermarkets and hardware stores. When these ingredients are mixed together or "cooked" to produce the drug, they generate a large amount of chemical waste. This waste is typically dumped down the drain, but may be stored, buried, or dumped elsewhere on the property.
Surfaces in the residence may become contaminated with this waste and be corrosive. If not properly decontaminated, residual wastes can remain on surfaces for years. This is why meth labs are considered hazardous and should only be handled by hazardous waste professionals.
Meth labs can be set up nearly anywhere, but are most commonly found in motel rooms, apartments, and rental properties. Other locations may include storage units, RVs, sheds, garages, vacant buildings, and campgrounds.
