The unlawful manufacture and use of methamphetamine continues to be an epidemic throughout Tennessee. Law enforcement agencies in every county have encountered Clandestine Methamphetamine Laboratories (CML), numbering in the thousands statewide. CMLs have been found at all types of properties including single-family homes, rental properties, hotel and motel rooms, automobiles and other vehicles. These laboratories always leave behind hazardous residues which pose a threat to human health. In many instances, these manufacturing residues, including methamphetamine, render property 'Unsafe for Human Use' and can be found on hard surfaces such as walls, floors, ceilings, furniture, fixtures, and appliances and soft surfaces, such as carpeting, curtains, bedding, and clothing. Anything in close proximity to “cooking” meth can get contaminated. To address such a widespread threat to the health of Tennessee citizens, the Tennessee Department of Environment & Conservation (TDEC) Division of Remediation (DOR) has developed rules to determine when a property is no longer 'Unsafe for Human Use' due to methamphetamine contamination.
