Meth Contamination

The abuse and manufacture of illegal methamphetamine continues to be a statewide epidemic in Tennessee. Law enforcement agencies across the state have encountered thousands of Clandestine Methamphetamine Laboratories (CML) from 1998 to present. CMLs are found on all types of properties ranging from single-family homes, rental properties, hotel and motel rooms, automobiles and other vehicles. No matter where these laboratories are created or used, they all leave behind hazardous residue, which poses a threat to human health. In many cases, this methamphetamine residue renders a property 'Unsafe for Human Use' and can be found on hard surfaces, like walls, furniture, appliances and ceiling fans, and soft surfaces, such as carpets, drapes, bedding, clothing, and toys.

Since numerous properties have been affected, Tennessee Code Annotated 68-212 Part 5 allows the Tennessee Department of Environment & Conservation (TDEC) to develop rules to determine when a property is 'Safe for Human Use' again. TDEC evaluated the risks posed by residual contamination and has developed reasonable, appropriate and protective (RAP) Cleanup Guidance to decontaminate properties affected by CMLs. TDEC's RAP Cleanup Guidance along with its Tiered Cleanup Responses are based on the premise that as more and more methamphetamine, meth-making ingredients, or reagents are manufactured at a CML, the greater the potential is for more residual contamination to remain on the property that will need to be cleaned up.
