Depending on the severity of the contamination, the following cleanup activities may Deed to be conducted;36 A. Before Cleanup Before cleanup begins, officials should first conduct a pre-cleanup assessment of the drugs manufactured, the chemicals found, drug pro<iuction metbods used, production locations, and disposal locations at the site. J7 This assessment should include testing and evaluation of suspected contaminated areas.38 Assuming the site assessment shows that cleanup is needed, officials should then evaluate the different cleanup requirements for the site. 39 B.

Therefore, the Minnesota Department of Health recommends the following: A post-cleanup assessment should be made by a health professional with training in clandestine laboratory cleanup in consultation with the contractor hired to prirm the decontamination work, and with input from the law Dr drug enforcement agency involved. This assessment should verify (when possible) that the site has been cleaned according to the cleanu~ guidelines established by the Minnesota Department of Health I and that contamination has beel! reduced to levels expected to be non-toxic.52 No one should rent, purchase or - 5.
