r 30 January 2019 AdvancedGeo AGE Project No. 18-4574 Environmental Page 4 of 7 Methamphetamine concentrations exceeded the limit of 1.5 micrograms per 100 square centimeters (pg/100 cm2) in all of the wipe samples collected within the property residence, at concentrations ranging from 3.0 pg/100 cm2 (Master closet wall) to 1,700 pg/100 cm2 (Kitchen sink). The results are summarized in the attached Sampling Results Table. The highest level of contamination was reported in a surface -wipe sample collected from the kitchen sink facet. Additionally, elevated levels were reported in samples collected from bedroom 1, the guest bathroom, the master bedroom, and the kitchen. Although field evidence suggests bedroom 1 as the main methamphetamine conversion (or cooking) area, relatively higher concentrations were reported throughout the residence. This suggests that the entirety of the property was utilized for handling of chemicals and product. A copy of the ALS Environmental laboratory report (Work order No. 34-1901661) and chain of custody form are included as Appendix A. 3.0.
