III. PROCEDURE'S <br /> A. Sampling. <br /> Based on the site observations and previous site inspections, a sampling plan was devised <br /> to assess possible contamination from chemicals commonly used in the manufacturing of <br /> Methamphetamine. Suspect areas sampled include: the kitchen counters and hard floors. <br /> The entire dwelling was visually inspected for any signs of staining or odors o unusual <br /> staining or odors were observed in the dwelling or garage with the exception of t e <br /> kitchen. The dwelling is on a septic system, however at your request this system was <br /> excluded from the current scope of work. Surface wipe samples were collected from the <br /> areas most likely to be -ed or illicit drug man_ufacturin�. The samples were analyzed for <br /> the presence of Methamphetamine and its precursors. See attached laboratory <br /> documentation for the EPA analytical procedures used. . <br /> All sample locations were selected based on professional judgment, which was based on <br /> the reported usage of the areas, visual observations and visible surface staining. <br /> • All wipe samples were taken with a 12 inch by 12 inch sterile "ghost wipe". Wipe <br /> samples were taken by wiping approximately 12 square inch surface areas. <br /> • All samples were subsequently placed into individual plastic bags, which were sealed <br /> and labeled. The samples were forwarded via Federal Express overnight to <br /> CZARTECH Analytical in Novi, MI and CLS of Rancho Cordova_ <br /> Chris Hintz REA, SST, CIAQI, CIE Operations Manager and Industrial Hygienist conducted the <br /> site inspections and sample collections on October 13, 2003. <br /> C. Observations <br /> The following observations were noted on October 13, 2003 at the time of site inspection <br /> and sampling. <br /> 1. The kitchen floor and stove top area exhibited yellow staining. <br /> 2. Most horizontal surfaces in the kitchen exhibited surface dust or powder <br /> accumulation. <br /> 3. Various contents were present throughout the dwelling.�ting and Pad was <br /> g room. No unusual observations were noted <br /> present in the bedrooms and livin <br /> in these areas. <br /> 4. No unusual observations were noted in the garage. <br /> 5. Other noteworthy observations of the property include multiple areas of <br /> possible soil contamination to the rear of the dwelling from abandoned vehicles <br /> and automotive parts. <br /> ESS Project 2003712-1 <br /> Page 3 <br />
