IV. ANALYSIS AND RESULTS <br /> A. Specifications <br /> All samples were handled and analyzed in accordance with EPA methods as noted on the <br /> laboratory documentation. <br /> V. FINDINGS <br /> A. General <br /> All reported chemicals, equipment and by-products of the clandestine activities were <br /> removed by law enforcement prior to the'site inspection. Laboratory analysis of the <br /> submitted samples indicated the presence of Methamphetamine (via method HPLC-UV by <br /> USP # 24) as well the precursor Naphthalene (via EPA method 8260B) in the surface <br /> wipe samples collected. <br /> B. pH <br /> Samples were analyzed for pH to assess acid and alkaline contamination associated with <br /> the use of corrosive chemicals. The pH scale is a logarithmic scale, ranging from 0 to 14, <br /> used to characterize corrosivity. A pH value less than 7 suggests an acidic material, <br /> whereas a pH greater than 7 is indicative to caustic (basic) materials. The sample result <br /> was 8.01. The sample results appear to be only slightly caustic. <br /> C. Phosphorous <br /> 3 <br /> Phosphorous has an established exposure limit of 0.1 milligrams per cubic meter (mg/M) <br /> of air. Along with iodide, it is capable of producing eye, skin, nose and respiratory tract <br /> irritation along with chest tightness, headaches, stomach pain, birth defects, jaundice and <br /> kidney damage. The recognized target organs are eyes, skin, respiratory system, central <br /> nervous system, liver, kidneys, blood and cardiovascular system. No Phosphorus was <br /> identified in the sample'collected. <br /> C. Iodide <br /> Iodide has an established exposure limit of 0.1 parts per million (ppm) in air. Iodide is <br /> capable of producing eye, skin, nose and respiratory tract irritation. It may also produce <br /> jaundice and kidney <br /> damage. The <br /> chest tightness, headaches, stomach pail, birth defects,,l <br /> recognized target organs are eyes, skin, respiratory system, central nervous system, liver, <br /> kidneys, blood and cardiovascular system. No Iodide was identified in the sample <br /> collected. <br /> ESS Project 2003712-1 <br /> Page 4: <br />
