1. INTRODUCTION <br />The City of Santa Ana retained Lead Tech Environmental ( "LTE ") to conduct a limited <br />lead -based paint ( "LBP ") survey of a single family residence located at 714 E. e Street, <br />Santa Ana, CA referred to as the ( "Residence "). LTE conducted its survey in accordance <br />with the Department of Housing & Urban Development ( "HUD ") document entitled <br />Guidelines for The Evaluation and Control of Leary Based Paint Hazards in Housing, <br />1997 edition. <br />The HUD Guidelines and State of California define X -Ray fluorescent analyzer ( "XRF ") <br />measurements greater than or equal to 1.0 mg/cm2 (tri[th rams per square centimeter) <br />positive for lead based paint. <br />Mr. Steven Denzler conducted LTE's LBP survey on June 4, 2009. Mr. Denzler is a <br />California Certified LBP Inspector (1- 1261). <br />2. BtiILDING DESCRIPTION <br />The Residence was a single -story structure built in the 1920's. It contained four <br />bedrooms and two bathrooms. Exterior materials were wood walls, wood windows and <br />wood door components. Interior materials were drywall and plaster walls. Floors <br />consisted of vinyl, tile and carpet. <br />For clarification, Section 3 contains a floor plan of the Residence_ <br />3. X -RAY FLUORESCENCE ANALYTICAL METHODOLOGIES <br />Our inspector used a portable XRF LBP Spectrum Analyzer manufactured by Radiation <br />Monitoring Devices ( "RMD ") to test for LBP. Our RMD serial number was 1043 and the <br />age of the radioactive source was nine months. <br />The LBP analyzer was equipped with 12 -mCi cobalt 57 sealed radioactive source. LTE <br />calibrated the XRF pursuant to the manufacturer's specifications and regularly verified <br />XRF readings against pre determined lead samples produced by the National Institute of <br />Standards and Testing (NISI). All of these quality control measures produce a 95% <br />confidence level that our XRF readings accurately reflect the actual level of lead in the <br />tested surfaces. <br />4. AAS / BULK PAINT CHIP SAMPLING METHODOLOGIES <br />For confirmatory testing and compliance with CAL /OSHA regulation Title 8 California <br />Code Regulations Section 1532.1, LTE took five (5) paint chip samples. The samples <br />were analyzed by atomic absorption spectrometry ( "AAS ") testing. The results are <br />attached hereto in Section 2. Per Cal OSHA, 600 ppm is considered dangerous for lead <br />based paint. <br />LABORATORY <br />Ameri Sci analyzed the paint chip samples using atomic absorption spectrometry ('AAS "). <br />It is accredited by both the American Industrial hygiene Association (AIIJA) and <br />participates in their ELLPAT testing program for lead. in addition, it is accredited by the <br />National Institute of Standards and Technology (KIST). <br />19F -73 <br />
