Atch 22 - 02 83 33.13.1 Lead Based Paint Survey 07-2006.pdf

This is a Lead-Based Paint (LBP) Survey Report documenting environmental testing and analysis of exterior building components at Jonathan M. Wainwright Memorial VA Medical Center in Walla Walla, Washington.

MCS Environmental, Inc. contracted by Zeck Butler Architects conducted a limited LBP survey of exterior coated building components on Buildings 68, 69, 77, 78, T-1, T-2, and a covered walkway connecting Buildings 68 to 77. Certified EPA/Washington State Lead Risk Assessor Samuel W. Bailey Jr. performed field surveys on July 12, 2006 with a follow-up visit on July 26, 2006. The survey employed X-ray fluorescence (XRF) spectroscopy with a Scitec Endaq analyzer, collecting 336 XRF assays to identify paint films with lead concentrations of 1.0 mg/cm² or greater as regulated LBPs. MCS also collected 19 bulk paint scrape samples from selected components with inconclusive or negative XRF results, submitting samples to EMSL Analytical, Inc. for EPA method SW846-1311/7420 analysis.

The survey identified multiple exterior components with lead-based paint hazards across all buildings, including concrete and CMU foundation walls, metal vents and piping, wood soffits and fascia moldings, window sashes, storm screens, wood railings, and roof cupules. Six bulk paint chip samples exceeded the Federal 0.5 percent lead-by-weight threshold, with concentrations ranging from 0.84 to 28.00 percent by weight. The report notes that components in satisfactory condition do not currently constitute hazards but could become problematic if paint deteriorates or is disturbed. Prohibited interim control methods include uncontained abrasive or water blasting, power sanding, or open flame burning. If removal and disposal of LBP-coated components is required, toxic characterization leaching procedure (TCLP) sampling must be conducted to determine appropriate waste classification and disposal requirements.
