Lead & Asbestos Survey & Risk Assessment
Challenge & Solution
The federal government is privatizing bachelor housing at sites in Virginia. In an effort to recommend opportunities to avoid, minimize, and mitigate potential future environmental impacts associated with the property transfer, the federal government solicited Rhea to perform a Phase 2 Environmental Condition of Property (ECP), which included Asbestos-Containing Materials (ACM) Inspections and Lead-Based Paint (LBP) Inspections and Risk Assessments.
The ECP survey was performed in accordance with 24 Code of Federal Regulations Parts 50 and 58, as well as the project Sampling Plan and Health and Safety Plan, which were prepared by Rhea and accepted by the federal government prior to the commencement of field work.
Project Description & Highlights
Rhea obtained information from a variety of sources, which provided site historical uses, records of previous/existing environmental problems (i.e., presence of mold, radon, and/or wetlands) on or near the properties, and the present conditions of the properties and surrounding properties. Site inspections were performed where samples of paint, dust, floor tiles, ductwork and pipe insulation, ceiling tile, and other materials which might contain asbestos or lead, were collected and analyzed. Property walkovers were also performed to determine if any hazardous materials or conditions exist on the subject properties prior to privatization.
Areas of Concern were identified based on the background investigations, visual inspections/property walkovers, interviews, and laboratory and x-ray fluorescence (XRF) testing results. The results of the ECP survey were provided in three separate ECP Survey Reports and were submitted to the client.
During the LBP Investigation, a portable XRF analyzer was used to perform a real-time scan of the painted surfaces. This instrument provided immediate results and useful information, including lead content and depth of lead contamination in the paint and completely eliminated paint-chip sampling.
