Lead Paint Inspection

Client: Private company, Kennett Square PA Description: Brownfield Science & Technology, Inc. (BSTI) provided technical lead assessment

services to the owner of a structure undergoing renovation. The structure was built in the late

18th century and required substantial renovation prior to occupation. Due to the age of the

structure, lead-based paint (LBP) was presumed to be present.

A lead paint inspection is a surface-by-surface investigation to determine whether there is

lead-based paint in a structure or child-occupied facility. Inspections can be legally performed

only by certified inspectors or risk assessors.

BSTI’s objectives where to help our client to understand the level of screening appropriate and

to provide documentation to guide the on-scene construction workers. After some careful

consideration, BSTI’s client opted for a modified lead-based paint inspection that incorporated

a combination of field screening and sample collection.

During the inspection, components in each room as well as some exterior components were

surveyed for the presence of LBP using a portable X-ray fluorescence (XRF) spectrum analyzer.

A total of 136 XRF paint readings were taken and catalogued using in-system data capture.

After testing with the XRF was completed, the inspector collected dust “wipe” samples to

determine the quantity of lead in the dust throughout the structure. The results of the XRF

testing confirmed that lead-based paint was present on both interior and exterior surfaces.

The dust wipe samples also showed that lead dust levels where present above EPA/HUD

guidelines.

As a result of the modified approach, the client was able to prioritize and scale mitigation activities to assure protectiveness of human health while maintaining their budget. BSTI was able to define the remaining, less significant risk factors within a context that was understood and therefore manageable to our client. Our client subsequently moved forward with their intended plans for the property.

Objective:

Provide actionable data mid-construction

to inform and prioritize lead-based paint

mitigation measures.
