Lead Testing

Lead dust, if ingested or inhaled, can cause serious health problems, including blood disorders, muscle weakness and mental retardation. OSHA requires that lead dust levels be monitored during construction, renovation and demolition projects to protect workers and the public. The demolition waste generated from a worksite must also be characterized before it can be accepted by a landfill.

ADE can assist owners to meet the requirements of the federal, state, and local regulations regarding repair, remodeling, and demolition projects where lead paint is involved. ADE can perform a lead-containing material screening assessment for representative paints and coatings on site. The lead assessment included the collection of representative paint chip samples from the various substrate surfaces. Samples collected will be analyzed using flame atomic absorption spectroscopy method.

Waste Disposal

The Washington State Department of Ecology currently requires that renovation/demolition wastes be characterized under the provisions of Identification, Sampling, and Testing Demolition Wastes (WAC 173-303). Identification, Sampling, and Testing Demolition Wastes is the process used to find out if a waste is a regulated dangerous waste. Designation includes determining if any waste from building construction or demolition is a dangerous waste.

Dangerous Waste testing regulations do not regulate how many waste samples to take or where to take them as long as one representative sample is done of each waste to be tested. A representative sample is defined in the Dangerous Waste Regulations WAC 173-303-040.

According to Washington State Ecology, lead based paint is the most common problem encountered in older buildings. Buildings constructed prior to 1960 used paint with high lead content, and lead continued to be used in latex paint up to 1978. Older buildings intended for demolition should be sampled and tested for lead Ecology's Suggested Sampling Plans for Building Debris Disposal.
