Asbestos is a naturally occurring mineral that has been mined and used in thousands of products since the time of the Ancient Greeks. Due to the strength of the asbestos fibers and their ability to withstand heat, asbestos has been used in many building products.
In the United States after World War II, many of the building products used to build millions of homes, schools and commercial buildings contained asbestos. These products could be found from the roof (roof shingles and mastics) to the basement ( cooling and heating systems and pipes) and everywhere in between.
The laboratory at ATEL is accredited by NVLAP (National Voluntary Laboratory Accreditation Program) and follows all applicable Federal, State and local regulations that cover asbestos analysis of bulk and air samples. ATEL utilizes Phase Contrast Microscopy (PCM) for air sample analysis and Polarized Light Microscopy (PLM) for bulk sample analysis.
