We are hands-on consultants / contractors and perform most projects turn-key. With our resources, equipment and experience, we have successfully completed a broad range of environmental projects with a minimal use of sub contractors, which helps to control costs. Our experience in characterization, waste management, and remediation has allowed us to manage and complete countless site investigations, tank removals, and remediation projects for clients throughout the United States. L & R has performed remediation of soil, groundwater, and structures including decommissioning and closure of waste management areas regulated under US NRC, RCRA, CERCLA, UST, and TSCA.

Our goal is to form long-term working relationships with our clients by demonstrating a comprehensive understanding of their unique environmental needs and by assisting them in achieving compliance with regulations influencing their operations.

Asbestos is a group of naturally occurring fibrous silicate minerals.  The six forms of asbestos are: Actinolite, Amosite, Anthophyllite, Chrysotile, Crocidolite, and Tremolite.  Asbestos fibers are strong and flexible enough to be spun and woven and are heat and chemical resistant, making them useful for many industrial purposes.  Due to these properties asbestos has been used in over 3,000 different products.

Asbestos is most commonly found in older homes and buildings in the following materials:

  • pipe and furnace insulation materials
  • roofing materials
  • exterior siding
  • wallboard and textures/joint compound
  • textured paints and other coating materials
  • flooring materials and adhesives

While many asbestos containing materials have been banned in the United States, asbestos continues to be used today in building material construction making it necessary to test modern building materials.

The following are some of the materials in which the use of asbestos is not banned and may be used in new construction today:

  • Vinyl floor tile
  • Roofing felt
  • Roof coatings
  • Non-roofing coatings
  • Millboard
  • Cement shingle
  • Cement pipe
  • Cement corrugated sheet
  • Cement flat sheet
  • Pipeline wrap
  • Automatic transmission components
  • Clutch facings
  • Friction materials
  • Disk brake pads
  • Drum brake linings
  • Brake blocks
  • Gaskets
  • Clothing

If asbestos-containing materials are disturbed by cutting, sanding or other remodeling activities, asbestos fibers can be released to the air where they can become an inhalation hazard.  To be a significant health concern, asbestos fibers must be inhaled at high concentrations over an extended timeframe.  Significant exposure to asbestos increases the risk of asbestosis or mesothelioma.

Asbestosis is scarring of the lung tissue.  Asbestosis restricts breathing leading to decreased lung volume and increased resistance in the airways. It is a slowly progressive disease with a latency period of 15 to 30 years.

 Mesothelioma is a cancer of the pleural lining and is considered to be exclusively related to asbestos exposure. By the time it is diagnosed, it is almost always fatal. Similar to other asbestos related diseases, mesothelioma has a longer latency period of 30 to 40 years.

Asbestos can be positively identified in air, bulk, and/or dust samples only by trained analysts using specialized microscopes.  L&R has trained and experienced staff along with the necessary equipment and instrumentation to provide quality asbestos analysis of air, bulk, and/or dust samples.  We offer various methodologies (NIOSH, EPA, OSHA, ASTM, etc.) utilizing Phase Contrast Microscopy (PCM) and Polarized Light Microscopy (PLM).
