Asbestos is a small mineral fiber that was added to many common household building materials to provide strength, heat insulation or fire proofing. Medical studies have shown an association between exposure to asbestos and various respiratory diseases including asbestosis, mesothelioma (cancer associated with the lining of the lungs) and cancer. The primary exposure route is through inhalation and direct contact of the asbestos fibers with the lung tissue.

Asbestos became a popular commercial building product because it is noncombustible, resistant to corrosion, has a high strength and low electrical and thermal conductivity. Since the 1900’s asbestos fibers have been mixed with various binding materials to create an estimated 3,000 different commercial products. The amount of asbestos contained in these products ranges from 1 to 100 percent.


One Source Environmental will inspect and test for asbestos in your home, apartment, workplace, or commercial property. If you think you may have an asbestos problem, are considering renovations, or are buying or selling a property please contact us to schedule an asbestos inspection. A visual inspection in conjunction with bulk sampling of suspected asbestos containing materials (ACM) is done to determine if there is asbestos present within the property. A certified asbestos inspector will examine all areas for suspected asbestos containing building materials. The bulk samples are then sent to an approved laboratory for microscopic analysis to determine the type and amount of asbestos present in the samples.

Design services (creating remediation plans)

Upon determination of asbestos containing materials (ACM) within a property, One Source Environmental will create a site specific remediation plan for your property. We will design the asbestos abatement project with an emphasis on cost effectiveness and safety. If you plan to renovate or demolish your building and Asbestos is present, then a plan for controlling the ACM must be developed. Our asbestos abatement design services will identify and define the materials needing special handling and disposal and how to manage them during construction. Asbestos containing components that can remain in place and do not need to be disturbed will be clearly identified. Our design will provide you with an accurate cost estimate for abatement, comprehensive plans and specifications. These documents will limit your liability and allow you to competitively bid the work among several contractors. You will then obtain the best price and eliminate construction period change orders at the same time.

Project management & monitoring services (overseeing abatement by other companies)

One Source Environmental will manage your asbestos abatement project by overseeing all aspects of the project to ensure that the contractor is working in accordance with the site specific remediation plans. We are committed to a high standard of care, thereby reducing the risk to the contractors and building occupants. One Source Environmental employs certified project monitors to ensure all asbestos abatement efforts are performed safely and in accordance with all Federal, State and local regulations governing lead-based paint remediation work.

Risk assessment

One Source Environmental provides a more extensive and thorough survey of asbestos hazards through a Risk Assessment. An asbestos risk assessment includes the inspection/assessment of suspected asbestos containing materials (ACM) deteriorated and intact surface areas and any other possible risk areas.

Additionally, an Asbestos Risk Assessment Report identifies any ACM that may pose a hazard to the environment and more importantly to occupants. The asbestos risk assessment report also outlines and offers risk mitigation (management of asbestos risks) and abatement alternatives for any asbestos risks that may be present.

Clearance exams

Clearance exams are conducted following asbestos abatement activities to determine that the project is complete and that no asbestos hazards exist in the dwelling unit or worksite. The clearance process includes a visual assessment and collection and analysis of environmental samples.

Expert witness services

One Source Environmental has several Certified Industrial Hygienists (CIH) on staff to assist our clients with court proceedings related to asbestos exposure. Our senior staff has provided expert testimony in numerous litigations, providing testimony, written reports and laboratory analysis.

Awareness training

One Source Environmental will provide your employees with asbestos awareness training that will enable them to avoid exposure to asbestos within the indoor environment. Awareness training is essential for those with employees likely to be exposed to asbestos within the indoor environment.

Employee exposure monitoring

Employee exposure monitoring in addition to awareness training is essential for those with employees likely to be exposed to asbestos within the context of their work. One Source Environmental will monitor employees in the field using personal air pumps and field evaluation techniques to ensure employee safety with regard to asbestos exposure.

Air, dust & bulk lab analysis

One Source Environmental utilizes methods and protocols of the Environmental Protection Agency (EPA), American Public Health Association (APHA), National Institute of Standards and Technology (NIST), National Voluntary Laboratory Accreditation Program (NVLAP), National Environmental Laboratory Accreditation Program (NELAP), American Industrial Hygiene Association (AIHA), National Institute for Occupational Safety and Health (NIOSH), American Society for Testing and Materials (ASTM), United States Department of Agriculture (USDA), Food and Drug Administration (FDA), and various other applicable Federal, State, and Local programs, guidelines, and regulations.

Phase Contrast Microscopy (PCM) is widely used to measure fiber concentrations of air samples.  This is routinely done at asbestos abatement sites and can be applied for environmental monitoring, personnel monitoring, and clearance testing for minor abatement projects.

Transmission Electron Microscopy (TEM) represents the most sophisticated technology available for characterizing asbestos minerals.  This technique is now the standard for most airborne investigations including post abatement clearance testing as well as diagnostic and environmental monitoring activities.

Polarized Light Microscopy (PLM) is the technique most often employed for the analysis of bulk building materials.  The light microscopy technique utilizes the unique features of polarized light to observe mineral specific optical properties.  In this manner, PLM can differentiate asbestos from non-asbestos fibers and further classify the various species that compose the asbestos mineral family.  Moreover, the technique records the identity of the non-asbestos fibrous component of each bulk building material sample.
