We work with regulated, hazardous materials and conditions


Asbestos is a natural mineral found in many products. Asbestos-containing materials within a structure are identified and classified as surfacing material, thermal system insulation or miscellaneous materials. Surfacing materials are those which are either spray-applied or troweled-on for acoustical, decorative, or fireproofing purposes. Thermal system insulation (TSI) is insulation used to inhibit heat transfer or to prevent condensation on pipes, boilers, tanks, ducts and various other components. Miscellaneous materials include all other building components not included in the above categories such as floor tile, ceiling tile, roofing felt, cementitious materials, wallboard systems and products such as caulking, mastics and putties.


Respirable dust sampling uses a cyclone to separate and capture those particles in the size range which would be deposited in the gas exchange region of the lung. Particles too large to be inhaled are collected in a grit pot in the cyclone. The respirable fraction is captured on a pre-weighed PVC filter for gravimetric analysis.

Lead in Drinking water

Lead in drinking water most often comes from a buildings plumbing system. Lead is present in solder, brass fixtures, and lead or galvanized pipes can leach into water standing tin the plumbing system. The amount of lead that leaches into drinking water, if any , depends on how corrosive the water is and the materials used to construct the plumbing system. If absorbed into the body, lead can damage the brain and other vital organs.

Lead-Based Paint

Lead is a toxic metal used in a variety of products and materials, including paint. Small particles of lead can mix with dirt and household dust when lead-based paint starts to deteriorate. If absorbed into the body, lead can damage the brain and other vital organs. Children may unknowingly poison themselves by eating chips of peeling or flaking lead-based paint or simply by playing in contaminated soil. Some symptoms of lead poisoning are headaches, stomach aches, nausea, tiredness and irritability.


Laboratory Services

The analysis of suspect materials for the presence of hazardous substances (i.e., asbestos, lead and mold).



Mold spores are commonly found in the air inside homes and on most surfaces, including clothes, walls and furniture. Most spores found indoors originate from outdoor sources. Problems occur with mold growth, which is usually caused by moisture intrusion (e.g., failure in building enevlope, leaking pipe, etc.).


Indoor Air Quality

The definition of good indoor air quality: Introduction and distribution of adequate ventilation air, control of airborne contaminants, and maintenance of acceptable temperature and relative humidity. However, indoor air quality is not a simple, easily defined concept. It is a constantly changing interaction of complex factors. Indoor air quality is a major concern to businesses, building managers, tenants, and employees because it can impact the health, comfort, well-being, and productivity of building occupants. Most Americans spend up to 90% of their time indoors and many spend most of their working hours in an office environment.
