Managing air quality is essential in preventing illness and injury and provides a safe environment.


Our professional team of Certified Industrial Hygienists (CIH) or Certified Microbial Consultants (CMC) will implement air quality inspections, monitoring, assessments and recommendations for corrective actions.

PHASE Associates uses the latest direct-reading instruments and accredited laboratories using government-approved laboratory test methods when collecting samples.

The scope of an IAQ survey typically involves a visual inspection, occupant interviews and sampling of the subject building’s temperature, humidity, carbon dioxide, carbon monoxide and volatile organic compounds (VOCs).

Asbestos, Mold, Legionella, Radon, and Formaldehyde can be dangerous Indoor Air quality hazards and can be harmful to the workplace environment and one’s health.

Our highly trained, board accredited professionals are able to conduct assessments, surveys and recommendations for the following services below.

Asbestos Surveys & Hazard Assessments

An EPA certified AHERA inspector will conduct a visual inspection and collect bulk samples for suspect Asbestos Containing Material (ACM), document, label and assess each ACM .

PHASE Associate’s EPA certified AHERA inspectors are trained in sampling and identifying potential asbestos-containing materials. Asbestos services include surveys, sampling, air monitoring and consulting. All samples collected by PHASE Associates are analyzed by an accredited laboratory, and handled under a strict quality control program to assure the safety of our clients and the integrity of our services.



  • Conduct visual inspection mold growth of the interior structures and ventilation systems.
  • Collect bulk, surface or air samples for further genus or species identification and quantities.
  • Prepare a bio remediation plan based on the visual inspection and sampling result.

Mold, Bacteria & Bioaerosol Investigations

Moisture from dampness or water leaks can cause mold and mildew formation and result in health issues. PHASE Associates offers comprehensive mold and bacteria related services.

PHASE Associates will provide highly trained industrial hygienists, Certified Industrial Hygienists (CIH) or Certified Microbial Consultants (CMC) to conduct the inspections and surveys and who will also provide and recommendations and/or create a bioremediation plan.  Our services extend to both commercial and home clients. We also do pre remediation and post remediation surveys and have worked with insurance companies and remediation companies as a third party contractor.

We can serve New York City and New York State as PHASE Associates obtained a New York State Mold Assessor license. We have qualified NY Mold Assessors who have been licensed by the New York State Department of Labor.

Currently, all of our mold investigations follow the ASTM E 2418-06 guidelines for assessing readily observable mold, as well as determining conditions and physical deficiencies conducive to mold. All recommendations derived from our inspections are in accordance with accepted guidelines determined by the EPA as well as the American Conference of Industrial Hygienists (ACGIH).

Legionella Surveys

Legionella is common in many environments. It has a minimum of 34 species identified. Legionella is the motile aerobic rod-shaped Gram-negative bacterium that thrives in heating and air conditioning systems and even in appliances(i.e. ice machines) that are equipped with water reservoirs and can cause Legionnaires’ disease. L. pneumophila serogroup 1 is the most frequently identified form of the bacterium isolated from patients with Legionnaires’ disease, although other serogroups and subtypes of the bacterium are frequently isolated from water sources.

The diseases produced by Legionella are called legionellosis. More than 34 species of Legionella have been identified, and more than 20 linked with human diseases. L. pneumophila causes the pneumonia known as Legionnaires’ disease and the flu-like Pontiac fever.

Legionella has certain growth requirements that need to be met in order for it to continue to survive and grow. Some of these growth requirements include temperatures above 8 degrees, mass amounts of iron and L Cysteine and biofilm.

According to OSHA, water sources that frequently provide optimal conditions for growth of the organisms include:

  • cooling towers, evaporative condensers, and fluid coolers that use evaporation to reject heat. These include many industrial processes that use water to remove excess heat;
  • domestic hot-water systems with water heaters that operate below 60°C (140°F) and deliver water to taps below 50°C (122°F);
  • humidifiers and decorative fountains that create a water spray and use water at temperatures favorable to growth;
  • spas and whirlpools;
  • dental water lines, which are frequently maintained at temperature above 20°C (68°F) and sometimes as warm as 37°C (98.6°F) for patient comfort; and
  • other sources including stagnant water in fire sprinkler systems and warm water for eye washes and safety showers.

Water stored below 20°C (68°F) is generally not a source for amplified L. pneumophila levels. However, high levels of bacteria have been measured in the water supplying ice machines. The source of amplification in this case was thought to be heat from the condenser coil of the ice maker to the cold water supply. However, no cases of Legionnaires’ disease have been linked to consumption of ice made from contaminated water.


Obtain an overview of all water systems at the building following the OSHA Technical Manual protocols.

1) Conduct a walk-through investigation of the building.

2) Assess the results of the walkthrough investigation to evaluate the next action plan.

3) Recommend control action plans include proper system temperatures, eliminating dead legs.

4) Collect water samples to identify Legionella levels after correction actions are successfully completed.

Radon Surveys

All radon testing is done by our radon professional that holds the highest classification for  Radon Test Professionals, a licensed New Jersey Radon Measurement Specialist. Our professional has conducted countless radon surveys for child care centers, homes and commercial buildings.

PHASE Associates has a niche in conducting radon surveys for child care centers. Every five years, child care centers need to conduct a radon survey in order to renew their license. By law, only the building owner or a NJ Certified radon business can conduct the radon survey for child care centers.

The process is to collect, deploy and pick up the measurement radon devices. Each radon canister will be left for four days. No windows or doors can be left open during that period of time unless for normal exit and entry.
