More and more people are being affected adversely by poor Indoor Air Quality (IAQ). The professional staff of Nauset Environmental Services, Inc. (NES) and its original office in St. Louis, Environmental Solutions, Inc., have responded by developing and offering IAQ services since the early 1980s. They have kept current on developments and issues in the indoor air arena, including receiving certificates from training on “Orientation to Indoor Air Quality”, “Hands-On Measurement & Diagnostics: Evaluating the Indoor Environment,” “Investigating, Sampling, Identifying and Assessing Biological and Microbiological Contamination in the Indoor Environment ,” “How to Identify Construction Defects as the Causative Factor in Mold Growth,” etc.
Our professional staff is led by William M. Vaughan a PhD and Qualified Environmental Professional (QEP since 1994) with 40+ years of air quality experience. He and Alex MacLellan have gone through training and separate independent certification by the American Council for Accredited Certification (www.acac.org). Dr. Vaughan is a Council-certified Indoor Environmental Consultant (CIEC #0608032) and Alex is a Council-certified Residential Mold Inspector (CRMI #0604036).
IAQ is a complex area where biological, physical, chemical and even psychological factors can play a role, singly or in a mix. There is no single IAQ parameter to be measured that can tell whether the indoor air is harmful, merely irritating, or acceptable. BEFORE measurements are made or “remediation” is undertaken (often at considerable expense) it is best to carry out an initial inspection/investigation to identify possible problems and focus testing and/or remediation on the potential source areas identified. This activity should NOT be carried out by someone with a conflict of interest who recommends the actual work he would perform.
The following is a list of some of NES’s IAQ services. One or more may be appropriate for a given client’s situation:
- Occupant surveys – diaries of incidents and surrounding conditions
- Site surveys and inspections – examination to develop possible causes (water leaks, ventilation, etc.)
- Problem diagnosis – what needs to be investigated further by sampling or more complex evaluation
- Occupant exposure monitoring if warranted – per OSHA guidelines or other more stringent standards
- Sampling – planning, gathering and analyzing
- Air contaminants –
- Particulates in multiple size ranges
- Air toxic vapors (volatile organic compounds (VOCs), formaldehyde, 40+ compound screening, environmental tobacco smoke (ETS), etc.)
- Carbon monoxide (CO) and carbon dioxide (CO2) as indicators of adequate ventilation
- Bioaerosols (mold, fungi, bacteria, viable organisms, pet dander, dust mites, etc.)
- Asbestos fibers in bulk materials, air or accumulated dust
- Radon (the second leading cause of lung cancer in the U.S.A.)
- Lead in paint and accumulated dust (in conjunction with a MA licensed Lead Inspector)
- Electromagnetic (EMF) surveys
- Air contaminants –
- Remedial recommendations
NES provides customers with environmental consultants with an air quality specialty. The staff is experienced in documenting air quality factors significant for sensitive individuals but well below levels regulated by the Occupational Safety and Health (OSHA) administration. The staff keeps current on trends and recommended sampling approaches by attending specialized workshops and seminars that grant Continuing Education credit (CEUs) (see Credentials tab). After years of activity in the IAQ field they have also developed a network of other professionals who can be contacted for additional insight in solving IAQ problems.
If you think you may have an IAQ problem, the professionals at NES can help you develop the objective information needed to choose an effective corrective action, without a conflict of interest. NES works within your budget to provide the most complete, objective information possible with the goal of having those actions help eliminate the problem.
