Indoor Air Quality
The EPA lists Indoor Air Quality in its top ten environmental concerns.

Our assessment protocol determines the extent to which there are indoor air quality problems in buildings, to determine their source and cause, contaminant pathways, and to recommend appropriate remedial measures as warranted. Weir Environmental, LLC utilizes the most efficient and sensitive state-of-the-art instrumentation available in the conduct of indoor air quality assessments to assure accuracy of results and rapid turnaround times.

We perform on-site sampling to determine the nature and the source of indoor air contaminants and/or physical characteristics, if any, that are responsible for specific symptoms and complaints. We test for carbon monoxide, carbon dioxide, formaldehyde, 4-phenylcyclohexane, volatile organic compounds, and radon. We also survey physical parameters such as temperature, humidity, illumination, sound pressure levels, air exchange, and ventilation rates. Biological testing includes total colony counts and species identification for bacteria and fungi and non-viable spore counts.

Upon completion of the IAQ analysis, we compare them with applicable regulatory and industry standards, guidelines and criteria in order to provide a detailed report containing the levels of concern. If problems are detected, we also provide recommendation for removal of any contaminants found.

Although there are no current regulations on indoor air quality, guidelines have been developed from governmental agencies and private professional organizations including recommendations from the Environmental Protection Agency (EPA), the American Conference of Governmental Industrial Hygienists (ACGIH), the Occupational Safety and Health Administration (OSHA), and the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE). The ASHRAE Standard, 62-1989, "Ventilation for Acceptable Indoor Air Quality", is universally accepted for assessment of indoor air.
