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.
