Other Services

Indoor Science performs indoor air quality assessments for just about any contaminant or concern.  Besides the services elsewhere described on our site, there are a number of other indoor environmental issues we handle, including:

    Sewer Gas

    We use instruments to detect if sewer gas is coming out of a plumbing fixture, floor drain, or vent stack.  We may even perform peppermint or smoke tests to help identify a source.


    Besides testing for fecal bacteria, and Legionella bacteria, we can test for all other types.  We can perform air samples for total bacteria counts or swab surfaces for specific bacteria such as MRSA.


    If you need to calculate air exchange rates for a building or determine a ventilation rate, Indoor Science can use several different methods including carbon dioxide and tracer gas (sulfur hexafluoride).

    Particulate matter

    • We can monitor airborne particle and dust levels using a laser particle counter or nephelometer.
    • We can identify the source of particles or dust using advanced laboratory-based methods.
    • We can monitor your workplace for respirable and total dust for OSHA compliance.


    If there are dark stains on the wall, we can perform an assessment to determine the source.  It may be from a combustion appliance, candles, or mold.

    Outdoor Air pollution

    Although most of our instruments are not made for the harsh conditions outdoors, we can perform spot measurements of the outdoor air quality.  We can detect combustion by-products like nitrogen oxides and carbon monoxide.


    Ozone can be released by some equipment found in an office, home, or factory.  For example, some photocopiers can give off ozone.  Ozone is a lung irritant and can exacerbate asthma.

    If you have any of the above concerns, or even ones not listed, please contact us at (312) 920-9393 for a free phone consultation.
