Southern California Indoor Air Quality Testing

Southern California Indoor Air Quality Testing

Indoor air quality is a challenge. It can affect employee productivity and health. 

Yet, complaints can be non-specific and sometimes similar to those from colds, flu, stress and allergies.  It can initially be difficult to determine if problems are caused by sources or conditions in the building, and what can be done to remedy the complaints.

The good news is that a common cause of complaints is often a simple lack of maintenance.  Every response should start with an inspection of the air handler unit(s) servicing the area of complaint.  Sometimes, pre- and inner-filters of the building’s heating, ventilation and air-conditioning (HVAC) system have exceeded their useful life.  Putting HVAC maintenance and inspection on  a firm schedule is an easy and inexpensive fix.  The HVAC inspection can be performed either by Ellis or (even better) by the building’s professional maintenance staff.

Proper initial testing is also an easy and inexpensive starting point.  This will often include placing a “Q-Trak” monitor in the area of complaint. A Q-trak measures and records concentrations and trends in carbon monoxide, carbon dioxide (CO2), temperature and relative humidity.  CO2 concentrations of 1,000 ppm or more produce complaints of stuffy air, itchy eyes, etc.  As with most indoor air quality issues, elevated CO2 levels are most often traced to problems with the building's HVAC system.

Many times the investigator must consider all the factors that relate to indoor air quality to identify possible contaminants and stressors which could be responsible for the reported complaints and effects. This requires a process of identifying and eliminating numerous potential contaminants, sources and other factors in the hope that the true causal factor will eventually be identified. It requires time and patience on the part of both the building owner and it occupants.

  1.   airborne mold
  2.   surface mold
  3.   allergens
  4.   ultrafine dust particles emitted from printers and copiers
  5.   respirable and nuisance dust, usually from nearby construction activities
  6.   hydrogen sulfide (sewer smell)
  7.   fecal contamination (E. coli & Enterococcus), most often performed following a sewage leak and cleanup
  8.   airborne asbestos
  9.   bulk asbestos
  10.   airborne lead
  11.   damaged lead paint
  12.   volatile organic compounds (VOCs), emitted from chemical processes - SUMMA-type canister or TEDLAR bags
  13.   formaldehyde, a contaminant associated with urethane insulation, preservatives and embalming processes
  14.   propane
  15.   legionella
  16.   other contaminants, depending on site specific needs

Depending on the targeted contaminant, Ellis will partner with CalScience Laboratories, EMSL, LA Testing, Silliker Labs, and other local and national AIHA- and NVLAP-accredited laboratories.
