Consider this scenario: a family in Evans moves into a newly built home and within the first week, two household members develop persistent headaches and one child complains of a sore throat that does not resolve. They check for mold: nothing visible. Radon test: normal. They assume the cause is seasonal allergies. Two months later, after symptoms do not improve, they arrange an indoor air quality test. The results show formaldehyde levels three times higher than the EPA reference concentration and elevated total VOC levels traced to new cabinetry, flooring adhesive, and interior paint.
Mold and radon receive most of the attention in indoor air quality discussions, but they are not the only pollutants worth understanding. Volatile organic compounds, particulate matter, and formaldehyde are present in virtually every home, and their sources are things most people bring inside intentionally.
Volatile Organic Compounds (VOCs)
VOCs are organic chemicals that evaporate at room temperature, releasing gases into the air. The term covers a broad category of compounds, some relatively harmless and others with well-documented health effects.
Where VOCs Come From
The EPA identifies thousands of products that emit VOCs. In a typical home, the most significant sources include:
- Paints and finishes: Fresh paint off-gasses for days to weeks. Even low-VOC paints emit some compounds during and after application.
- New furniture and cabinetry: Pressed wood products including particleboard, MDF, and plywood use urea-formaldehyde resins that emit formaldehyde and other VOCs for months or years.
- Flooring: New carpet, vinyl flooring, laminate, and the adhesives used to install them are significant VOC sources during and after installation.
- Cleaning products: Many household cleaners, disinfectants, and air fresheners contain VOCs. Fragrance compounds in these products are VOCs by definition.
- Stored chemicals: Gasoline, paint thinner, pesticides, and solvents stored in attached garages can off-gas into the home through shared walls, gaps in the garage connection, and HVAC intakes.
Health Effects
Short-term exposure to elevated VOCs can cause eye, nose, and throat irritation, headaches, dizziness, and nausea. Long-term exposure to certain VOCs including benzene, formaldehyde, and perchloroethylene is associated with increased cancer risk. The specific health effects depend on the compound, concentration, and duration of exposure. The EPA notes that indoor VOC concentrations are consistently higher than outdoor levels, typically by a factor of two to ten.
Formaldehyde
Formaldehyde deserves separate attention because it is one of the most common and well-studied indoor air pollutants. It is classified as a known human carcinogen by the International Agency for Research on Cancer and as a probable human carcinogen by the EPA.
Primary Sources
The largest sources of formaldehyde in residential settings are pressed wood products used in cabinetry, subflooring, and furniture, which rely on urea-formaldehyde adhesives. Other sources include wrinkle-resistant fabrics, some paints and coatings, and combustion from gas stoves, fireplaces, and tobacco smoke. New homes and recently renovated spaces have higher formaldehyde concentrations because off-gassing rates are highest when materials are new and decline gradually over time.
Exposure Thresholds
The EPA chronic reference concentration for formaldehyde is 0.008 ppm (parts per million). In new construction, formaldehyde levels above 0.1 ppm are not uncommon, particularly in spaces with new cabinetry, flooring, or furniture. At these levels, sensitive individuals and children experience irritation symptoms. At higher concentrations, the effects extend to more severe respiratory and neurological responses.
Particulate Matter
Particulate matter (PM) refers to solid or liquid particles suspended in the air. PM10 (particles 10 micrometers or smaller) can reach the upper respiratory tract and cause irritation. PM2.5 (particles 2.5 micrometers or smaller, roughly 30 times thinner than a human hair) penetrates deep into the lungs and can enter the bloodstream, where it is associated with cardiovascular and respiratory effects. The CDC’s National Institute for Occupational Safety and Health recognizes fine particulates as a significant indoor health concern.
Common Indoor Sources
- Cooking: Gas stoves and frying produce PM2.5 at levels that can briefly exceed outdoor air quality standards. Running exhaust fans during cooking is the most direct control measure.
- HVAC systems: Filters that are overdue for replacement or improperly sized allow particles to recirculate through the home continuously.
- Mold: Mold colonies release spores, which are airborne particles, continuously. Elevated PM indoors can indicate mold activity even before visible growth appears.
- Outdoor infiltration: In the CSRA, spring pollen season and regional wildfire smoke are seasonal contributors to indoor particulate levels through normal air infiltration.
When to Test for VOCs, Formaldehyde, and Particulates
Professional indoor air quality testing for these pollutants is most valuable in the following situations:
- After moving into a new home or a recently renovated space
- When household members experience persistent symptoms with no clear cause, particularly symptoms that improve when away from home
- After installing new carpet, flooring, cabinetry, or furniture in a poorly ventilated space
- In homes with attached garages, where VOC migration from stored chemicals is a documented pathway
- When a child, elderly person, or immunocompromised individual with respiratory sensitivities occupies the home
Testing identifies which pollutants are elevated and at what concentrations, which in turn points toward specific sources and appropriate solutions. Without testing, interventions such as opening windows, running air purifiers, or replacing HVAC filters may or may not address the actual problem.
Indoor Air Quality Testing in the Augusta Region
EnviroPro 360 provides indoor air quality testing for VOCs, formaldehyde, particulate matter, and other pollutants in homes, rental properties, and commercial spaces throughout Augusta, Evans, Martinez, Grovetown, North Augusta, Aiken, and the greater CSRA. Testing follows EPA and industry protocols, with samples analyzed by accredited laboratories. Results are delivered in a written report that identifies findings, compares them to established reference levels, and supports any follow-up decisions the household or building owner needs to make.
If a new home, a recent renovation, or persistent symptoms suggest that indoor air quality may be a concern, professional testing provides the data needed to confirm or rule out a problem. To schedule indoor air quality testing in the Augusta or Aiken area, contact EnviroPro 360.
