Indoor Air Quality Testing

VOC Testing: Science-Based Chemical Air Quality Investigation

Persistent odors, unexplained symptoms, or recent renovations? ESG uses accredited laboratory analysis to identify the specific chemical compounds in your indoor air and trace them back to their source. We test. We never sell remediation.

From Unexplained Odors to Chemical Identification

VOCs are invisible and cannot be identified by smell alone. Laboratory analysis is the only way to know which specific compounds are present and whether they originate from a normal building source or something more serious.

Before Testing

Chemical Odors, No Identified Source

Occupants notice persistent smells or experience symptoms like headaches, dizziness, or respiratory irritation. Without testing, there is no way to know what compounds are present or where they originate.

Specific Compounds Identified, Source Traced

A written report identifies the exact chemical compounds present, their concentrations, likely sources, and clear recommendations, giving building owners and occupants actionable information.

A Complete VOC Investigation, Not Just a Sample

ESG's VOC assessments combine building history review, environmental measurements, specialized air sampling, and accredited laboratory analysis to identify not just what chemicals are present, but where they are coming from.

Why ESG

Independent Testing: No Products to Sell, No Bias

Environmental Solutions Group has been performing independent environmental testing and consulting since 2002, more than 23 years. Our VOC assessments are driven by science and building investigation, not by a sales agenda for air purifiers, filters, or treatment products.

Because we never sell remediation services or air quality products, our recommendations are genuinely independent. If elevated VOCs are identified, we tell you what the likely source is and what practical steps can address it, without any upsell.

Our certified professionals (CIEC, CMR, CIH) have the training and equipment to investigate chemical air quality concerns in homes, offices, schools, healthcare facilities, and industrial settings.

How VOC Testing Works

A structured four-step investigation that moves from your initial concern to lab-verified chemical identification and clear guidance.

Lab Analysis

Samples are analyzed by accredited environmental laboratories, identifying every individual VOC compound present, its concentration, and total VOC levels: data that cannot be obtained through odor alone.

Clear Report

You receive a detailed written report with lab findings, source analysis, and practical recommendations. An ESG professional is available to review every result with you.

Professional Testing vs. Guesswork

ESG VOC Testing: Laboratory-Verified

Professional VOC testing identifies the exact chemical compounds in your air, their concentrations, and their likely sources, providing the objective data needed to make informed decisions.

  • Identifies specific VOC compounds, not just "chemical odor"
  • Traces compounds to likely source categories (cleaning products, building materials, HVAC, etc.)
  • Provides independent, unbiased recommendations with no products to sell
  • Defensible data for workplace complaints, insurance, or legal proceedings

Consumer Monitors & Air "Purifiers": Their Limits

Consumer air quality monitors and air purifiers do not identify which specific compounds are present, cannot trace contamination to a source, and may mask problems rather than solve them.

  • Report only generic "VOC" readings with no compound identification
  • Cannot determine whether compounds originate from normal use or contamination
  • Do not provide documentation for workplace or legal purposes
  • Treating symptoms without identifying the source leaves the problem unresolved

Independent Answers You Can Rely On

VOC Testing: Frequently Asked Questions

What are VOCs and why do they matter indoors?

Volatile Organic Compounds (VOCs) are carbon-based chemicals that easily evaporate into the air at room temperature. Because buildings trap air, VOCs from cleaning products, building materials, furnishings, paints, and solvents can accumulate to concentrations that cause noticeable odors or, at higher levels, occupant symptoms such as headaches, dizziness, or respiratory irritation.

What are common signs that I may need VOC testing?

The most common triggers are persistent chemical or solvent-like odors that cannot be traced to an obvious source, occupant symptoms that improve when people leave the building and return when they re-enter, recent renovations or new material installations (flooring, paint, cabinets), and indoor air quality complaints in offices, schools, or healthcare facilities.

Can VOC testing identify where the chemicals are coming from?

Lab analysis identifies which specific chemical compounds are present. By combining that data with the building walkthrough, occupant interview, and environmental measurements, ESG can often narrow down the likely source category, whether that is cleaning products, off-gassing building materials, HVAC contamination, stored chemicals, or an external industrial source.

Is VOC testing the same as measuring air quality with a consumer monitor?

No. Consumer monitors report a generic "total VOC" number that cannot identify which compounds are present or at what levels. Accredited laboratory analysis identifies individual chemical compounds with precision. This is the only approach that provides scientifically defensible data for source investigation, workplace complaints, insurance, or legal purposes.

Do new buildings or renovations need VOC testing?

New construction and recent renovations are a common reason for VOC testing. Many building materials, including flooring adhesives, paints, sealants, cabinetry, and furniture, release VOCs during installation and curing. Testing can confirm whether materials are affecting air quality and inform ventilation strategies or occupancy timing decisions.

Does ESG sell air purifiers or remediation products after testing?

No. ESG is an independent testing and consulting firm only. We do not sell air purifiers, filters, or any treatment products. Our recommendations are entirely science-driven and focused on identifying and removing the source of contamination (improving ventilation, adjusting cleaning practices, or isolating chemical sources), not on selling equipment.
