Contents Testing

Assessment of personal items (furniture, clothing,, etc.) for mold contamination to determine if cleaning, disposal, or specialized treatment is needed.

Indoor Allergen Sampling

Dust sampling to detect common indoor allergens such as mold spores, dust mites, pet dander, and pollen—useful in evaluating occupant exposure and indoor environmental quality.

Occupant Health Complaints

Environmental assessments in response to symptoms like respiratory issues, fatigue, or headaches, often linked to mold, allergens, or poor indoor air quality.

Lead

Lead is a toxic metal once commonly used in paint, plumbing, and other building materials. Exposure—especially through dust, soil, or drinking water—can harm the brain and nervous system, particularly in children and pregnant women.

XRF Lead-Based Paint Inspections
Fast, non-destructive testing using X-ray fluorescence (XRF) to detect lead-based paint in residential, commercial, and institutional buildings—performed in compliance with HUD and EPA standards.

Lead Dust Clearance Testing
Post-abatement or post-renovation dust wipe sampling to verify safe reoccupancy and compliance with HUD/EPA clearance levels.

Lead in Soil Analysis
Soil sampling and analysis to assess potential lead contamination around buildings, playgrounds, and bare yard areas—often required for child-occupied facilities or pre-construction due diligence.

Lead-in-Water Testing for Licensed Child Care Centers (CCCs)
Compliance sampling of potable water outlets in licensed childcare centers as required by California regulations. Includes coordination with ELAP-accredited labs and detailed reporting.

Indoor Air Quality

Assessment and testing of indoor environments to detect mold growth, moisture intrusion, and related health risks—helping ensure safe, dry, and healthy spaces.

Initial Mold Assessments

Thorough inspections to identify visible mold, moisture sources, and hidden growth.Includes air or surface sampling and recommendations.

Post-Remediation Mold Clearances

Verification testing to confirm remediation was successful and the space is safe for re-occupancy. Includes visual inspection and air sampling as needed.

Contents Testing

Occupant Health Complaints

Environmental assessments in response to symptoms like respiratory issues, fatigue, or headaches, often linked to mold, allergens, or poor indoor air quality.

Volatile Organic Compounds

Volatile Organic Compounds (VOCs) are airborne chemicals emitted from sources like paints, cleaners, adhesives, building materials, and personal care products. They can affect indoor air quality and pose significant health risks, ranging from irritation and headaches to serious conditions; some VOCs are carcinogenic.

Comprehensive VOC Air Sampling with EPA Method TO-15

We perform air sampling for 74 VOCs using SUMMA canisters analyzed with EPA’s TO-15 method. This widely recognizedadvanced technique detects harmful chemicals from sources such as fossil fuels, smoking, paints, adhesives, cleaning products, building materials, personal care items, and vehicle exhaust. Results are compared to health-based exposure limits (Cal/OSHA, EPA, CA OEHHA) to assess odors, indoor air quality, and potential health risks. This service is ideal for residential, commercial, healthcare, and industrial settings.

The process involves collecting air samples in a stainless steel canister, which is sealed and sent to a laboratory for analysis. Using gas chromatography-mass spectrometry (GC/MS), the lab separates and identifies individual VOCs, quantifying each compound by comparison to calibrated standards.

Bacteria

Bacteria are microscopic organisms found throughout our environment—some harmless, others harmful. After black water (Category 3) events involving sewage or floodwaters, dangerous bacteria like E. coli and fecal coliforms may be present. Testing helps assess contamination, verify cleanup, and ensure spaces are safe for use.

Initial Bacteria Assessments
Pre-remediation evaluation to determine the presence and extent of bacterial contamination in affected materials and surfaces.
Post-Remediation Clearance Testing
Final testing to confirm that bacterial levels have been reduced to safe or non-detectable levels following cleanup.
Fecal Coliform, Total Coliform, and E. Coli Detection (Presence/Absence)
Targeted microbial testing for indicators of fecal contamination using culture-based or molecular methods.
ATP (Adenosine Triphosphate) Cleaning Verification
Rapid post-cleaning assessment using ATP meters to detect organic matter, helping confirm effective sanitation.
Quantitative & Qualitative Results
Clear reporting with either presence/absence results or quantified data (e.g., CFU/cm² or MPN counts) for documentation and compliance purposes.

Sulfur Gases

We provide specialized air sampling and analysis for sulfur-based gases that may be responsible for strong odors or potential health effects in indoor environments.

Passive Monitoring with SUMMA Canisters – ASTM D5504-12

Using ASTM D5504-12, a sensitive analytical method, we perform air sampling with SUMMA canisters to detect and quantify sulfur-based gases such as:

- Hydrogen sulfide (H₂S) – commonly linked to “rotten egg” odors and sewer gas

- Carbon disulfide (CS₂) – present in some industrial emissions and contaminated indoor air

- Methyl mercaptan (CH₄S) – a strong-smelling compound associated with waste and decomposition

Results are evaluated against occupational (OSHA, ACGIH) and environmental exposure limits to identify potential odor sources and assess health risks.
Suitable for residential, commercial, and industrial applications.

Respirator Fit Testing

Ensure your team’s safety and regulatory compliance with our professional respirator fit testing services. We provide qualitative fit testing in accordance with OSHA 29 CFR 1910.134 and all applicable federal, state, and local regulations.

Qualitative Fit Testing – California Compliance

Cal-OSHA-compliant qualitative fit testing for N95, P100 half-face, and full-face respirators using approved test agents (Bitrex or Saccharin). This method assesses the respirator’s seal by evaluating the wearer’s ability to detect the test agent under a controlled protocol.
