Complete Vapor Intrusion Assessment and Soil Gas Testing Solutions in Southern California by Soil Vapor Extraction Service Inc
From initial assessment to detailed sampling and methane testing, we ensure your site meets California compliance standards and keeps occupants safe.
Why Vapor Intrusion and Soil Gas Risks Can’t Be Ignored
Vapor intrusion hiding beneath your property? It’s an invisible threat. VOCs and methane are harmful gases and can migrate from contaminated soil or groundwater into buildings and put the health and safety of residents at serious risk.
Here’s the reality:
- It comes with health hazards as toxic vapors lead to long-term exposure risks for occupants.
- Failing to test can trouble you with lawsuits. It results in failed inspections and costly project delays.
- California DTSC and local agencies require vapor assessment before development or occupancy.
Even brand-new construction projects have failed final approvals because soil gases weren’t tested properly. One missed step can cost thousands in redesign and delays.
S.V.E. Inc. never lets your project experience delays. We’ve designed a step-by-step testing approach to keep your property compliant, safe, and on schedule.
Step 1: Vapor Intrusion Assessment To Identify Risks Before They Become Problems
Every project needs to start with a thorough vapor intrusion assessment to ensure safety and compliance. This is where we identify risks early so they never become expensive surprises later.
What S.V.E Inc. does in this phase:
- Comprehensive site evaluation and historical review
- Preliminary soil gas checks following DTSC and EPA guidelines
- Clear reporting so you understand the risks and next steps
S.V.E Inc.’s certified team understands the earlier detection of vapor risks to keep your project moving faster towards completion without costly interruptions.
Once risks are mapped, it’s time to install the right monitoring points for accurate testing.
Step 2: Soil Vapor Probe and Well Installation For Accurate Monitoring for Reliable Data
Reliable data starts with the proper installation of vapor probes and wells. Our certified crews install both temporary and permanent probes, depending on your project needs.
- Installed at precise depths to meet DTSC and local regulatory standards
- Secure seals to prevent cross-contamination
- Set up for both short-term investigations and long-term monitoring
With your monitoring points in place, we move on to collecting soil gas and sub-slab samples for lab analysis.
Step 3: Soil Gas and Sub-Slab Vapor Sampling For The Data Phase
This is where science meets precision. Our experts collect soil gas and sub-slab vapor samples using approved methods for accurate, defensible results.
- Detecting harmful VOCs such as TCE and PCE
- Critical for risk evaluation and mitigation design
- Full compliance with California DTSC and EPA guidelines
What about methane risks? You can’t ignore methane testing if your site is near a landfill or has organic-rich soil.
Step 4: Methane Gas Testing For Keeping Your Project Safe and Code-Compliant
Building on methane-sensitive land without testing is a major safety hazard and a compliance violation.
- Detect explosive methane concentrations before construction
- Meet strict city and county building codes in Southern California
- Avoid delays and fines
- You save your project from life-threatening risks
Our methane testing ensures your site meets every requirement before you break ground.

FAQs
Contaminated soil or groundwater has harmful gases that convert into vapors and enter buildings through cracks and openings to become part of the indoor air. This happens because of vapor intrusion.
We test using soil gas and sub-slab vapor sampling based on DTSC and EPA guidelines.
Soil gas and sub-slab sampling are important for understanding the full vapor pathway. Soil gas shows conditions in the subsurface. Sub-slab sampling confirms what’s happening directly beneath the structure.
Depth varies by site and regulatory requirements, but probes are installed at precise depths to ensure accurate, uncontaminated samples.
Absolutely. Methane testing is required for sites near landfills or organic soils. We ensure your project meets California Building Code requirements.
We need a few days to a week to complete assessments, as it depends on the size and complexity of your project.
