VIPER Environmental Test Systems for Vapor Intrusion Design

VIPER Environmental Test Systems give Clean Vapor the ability to design vapor intrusion mitigation systems using real-time data instead of assumptions. By capturing pressure field extension (PFE) data instantly, we can see how a system will perform before it’s installed, leading to faster decisions, more accurate designs, and fewer surprises during construction. If your project depends on system performance, compliance, and long-term reliability, VIPER changes how those outcomes are achieved.

What Is the VIPER Environmental Test System?

The VIPER system is a proprietary testing platform that measures pressure field extension (PFE) in real time. In simple terms, it simulates how a mitigation system will perform by emulating multiple extraction points and capturing how air moves beneath a building slab. Traditional testing relies on inducing a vacuum at a single point, collecting readings manually, and repeating the process across the site. VIPER replaces that approach with continuous, real-time data collection, allowing our team to evaluate system performance instantly. Instead of waiting hours or days to interpret results, we can see how the subsurface responds as testing happens. That visibility changes how quickly and accurately a system can be designed.

Why Traditional Testing Falls Short

Most pressure field extension testing is still done manually. Technicians move from point to point, pulling readings one at a time, then compiling the data later to build a system design.

That process creates limitations:

Fewer data points collected across the site
Delayed interpretation of results
Higher labor demands and longer timelines
Increased risk of missing critical performance zones

In some cases, decisions are made based on incomplete information simply because collecting more data would take too long.

VIPER removes those constraints. By collecting high-resolution data across multiple points at once, it delivers a clearer picture of subsurface conditions without slowing the project down.

How VIPER Improves System Design

VIPER transforms testing from a static snapshot into a live performance model. By measuring radius of influence (ROI) in real time, we can determine:

How far each extraction point will impact the subsurface
Where additional points are needed, or not needed
What fan sizes and flow rates will perform best

This allows Clean Vapor to design systems with precision before installation begins. On complex sites, that level of insight makes a measurable difference. Instead of designing conservatively or overbuilding to compensate for uncertainty, we design based on actual site behavior. The result is a system that performs as intended, without unnecessary adjustments after installation.

What This Means for Your Project

VIPER doesn’t just improve testing, it improves outcomes across the entire project. With real-time data driving the design process, you gain:

Faster turnaround times Testing, evaluation, and decision-making happen in the same window, not days apart.
More accurate system design Extraction points, fan sizing, and system layout are based on actual site performance, not assumptions.
Reduced risk of system failure By validating performance before installation, we lower the chance of underperforming systems or costly redesigns.
Lower labor and project costs More data collected in less time means fewer site visits and more efficient use of resources.
Cleaner reporting and visualization Data is automatically organized and ready for analysis, improving communication with consultants, stakeholders, and regulators.

For projects where performance matters, and where delays or redesigns carry real cost, this level of clarity changes the equation.

Real-World Results with VIPER

The value of VIPER shows up quickly once testing begins. On one project, real-time data revealed two optimal performance zones beneath the slab, something a traditional approach would likely have missed. That insight directly impacted system design and improved overall coverage. On another site, previous testing suggested that a sub-slab depressurization system (SSDS) would not be effective. Using VIPER, we identified that a sump pit was limiting performance. After adjusting the system to focus vacuum on the sub-slab soil gas layer, the radius of influence improved significantly, turning an unworkable solution into a viable one. In another case, we were brought in strictly to perform testing. After seeing the quality and speed of the data, the client expanded our role to include system design and installation. These aren’t incremental improvements. They’re the difference between guessing, and knowing.

Where VIPER Is Used

VIPER is best suited for industrial and commercial existing buildings, where subsurface conditions are unknown and performance cannot be assumed.

It is commonly used in:

Operating industrial facilities
Commercial redevelopment projects
Sites requiring detailed consultant oversight
Buildings where mitigation performance must be verified before installation

Because new construction sites often have more predictable subsurface conditions, VIPER is typically deployed where uncertainty is highest, and where better data has the greatest impact.

It’s especially valuable for teams that prioritize:

Data-driven decision-making
Faster project timelines
Reduced long-term risk

Built Into Clean Vapor’s Design Process

VIPER isn’t a standalone service, it’s a critical part of how we design systems that perform.

At Clean Vapor, every project follows a structured approach:

Diagnose → Design → Build → Monitor

VIPER strengthens the most important phase in that process, the transition from diagnosis to design.

By collecting real-time PFE data, we move into design with clarity:

We know how the subsurface responds
We know where performance is strongest
We know how the system should be configured

That insight carries through the entire project. Installation is more efficient because the design is already validated. Monitoring is more predictable because the system was built on real performance data.

Instead of adjusting systems after installation, we get it right before construction begins.

Get Real-Time Data Before You Commit to a System Design

If your project depends on system performance, waiting on outdated testing methods creates unnecessary risk.

VIPER gives you immediate insight into how your mitigation system will perform, so decisions can be made faster, designs can be built with confidence, and projects can move forward without guesswork.

Whether you’re evaluating options, validating a design approach, or preparing for installation, Clean Vapor can help you apply real-time data to the decisions that matter most.
