A: Our analytical results using US EPA Modified Method TO-14A consistently compare well within regulatory established tolerances. When compared to canisters, we have never had a false positive or false negative in our 100+ projects.
A: More than 140 analyses per 24-hour period are possible.
By default, we can monitor up to and including 16 locations. Additional locations can be added for additional cost.
VaporSafe™ can evaluate and confirm its own performance. System accuracy to calibration standards is within 30%. Clients have the option of dedicating one of the 16 ports to calibration gases, so that the system continuously reports its own calibration every three hours or less.
Sample lines can be deployed up to several hundred meters from the staging area.
Why measure blindly without any regard to external controlling factors? We understand that other factors can affect chemistry. To aid decision making, we have created an infrastructure of data that can influence chemistry. We can interface with almost any sensor or API. Today, we deliver the following data as standard, out of the box:
- Real-Time Differential Pressure, via our own fleet of internet connected wireless sensors. This is extremely useful for measuring SSD effectiveness, and/or HVAC influences. Our Wireless Differential Pressure Sensors are compatible with the VaporPin® system and we recommend them for the best results
- Indoor Barometric Pressure
- Nearby airport meteorological data from, any airport in the world
- Local onsite weather conditions via our fleet of portable, internet connected, weather stations (barometric pressure, temperature, wind speed, direction, etc.)
- In addition to measurements, we can also turn fans off and on, open and close summa canisters, et cetera, all in the theme of the Internet of Things (IoT)
Yes! In fact, USEPA guidance suggests that all risk related decisions be based upon the reasonable maximum exposure (RME). Since VaporSafe™ tracks
concentration and controlling factors, temporally precise time-weighted average concentrations can be rapidly generated to account for VI “events” combined with building occupancy. USEPA acknowledges that this is more statistically accurate than randomly timed or long term passive sampling approaches. As such,
VaporSafe TM generated risk assessments are far more defensible than other approaches.
A: Yes! The system has been accepted at multiple US EPA Superfund sites; in US EPA Regions 1, 5, 9, 10; in US States AZ, CA, NH, IN, MA, MI, NH and OH; by the US Navy, US Army Corps of Engineers, and at sites overseen by agencies in Australia, Brazil and Europe.
It takes approximately ten minutes. An additional system can cut that time to five minutes (for additional cost).
Tired of multiple rounds of summa canister deployments that leave you with
more questions than answers? Typical engagements are one week or less (three to five days average) depending on the site. If barometric pressure influences are suspected or possible, we recommend at least three barometric cycles. Engagement duration is dependent on project objectives. For instance, VaporSafe™ has been successfully employed for multiple weeks during mitigation optimization and confirmation and at several Thermal Remediation projects for several months. That’s days, or at most months… not years.
We can provide data on TCE, PCE, 1,1 DCE, cis-1,2 DCE, trans-1,2 DCE, carbon tetrachloride, chloroform, methane and BTEX, as well as several others.
No. Consultants are our customers, and commonly rent VaporSafe™ for their projects. We’ve been asked for our input by consultants, as they consider us a partner with their projects, based on our broad and deep experience with VI sites.
VaporSafe™ is competitively priced, compared to other methods. VaporSafe™ is almost always a much better value when considering:
- The large number of locations at a site that can be monitored
- The large number of analyses generated each 24-hour period
- The ability for VaporSafe™ to run 24×7, without the need for personnel to be present for every analysis
- The ability to remotely track site conditions with colleagues via the Cloud
- The ability to run “cause and effect” tests in a matter of minutes, for quick evaluation of potential remedies, which can help move a “stuck” project to the next phase
- The flexibility to switch back and forth from automated to manual/discrete sample collection and analysis
- The opportunity to tap into our extensive experience (we’ve seen more than most, and offer expert input and recommendations when requested)
The net result is that we can resolve key remaining questions in a single deployment.
As a rough comparison, 24 hours of VaporSafe™ monitoring is about the same cost as 10 canister or passive samples, but VaporSafe™ provides approximately 140 analyses per day, combined with dynamic controlling factor data. Canister and sorbent samples yield a single data point, while VaporSafe™ yields data patterns and correlations, so you can quickly understand your site and resolve challenges.
