FAQ

Frequently Asked Questions about VaporSafe™

1. How do VaporSafe™ results compare to other approaches, such as summa canisters?
A: Our analytical results using US EPA Modified Method TO-14A consistently compare well within regulatory established tolerances. When compared to cannisters, we have never had a false positive or false negative in our 100+ projects.
2. Has the VaporSafe™ system been used by, or approved by, regulatory agencies?
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, OH, the US Navy, US Army Corps of Engineers, and at sites overseen by agencies in Australia, Brazil and Belgium.
3. How many VaporSafe™ analyses are possible during every 24-hour period of monitoring?
A: More than 140 analysis per 24-hour period.
4. How much time does VaporSafe™ need to generate a measurement?
A: Approximately 10 minutes. An additional system can cut that time to 5 minutes (for additional cost).
5. How many monitoring locations per site are possible?
A: By default, we can monitor up to and including 16 locations. Additional locations can be added for additional cost.
6. How long do I need to monitor?
A: Tired of multiple rounds of summa cannister deployments that leave you with more questions than answers? Typical engagements are one week or less (3 days average) depending on the site. If barometric pressure influences are suspected or possible, we recommend at least three barometric cycles. Duration of engagements are 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.
7. How accurate are the measurements?
A: VaporSafe™ can measure its own performance. System accuracy to calibration standards is within 30%. Clients have the option of dedicating one of the 16 ports to calibration gas so that the system continuously reports its own calibration every 3 hours or less.
8. What VOCs can be measured?
A: TCE, PCE, 1,1 DCE, cis-1,2 DCE, trans-1,2 DCE, carbon tetrachloride, chloroform, methane, BTEX, as well as several others. Contact us with your needs.
9. In addition to chemical compounds, what other parameters can you measure?
A: Why measure blindly without any regard to external 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 "out of the box as a part of our standard offering":
1. Real-Time Differential Pressure via our own fleet of internet connected wireless sensors (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.
2. Indoor Barometric Pressure.
3. Nearby airport meteorological data, any airport in the world.
4. Local onsite weather conditions via our fleet of portable, internet connected, weather stations (barometric pressure, temperature, wind speed, direction, etc.).
5. In addition to measurements, we can also turn fans off and on, open and close summa canisters, etc. All in the theme of the Internet of Things (IoT).
10. It sounds like you compete with Environmental Consultants and Engineers. Is this true?
A: No. Consultants are our customers and rent VaporSafe™ for their projects. We have been asked for our input by Consultants as they consider us a partner on their projects, based on our broad and deep experience with VI sites.
11. How much does the VaporSafe™ service cost?
A: VaporSafe™ is competitively priced in comparison to other methods. VaporSafe™ is almost always a much better value when considering:
1. The number of locations at a site that can be monitored.
2. The large number of analyses generated per every 24-hour period.
3. The ability for VaporSafe™ to run 24x7 without the need for personnel to be present for every analysis.
4. The possibility to run "cause and effect" tests in a matter of minutes for quick evaluation of potential remedies, which may help move a "stuck" project to the next phase.
5. The flexibility to switch back and forth from automated to manual/discrete sample collection and analysis.

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 versus 10 cannisters even with expensive 24-hour lab turn around.
