Yes! BioStryke™ saves you the client money by designing innovative processes that are created using the highest quality products, obtained at the lowest available costs, in order to deliver remedial strategies that perform consistently and are available at competitive prices.

02. What is the cost per ton of remediated soil/groundwater?

The cost is 2-3 times less than traditional methods. For example, a typical former gasoline station with an approximate impacted phreatic zone measuring 50x50 feet migrating downgradient from the former USTs, creating a ten foot saturated interval and assuming concentrations of DRO (F2) approximating 1,000 mg/Kg in the soil, and < 1 ug/L in the dissolved phase, with residual source mass present, to require 2-3 times less cost than that associated with tradition excavation and in-situ remedial processes; furthermore, our petroleum hydrocarbon process eliminates the need for any above ground energy consuming system supportive equipment. Similar savings can be realized using our enhanced cVOC remedial formulations, making the time required to attain site compliance mere years, not decades.

03. What is the cost per pound of your amendment?

The use of BioStryke’s enhanced remedial formulations are proven cost effective when applied to a variety of site conditions, including but not limited to,  petroleum hydrocarbon and chlorinated solvents in the phreatic zone of any site. The per pound price of BioStryke’s enhanced products is competitive with current market products which address similar contaminant concerns; however, our per pound amendment efficiencies are demonstrated to expedite site compliance while providing significantly lower overall per ton material effected remedial costs.

04. Does your process require above-ground energy consuming appurtenances?

No, our in-situ processes are completely passive, working with Mother Nature under actual site anaerobic conditions. This passive aggressive process eliminates much of the upfront and long-term Operation and Maintenance costs associated with typical in-situ remedial strategies.

Site Requirements

05. In what geology will the amendment work? Vadose Zone? Clay soils? Glacial Till?

Our BioStryke™ ERDENHANCED™ and BioStryke™ TPHENHANCED™ products are designed to work specifically in the phreatic (saturated) zone of any given site. Our products are demonstrated effective in a variety of soil conditions, including sites consisting of clays to those with preferential pathway creating fractured bedrock. As with any in-situ remedial process, site characteristics which effect groundwater transmissivity — soil porosity, particle size, organic content, pH, etc. — influence the amount, spacing, and frequency of amendment deployment.
At sites where both vadose and phreatic zone contaminants are present, such as above the water table source zones or at the water table smear zones, our enhanced formulations are easily combined to form a treatment train of surfactants combined with amendment formulations and remedial amendment for deployment sequentially, or in combination. These systematic processes are designed to ‘wash’ soil contaminants from the vadose zone, to increase the contaminant flux to the dissolved phase, where BioStryke™ enhanced formulations expedite the passive aggressive destruction of site contaminant mass.

06. Is BioStryke™ ERDENHANCED™ effective against longer-chained hydrocarbons?
     Oil and Gas Industry – Industrial Cleaning

BioStryke™ TPHENHANCED™ is demonstrated to degrade all types of petroleum hydrocarbon based contaminants. The real question is the characteristics of the contaminant type: the longer the hydrocarbon chain the longer it takes to biodegrade; the greater the contaminant concentration the greater the amendment loading demand required; and, the subsurface matrix type, i.e. is the impacted phreatic zone consisting of tightly packed clay or glacial till, or within a coarse grained sand aquifer.

07. Can it be used on pooled NAPL? Ganglia forming and/or sorbed residual mass NAPL?

No, pooled mass must be removed as with all in-situ remedial amendments. BioStryke’s enhanced formulations are proven to destroy dissolved phase, sorbed mass, and residual source mass in a variety of site’s phreatic zones. As with other in-situ remedial amendments, pooled mass continues to require physical removal so as to provide the necessary surface area of the contaminant (level of bioavailability) to which biodegradation processes may prove effective.

08. Can it be used in concert with vadose zone excavation? Polishing?

Yes! Our products work perfectly as a follow-up/polishing treatment process to vadose zone source removal operations where post excavation residual groundwater contamination is present.

Mode of Action

09. Do you require augmentation with introduced microbial populations?

No! BioStryke’s philosophy is to enhance existing site conditions, not augment them. Our processes allow native contaminant degrading microbial populations present to maximize metabolic activities which expedite site contaminant degradation. It is generally accepted that microbial populations suitable to degrade a given contaminant are present at most sites where contaminant impact has been present for a prolonged period of months to years. As such, BioStryke’s proprietary and patent-pending products are designed to enhance existing site conditions, working with Mother Nature to maximize the contaminant degrading capabilities of native microbial populations.

10. How does the amendment distribute within the subsurface matrix? Is it soluble?

Yes, 100% soluble. As noted previously, each of our products is nearly 100% soluble, which makes in-situ and above ground amendment deployment simple, fast, and consistent. Our amendments are delivered dry, allowing for on-site blending at varying concentrations. Furthermore, our solubility and ease of handling/mixing allows for a limitless means of amendment deployment to include direct push injection technology (GeoProbe), injection wells, gravity fed infiltration galleries, etc.

11. Can it be used as a containment process?

No, not necessarily. BioStryke™ conceptual remedial strategies typically deploy the appropriate amendment directly to a source zone, allowing MNA to consist of the long-term remedial strategy. As such, BioStryke™ amendment deployment is designed to eliminate continued source zone contribution to an existing contaminant plume to allow for plume contraction over time; our formulations are not necessarily designed for direct plume migration contaminant, other than via the establishment of a downgradient amendment curtain.

12. Is it effective at source destruction?

Yes! BioStryke’s enhanced formulations are proven to destroy dissolved phase, sorbed mass, and residual source mass in a variety of sites’ phreatic zones.

13. Is it a 'one-size fits all' product(s)?

No, not exactly. No one product is perfect for all site concerns, and that remains true with ours; however, BioStryke™ takes seriously the use of our products, and strives to work closely with each remedial practitioner to understand site conditions, product applicability, and appropriate deployment strategies to ensure effective product performance. As such, BioStryke™ works with each of our clients under an agreed upon Confidentiality Agreement so that the open sharing of site information and product information can be attained to maximize project performance.

14. How is the amendment delivered?

Simple subterranean injection. Our formulations are 100% soluble making amendment delivery simple whether using direct hydraulic push equipment or gravity fed subterranean injection galleries. With regards to ex-situ amendment deployment, our ex-situ amendment formulations similarly dissolve upon contact with water, making deployment possibilities endless. Additionally, our surfactants are biodegradable, non-toxic, and of a consistency making delivery alone, or in combination with our enhancement and/or amendment formulations, simple, safe, and consistent.

Product Delivery and Ordering

15. In what form is the amendment shipped?

The amendment is typically shipped dry in 15 kg bags for smaller projects and in bulk for larger projects. Our products are 100% soluble, allowing us to save you the cost of shipping water, and ensure on-site blending is worry free. Packaging can be modified to meet the needs of any order requirement, to include bulk product delivery throughout the world. Necessary product documentation to include MSDS and shipping labels are included with every order.

Environmental Considerations

16. Is the process sustainable?

Yes, single injection remediation means less impact. Product performance of BioStryke™ ERDENHANCED™  and BioStryke™ TPHENHANCED™ formulations is proven sustainable after only one injection round. The pound per pound effectiveness of our products, and the designed ability to rapidly enhance existing microbial populations to degrade site contaminants quickly, with less site impact, results in greater cost effectiveness.

17. Are ambient air quality concerns generated as a result of the use of your amendment?

Yes, but greatly reduced! With any in-situ remedial strategy designed to degrade chlorinated solvent contaminant, ambient air quality concerns must be addressed; however, these concerns are minimized when one uses BioStryke’s remedial formulation BioStryke™ ERDENHANCED™. BioStryke™ ERDENHANCED™ is demonstrated to shorten the half-life of the various daughter products associated with PCE/TCE and TCA contaminant degradation. As such, the ability of BioStryke™ ERDENHANCED™ to expedite the destruction of the daughter products TCE, DCE, and VC, minimizes the exposure time during which these same contaminants can become an ambient air concern.

18. Are there secondary contaminant issues using your amendment?

No! Our products are designed and amendment loading requirements are established using stochiometric calculations based on a litany of site data points, contaminant metrics, and product values. Each amendment loading/deployment strategy is designed to ensure that complete amendment consumption occurs, preventing the possibility for secondary groundwater compliance issues. Furthermore, our processes are sustainable, setting the stage for and kick-starting the native microbial populations present with only one strategic deployment, targeting the contaminant source zone allowing for a long-term remedial strategy to include Monitored Natural Attenuation (MNA) of the contaminant plume as it contracts. Eventually, no further source material is present upgradient to allow for the plume’s continued and historic expansion.

19. Do I need a membrane for use under occupied building slabs?

No, not so far! Ambient air monitoring is always required using any reductive dechlorination product; however, to date, the use of BioStryke™ ERDENHANCED™ has not required the establishment of a secondary containment structure or engineering control to mitigate ambient air concerns associated with daughter product production.
