PetroFix Direct Push Injection Planning
Please follow the specific handling, injection tips, and field distribution verification steps recommended. Examples include having long, multi-port injection tips and budgeting a few hours for Day 1 field distribution observation and adjustments. Please review:
In addition to best practices addressed in the “Pre-Application” planning resources, it is recommended you review the available application instructions. Some practitioners opt for a clear water post-injection flush at the end of their injection activities.
Please note, PetroFix takes up to a few months to fully attach to soils. If PetroFix is >100 mg/L in concentration (difficult to see through a 40 ml VOA), it is recommended groundwater not be sampled. Each PetroFix shipment comes with one (1) a colorimetric field test kit taped to the top of a tote or drum to help assess field concentrations. For additional information, please review the “Groundwater Sampling Guidance Document”.
PetroFix Well Injection Planning
When storing the PetroFix material prior to application, it is important to prevent it from freezing or from prolonged exposure to temperatures above 95°F.
The key to a successful well application is to have properly screened wells where the screen is confined across your treatment zones only. We recommend you use a water tight injection attachment to the top of your well and apply PetroFix under low pressure (commonly 20-30 psi). Optimally, you can construct your monitoring wells with a male NPT thread so receive a female threaded injection hose adapter. If you are using existing injection wells you can use ratchet straps that prevents gluing any attachments fittings to a well. Please consult with your injection contractor for their recommended method to inject into your monitoring well(s). Flushing by gravity feed into wells is not recommended. When complete some practitioners opt for a clear water post-injection flush at the end of their injection activities. If your site has a high number of wells we recommend that you install a single well and do a pilot injection prior to full-scale implementation to verify the ability to inject PetroFix at the specified volumes.
Please note, PetroFix takes up to a few months to fully attach to soils. If PetroFix is >100 mg/L in concentration (difficult to see through a 40 ml VOA), it is recommended groundwater not be sampled. Each PetroFix shipment comes with one (1) a colorimetric field test kit taped to the top of a tote or drum to help assess field concentrations.

PetroFix Excavation Planning Document
When storing the PetroFix material prior to application, it is important to prevent it from freezing or from prolonged exposure to temperatures above 95°F.
In most cases, PetroFix is spray applied to the base of an excavation following soil removal. Prior to spray-applying the material, PetroFix should be diluted with water. Determine the amount of dilution based on the ability to safely spray and fully coat the base and sidewalls of the excavation. Larger excavations tend to require more dilution water (2:1 dilution or higher) for the spray “reach” into the excavation. A suggested dilution is provided on your output page, but modify as needed.
PetroFix material can reach nearby wells outside of the application area (usually a few feet away) following injection or into newly installed wells in your excavation location. Please note, PetroFix can take up to a few months to fully attach to soils. If PetroFix is observed in wells >100mg/L in concentration, it is recommended groundwater not be sampled (difficult to see through a 40 ml VOA). Each PetroFix shipment comes with one (1) colorimetric field test kit taped to the top of the tote or drum to help assess field concentrations. For more information, please review the “Groundwater Sampling Guidance Document”.
