Penn E&R Providing Time-and Cost-Saving In-Situ Injection Services

Posted January 23, 2020 By Ashley Csaszar

There are many approaches to contaminated site remediation and the treatment of impacted soil, ground water and air.  Formerly an often long, arduous and costly process, conventional ex-situ remediation methods, such as excavation, pump-and-treat systems, etc., are being replaced by innovative in-situ treatment solutions.  Endorsed by regulatory and science-based agencies, including the United States Environmental Protection Agency and Interstate Technology Regulatory Council, solutions such as in-situ remedial injection technologies are proving to be more strategic, efficient and cost-effective.

Penn Environmental & Remediation, Inc. (Penn E&R) is highly experienced in implementing these cutting-edge in-situ injection services aimed at destroying chlorinated and non-chlorinated contaminants.  Our remediation engineers, scientists and technicians have taken the time to adapt to industry changes and diversify their expertise by learning the advanced science behind the following in-situ injection services:

In-Situ Chemical Oxidation – Involves the injection of specific chemicals into targeted locations in the subsurface.  When the injected chemical and chlorinated solvent make contact, it produces a chemical reaction that destroys the contaminant, reducing toxicity to acceptable standards.

In-Situ Bio-Injection – Involves the injection of cultured microorganisms into the subsurface for the purpose of biodegrading soil and ground water contaminants.  In addition to the injection of microbes, a substrate is injected to provide a nutrient source.  The microbes feed on the amendment, oftentimes emulsified vegetable oil, and through their transpiration process destroy the contaminant.

Our industry experts have implemented these innovative in-situ remediation injection services at multiple project sites including the following:

  • Former Stainless Steel Manufacturer (Southeastern PA):
    In-Situ Chemical Oxidation
  • Former Munitions Factory (Southeastern PA):
    In-Situ Chemical Oxidation
  • Former Tubing Manufacturing Facility (Southeastern PA):
    In-Situ Bio-Injection Remediation
  • Former Turbine Components Facility (Southcentral CT):
    In-Situ Bio-Injection Remediation
  • Former Manufacturing Facility (Northeastern NJ):
    In-Situ Bio-Injection Remediation

If you have a site where our in-situ injection services may be useful please contact a Penn E&R professional at 215-997-9000.
