Penn E&R is a leader in the use of innovative remediation technologies. Our process to evaluate and select an environmental remediation program includes technology selection via streamlined feasibility study, and treatability & pilot studies if necessary.
Feasibility Assessments for Technology Selection
We focus on the effectiveness of a remediation technology considering site specific characteristics. Our feasibility studies (FS) mirror the USEPA guidelines for Feasibility Studies Under CERCLA but are refined to be much more efficient. Our process streamlines the development, screening, and detailed evaluation of alternative remedial actions. Our FS process in turn affects the data needs and scope of treatability studies and field investigations. This phased approach results in efficiency in the scoping of the site characterization effort, which eliminates the collection of unnecessary data and maximizes data quality.
We realize that timing regarding the selection, implementation and completion of a remedial action has significant cost implications and often implications on site redevelopment. Remediation Technology screening and selection is not a new science, however recognizing the uniqueness of a site and realizing the implications of such, increases efficiency.
Technology Experience
Penn E&R has direct experience with the screening, selection, designing, permitting, and implementation of the following technologies:

- Precipitation/Flocculation
- Ground Water & Surface Water Including PFOS
In one project, Penn E&R completed the in-situ biodegradation of chlorinated volatile organic compounds in ground water at a former manufacturing facility through implementation of a bioaugmentation/ biostimulation program. This innovative program uses emulsified vegetable oil (EVO) and nutrients (EOS® Pro), Dehalococcoides mccartyi and enzymes BAC-9, and a specific bio-manufactured microbe, Pseudonocardia dioxanssivorans CB1190, to remediate chlorinated solvents and 1,4-Dioxane.
Penn E&R uses an array of models to evaluate remediation technologies and the performance of such. These include Mann-Kendall, BIOCHLOR, SWLOAD5B, J&E, TMS, PENTOX, VISL and various fate and transport models including Xu and Eckstein (1995) and BC2. BC2 is based in part on the Domenico analytical solute transport model (Domenico, 1987), and has the ability to simulate 3-dimensional advection, dispersion, linear adsorption and biotransformation modeled as a sequential first-order decay process.
Penn E&R has published at various national conferences such as the Battelle Annual Chlorinated Conference and The National Ground Water Association Journal – Groundwater.
