Bioremediation: Principles, Techniques, and Applications
LSP Course #: 1467
Course Description:
Over the past 40+ years, injection of biostimulation amendments including oxygen release
compounds, carbon substrates, and sulfate compounds has evolved into a viable, cost‐effective
technology for stimulating bacteria for biodegradation of a variety of contaminants, including
petroleum hydrocarbons, chlorinated solvents, nitrate, perchlorate, explosive compounds, acid
mine drainage, and chromium. Using engineering and hydrogeology concepts, the
bioremediation technology is easily customized to meet site‐specific design criteria.
Bioremediation is a natural, safe, and cost effective technology.
This course will provide attendees with an understanding of basic microbiology principles,
sampling techniques and analysis to better assess site microbiology, and approaches to
biostimulate/bioaugment an identified treatment zone. Various bioremediation techniques will
be described with advantages and disadvantages highlighted. The course will also provide
practical suggestions on how to design a project and inject bioremediation amendments in the
field.
The course presenter, Jack Sheldon of Antea Group, has over 30 years of experience as a project
manager and program director. He specializes in the field application of various types of
bioremediation and chemical oxidation systems. He has completed remediation projects in all 50
states and several locations abroad. His full resume is attached.
The course will begin with an overview of aquifer geochemistry and the various factors that
influence microbial processes (Part 1), followed by transport theory as applied to in situ
bioremediation project design (Part 2), and the course will conclude with field case studies (Part
3) illustrating the application of bioremediation under both aerobic and anaerobic conditions.

Former Louisville Downs Racetrack, Kentucky, USA, In‐situ Bioremediation (Aerobic) – Senior Project Scientist for
an in situ treatment system that intermittently operated in air sparging/biosparging and soil vapor
extraction/bioventing modes at the site in Louisville, KY. The system treated clay overburden and silt sediments
found in deep fractures in the underlying bedrock. Initially, a fixed‐film bioreactor was used to treat extracted
groundwater.
Abandoned Lodi Plant, New Jersey, USA, United Technologies Corp., In‐situ Bioremediation (Aerobic)/SVE ‐
Project Manager for a large in situ bioremediation/soil vapor extraction system treating soil and groundwater
impacted with toluene at an abandoned facility in Lodi, NJ. Site reached no further action in four years.
Six Flags Great Adventure Amusement Park, New Jersey, USA, Six Flags Amusement Co., SVE ‐ Project Manager
for an ex‐situ soil vapor extraction system operated at the Six Flags Great Adventure Amusement Park in Jackson,
NJ. The project involved extracting gasoline from sandy soils and treating vapors through carbon adsorption. The
project reached closure after nine months of treatment. Extensive vapor monitoring was conducted because of
the proximity to live animals in a Safari Park.
Manufacturing Plant, Confidential Client, Wisconsin, USA, In‐situ Chemical Oxidation – Senior Project Scientist
for a multi‐depth ozone sparging application for a chlorinated solvent groundwater plume in southern Wisconsin.

This application was estimated at half the cost of a previously recommended ZVI barrier and was more practical in
dealing with the depth to groundwater (>50 ft.) at the site.
Brownfield Property, City of Louisville, Kentucky, USA, In‐situ Chemical Reduction ‐ Senior Project Scientist for a
Brownfield site slated for development into senior citizen housing. The site was impacted by PCE/TCE from a
former drycleaning operation. Evaluated site investigation data and developed list of potential cleanup
technologies. In‐situ chemical reduction was selected for cost estimation and a conceptual design.
Selected International Project Experience
Tai‐kak Channel, Hong Kong, China, Hong Kong Development Corp., Sediment Washing/In‐situ Chemical
Oxidation – Senior Project Scientist on a high profile sediments treatment project in the main channel in Hong
Kong, adjacent to the old airport. Both sediment washing, using the Biogenesis process, and in situ chemical
oxidation, using modified Fenton’s reagent, were demonstrated at the bench‐scale on the metals/organics‐
impacted sediments. Demonstration results were evaluated and a risk assessment conducted. A strategic plan will
be developed to evaluate other technologies and to allow reuse of the sediment and future development of the
channel.
Manufacturing Plant, Sanmina, Canada – Site Investigation/Pump & Treat Optimization ‐ Senior Project Scientist
providing oversight of work scopes prepared by Inogen partner, DCS. Project involves additional investigation of
CVOC impacts through well installation and sampling program. Also, existing Pump & Treat system is being
optimized to provide maximum capture prior to coupling with a source reduction approach.
Asti Plant, Italy, United Technologies Corp., MNA – Senior Project Scientist on one of the first MNA projects in the
Asti region of Italy. The site was a former automotive parts manufacturing facility that used air sparging/SVE to
treat chlorinated solvents in soil and groundwater. The project was transitioned into an MNA remedy for
polishing.
Air Bag Manufacturing Plant, France, Herakles, Feasibility Study, ‐ Senior Project Scientist on the evaluation of
biological and non‐biological technologies for source area and plume control of a large perchlorate and CVOC
plume. Providing expertise on conceptual model development and design study for a permeable reactive barrier.
Manufacturing Plant, Pirelli Tire, Italy, In‐situ Chemical Oxidation ‐ Senior Project Scientist for a pilot study using
Fenton's reagent to treat heating oil. This was one of the company's first application of chemical oxidation.
Designed study, collected data, and prepared report. Heterogeneous soil lead to evaluation of other technologies
to remediate the site as chemical oxidation gave inconsistent results.
Wood Treatment Plant, Carter‐Holt‐Harvey, Australia, In‐situ Geochemical Reduction ‐ Senior Project Scientist for
a full‐scale chromium cleanup in groundwater using calcium polysulfide injection. Reviewed data and prepared
progress reports. Tasked with evaluating the site microbiology on a regular basis using a variety of microbial
assays to understand impact of reductive environment on the indigenous bacteria.
Former Manufactured Gas Plant, Confidential Client, UK, In‐situ Bioremediation ‐ Senior Project Scientist for a
pilot study using injection of an oxygen release compound into a small plume with mostly lower molecular weight
PAHs. Designed study, collected data, and prepared report. Prepared full‐scale workplan.

Manufacturing Plant, Grace, Brazil – In‐situ Chemical Reduction ‐ Senior Project Scientist for technology selection,
pilot test design and monitoring for an in‐situ chemical reduction approach in a source area impacted by CVOCs in
tight media. Evaluated distribution of the amendment following direct push and hydraulic fracturing. Reviewed
progress reports and also offered guidance on vapor intrusion studies performed at the site. This effort was in
support of Inogen partner, ANGEL.
Manufacturing Plant, HB Fuller, Brazil – In‐situ Chemical Reduction ‐ Senior Project Scientist for technology
selection, pilot test design and monitoring for an in‐situ chemical reduction approach in both on‐ and off‐site areas
impacted by Carbon Tetrachloride and Chloroform in tight media. Evaluated distribution of the amendment
following direct push, soil mixing and hydraulic fracturing. Developed progress reports and participated in client
meetings.
Manufacturing Plant, Confidential Pharmaceutical Client, Sweden ‐ Plume Forensics/Feasibility Study ‐ Senior
Project Scientist for development of a plume responsibility strategy and negotiation between responsible parties
and regulators. Prepared overall feasibility for remediation technologies that could be applied to the plume areas.
Public Landfill, Confidential Client, Taiwan, ‐ Litigation Support – Senior technical support conducting a literature
search to document fate and transport for individual CVOCs and biodegradation mechanisms.
Parts Degreasing Plant, Confidential Client, Brazil – In‐situ Bioremediation (Anaerobic) ‐ Senior Project Scientist
for data review and injection optimization of an emulsified vegetable oil injection for TCE in groundwater.
Evaluated distribution of the amendment and ability to create anaerobic conditions and increase organic carbon.
Helped local office prepare report for regulators.
