LANDFILL
SERVICES
For
more than 30 years, Hydro Geo Chem, Inc. (HGC) has provided high-quality,
award winning environmental services to both the public and private
sector. We have experience on a variety of solid waste issues throughout
the United States. Working with numerous solid waste industry clients
and regulators, we have applied innovative technologies such as
aerobic stabilization of landfill waste; soil vapor extraction (SVE)
and air injection (AI) to remove chlorinated hydrocarbon sources
from deep vadose zones beneath unlined landfills; and pump-and-treat
bio-enhancement technologies for contaminated groundwater plume
containment and cleanup. HGC’s Landfill Technology Group specializes
in servicing the needs of the solid waste industry, with an emphasis
on creative and technically-sound solutions to challenging solid
waste engineering problems. Our background and scope of solid waste
services offered include:
•
Measuring Landfill Gas Generation
• Design of Landfill Gas Collection
Systems
• Reduction of Landfill Greenhouse
Gases
• Aerobic and Anaerobic Bioreactor
Engineering
• Design of Landfill Lining and
Final Cover Systems
• Construction Management
• Landfill Remediation Services
• Charaterization of Soils and
Groundwater Contamination

TECHNOLOGY GROUP KEY STAFF
HGC’s
Landfill Technology Group is nationally recognized for its expertise
in applying advanced hydrologic and geochemical techniques to the
solution of landfill-related engineering problems. Over the last
30 years, HGC has developed a philosophy for environmental management
that has minimized our client’s liabilities and saved them
millions of dollars. This philosophy has been successfully adopted
by our Landfill Technology Group in problems involving the management
of landfill gas, contamination, and landfill bioreactors.

Dr.
Harold Bentley, Ph.D. Dr.
Bentley is Hydro Geo Chem, Inc’s Principal Scientist and is
a recognized expert in the fields of groundwater chemistry, environmental
tracers, and the fate of organic contaminants in the subsurface.
He is the principal developer of HGC's
Baro-Pneumatic Method
for measuring LFG generation,
and has presented several presentations at national and international
seminars related to the measurement of landfill gas generation and
emissions modeling.
Richard
Petrus M.S. has developed Arizona-specific solid waste management
expertise covering landfill design, permitting, construction management,
lateral expansion, and closure. Additionally, he has managed methane
monitoring and abatement projects at several landfill sites.
Stewart
Smith, M.S. Mr. Smith joined Hydro Geo Chem, Inc. in 1989 as
a Hydrogeologist. With over 23 years experience, Mr. Smith performs
numerical modeling of baro-pneumatic data for estimating landfill
gas generation at landfill facilities as well as the performance
of gas collection systems at the conceptual design level.
Warren
Thompson, B.S. Mr. Thompson manages construction
and installation of remedial systems for HGC's landfill projects.
He has installed more than 10 large scale SVE systems with capabilities
ranging from 50 to 2,000 scfm and 3 groundwater pump-and-treat systems
used to remediate VOC contamination beneath landfills.
