Semiconductor Group Site, Norristown, PA |
 TPMC’s
Water/Wastewater Resources Group, formerly Sustainable Resources Group
Inc. (SRG), has operated and maintained a groundwater treatment system
at the client’s site since the installation of the system in 2000. The
system treats groundwater contaminated with Volatile Organic Compounds,
primarily trichloroethylene. In addition to the groundwater system, a
soil vapor extraction system was installed and operated by SRG. The
original treatment system design components included air stripping,
nano-filtration, chemical addition, and carbon treatment of the
recovered groundwater. SRG assisted in determining that the
nano-filtration and chemical addition included in the original design
were not necessary for successful GWTP operation, and that discharge
standards could be attained with air stripping and carbon treatment.
SRG provides operation and maintenance, system optimization, compliance
sampling and reporting. |
| Wastewater Pretreatment System
Design/Building, Operations and Maintenance, Tank Management and
Facility Decontamination, Crayola, Bethlehem, PA |
 TPMC’s
Water/Wastewater Resources Group, formerly SRG, provides oversight of
the operation of an industrial wastewater pretreatment facility for a
plant manufacturing art supplies. The contract is a follow-on to the
company’s 1997 work to design and build a treatment system to remove
solids and metals prior to discharge to the municipal wastewater
system. The system utilizes chemical precipitation and filtration to
remove the solids and metals. SRG is responsible for the operation and
maintenance utilizing client staff. |
Ground Water Remediation/ Operations
& Maintenance, Purex Industries
Millville, NJ |
 Since 1994, TPMC’s Water/Wastewater
Resources Group, formerly SRG, has been providing remediation services
for the cleanup of site and groundwater contamination at this client’s
site. The contaminants include Volatile Organic Compounds, primarily
trichloroethylene along with jet fuel and gasoline. The groundwater
treatment system consists of a series of 13 recovery-wells designed to
pump 375,000-gpd of contaminated groundwater to the facility. A
UV/peroxide oxidation process utilized ultraviolet light with hydrogen
peroxide for destruction of organic compounds. This process is highly
effective for treating TCE, the main contaminant. The UV/oxidation
process is followed by a shallow-tray air-stripper and the treated
effluent is recharged through a series of injection wells and trenches.
Currently, SRG provides operation and maintenance services of the
groundwater treatment system collecting, reviewing and maintaining all
process data and operating logs. SRG prepares and submits the remedial
progress and operations reports to regulatory authorities. |
Groundwater Treatment Plant, US Navy,
NAVFAC Mid-Atlantic
Bethpage, NY |
 TPMC’s Water/Wastewater Resources Group,
formerly SRG, supported this Department of Defense client. SRG provided
operation and maintenance (O&M) activities, system
optimization, site management, and technical reporting services for the
client’s inactive facilities groundwater treatment plant. The GM-38
Area system is designed to treat up to 1,200 gallons per minute
groundwater contaminated with trichloroethylene tetrachloroethylene,
and carbon tetrachloride extracted from two recovery wells and
processed through a packed column air stripper followed by a liquid
granular activated carbon treatment. |
