Groundwater Treatment System Design -
Collection & Treatment with Air Stripping Technology
Bridgeport, Ohio
Scope:
- Technology Evaluation
- Treatment System Design
- Construction Oversight
- Startup
- Operation & Maintenance
This site is a former
bearing manufacturing plant and was mostly recently used for the manufacture
of specialized pipe fixtures. Historical activities at the plant resulted in
the contamination of groundwater with volatile organic compounds (VOCs). A
treatment system to remove the VOCs was determined to be the most effective
remedy for the groundwater contamination. Advanced GeoServices
designed a cost effective groundwater extraction and treatment system to
treat the VOC-contaminated groundwater. The treatment system is comprised of
a 1500 square foot treatment building, three extraction wells (total flow of
25 gpm), two shallow tray air strippers, liquid and vapor phase activated
carbon, and a PLC system for remote monitoring. Advanced GeoServices also
prepared a long-term monitoring and maintenance plan for the treatment
system. Advanced GeoServices is currently contracted to operate and maintain
the treatment system. A subsequent calcium carbonate sequestering system was
designed and installed and is significantly reducing the calcium carbonate
precipitate. |

Calcium Scaling Abatement at a
Lead-Acid Battery Manufacturing Plant
Reading, Pennsylvania
Scope:
- Bench-Scale Study
- Scale Identification
- Feasibility Study
- Engineering
- QA/QC
- TDS Evaluation
A battery manufacturing facility has a 0.5 Million Gallons per
Day (MGD) Wastewater Treatment Plant (WWTP) that discharges to the
Schuylkill River. The treatment process consists of equalization followed by
metals precipitation (pH adjustment using lime). Solids are processed
through a belt press and disposed off-site. The wastewater is conveyed
through a ½ mile long pipe before discharging to the Reading Stormwater
Collection System. The stormwater collection system discharges to the
Schuylkill River. Calcium sulfate was forming and collecting inside the
discharge pipe causing backup of treated wastewater. The discharge line
required continuous maintenance to remove the scaling. Permit exceedences
for Total Dissolved Solids (TDS) was also an issue at the plant.
Advanced GeoServices conducted the following activities at the plant:
identification of scale; feasibility study of scale abatement and TDS issue;
capital and maintenance evaluation; recommendations for scale control;
engineering for recommended solution; and installation of a chemical
sequestering system |

Turnkey Design/Build Remediation & Groundwater Treatment
Montgomery County, PA
Scope:
- Investigation
- Remedial Design (RD)
- Turnkey Construction
- Litigation Support
This site was formerly used
for the manufacture of computer chips. Investigations had been performed by
others between 1980 and 1993 to evaluate the magnitude and extent of TCE
contamination that resulted from an underground solvent tank leak. The site
was listed on the NPL in 1989 and an RI/FS was subsequently performed. The
RI identified an area of groundwater contaminated with Volatile Organic
Compounds (VOCs) within the fractured bedrock aquifer. The migration of the
contaminant has been complicated by local water supply wells. The selected
remedy in the Record of Decision (ROD) included a large-scale (several
hundred gpm) groundwater pump and treat system, installation of a public
water supply line, maintenance of whole-house carbon filters, and
establishment of a groundwater management zone and institutional controls.
Advanced GeoServices was contracted to complete the design and construction
of a 150 gpm groundwater treatment plant to remove VOCs, sulfate, metals,
and hardness. The treated groundwater will be delivered to the local public
water supply system in close cooperation with the public water supply
company. Design of the system was completed in July, 1999 and was followed
immediately by turnkey construction that started in August of 1999. Advanced
GeoServices is the design/builder and provided on-site engineering and
construction management services. |

Oil / Water Separator for Industrial Facility
Lampeter, PA
Scope:
- Design
- Installation
- Startup
A battery manufacturing plant was
exceeding oil and grease discharge limits established by the local POTW. A
preliminary investigation indicated that an oil water separator would
significantly reduce oil and grease concentrations. Advanced
GeoServices conducted a bench scale study. The bench scale study results
indicated that pH adjustment was necessary to help remove the oil and grease
from the wastewater. An oil/water separator, pH adjustment, neutralization,
and associated wastewater conveyance systems were designed and installed by
Advanced GeoServices. Existing tanks on-site were effectively incorporated
into the design to reduce capital costs. Advanced GeoServices worked closely
with plant personnel in establishing the Operation and Maintanance Plan for
the system. |

Groundwater Remediation via H2O2
and Carbon Treatment
Beverly, NJ
Scope:
- Construction Oversight
- Quality Control
- Engineering Design
- Regulatory Reporting
- Startup / Commissioning
- Operation & Maintenance
- Operations Reporting
- Surveying
- Groundwater Monitoring
- Operations & Maintenance Plan
- Groundwater Monitoring Plan
- Startup & Commissioning Plans
The former
Cosden Chemical Coatings plant formerly manufactured paint products. Leaks
from tanks/drums and waste disposal practices caused soil and groundwater
contamination with VOCs, PCBs and heavy metals. Groundwater and soil
treatment systems were selected as remedial approaches for the site
contamination. With Environmental Chemical Corporation and the U.S.
Army Corps of Engineers, Advanced GeoServices conducted quality control and
construction oversight during the construction phase of the groundwater and
SVE treatment systems. After construction was completed, Advanced
GeoServices performed the startup/commissioning activities, which entailed
testing the system performance. After startup, Advanced GeoServices
performed the monitoring (air/liquid sampling, data recording, reporting,
etc.). We also provided engineering design support for plant modifications.

- Treatment System Design
- Construction Oversight
- Startup
- Operation and Maintenance
This site is a former manufacturing. Historical activities at
the plant resulted in the contamination of groundwater with volatile organic
compounds (VOCs). A treatment system to remove the VOCs was determined to be

(total flow of 150 gpm), one shallow tray air strippers and a PLC system for
remote monitoring. Advanced GeoServices also prepared a long-term monitoring
and maintenance plan for the treatment system. |

Groundwater Collection, Conveyance &
Treatment System Design - Granular Activated Carbon
Cape Cod, MA
Scope:
- Mechanical Piping Design
- Pump Design
- GAC Treatment System Design
Advanced GeoServices was contacted by a contracting
company for a confidential government client to design a groundwater
conveyance system. Advanced GeoServices prepared the mechanical design
drawings for a granular activated carbon (GAC) system consisting of eight
15,000 lb carbon units in parallel and in series. Design included
selection of extraction well pumps with a total system flow of approximately
1,500 gallons per minute, drawings for four piping manifolds, booster pumps,
influent and effluent piping, valves, and process control equipment, and
infiltration galleries. Project was constructed and currently working as
designed. |

Wastewater Treatment System Feasibility Study for a Lead-Acid Battery
Manufacturer
Manchester, IA
Scope:
- Wastewater System Evaluation
Advanced GeoServices was contacted by a Battery
Manufacturing Facility to evaluate an existing wastewater treatment system
that was exceeding lead discharge standards. In addition, the underground
settling tank was leaking and needed immediate repair. The treatment system
consisted of a primary settling tank, neutralization, co-precipitation,
solids settling tank, Lamilla clarifier, and filter press. Advanced
GeoServices conducted a comprehensive evaluation of the treatment system
components to determine the source of the lead exceedances. Advanced
GeoServices determined that the clarifier was hydraulically overloaded at
times which caused the exceedences and two parallel clarifiers can
effectively reduce the lead discharges. The settling tank was relined to
repair the leaks. In addition, the sludge management system was
overloaded which reintroduced solids back into the treatment system. It was
determined that additional sludge tanks will reduce the sludge overflow.
