Site Assessment & Remediation Services

FINDING PROBLEMS AND FIXING THEM RIGHT

REVERSING ENVIRONMENTAL DAMAGE THROUGH REMEDIATION

When you need solid expertise, we’re here to help. While preventing remediation is clearly the priority, we’ve got enough field experience to understand that with unlined waste units, remediation may be necessary.

When it is, you can count on an solid array of professional expertise, all under one roof, and all designed to help you reframe the negative aspects of environmental remediation and utilize the by-products of remediation (recovered water, etc.) as assets at any project site. From geologists to groundwater specialists, our environmental engineers have vast experience in assessment and remediation.

Environmental Site Assessments (ESAs)

We have a long history performing ESAs for a variety of clients, including pre-purchase property Phase 1 ESAs. These are performed to ASTM standards to assist our clients with obtaining financing and limiting future risk during development.

Our team has significant experience with groundwater impact assessment including alternate source demonstrations, plume delineation, and groundwater modeling. We also have expertise with a variety of remediation techniques and understand what technology will improve impacts depending on site variables.

S+G also has experience with landfill gas assessment including soil gas surveys and landfill gas well installation. We have designed several remedial strategies for landfill gas including passive vent trench systems as well as active landfill gas collection.

Our experience with a variety of impacts and remedial strategies makes us the right choice for environmental assessment

Remedial Design and Implementation

Should environmental impact due to historical practices warrant remedial action, S+G provides design, procurement and implementation services for effective and appropriate remedial options, including:

  • Phytoremediation
  • Enhanced Bioremediation
  • Groundwater Recovery
  • Landfill Gas Recovery
  • Air Sparging
  • Monitored Natural Attenuation

Remediation System Operations and Optimization

S+G provides remedial system operations for a variety of remedial options including strategies for groundwater, soil and air. Our extensive experience with these systems gives us the expertise necessary to effectively optimize these systems and reduce monitoring costs. For our renewable energy clients, our extensive experience with landfill gas to energy systems gives our operators the know-how to optimize LFG recovery and energy production.

Groundwater and Soil Remediation

S+G designs and implements robust, customized remediation solutions for groundwater and soil. Our approach leverages diverse technologies, from natural attenuation to advanced active recovery systems, ensuring cost-effective, long-term site health and the reclamation of valuable environmental assets.

Methane Gas Remediation

Our experts design, implement, and optimize systems ranging from passive venting trenches to advanced active gas collection and control systems, effectively mitigating risks and managing the environmental impacts of methane gas.

Landfill Mining

There are a variety of reasons why landfill mining and recovery may be an appropriate solution for a site – you may need to dispose of waste outside a permitted area, to reclaim property for a redevelopment, or to remove waste for remediation. But in every case, understanding regulations and safety concerns are essential. By balancing financial concerns, long-term goals and regulatory requirements, landfill mining can be a successful and safe solution.

Asbestos Management and Compliance

If asbestos management and disposal is an issue, we’re here to help. We offer a staff of Accredited Asbestos Inspectors in-house to assist you with the evaluation and management of asbestos. Our personnel have significant experience overseeing landfill gas extraction well installation, and other activities performed in waste where asbestos may be present.
