Our Services (old 2)

ENVECO’s remediation and restoration services address the smallest, to the most complex, environmental cleanups.  Remediation can be conducted at active or abandoned sites, with no or minimal disruption to active site operations.  ENVECO is experienced in remediating remote and hard to access sites and is known for added value approaches to address environmental liabilities.  Our technical staff have extensive experience assessing and remediating sites contaminated by petroleum, chlorinated solvents, volatile and semi-volatile organics, PCBs, pesticides, herbicides, metals, munitions constituents, and emerging contaminants. We are also qualified to prepare or assist in development of remedial strategies, or the preparation of plans, specifications, and reports.  ENVECO has expertise in:

• Active, Former, and Closed Military, Government, Industrial, Manufacturing, and Commercial / Privately-Owned Site Cleanups
• CERCLA and RCRA Cleanups
• Voluntary Remediation and Brownfield Cleanups
• Contaminated Soil / Debris Removal and Disposal
• In Situ Soil and Groundwater Treatment and Remediation
• Contaminated Groundwater Extraction and Treatment
• Wastewater Recovery and Treatment
• Hazardous Materials Abatement and Disposal
• Contaminated Sediment Dredging, Treatment, and Disposal
• Firing and Shooting Range Cleanups
• Post Remediation Restoration (Return to Productive Use)

ENVECO specializes in processing mixed wastes, minimizing specialized handling and disposal requirements, and generating beneficially reusable solids and water.  Processing significantly reduces project costs and minimizes the volume of wastes requiring specialized handling and disposal.  Solids and water that can be diverted from waste streams and beneficially reused results in a smaller environmental footprint.  Our solids separation and dewatering use a variety of technologies and methods tailored specifically to project requirements, and can be scaled to accommodate any size project.  ENVECO has expertise processing:

• Dredged Sediment
• Slurry
• Sludge
• Tunneling Muck
• Oil and Gas Production Waste
• Wastewater Treatment Plants (WWTP) and Public Treatment Works (PTW) Waste
• Industrial Waste
• Agricultural Waste

ENVECO provides demolition and decommissioning of structures, infrastructure, and features presenting environmental and safety risks and/or requiring specialized certifications, training, processes, and equipment.  During demolition, debris and wastes that can be recycled and beneficially reused are segregated reducing waste disposal costs, minimizing landfilling, and increasing project savings.  Risks to the environment are mitigated through identification, abatement, integration and implementation of best management practices.  ENVECO has expertise demolishing and decommissioning:

• Aboveground and Underground Storage Tanks (ASTs / USTs)
• Bulk Storage Facilities
• Petroleum Oil and Lubricant (POL) Systems
• Infrastructure
• Buildings and Structures
• Waste Storage Areas
• Treatment Systems
• Industrial Processing Facilities
• Firing and Shooting Ranges

ENVECO is highly proficient executing earthwork and construction projects with an environmental component and/or requiring specialized certifications, training, processes, and equipment.  We build to design specifications and can readily adapt to changing or unforeseen field conditions.  Our extensive experience allows us to contribute to project design and sequencing, and identify opportunities to provide added value and savings.  ENVECO has extensive earthwork and construction expertise in:

• Excavation (Shallow and Deep, Open and Shored)
• Erosion and Sediment (E&S) Control
• Stormwater / Surface Water Management
• Retention Pond Construction, Maintenance, and Improvements
• Shoreline Stabilization
• Landfill and Waste Cell Construction, Maintenance, and Improvements
• Cap Construction, Maintenance, and Improvements

ENVECO offers cradle-to-grave management for a wide variety of wastes, from generation through processing, and ultimately disposal/treatment.  We specialize in reducing waste volumes requiring specialized handling and disposal/treatment and identifying beneficial reuse alternatives for perceived wastes.  We pride ourselves on providing beneficial reuse alternatives and options when appropriate, reducing impact to the environment, and addressing contract and permitting requirements.  Some wastes simply require treatment and disposal; our strategic partnerships forged by decades of working with specialized waste haulers and disposal and treatment facilities across the United States and Canada allow us to provide the best T&D costs.  ENVECO can rapidly deploy proven technical solutions in:

• Waste Reduction, Characterization, and Transport and Disposal (T&D)
• Beneficial Reuse Alternatives
• Contaminated Soil and Water
• Liquid and Solid Hazardous Waste
• Hazardous Material Abatement
• Construction and Demolition Debris

ENVECO provides turnkey vapor intrusion mitigation (VIM) from assessment through design, implementation, and operation.  VIM and sub-slab depressurization systems (SSDS) have been designed to mitigate a variety of contaminants (petroleum, chlorinated solvents, methane, etc.) in support new construction and to address concerns associated with existing structures.  Our technical experts are well versed in the numerous types of vapor barriers (VB) and vapor mitigation equipment available. We provide options, explain the limitations, benefits, and cost implications of each option, and ultimately help our clients select the best option or combination of options to address their challenge.  We possess the necessary training and certifications to install and provide oversight and inspections during VB installation.  VIM services include:

• Vapor Intrusion Mitigation Systems (VIMS) Design / Build
• Sub-Slab Depressurization System (SSDS) Design / Build
• Vapor Barrier (VB) Design / Build
• VIMS and SSDS Operation and Maintenance (O&M)
• VIMS and SSDS Optimization
• VIMS and SSDS Construction Oversight and Quality Inspections

Emerging contaminants, such as PFAS, pose risks to human health and the environment that are not yet fully understood presenting significant concerns and challenges. and ENVECO stays informed and is ahead of the curve on how to address the challenges they present.  We also pride ourselves on using and employing the most innovative technologies to complete our work.  Advances in technology have led to safer, more efficient, and cost-effective ways of executing work, expediting schedules and increasing the effectiveness of remedial objectives.  Our strategic partnerships provide cutting-edge services advanced technologies that include:

• PFAS Water Treatment Systems
• Robotic Bulk Storage Tank Cleaning
• Dewatering and Waste Processing using Geotextile Tubes and Advanced Polymers
• Unmanned Aerial Vehicles (UAVs) Surveys and Assessments
