What We Do / Consulting / Engineering

Remedial Design and Installation

WCEC has designed, installed and/or operated over 50 remediation systems in Minnesota, over 20 remediation systems in Montana, and over 20 remediation systems in other states utilizing a wide range of technologies for sites impacted by agriculture chemicals, solvents, and petroleum hydrocarbons.

Remedial technologies implemented by WCEC to target dissolved-phase, sorbed-phase or free-phase contaminants include:

• Air Sparging / Soil Vapor Extraction

• In-situ Chemical Oxidation

• Groundwater Pump and Treat

• Multiphase Extraction

• Free-phase Recovery with Automated Skimmer Systems

• On-Site and Off-Site Soil Treatment

Prior to installing a remediation system, WCEC creates an extensive conceptual design, defining anticipated steps needed to reach site cleanup and anticipating life cycle design/costs.  During system installation, WCEC’s knowledgeable and experienced staff works closely with subcontractors to integrate the various system elements according to design specifications.

Solid Waste Landfill Design and Permitting

WCEC's approach to landfill design includes application of time-tested and emerging techniques that enhance environmental protection while controlling costs and protecting the interests of all stakeholders.

WCEC’s team of scientists and engineers are at the forefront of comprehensive landfill facility planning, design, permitting, construction, operations, closure, monitoring and compliance. While developing and implementing new approaches to reduce, reuse and recycle, landfill operations are the backbone of solid waste management.

Landfills are a necessary component of the waste management strategy, driving the need for development of new initiatives and providing safe disposal of materials that cannot be otherwise recovered.
