Frequently Asked Questions

Prioritize safety first: eliminate ignition sources, keep people clear of the area, and prevent the material from reaching a storm drain or waterway if it’s safe to do so. Then call ERC’s emergency line — don’t wait to assess the full extent before calling.

Yes. ERC responds to transformer oil releases, including the additional handling and disposal requirements that apply when PCBs are confirmed to be present.

In-situ remediation treats contaminated soil and groundwater in place — using bioremediation or chemical oxidation, for example — without excavating or removing the affected material. It’s typically used when excavation would be too disruptive or costly relative to the contamination present.

Yes. ERC coordinates waste profiling, transportation, treatment, and disposal as part of an environmental project. Requirements depend on the waste classification, project location, and receiving facility.

Landfill corrective action addresses the gasses, leachate, and other byproducts a landfill generates over time, typically through capping systems, leachate collection, and gas management infrastructure. ERC performs this work for active, closed, and coal ash landfill sites.

Yes. ERC installs remedial systems — including soil vapor extraction, sub-slab depressurization, and similar technologies — to treat contaminated soil and groundwater without full excavation.

Yes. ERC designs and constructs wetlands, and restores existing wetlands that have been degraded or damaged, for both private and municipal clients.

Yes. ERC has completed dam removal and reservoir, canal, and shoreline restoration projects, including a low-head dam removal for a municipal client in Dayton, Ohio.

Yes. ERC provides cleanup services for illegal dumping sites and vacant or unauthorized encampments, including hazardous and non-hazardous material removal, for municipalities and private property owners.

Yes. ERC operates vacuum trucks and trailers for removing liquids, sludge, and other regulated materials from tanks, sumps, and containment areas, for both planned projects and emergency response.

It helps to know the general location and nature of the issue — a suspected contamination source, a tank you’re looking to remove, or a restoration project you’re planning — but you don’t need a full site assessment before reaching out. We’ll help scope the next step.

Yes. Our case studies page includes completed projects across storage tank removal, soil and groundwater remediation, demolition, and ecological restoration, with the actual clients and engineers involved.
