Mining & Extractive Industries

Mining and extractive operations leave a distinct environmental footprint — disturbed soil, legacy waste piles, impacted groundwater, and, at some sites, ongoing risks like underground coal fires that require unconventional remediation approaches. ERC provides the remediation, corrective action, and emergency response mining and extractive industry clients need for both active operations and legacy sites.

Our self-performing crews handle everything from soil and groundwater remediation to large-scale infrastructure work like dam removal, giving mining and extraction clients one contractor for environmental scopes that often span years, not weeks.

Environmental Challenges at Mining & Extractive Sites

Legacy contamination is the defining issue at many mining and extraction sites — soil and groundwater impacts from operations that may have ended years or decades ago, discovered during a property transaction, regulatory review, or planned redevelopment of the site.

Some sites carry unusual, site-specific hazards that require a non-standard remediation approach. Underground coal seam or gob pile fires, for example, can smolder for years and require specialized techniques — not conventional excavation — to fully extinguish.

Water infrastructure tied to extraction operations, including impoundments, reservoirs, and dams, often needs its own remediation or removal work once operations wind down, layered on top of the soil and groundwater contamination itself.

How ERC Supports Mining & Extractive Clients

For legacy soil and groundwater impacts, ERC performs soil remediation and contaminated groundwater treatment scoped to the site’s specific contamination history.

Where a site includes waste piles, impoundments, or legacy landfill areas, our landfill corrective action services manage capping, leachate, and gas control requirements.

For water infrastructure tied to extraction operations, our reservoirs, dams, canals, and shoreline service handles removal, repair, or restoration — see our coal gob fire dam removal case study in Jackson County, Ohio, where ERC drained a reservoir and removed a dam as part of quenching an underground coal fire.

Active-site incidents are handled through our 24/7 emergency response team, mobilizing quickly for spills or releases tied to ongoing operations.

Unconventional Problems Need Unconventional Solutions

Not every environmental problem at a mining or extraction site has a standard remediation playbook. ERC’s project history includes draining a 100-million-gallon reservoir and removing a dam specifically to quench an underground coal gob fire — a scope that required combining civil construction, water management, and environmental remediation into one coordinated project.

That kind of work rewards a contractor who can self-perform across multiple disciplines rather than coordinating separate specialists for each piece of an unusual problem.

Managing Multi-Year Environmental Obligations

Legacy mining sites often carry environmental obligations that span years, not a single project. ERC supports clients through that full timeline, from initial remediation through the ongoing monitoring and corrective action that regulatory closure typically requires.

Whether it’s active-site risk or a legacy environmental obligation, ERC’s environmental remediation team can help scope the work. Contact us to discuss your site.
