Environmental Remediation & Corrective Action

[Remediation]

Solve Contamination Challenges and Restore Your Property’s Value

When environmental contamination is confirmed at a property, the stakes increase quickly. Whether impacts involve soil, groundwater, or vapor intrusion, contamination can impair redevelopment, complicate financing, delay operations, and expose owners to regulatory liability. The key to moving forward is not just knowing that contamination exists — it is knowing how to address it in a practical, cost-effective, and regulator-approved way.

What Environmental Remediation Is — and Why It Matters

Environmental remediation is the process of investigating, managing, and treating contamination in soil, groundwater, and/or soil vapor to reduce risk to human health and the environment and to meet regulatory requirements.

Common contaminants include:

Petroleum hydrocarbons

Chlorinated solvents

Heavy metals

Industrial chemicals and waste byproducts

These impacts often remain in the subsurface long after historical operations have ended and must be addressed before:

Property can be sold or refinanced

Redevelopment or construction can proceed

Regulatory closure can be achieved

Long-term liability can be reduced

A properly designed remediation program protects:

Site users and the public

Property value and marketability

Regulatory compliance and legal standing

Project schedules and budgets

Remediation is not a one-size-fits-all exercise. Every site has different geology, contaminant behavior, regulatory context, and business objectives. CRB’s role is to design and manage solutions that fit the site and the project.

Who Needs Environmental Remediation Services

Clients typically pursue remediation services when:

A Phase II ESA confirms contamination

A lender, buyer, or investor requires cleanup before financing or closing

Redevelopment or construction is planned on a contaminated site

Regulatory agencies require corrective action

Human health or ecological risk must be mitigated

Long-term liability reduction or site closure is the goal

Whether it is a single parcel with localized impacts or a large industrial facility requiring multi-phase cleanup, remediation is a critical step in reducing uncertainty, controlling liability, and unlocking property value.

How CRB Approaches Environmental Remediation

CRB’s remediation philosophy is practical, data-driven, and focused on long-term performance. We blend hydrogeologic science, remedial engineering, and regulatory strategy to deliver solutions that balance effectiveness, cost, schedule, and regulatory acceptance.

Our role is to bridge the gap between investigation results and real-world implementation.

Depending on site conditions and project goals, CRB’s remediation services may include:

Remedial Action Plan (RAP) Preparation: Development of regulator-ready cleanup strategies tailored to site conditions and regulatory frameworks.

Remedial Investigation & Feasibility Studies (RI/FS): Detailed evaluations to support remedy selection and regulatory decision-making.

Design & Operation of Remedial Systems: Engineering and oversight of systems such as groundwater extraction and treatment, soil vapor mitigation, and in-situ treatment systems.

Groundwater Recovery & Treatment: Systems designed for plume control, mass removal, or long-term containment.

Sub-Slab Mitigation & Vapor Control: Mitigation systems to manage vapor intrusion risk in occupied buildings.

Bioremediation: Microbial and geochemical treatment strategies for petroleum hydrocarbons, solvents, and certain metals.

Dewatering & Water Management: Solutions for construction dewatering and contaminated groundwater control.

Long-Term Monitoring & System Optimization: Performance monitoring, data evaluation, and system adjustments to meet cleanup goals efficiently.

Every program is custom-designed to reflect site conditions, cleanup objectives, regulatory requirements, and business constraints.

From Investigation to Implementation

Many clients come to CRB after a Phase II ESA confirms contamination. CRB’s expertise helps bridge the gap between knowing a problem exists and solving it effectively.

We help clients:

Delineate the extent of contamination

Evaluate exposure pathways and risk

Select appropriate remedial technologies

Design and implement treatment systems

Coordinate with regulatory agencies and stakeholders

Document progress and demonstrate cleanup or control

Whether a site requires engineered systems, passive remediation, monitored natural attenuation, or a combined approach, CRB has the experience and technical depth to deliver defensible results.

[The CRB Remediation Process]

Site Evaluation & Remediation Planning

We review investigation data, site conditions, and regulatory context to define objectives.

Remedy Selection & Design

CRB crafts remedial system designs and coordinates with permitting agencies to align expectations and approvals.

Implementation & System Operation

We oversee system installation and monitor performance to ensure cleanup goals are met.

Monitoring, Optimization & Closure

We track performance, refine systems, and support regulatory closure or long-term management.

Frequently Asked Questions

  • Environmental remediation is the process of removing, treating, or managing contamination in soil, groundwater, soil vapor, or structures to protect human health, meet regulatory requirements, and restore property for safe use or redevelopment.

  • Corrective action refers to regulatory-driven cleanup required by environmental agencies when contamination is discovered, often at facilities regulated under programs such as RCRA, UST, or state cleanup programs. It involves investigation, cleanup planning, and implementation of approved remediation measures.

  • Remediation is typically required when environmental investigations (such as a Phase II ESA) confirm contamination that exceeds regulatory standards or poses unacceptable risk to human health or the environment. It is also often required before redevelopment, property sale, or regulatory closure.

  • CRB provides remediation services for:

    • Petroleum hydrocarbons

    • Chlorinated solvents

    • Metals

    • Soil vapor and methane

    • Groundwater contamination

    • Underground storage tank (UST) releases

    • Industrial and commercial site contamination

  • CRB evaluates:

    • Type and extent of contamination

    • Site geology and hydrogeology

    • Regulatory cleanup requirements

    • Property use and redevelopment plans

    • Cost and schedule constraints

    Based on these factors, we design practical, cost-effective remediation strategies tailored to your site.

  • In many cases, yes. Lenders, buyers, and regulators often require contamination to be addressed or managed before a property can be sold, financed, or redeveloped. CRB helps clients integrate remediation into transaction and development strategies.

  • Yes. CRB provides end-to-end support, from Phase II investigations through remediation design, implementation, and regulatory closure.
