Contaminated Land and Remediation new

Contaminated Land Assessment and Remediation Services in Saudi Arabia

Understand contamination. Plan effective remediation. Prepare your site for its next use.

ETLCO provides contaminated land assessment, remediation planning and site rehabilitation support to help industrial operators, developers and landowners manage environmental risks and make informed decisions.

Our services address soil and groundwater contamination, historical industrial impacts and the rehabilitation of degraded or contaminated sites. We develop project-specific studies and plans to support the applicable requirements of the National Center for Environmental Compliance (NCEC) and the Royal Commission for Jubail and Yanbu (RC), according to the site’s location and regulatory jurisdiction.

From initial site investigations to remediation verification, ETLCO helps turn environmental findings into practical actions for site management, redevelopment and closure.

Identify Environmental Risks Before They Affect Your Project

Contamination may remain undetected beneath operating facilities, former industrial sites, storage areas or undeveloped land. Understanding its nature and extent helps your team plan appropriate controls and avoid unexpected complications during excavation, construction or property redevelopment.

Our services help you:

• Identify potential contamination sources and affected areas.

• Assess soil and groundwater conditions.

• Understand potential risks to people and the environment.

• Evaluate remediation options and implementation priorities.

• Establish clear rehabilitation objectives.

• Prepare documentation for review by the relevant authority.

• Verify remediation outcomes against agreed objectives.

Our Contaminated Land and Remediation Services

1. Site Characterization and Preliminary Assessment

We begin by reviewing the site’s history, current activities and environmental setting to identify areas requiring further investigation.

The assessment may include:

• Historical and current land uses.

• Previous industrial processes and storage activities.

• Chemical, fuel and waste handling areas.

• Available records of spills, leaks and environmental incidents.

• Existing monitoring data and previous investigation reports.

• Nearby communities, water resources and other sensitive receptors.

• Site drainage, ground conditions and potential contamination pathways.

This review provides the basis for a focused investigation strategy.

2. Phase I Environmental Site Assessment

A Phase I Environmental Site Assessment evaluates available information and site observations to identify potential environmental concerns.

Depending on the agreed scope, activities may include document reviews, site reconnaissance and discussions with site personnel.

The assessment helps identify whether further investigation is warranted. It does not normally include intrusive sampling and cannot, on its own, confirm that a site is free from contamination.

3. Phase II Environmental Site Assessment

Where potential contamination is identified, ETLCO develops a targeted investigation to assess site conditions through sampling and laboratory analysis.

Depending on the site and investigation objectives, the scope may include:

• Soil sampling at selected locations and depths.

• Groundwater investigation and sampling, where relevant.

• Sampling of sediment, surface water or other affected materials.

• Analysis of contaminants associated with historical or current activities.

• Evaluation of the distribution and extent of identified contamination.

• Identification of data gaps requiring further investigation.

Analytical parameters may include petroleum hydrocarbons, volatile and semi-volatile organic compounds, metals and other site-specific contaminants.

4. Environmental Risk Assessment

The presence of a contaminant does not, by itself, define the level of risk. Risk assessment considers how contaminants could reach people or environmental receptors under current or proposed site conditions.

We evaluate the relationship between:

• Sources: Where contamination originates or remains.

• Pathways: How contaminants may move or cause exposure.

• Receptors: People, groundwater, ecosystems or other potentially affected resources.

This assessment helps prioritize actions and develop remediation objectives appropriate to the site’s intended use and applicable regulatory requirements.

5. Remediation Feasibility Studies and Technology Selection

ETLCO evaluates potential remediation approaches to help clients select a practical strategy.

Depending on the contamination and site conditions, options considered may include excavation and off-site treatment or disposal, containment, biological treatment, physical or chemical treatment, and groundwater management.

Options are assessed against factors such as:

• Contaminant type, concentration and distribution.

• Soil characteristics and groundwater conditions.

• Expected treatment effectiveness.

• Site access and operational constraints.

• Implementation time and indicative costs.

• Waste generation and disposal requirements.

• Monitoring needs and long-term management obligations.

The preferred approach is developed from site evidence and project objectives, subject to the applicable authority’s requirements.

6. Customized Soil and Groundwater Remediation Plans

We prepare remediation plans that translate investigation findings into a defined scope of work.

Plans may address:

• Remediation objectives and assessment criteria.

• Areas and materials requiring treatment or management.

• Proposed techniques and implementation sequence.

• Excavation, segregation and temporary storage arrangements.

• Measures to prevent contaminant migration during works.

• Management of contaminated water and excavated materials.

• Environmental monitoring and verification sampling.

• Responsibilities, reporting and contingency actions.

Clear planning helps clients and remediation contractors understand the required outcomes and how those outcomes will be evaluated.

7. Rehabilitation of Degraded or Contaminated Sites

ETLCO develops rehabilitation plans for sites affected by contamination or environmental degradation, supporting submissions to NCEC or the Royal Commission where applicable.

The scope is tailored to the site’s condition, intended future use and identified environmental risks.

Rehabilitation planning may include:

• Removal or management of contamination sources.

• Treatment or management of affected soil and groundwater.

• Restoration of disturbed ground and suitable surface conditions.

• Erosion control and drainage improvements, where needed.

• Revegetation or habitat restoration measures, where appropriate.

• Post-rehabilitation monitoring and maintenance.

• Documentation of remaining restrictions or management requirements.

The objective is to establish a site condition suitable for the agreed use, with environmental risks appropriately managed.

8. Remediation Monitoring and Verification

ETLCO provides monitoring and verification support to assess whether completed remediation works meet the agreed objectives.

Depending on the project, this may include:

• Field observations during remediation activities.

• Verification sampling of treated areas or excavation boundaries.

• Laboratory analysis of soil, groundwater and other relevant samples.

• Review of treatment performance and material management records.

• Identification of areas requiring additional action.

• Preparation of verification and completion reports.

Verification findings provide evidence for project closeout and authority review. Regulatory closure remains subject to acceptance by the relevant authority.

Support for NCEC and Royal Commission Requirements

ETLCO structures assessments and remediation documentation around the requirements applicable to each site, including relevant NCEC requirements, Royal Commission Environmental Regulations and project-specific permit conditions.

Our support may include reviewing authority correspondence, identifying required studies, preparing technical submissions and responding to review comments within the agreed scope.

Remediation criteria and monitoring requirements are selected according to the applicable regulatory framework and site conditions. Where site-specific objectives are proposed, these are documented for discussion and acceptance by the relevant authority.

What Your Project Receives

Depending on the agreed scope, deliverables may include:

• Preliminary site assessment and investigation reports.

• Phase I and Phase II Environmental Site Assessments.

• Sampling plans, analytical results and contamination maps.

• Environmental risk assessments.

• Remediation feasibility studies.

• Soil and groundwater remediation plans.

• Degraded or contaminated site rehabilitation plans.
