Microbiological testing is crucial for detecting and quantifying microbial contaminants that may present health risks in water, soil, or air samples. This testing encompasses a range of parameters, including total coliforms, E. coli, fecal coliforms, total plate count, Legionella, and pathogenic bacteria.

By identifying these potential hazards, we help ensure the safety and quality of the environment and safeguard public health. Our microbiological testing services are essential in various industries, including environmental monitoring, water treatment, public health, and food safety.

Contaminated Land Assessment and Site Rehabilitation in Saudi Arabia

Understand your site. Assess environmental risks. Plan the right path to recovery.

Environmental Testing and Laboratories Company (ETLCO) provides contaminated land assessments, soil and groundwater remediation planning, and rehabilitation plans for degraded or contaminated sites across Saudi Arabia.

We help industrial operators, developers, and landowners understand site conditions, evaluate environmental risks, and make informed decisions about land acquisition, redevelopment, remediation, and closure.

Whether you need to investigate suspected contamination or prepare a site rehabilitation plan for submission to the National Center for Environmental Compliance (NCEC), our team develops a scope tailored to your site, project objectives, and applicable environmental requirements.

Site Characterization and Preliminary Assessment

Effective site management begins with understanding the land’s history and current condition. ETLCO reviews available information and identifies potential contamination sources and areas requiring further investigation.

Our scope may include:

• Reviewing historical and current land use.
• Conducting site inspections to identify signs of contamination and environmental degradation.
• Identifying potential sources, including storage areas, spills, leaks, and waste disposal activities.
• Reviewing available soil, groundwater, and surrounding land-use information.
• Developing an initial understanding of how contaminants could move and affect people or the environment.

Phase I Environmental Site Assessment

Phase I ESA

A Phase I Environmental Site Assessment helps identify potential environmental concerns before land acquisition, redevelopment, or further investigation.

ETLCO reviews available records, inspects the site, and gathers relevant information to evaluate whether past or current activities may have affected its environmental condition.

The assessment typically includes:

• Review of available historical and environmental records.
• Site reconnaissance and visual inspection.
• Discussions with relevant site representatives, where appropriate.
• Identification of potential contamination concerns and information gaps.
• A report outlining findings and recommendations for further investigation.

Phase I assessments generally do not include soil or groundwater sampling.

Phase II Environmental Site Assessment

Phase II ESA

Where potential contamination requires investigation, ETLCO develops a targeted sampling and testing program to assess its presence, nature, and extent.

Our scope may include:

• Preparing a sampling plan focused on areas of concern.
• Collecting soil and groundwater samples, as required.
• Testing for contaminants associated with the site’s activities and history.
• Interpreting results against criteria applicable to the site and its intended use.
• Identifying the need for further investigation, risk assessment, or remediation planning.

The investigation provides a clearer basis for deciding what action is needed and where to focus it.

Environmental and Human Health Risk Assessment

We assess the potential risks associated with identified contaminants, considering their concentrations, exposure pathways, and the site’s current and proposed uses.

This assessment helps determine remediation priorities and objectives, with consideration for:

• Site workers and future occupants.
• Neighboring communities and other potentially affected people.
• Soil and groundwater resources.
• Surrounding ecosystems and sensitive environmental features.
• The potential movement of contaminants beyond the affected area.

Our findings support proportionate, site-specific decisions about remediation and risk management.

Remediation Feasibility Studies and Technology Selection

Choose a remediation approach that fits your site and project objectives.

ETLCO evaluates remediation options to help clients understand their technical suitability, practical requirements, and expected performance.

We consider:

• Contaminant types, concentrations, and distribution.
• Soil properties and groundwater conditions.
• Current and future land use.
• Expected treatment effectiveness and duration.
• Cost, operational requirements, and monitoring needs.
• Environmental impacts and the management of treatment residues.

Depending on site conditions, options assessed may include excavation and removal, in-situ treatment, biological treatment, physical or chemical treatment, containment, or measures to control contaminant migration.

Soil and Groundwater Remediation Plans

We develop site-specific remediation plans that translate assessment findings into clear, actionable requirements.

A remediation plan may include:

• A description of site conditions and the nature and extent of contamination.
• Remediation objectives and verification criteria.
• Recommended treatment methods and the reasons for their selection.
• Proposed implementation stages, priorities, and schedules.
• Measures to control contaminant migration during the works.
• Requirements for handling contaminated soil, water, and treatment residues.
• Sampling and verification programs to assess results.
• Follow-up monitoring and reporting requirements, where necessary.

Our plans help clients define the work required and establish how its effectiveness will be evaluated.

Rehabilitation Plans for Degraded or Contaminated Sites

Preparation for Submission to NCEC

ETLCO prepares rehabilitation plans for degraded or contaminated sites for submission to the National Center for Environmental Compliance (NCEC), taking into account applicable site requirements and comments issued by the Center.

These plans address the effects of previous activities, identify measures to control pollution sources, and establish a route toward restoring the site to a condition appropriate for its intended use.

Depending on the project, our services may include:

• Reviewing site conditions, previous studies, and analytical results.
• Reviewing NCEC observations and site-specific requirements.
• Defining rehabilitation and remediation activities and their priorities.
• Preparing a plan covering objectives, proposed methods, schedules, and implementation responsibilities.
• Establishing requirements for managing waste, contaminated soil, and materials generated during the works.
• Developing environmental monitoring and verification programs.
• Preparing technical documentation to support completion reporting and environmental closure requests, where applicable.
• Supporting plan submission and responses to technical comments during the review process.

Acceptance of plans and closure of observations remain subject to NCEC review and fulfillment of its requirements.

When Do You Need a Site Assessment or Rehabilitation Plan?

Our services support clients at key stages of a property or facility’s lifecycle:

• Before purchasing land or an industrial property: Understand potential environmental concerns before committing.
• Before redevelopment or a change in land use: Assess whether site conditions are suitable for the proposed use.
• Following a spill or leak: Investigate potential impacts on soil and groundwater.
• During facility closure or decommissioning: Identify remediation and rehabilitation needs.
• When contamination or degradation is suspected: Establish the cause, extent, and appropriate next steps.
• When NCEC requests a rehabilitation plan: Prepare a site-specific response supported by technical assessment.
