Oil, gas and industrial sites can present soil-quality questions related to petroleum hydrocarbons, metals, process chemicals, historical releases and site operations.

PBR Laboratories provides analytical soil testing support from Edmonton for industrial, energy, remediation and environmental projects throughout Alberta, Western Canada and Canada.

Depending on the site history and investigation objective, testing may include:

  • petroleum hydrocarbons;
  • metals;
  • soil chemistry;
  • glycols and alcohols where applicable;
  • environmental microbiology;
  • related groundwater or environmental water testing.

The correct analytical program depends on the site activity, suspected release, process materials, sample location, depth and decision the results need to support.

What Is Industrial Soil Testing?

Industrial soil testing measures selected contaminants and soil characteristics where current or historical operations may have affected site conditions.

Testing may support questions such as:

  • Has a fuel or process-material release affected soil?
  • Are petroleum hydrocarbons elevated?
  • Are selected metals present above applicable criteria?
  • Could process chemicals or industrial materials be relevant?
  • Is additional horizontal or vertical delineation needed?
  • Could groundwater also be affected?
  • What laboratory data are needed before remediation or reclamation decisions?

A laboratory result applies to the submitted sample and should be interpreted with the site history, sampling plan and applicable project criteria.

When Should Oil, Gas & Industrial Sites Be Tested?

After a Spill or Release

Testing can help characterize soil potentially affected by fuel, oil or other industrial materials.

Around Storage and Transfer Areas

Tank farms, fuel storage, loading areas and transfer points may require investigation where releases are suspected.

At Processing or Manufacturing Sites

Process areas can involve different chemicals and metals depending on the operation.

During Environmental Site Assessment

Historical industrial use may indicate a need for targeted soil testing.

Before Remediation

Analytical results can help characterize contaminants and affected areas before remediation decisions.

After Remediation

Follow-up testing may help evaluate how measured concentrations have changed at sampled locations.

Petroleum Hydrocarbon Testing for Industrial Sites

Petroleum hydrocarbons are often a key concern at energy and industrial sites where fuels, oils or petroleum products are stored or handled.

PBR’s soil service architecture includes petroleum hydrocarbon testing for applicable soil matrices.

Testing can support:

spill investigation → site characterization → delineation → remediation → follow-up monitoring

What does an elevated hydrocarbon result mean?

It means the measured concentration in the submitted sample is above the comparison value used for the project.

It does not automatically determine:

  • the source;
  • the full extent;
  • the depth of impact;
  • whether groundwater is affected;
  • whether remediation is complete.

Metals Testing for Industrial Sites

Industrial operations may create reasons to investigate selected metals depending on:

  • process history;
  • raw materials;
  • waste handling;
  • storage areas;
  • previous site results;
  • fill material.

The element list should be based on the actual operation rather than using the same broad panel at every site.

Does detecting a metal mean industrial contamination occurred?

Not necessarily.

Some elements occur naturally in soil, so interpretation should consider:

  • background conditions;
  • geology;
  • site history;
  • land use;
  • applicable criteria.

Soil Chemistry for Industrial Investigations

Soil chemistry may provide useful context alongside contaminant testing.

Depending on the project, PBR can support parameters such as:

  • pH;
  • electrical conductivity;
  • alkalinity;
  • major anions and cations;
  • total organic carbon;
  • other applicable soil chemistry parameters.

These results can help characterize site conditions and support interpretation of contamination data.

Glycols, Alcohols & Other Process-Related Concerns

PBR’s legacy soil chemistry service information identifies glycols and alcohols among the soil analyses offered.

For industrial projects, these may be relevant where site history or process use indicates a potential concern.

The exact target compound, method and current matrix scope should be confirmed before sample submission.

PBR should not imply that every industrial chemical can be analyzed under a single generic soil panel.

Environmental Microbiology for Industrial Sites

Microbiology may be useful where biological processes are relevant to the investigation.

PBR’s documented environmental microbiology capabilities include areas such as:

  • hydrocarbon-utilizing bacteria;
  • sulfate-reducing bacteria;
  • iron-related bacteria;
  • heterotrophic aerobic bacteria;
  • other applicable environmental microbial groups.

When can microbiology add value?

It may provide complementary information where:

  • bioremediation is being considered;
  • hydrocarbon degradation is part of the project;
  • industrial microbial activity is relevant.

Microbiology does not replace contaminant chemistry.

Industrial Soil Testing & Groundwater

Soil and groundwater may need to be evaluated together when contaminants could migrate below the soil zone.

Relevant factors include:

  • contaminant properties;
  • release depth;
  • soil permeability;
  • groundwater elevation;
  • site geology.

Where groundwater impact is plausible, environmental water testing may be appropriate alongside soil testing.

Site History Should Determine the Testing Panel

A refinery, fabrication shop, fuel-storage site and processing facility should not automatically receive the same analytical panel.

A better framework is:

operation history → materials handled → potential release mechanisms → likely contaminants → sampling locations → laboratory testing

This approach reduces unnecessary testing and helps ensure important analytes are not overlooked.

Common Industrial Source Areas to Investigate

Depending on the site, sampling may focus on areas such as:

  • storage tanks;
  • loading and unloading areas;
  • process equipment;
  • maintenance areas;
  • waste-storage zones;
  • historical spill locations;
  • drainage pathways;
  • former structures;
  • imported fill.

The field investigation should determine the actual sampling locations.

PBR’s role is to support the laboratory side with appropriate sample requirements and analytical options.

Soil Sampling at Industrial Sites

Industrial contamination can be localized.

Sampling design may need to consider:

  • source areas;
  • downgradient or migration pathways;
  • sample depth;
  • horizontal coverage;
  • vertical coverage;
  • background locations;
  • soil type;
  • previous analytical results.

PBR’s decision framework emphasizes representative sampling and correct handling when analytical results support site-level decisions.

Ask PBR about containers, sample quantity and handling requirements before field sampling.

Grab Samples vs Composite Samples

Grab Samples

A grab sample represents one location or depth and can be useful for targeted source-area investigation.

Composite Samples

A composite combines material from several locations.

This can provide an average but may also dilute localized contamination.

For industrial sites, compositing should therefore be used only when it aligns with the project objective.

Delineating Industrial Soil Contamination

When contaminants are identified, the next question is often:

How far does the impact extend?

Additional sampling may be needed to evaluate:

Horizontal extent

How far contamination extends away from the suspected source.

Vertical extent

How deep contamination extends below ground.

Laboratory data provide the measured concentrations. The environmental investigation determines how those values are used to define the affected area.

Supporting Remediation & Reclamation

Analytical soil testing can support multiple stages of industrial remediation.

A typical workflow:

Historical review / suspected release

Initial characterization

Delineation

Remediation or reclamation activity

Follow-up sampling

Analytical review

Depending on the site, relevant testing may include hydrocarbons, metals, chemistry and microbiology.

What Happens if Results Stay Elevated After Remediation?

An elevated follow-up result may require review of:

  • sample location;
  • remediation coverage;
  • contamination depth;
  • residual source;
  • heterogeneous soil;
  • previous data;
  • groundwater;
  • sampling design.

The next step should be chosen around a defined question rather than simply repeating the same sample.

Common Mistakes in Industrial Soil Testing

  • Using a Generic Contaminant Panel
    Testing should reflect the materials and processes used at the site.
  • Sampling Only Easy-to-Access Locations
    Convenient sampling may miss source areas.
  • Ignoring Depth
    Industrial contaminants can migrate below surface soil.
  • Overusing Composite Samples
    Composites can mask localized elevated concentrations.
  • Treating One Clean Result as Site-Wide Evidence
    A result represents the submitted sample, not the entire industrial property.
  • Ignoring Groundwater
    Subsurface migration may make groundwater relevant to the investigation.
  • Retesting Without Revisiting the Investigation
    Unexpected results should trigger review of the site and sampling strategy.
