Environmental consultants need laboratory data that answers specific site questions—not simply a long list of analytical results.

PBR Laboratories supports environmental consultants and project teams with soil testing for site characterization, suspected contamination, environmental investigation, remediation and reclamation projects throughout Alberta, Western Canada and Canada.

Depending on site history and project objectives, testing may include:

  • soil chemistry;
  • petroleum hydrocarbons;
  • metals;
  • environmental microbiology;
  • pH and electrical conductivity;
  • major ions;
  • total organic carbon;
  • selected industrial contaminants;
  • related environmental water testing.

The analytical program should be built around:

site history → potential contaminants → sampling plan → laboratory analysis → applicable criteria → project decision

Laboratory Support for Environmental Site Investigations

Environmental soil testing is most useful when the analytical scope reflects what may actually have occurred at the site.

Before selecting a test panel, consider:

  • historical property use;
  • current operations;
  • known spills or releases;
  • storage areas;
  • waste-handling areas;
  • imported fill;
  • previous environmental results;
  • neighbouring activities;
  • potential migration pathways.

This information helps determine what should be analyzed and where samples should be collected.

What Can PBR Test in Environmental Soil?

Soil Chemistry

PBR's documented soil chemistry capabilities include parameters such as:

  • pH;
  • alkalinity;
  • electrical conductivity;
  • major anions and cations;
  • total organic carbon;
  • sodium adsorption ratio;
  • cation exchange capacity;
  • selected nutrient-related parameters.

Soil chemistry can contribute to baseline characterization, environmental assessment and interpretation of site conditions.

Petroleum Hydrocarbon Testing

Petroleum hydrocarbons may be relevant where site history includes:

  • fuel storage;
  • petroleum handling;
  • equipment operations;
  • industrial activities;
  • spills or releases.

PBR's existing soil services document petroleum hydrocarbon testing for applicable soil matrices.

Results may support:

initial investigation → characterization → delineation → remediation → follow-up monitoring

Metals Testing

Metals testing may be appropriate where historical or current site activities create reasons to investigate selected elemental concentrations.

The required metals list should be based on:

  • site history;
  • industrial process;
  • suspected source;
  • previous results;
  • applicable project criteria.

Detection alone does not establish that a site is contaminated because some elements occur naturally in soil.

Environmental Soil Microbiology

Selected environmental investigations may also benefit from microbiological testing.

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

  • heterotrophic aerobic bacteria;
  • hydrocarbon-utilizing bacteria;
  • sulfate-reducing bacteria;
  • iron-related bacteria;
  • nitrifying and denitrifying bacteria;
  • other environmental microbial groups for applicable matrices.

Microbiology may provide complementary information where biodegradation or biological remediation is part of the project.

It does not replace contaminant chemistry.

What Should Be Tested During an Environmental Site Investigation?

There is no universal soil-testing panel for every site.

Testing should begin with the potential contaminant sources.

  • Petroleum-related site history
    Consider relevant petroleum hydrocarbon testing and associated site chemistry.
  • Metal-related industrial activity
    Consider the metals associated with the historical or current process.
  • Chemical processing or storage
    Consider the substances handled at the site and appropriate analytical parameters.
  • Unknown or imported fill
    The analytical approach should reflect available information about the fill and project requirements.
  • Remediation site
    Testing should reflect the contaminant already identified and the purpose of follow-up sampling.

Baseline Soil Characterization

Baseline testing can provide analytical information about soil conditions before:

  • new operations;
  • development;
  • construction;
  • industrial activity;
  • other site changes.

Baseline information may later help distinguish existing conditions from potential subsequent impacts.

The analytical panel should reflect the activities and environmental questions relevant to the site rather than using a generic suite without a defined purpose.

Investigating Suspected Soil Contamination

When contamination is suspected, the investigation usually needs to answer more than:

Was something detected?

More useful questions include:

  • What was measured?
  • At what concentration?
  • Where was the sample collected?
  • At what depth?
  • How does the result compare with applicable criteria?
  • Are nearby locations also affected?
  • Could another environmental medium be affected?
  • Is additional investigation required?

This is where laboratory testing becomes part of the broader environmental decision process.

Supporting Contamination Delineation

When a contaminant is identified, additional samples may be required to determine its distribution.

Horizontal Delineation

Additional locations can help evaluate how far an impact extends away from the suspected source.

Vertical Delineation

Samples collected at different depths can help evaluate how far an impact extends below ground.

The laboratory provides the analytical values.

The broader environmental investigation determines how those results are used to characterize the site.

Soil Testing & Groundwater Investigation

Soil and groundwater questions are often interconnected.

Depending on:

  • contaminant characteristics;
  • site geology;
  • soil permeability;
  • depth of contamination;
  • groundwater elevation;

an environmental investigation may need to consider groundwater in addition to soil.

PBR provides environmental water testing for applicable groundwater and surface-water matrices.

Supporting Remediation Decisions

Laboratory testing may be used throughout a remediation project.

A typical workflow can include:

Site history

Initial sampling

Contaminant identification

Delineation

Remediation

Follow-up sampling

Analytical review

Laboratory results provide evidence about the samples analyzed, but one result should not be treated as proof of conditions across the entire site.

Soil Sampling for Environmental Consultants

The quality of the laboratory data depends partly on the quality of the sample.

Sampling plans may need to consider:

  • source locations;
  • background locations;
  • sample depth;
  • horizontal coverage;
  • vertical coverage;
  • soil heterogeneity;
  • suspected contaminant distribution;
  • containers;
  • preservation;
  • transportation;
  • chain of custody.

PBR's decision framework identifies representative sampling and proper sample handling as important to producing useful analytical information.

Ask PBR about sample requirements before field mobilization.

Grab Samples vs Composite Samples

The correct approach depends on the investigation.

Grab samples

Represent a defined location or depth and may be particularly useful when localized contamination is being investigated.

Composite samples

Combine material from several locations and may provide an average representation.

However, compositing can also dilute a localized elevated concentration.

Environmental consultants should select the sampling approach based on the decision the resulting data must support.

Common Mistakes in Environmental Soil Testing

  • Selecting Tests Before Reviewing Site History
    This can produce irrelevant analysis while missing the actual contaminants of concern.
  • Collecting Too Few Samples
    Site heterogeneity can make limited sampling difficult to interpret.
  • Ignoring Depth
    Contamination may vary substantially with depth.
  • Automatically Compositing Samples
    A composite can conceal localized impacts.
  • Treating Detection as Automatic Failure
    Detected concentrations must be evaluated against the appropriate project criteria and context.
  • Treating One Clean Result as Site-Wide Evidence
    A result represents the submitted sample, not every location at the property.
  • Ignoring Other Environmental Media
    Groundwater or surface water may need consideration depending on the site.

What Should You Do After an Elevated Soil Result?

An elevated result should trigger a decision process, not an automatic conclusion.

Consider:

  • Confirm the applicable comparison criteria.
  • Review sample location and depth.
  • Compare surrounding results.
  • Review site history and potential sources.
  • Determine whether additional horizontal or vertical sampling is needed.
  • Consider groundwater or other environmental media where relevant.
  • Determine whether additional characterization or remediation-related testing is appropriate.
