Remediation and reclamation projects need laboratory data that helps project teams understand what contamination is present, where it occurs, how conditions change during treatment and what follow-up testing may be needed.

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

Depending on the site and contaminants of concern, testing may include:

  • petroleum hydrocarbons;
  • metals;
  • soil chemistry;
  • salinity and related parameters;
  • nutrients;
  • environmental microbiology;
  • related groundwater or environmental water testing.

PBR’s environmental testing framework specifically identifies soil testing for metals, hydrocarbons, BTEX, salinity, nutrients, pH and related parameters as supporting site assessment, remediation, reclamation, disposal and land-use decisions.

How Does Soil Testing Support Remediation & Reclamation?

Laboratory testing can support multiple stages of a remediation or reclamation project.

A typical decision pathway is:

Initial characterization

Identify contaminants and affected areas

Define the remediation or reclamation objective

Implement treatment or soil-management activities

Collect follow-up samples

Compare results with applicable project criteria

Determine the next project step

Testing should be selected around the contaminant, site conditions and decision being made rather than using the same analytical panel for every remediation project.

Initial Site Characterization

Before remediation begins, soil testing can help establish:

  • which contaminants are present;
  • measured concentrations at sampled locations;
  • relevant soil chemistry;
  • whether impacts vary by depth or location;
  • whether groundwater or another environmental medium may also need investigation.

The initial analytical program should be driven by site history and suspected contaminant sources.

Petroleum Hydrocarbon Testing During Remediation

Petroleum hydrocarbon testing may be relevant for sites affected by:

  • fuel releases;
  • petroleum storage;
  • oil handling;
  • industrial operations;
  • historical energy-sector activity.

PBR’s environmental framework identifies hydrocarbons and BTEX as supporting environmental investigations, source characterization, remediation planning and confirmation of cleanup progress.

What can hydrocarbon results help determine?

Results may support:

  • initial characterization;
  • comparison between affected areas;
  • delineation;
  • evaluation of changes over time;
  • follow-up after remediation activity.

A reduction at one sampled location does not automatically prove the entire site has reached the project objective.

Metals Testing During Remediation

Where metals are contaminants of concern, laboratory analysis may be used to characterize selected elements before and after remediation or soil-management activities.

The required element list should reflect:

  • site history;
  • identified contaminants;
  • project requirements;
  • previous analytical results.

Do metals behave the same way as petroleum hydrocarbons?

No.

Different contaminants can require different remediation and interpretation approaches.

PBR’s role is to provide analytical data supporting the project team’s decision rather than prescribe a universal remediation strategy.

Soil Chemistry for Reclamation Projects

Reclamation projects may require information beyond contaminant concentrations.

PBR’s environmental framework identifies soil testing for parameters such as:

  • salinity;
  • nutrients;
  • pH;
  • related soil chemistry.

Depending on the project, relevant analytical parameters may include:

  • pH;
  • electrical conductivity;
  • sodium adsorption ratio;
  • nutrient-related parameters;
  • organic carbon;
  • cation exchange capacity;
  • major ions.

These measurements can help characterize soil conditions during reclamation and compare different locations or time points.

Environmental Microbiology & Bioremediation

Selected remediation programs may involve biological processes.

PBR’s service catalogue documents environmental microbiology capabilities for water and soil matrices including:

  • iron-related bacteria;
  • sulfate-reducing bacteria;
  • slime-forming bacteria;
  • acid-producing bacteria;
  • nitrifying bacteria;
  • denitrifying bacteria.

PBR’s broader environmental microbiology framework also supports specialized microbial investigations where relevant.

Can microbiology prove bioremediation is working?

Not by itself.

Microbial data may provide useful complementary information, but remediation performance should also consider:

  • contaminant chemistry;
  • site conditions;
  • oxygen;
  • moisture;
  • pH;
  • nutrients;
  • temperature;
  • changes in contaminant concentration over time.

Monitoring Remediation Progress

One of the most important uses of laboratory testing is comparing conditions over time.

For meaningful trend comparison, try to keep the following consistent where appropriate:

  • sample locations;
  • sampling depth;
  • sampling method;
  • analytical method;
  • units;
  • sample handling;
  • comparison criteria.

Changing several factors between sampling events can make trend interpretation more difficult.

What Does a Lower Follow-Up Result Mean?

A lower result indicates that the measured concentration in that submitted sample is lower than the comparison result.

It does not automatically prove that:

  • all contaminated soil has been addressed;
  • every area of the site shows the same reduction;
  • the contaminant source is gone;
  • groundwater is unaffected;
  • remediation is complete.

The result must be considered within the broader sampling and remediation program.

PBR’s decision framework explicitly notes that laboratory results apply to the submitted sample and that sampling design affects how confidently a result can represent a site.

What Happens if Results Remain Elevated?

An elevated result after remediation activity should trigger a review of the project rather than an automatic repeat of the same test.

Questions may include:

  • Was the sample collected from an area that was fully treated?
  • Is residual contamination present at depth?
  • Is contamination unevenly distributed?
  • Could another source still be present?
  • Did the sampling location change?
  • Is additional horizontal or vertical delineation needed?
  • Could groundwater or another environmental medium be involved?

The next analytical step should address a defined project question.

Confirmation & Follow-Up Sampling

Follow-up sampling may be used after:

  • excavation;
  • soil treatment;
  • removal of impacted material;
  • bioremediation;
  • other remediation activities.

The sampling approach should be designed around what the project team needs to demonstrate or investigate.

PBR’s framework warns against common workflow risks including too few samples, non-representative sampling, compositing that dilutes localized contamination and using results without considering the applicable decision rule.

Grab Samples vs Composite Samples in Remediation Projects

Grab Samples

Grab samples represent specific locations or depths and may be useful where the project needs to assess localized conditions.

Composite Samples

Composite samples provide an average across several increments.

They can reduce analytical cost, but PBR’s framework notes that compositing can dilute localized contamination.

Composite sampling should therefore only be used when it supports the specific remediation or reclamation decision.

Soil & Groundwater During Remediation

Contamination may involve both soil and groundwater.

Whether groundwater testing is relevant depends on:

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

PBR’s environmental framework identifies environmental water testing for chemistry, metals, nutrients, hydrocarbons and microbiology as supporting source investigation, impact monitoring and remediation decisions.

Reclamation Soil Testing

Reclamation differs from contamination remediation because the analytical question may involve broader soil condition and land-use suitability, not only contaminant removal.

Relevant soil testing may include:

  • pH;
  • electrical conductivity;
  • salinity-related parameters;
  • sodium adsorption ratio;
  • nutrient characteristics;
  • organic carbon;
  • contaminants where relevant.

The appropriate panel depends on the project objective and applicable reclamation criteria.

Remediation vs Reclamation

What is the difference between remediation and reclamation?

Remediation generally focuses on addressing contamination or environmental impacts.

Reclamation focuses more broadly on restoring land conditions for the intended land use or project objective.

A project can involve both.

Laboratory soil testing may therefore shift from:

contaminant characterization

to:

contaminant follow-up + soil-condition assessment

as the project progresses.

Common Mistakes in Remediation Soil Testing

  • Testing Only After Remediation
    Without adequate pre-remediation data, it may be more difficult to understand how conditions changed.
  • Moving Sample Locations Without Documentation
    Trend comparisons are weaker if location or depth changes without context.
  • Relying on Too Few Samples
    Localized residual contamination may be missed.
  • Treating a Lower Result as Automatic Completion
    A lower concentration at one location does not define site-wide conditions.
  • Overusing Composite Samples
    Composite samples can mask localized residual contamination.
  • Ignoring Related Environmental Media
    Groundwater or surface water may remain relevant.
  • Using a Different Method Without Considering Comparability
    Results from different methods may not always be directly comparable.

  • land redevelopment;
  • reclamation;
  • environmental consulting.

Remediation Soil Testing Across Western Canada

PBR supports environmental consultants, industrial operators and remediation teams throughout Western Canada with soil and environmental water testing relevant to remediation and reclamation projects.

The analytical program should reflect the contaminant, site and project objective rather than relying on a generic cleanup-testing package.

Remediation & Reclamation Soil Testing Across Canada

PBR supports Canadian projects requiring analytical laboratory data for site characterization, remediation, reclamation and follow-up monitoring.

The PBR approach is:

define the decision → select the relevant matrix and analytes → collect representative samples → review analytical results → determine the appropriate project next step

That follows PBR’s decision-focused positioning.

Frequently Asked Questions

What soil testing is used during remediation?

Depending on the site and contaminant, testing may include petroleum hydrocarbons, metals, soil chemistry, salinity, nutrients and environmental microbiology.

Can PBR support soil testing before and after remediation?

Yes. PBR’s environmental testing framework identifies soil, hydrocarbons and related parameters as supporting site assessment, remediation, reclamation and confirmation of cleanup progress.

What does a lower contaminant result after remediation mean?

It means the submitted follow-up sample had a lower measured concentration than the comparison sample. Whether that demonstrates broader progress depends on sampling location, depth, site coverage and the overall remediation program.

Does one clean follow-up sample prove remediation is complete?

No. One result applies to the submitted sample and location. Site-wide conclusions require an appropriate sampling and decision framework.

Should remediation samples be composited?

It depends on the objective. Composite sampling may provide an average but can also dilute localized contamination, so it should be used carefully.

Can soil microbiology support bioremediation projects?

Potentially. PBR has documented environmental microbiology capabilities for soil matrices, but microbial results should be considered alongside contaminant chemistry and site conditions.

What is the difference between remediation and reclamation?

Remediation generally addresses environmental contamination or impacts. Reclamation more broadly addresses restoration of land conditions. A project may require both types of analytical information.

Should groundwater be tested during soil remediation?

Potentially. If contaminants could migrate to groundwater, environmental water testing may be relevant alongside soil analysis.

What should I do if soil concentrations remain elevated after remediation?

Review the sampling location, depth, treatment coverage, contaminant distribution, related environmental data and project criteria before selecting further sampling or testing.

Does PBR support remediation projects outside Alberta?

Yes. PBR supports projects throughout Alberta, Western Canada and Canada.
