01
Low-flow sampling
Controlled pumping rates, drawdown monitoring and field-parameter stabilisation support representative sampling where low-flow methods are appropriate to the monitoring objective and bore conditions.

Sampling Method & QA/QC
Groundwater sampling.
Representative. Traceable. Defensible.
Detailed sampling methodology supporting Soltera’s integrated Groundwater Monitoring & Sampling service, including low-flow methods, field parameters, QA/QC, preservation and laboratory coordination.
Core field service
Sampling is a data-quality process.
Representative groundwater samples depend on the full field process—not only filling bottles. Soltera plans and executes sampling around the monitoring objectives, bore condition, sampling method, equipment, field parameter behaviour, QA/QC and laboratory requirements.
✓Low-flow and project-specific sampling methods
✓Controlled pumping, drawdown and field-parameter stabilisation
✓Calibrated field instrumentation
✓Field duplicates, blanks and project-specific QA/QC controls
✓Preservation, chain of custody and NATA-accredited laboratory coordination where required
✓Equipment decontamination and cross-contamination controls

Laboratory handoverPreservation, chain of custody and dispatch control
Sampling capability
From bore access to laboratory handover.
A consistent sequence reduces avoidable variability and preserves the traceability of each monitoring event.
02
Purging & field parameters
Field measurements can include pH, electrical conductivity, temperature, dissolved oxygen, oxidation-reduction potential and turbidity, together with pumping rate, drawdown and stabilisation records where required by the sampling method.
03
QA/QC
Field duplicates, blanks and other project-specific controls supported by clear documentation and sample identification.
04
Sample handling
Correct containers, preservation, cooling, holding-time awareness and chain-of-custody control.
05
Laboratory coordination
Coordination with appropriately accredited laboratories to align bottles, analyses, logistics and custody requirements.
06
Field observations
Recording bore condition, access issues, abnormal water levels, visual observations and field conditions that may affect interpretation.
Analytical suite design
Monitor what is relevant to the site.
Where required, Soltera can recommend field and laboratory parameters based on site history, potential contaminant sources, groundwater chemistry, environmental receptors and regulatory requirements—avoiding both important data gaps and unnecessary analysis.
01
Landfills & waste
Site-specific combinations of pH, EC, major ions, nutrients, ammonia, metals, organic indicators, PFAS, hydrocarbons and other leachate-related parameters as relevant.
02
Mining & resources
Parameters may include pH, EC, sulfate, major ions, metals, acidity/alkalinity, salinity and process- or material-specific groundwater indicators.
03
Contaminated & industrial sites
Analytical programs can be tailored to petroleum hydrocarbons, BTEX, chlorinated compounds, PFAS, metals, nutrients, solvents, pesticides and other site-specific contaminants of concern.
Fit-for-purpose means site-specific. Analytical suites are selected after review of the monitoring objective, source-pathway-receptor setting, existing data and relevant regulatory requirements.
Field QA/QC
Every step from bore to laboratory matters.
Soltera’s sampling workflows are designed to make the field record clear, repeatable and reviewable.
Prepare
Review scope, bore list, analytes, containers, access and equipment.
Calibrate
Prepare and check meters against the project procedure.
Sample
Execute the nominated method while recording stabilisation and observations.
Control
Complete QA/QC, preservation, CoC and dispatch within required conditions.

Recurring monitoring
Consistency across every round.
Long-term programs become more valuable when the field method, metadata, sample handling and data structure remain consistent. Soltera can standardise monitoring rounds across sites and reporting periods while documenting deviations when field conditions require them.
