Phase 2 contamination sampling app for soil investigations
A Phase 2 investigation turns the areas of concern from a Phase 1 into numbers: test pits or boreholes logged by depth, soil samples screened with a PID and sent to a NATA-accredited laboratory, and results compared with investigation levels for the proposed land use. The report has to say, for every exceedance, where it was, how deep, and what it means. That depends on borehole logs and sample IDs staying consistent from field sheet to results table.
Built for consultants running teams of roughly 3–50 inspectors.

| Depth (m) | Description / PID | Sampled |
|---|---|---|
| 0.0–0.4 | FILL: silty sand, brown, with glass fragments; PID 0.8 ppm | Sampled: BH03_0.2 |
| 0.4–1.1 | FILL: clayey gravel, dark grey, hydrocarbon odour; PID 46 ppm | Sampled: BH03_0.8 |
| 1.1–2.0 | CLAY: natural, orange-brown, stiff; PID 2.1 ppm | Sampled: BH03_1.5 |
| 2.0 | Refusal on weathered rock | Sampled: Refusal |
Fields captured on site
Your firm builds the form in-app, so these are a starting point rather than a fixed schema. Every field is captured on the device, with or without signal, and lands in the sampling analysis report where your template puts it.
Per borehole or test pit
- Location ID and map point
- Drilling method and refusal depth
- Groundwater encountered
Per soil interval (nested)
- Depth from / to
- Soil description and fill indicators
- PID reading
- Odour and staining
- Sample ID and container
QA
- Duplicate and split samples
- Decontamination between locations
- Chain-of-custody number
Standards the report works to
- NEPM 1999 (amended 2013)National Environment Protection (Assessment of Site Contamination) Measure
- Health and ecological investigation levels the results tables are screened against.
- AS 4482.1-2005Guide to the investigation and sampling of sites with potentially contaminated soil — Non-volatile and semi-volatile compounds
- Sampling density and design for the non-volatile analytes.
- AS 4482.2-1999Guide to the sampling and investigation of potentially contaminated soil — Volatile substances
- Sample handling for TRH and BTEX, where loss of volatiles skews results.
Load the standards you hold into your reference library and the drafted prose is written against them rather than against a general model.
How the sampling analysis report gets built
Capture it once, offline
Your firm builds the phase 2 contamination sampling form in-app — 25 field types, nesting repeatable groups, compound AND/OR visibility rules, reusable modules and calculated fields. Field capture works with no signal: jobs, forms, photos, notes and audio all queue in an idempotent outbox that only clears once the server confirms receipt.
Link it to your sample locations
Enter sample locations once, as a register. Every one of your samples, bores and monitoring rounds then points at a stored row rather than a name somebody typed — and the links survive a disconnected device.
Render your own template
The sampling analysis report renders into the Word template you already use — your letterhead, your section order, your clause library — with conditionals, loops over repeats, composable sub-templates and photo grids.
Reviewed before it leaves
You write the review framework: a checklist of what a sampling analysis report must contain, plus the prose standards you would mark a junior against. Link it to a report template and it runs every time that template renders. Each finding comes back graded info, minor or major, quoting the sentence at fault, and a person accepts or dismisses every one.
Because the structured submission behind the report is held too, the review is a comparison rather than a proofread: The report says every bore was sampled to three metres; the form has BH07 refused at 1.2 m.
Checks a environmental framework usually carries
- Every exceedance in the results tables is discussed in the assessment text
- The guideline values cited match the land use actually being assessed
- No sample or bore ID appears in the prose that is absent from the data
- Data gaps, refusals and deviations from the sampling plan are stated as limitations
Questions
- Can a borehole have multiple sampled intervals?
- Yes. Intervals are a repeat nested inside each borehole, so the log and the sample register are built from the same rows.
- Will the report catch a sample ID that does not match the log?
- The report review compares the finished document with the captured data, so an ID mentioned in the text but absent from the logs is raised as a finding.
- Can we record a refusal rather than leaving a gap?
- Refusal depth is its own field, and the review framework can require every refusal to be stated as a limitation.
- Does it calculate exceedances from laboratory results?
- No. Laboratory data management stays in your existing tools; SurveyThanks holds the field record and produces the report.
What this is not
Worth knowing before you book a demo, so neither of us wastes the half hour.
- Not field-service dispatch. No timesheets, no parts, no inventory. Scheduling exists to get an inspector to a site.
- No signature capture. If your deliverable has to carry a signed sign-off on the artefact itself, this is not the tool yet.
- Field capture is what works offline — jobs, forms, photos, notes and audio. Reports, chat, scheduling and the inbox need a connection.
- No client portal. Reports go out as a file or a password-protected link.
