Sample assessment

See what you receive

What a GDM assessment contains, and how every statement in it traces back to a laboratory result or a cited standard.

The published synthetic sample is in preparation. Request a copy below and we will send it as soon as it is released.

How an assessment is structured

The same structure, whether soil, groundwater or integrated

Section 1

Scope and inputs

The site, the applicable schedule, and every input the assessment is built from, the laboratory certificates, borehole logs and reports you provided, listed so the result is reproducible from them.

Section 2

Data quality assurance

The checks run before any interpretation: unit conformance against the schedule, charge balance where it applies, and laboratory qualifiers such as < and > preserved rather than discarded.

Section 3

Parameter coverage

Every parameter the schedule names, checked for presence and for unit. What is present, what is missing, and what was reported in a unit other than the one prescribed, stated, never quietly dropped.

Section 4

Threshold comparison

Each result compared against its registered screening value by a deterministic, versioned rule. Where no threshold is registered, that is reported explicitly and never filled with an assumed value.

Section 5

Interpretation

What the data indicates, recharge source, salinity origin, contaminant signature, or the pathway from surface soils to groundwater, with the disclosure class of every statement stated: measured, inferred, interpreted or recommended.

Section 6

Findings, limitations and recommendations

The conclusions, the uncertainties and data gaps stated plainly rather than in a footnote, and the recommended next steps. In a certified assessment, a signed cover names the responsible specialist.

Traceability

Every finding traces to a lab result or a cited standard

No number, threshold or benchmark appears without a traceable source. Each result is carried with the value it was compared against, the source of that value, and the laboratory qualifiers as reported. Where a required parameter is absent, it is reported as absent. Where no screening value exists, the parameter is reported as unscreened, never silently filled from an unrelated standard. The whole assessment is reproducible from the archived inputs.

Draft and certified

The difference a signature makes

Draft assessment

Every statement traces to a lab result or a cited standard. No specialist has certified it yet.

Certified assessment

Reviewed claim by claim and signed by the named specialist responsible.

Ask for the sample assessment

The published sample is a synthetic assessment generated on a fictional site and reviewed by our specialist before release. Leave your details and we will send it as soon as it is available, along with a note on how it maps to your own site.

We never use submitted data beyond responding to your enquiry.
