2.3 Sampling and Analysis Plan Rationale
The assessment of sediment contamination for land-based re-use will be undertaken in accordance
with relevant requirements set out in the NEPM. NEPM investigation levels are based on the Health-
based Investigation Levels (HILs) for public open space (HIL – C).

As some material will also be placed below HAT, samples will be compared against screening levels
set out in the NAGD (2009). Furthermore, as NAGD (2009) represent good practice for sampling and
assessment of marine sediments, these guidelines informed the study design (i.e. site selection,
sampling effort, derivation of contaminant list) and sampling and analysis methodology.

Other guidelines set out by the Queensland government’s Model Operating Conditions, ERA 16 –
Extractive and Screening Activities (DEHP 2017) are referred to, including the Queensland Acid Sulfate
Soil Technical Manual (QASSTM, Dear et al., 2014).
