Preparing a WAC Testing Pack: A Practical Checklist for UK Projects

Landfills and regulators are placing increasing emphasis on the quality of documentation that accompanies each waste load. A well‑structured WAC Testing pack not only speeds up acceptance at the gate but also reduces the risk of disputes months or years down the line.

At a minimum, a robust pack should include a clear description of the source area and excavation activity; drawings or sketches showing sampling locations; chain‑of‑custody records for each sample; laboratory certificates; waste classification calculations; and an interpretive summary explaining how the results support the chosen disposal route.

EnviroSolution’s WAC Testing service is built around producing exactly that kind of package. We start by agreeing the sampling scope and documenting it in a short plan that can be shared with clients, regulators or landfill operators if needed. During sampling, we record conditions, depths and material types so that each sample can be tied back to a specific part of the works.

Laboratory results are then collated into an easy‑to‑follow report that maps each stockpile or load to its relevant WAC results and landfill acceptance status. Where appropriate, we include template wording for waste transfer notes or consignment documentation so that there is a consistent message from site to gate.

For project managers and commercial teams, having this level of structure turns WAC from an opaque technical topic into a straightforward checklist item and demonstrates to regulators and clients that Duty of Care responsibilities are taken seriously.
