ACS Environmental Testing offer an efficient and reliable WAC testing service. We use various test leaching procedures specified by the Environment Agency (BS EN 12457-2:2002, BS EN 12457-3:2002).

The leachate produced by this procedure is analysed in accordance with strict procedures. The results from some of these tests can then be assessed in accordance with Waste Acceptance Criteria (WAC). This helps to determine the appropriate class of landfill to accept the waste.

The Landfill Directive (2010) requires that before waste can be sent to landfill all of the properties of the waste must be known. The introduction of the Waste Acceptance Criteria (WAC) aims to obtain greater control of the waste disposed of at landfills. The focus is to minimise the impact of this form of disposal.

Landfill is by far the cheapest disposal route for waste. It is therefore cost effective to sample waste in accordance with strict procedures. Waste is also tested to determine whether it meets the WAC criteria. Where waste does not meet the WAC criteria, it is possible that the waste could be processed. This minimises the costs associated with hazardous waste disposal.

ACS Environmental Testing Ltd offer a WAC testing service as well as Full Waste Classification Reporting.

The following parameters are tested from the solid material:

  • Total Organic Carbon
  • Loss on Ignition
  • BTEX (Benzene, Touluene, Ethylbenzene & Xylene)
  • PCB (Polychlorinated Biphenols) (7 x congeners)
  • Mineral Oil (TPH) (Total Petroleum Hydrocarbons)
  • Total PAH (Polyaromatic Hydrocarbons)
  • pH

Eluate Analysis – The following parameters are tested from the laboratory prepared leachate:

  • pH
  • Conductivity
  • Metals
  • Anions
  • Total Dissolved Solids
  • Phenol Index
  • Dissolved Organic Carbon

Deviating Samples

ACS Environmental Testing Ltd strictly comply with the requirements necessary to meet the United Kingdom Accreditation Service (UKAS) Policy on Deviating Samples (TPS 63).

In order to provide a high level of service to our clients, we provide free sample containers. This maintains sample integrity as much as possible after collection. The sample containers are selected specifically to ensure they are the most suitable for all analyses that we currently offer.

Samples are defined as deviating when they do not meet specific criteria. In this instance they may jeopardise the validity of the reported test result.

Examples of deviating samples would include:

  • Incorrect sample container
  • Inappropriate storage temperature
  • Incorrect or lack of preservatives used for time critical parameters
  • No time or date of sampling has been supplied
  • Analysis performed outside of quoted stability holding times
