Contamination & WAC Testing

As part of our Group of Companies, ACS Environmental Testing offer an efficient and reliable analysis service using 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, and the results from some of these tests can then be assessed in accordance with Waste Acceptance Criteria (WAC) 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 that determine its suitability for landfill must be known. The introduction of the Waste Acceptance Criteria (WAC) aims to obtain greater control of the waste disposed of at landfills to minimise the impact of this form of disposal.

CONTAMINATION & WAC TESTING

Landfill is by far the cheapest disposal route for waste. It is therefore cost effective to sample waste in accordance with strict procedures, and test the waste 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 to minimise the costs associated with hazardous waste disposal.

ACS Environmental Testing Ltd offer WAC testing 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 to maintain sample integrity as much as possible after sampling. The sample containers are selected specifically to ensure they are the most suitable to meet our clients requirements for all analyses that we currently offer.

Samples are defined as deviating when they do not meet specific criteria and 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

For more information regarding our Deviating samples procedure please see our downloads page.
