Metal content analysis for landfill acceptance

Recently at Envirochem we have noticed that more and more landfills are requesting additional testing along with the normal Landfill Waste Acceptance Criteria test (WAC test or Leachate test). Typically these include: metal content of air dried sample, speciated TPHs (total petroleum hydrocarbons, either as banded or aliphatic/aromatic split) and speciated PAHs (polyaromatic hydrocarbons).

Envirochem laboratories offer these services to their clients; therefore, we would advise contacting the landfill site or waste receiver to check if the additional analysis is required to save you time. We will always retain samples for a period of time and can carry out additional testing at short notice.

Landfill Waste Acceptance Criteria (WAC).

Written by

At Envirochem, we have been experiencing an increase in requests for soil and waste samples to be analysed to ascertain whether they can be disposed of at landfill, which requires adherence to certain Landfill Waste Acceptance Criteria (WAC).

The Landfill Directive is an EU directive which is designed to regulate the use of landfill sites and, most importantly, what is dumped at each site. The Landfill Directive’s overall aim is “to prevent or reduce as far as possible negative effects on the environment, in particular the pollution of surface water, groundwater, soil and air, and on the global environment, including the greenhouse effect, as well as any resulting risk to human health, from the land filling of waste, during the whole life-cycle of the landfill”. For a landfill site to adhere to this directive, waste to be dumped at the site must have a certificate showing that it is not too contaminated. An example of a certificate would be a WAC certificate. Please note that some landfill sites require additional testing to a standard WAC suite, such as a digest for metals.

In addition to the Landfill Waste Acceptance Criteria test (WAC test or Leachate test), there are guidances, such as the WM3 guidance, to help in the classification process of hazardous waste and to inform individuals what analysis they will require.

The requirement for WAC testing can depend on a number of different factors such as sample type, location and history of the site; therefore it is common for different samples to have a slightly different scheme of analysis. Because of this, Envirochem offers a wide range of soil and waste tests which include, but are not limited to, metals content; anions; speciated TPH and PAH; BTEX; PCBs; and volatile organic compounds (VOCs) which allows us to provide a bespoke scheme of analysis to meet the needs of clients from a vast range of industries.

 

We can do WAC testing on a turnaround of 7 days, 5 days or 3 days depending on your needs. (Cost apply faster turnarounds).

WAC TESTING

Written by

WAC TESTING

Envirochem undertakes Landfill Waste Acceptance Criteria (WAC) testing:

WAC testing is used to determine how a waste will behave once buried in a landfill. This is carried out through analysis of leachate derived from the waste during laboratory analysis. Following testing, a certificate of analysis will be issued.

WAC testing can be carried out on:

– Contaminated soil

– Spent grit

– Industrial waste and other waste streams

 We also offer:

– Total metals by acid digest analysis

– Sample tubs free of charge

– Pick up service and site sampling available

Identification of unlabelled substances to determine what they contain

Written by

At Envirochem, we often receive unusual samples for analysis. One recent example of this was a set of around 60 bottles collected by us from a residential property. The bottles had been found during a house clearance as the previous owner had owned his own printing company. We created an inventory of the compounds in order to request a quote from a disposal company that we work with. We plan to analyse any unlabelled substances to determine what they are.

During the inventory, we found two bottles containing mercury. Mercury is a very interesting element. It is the only metal to be liquid at room temperature and has a very high surface tension, so forms rounded beads of liquid.

We test many different types of samples for mercury including soil, water, leachates (as part of the WAC testing suite of analysis) and air (mercury fumes or dust).

Asbestos in soil analysis

Written by

Envirochem offer a wide range of accredited asbestos services, including Asbestos in Soil. The analysis of soil samples, depending on your needs can report;

  • The presence of asbestos
  • The asbestos product type
  • The percentage of asbestos
    present within the sample

Analysis will enable the end user to:

  • Assist with the determination
    of the Waste Acceptance
    Criteria
  • Identify potential for asbestos
    exposure adjacent
    to contaminated land
  •  Identify the total percentage
    of asbestos present in
    the sample.

New Ion Chromatograph

Written by

Envirochem has completed the installation of our new Ion Chromatograph. This is part of our rolling scheme of improvement of analytical equipment. This allows us to maintain our high standards and quality of analysis.

The new Metrohm IC883 has already been subjected to and passed a mini validation and so can be used for UKAS testing of water samples for fluoride, chloride, bromide, nitrate and sulphate. It can also test for nitrite and phosphate. The ion chromatograph is also for Mcerts accredited work for chloride and sulphate in soils.

The ion chromatograph can be used in swab analyses to test surface contamination before and after cleaning works, as well as analysis of samples from occupational hygiene work for acid fumes such a s nitric acid, sulphuric acid and hydrochloric acid in the workplace.

Leachate samples from Landfill Waste Acceptance Criteria (WAC) samples, will also run through this instrument.

The old ion chromatograph (on the left in the photo) will be utilised to run speciated phenols in waters and soil extracts. The two instruments are linked so that the same sample can be analysed for anions and phenols. We will be able to speciate and quantify common environmental phenol compounds such a creosols and chlorinated phenols.

The new software also allows the direct transfer of analysis data into our Laboratory Information Management system reducing the time taken and the chance of transcription errors.
