Contaminated Land

DETS offer a fully comprehensive service covering all commonly requested soil contaminants.  We were one of the first laboratories to receive MCERTS accreditation, which provides a level of validation across three soil matrices – sand, clay and loamy soil – and this certification sits over and above ISO 17025, providing greater levels of data confidence.

Associated testing includes leaching tests and landfill gas.

Common parameters include:

  • Toxic metals including CLEA metals (contaminated land exposure assessment)–Cd, Cu, Cr, Hg, Ni, Pb, Zn, Fe, Al, Be, As, B, etc.
  • Major cations– Na, K, Ca, Mg
  • Inorganics/physical – pH, EC, calorific value
  • Anions (water soluble) – Cl, NO3, NO2, SO4, PO4
  • Cyanides – Total, Free (easily liberatable), Thiocyanate
  • Phenols
  • Sulphur compounds – total sulphur, sulphide, sulphate
  • Asbestos – screening, identification, quantification and water absorption
  • TOC – total organic carbon, loss on ignition
  • VOCs – volatile organic compounds
  • SVOCs – semivolatile organic compounds
  • TPH – GRO, EPH, speciated TPH, BTEX
  • PAHs – polyaromatic hydrocarbons
  • PCBs – polychlorinated biphenyls
  • Pesticides & herbicides – chlorinated, phosphorylated, triazines
  • Dioxins and furans
  • Waste characterisation – see Waste Management

DETS provide suitable sample containers for clients to take their own samples. Courier service is also available.

Samples are given a brief description to comply with MCERTsS, mixed, then subsampled.  Most analyses are performed on the wet, as received soil, but where possible, samples are dried at less than 30°C, then crushed.   Analyses performed on the wet soils are corrected and reported on a dry weight basis, again to comply with MCERTSs.

Larger bulk samples, such as railway ballast or gravel, can also be analysed upon request.
