Contaminated Land (CONTEST)

daps UKAS Logo
  • UKAS accredited proficiency testing scheme
  • The LGC CONTEST scheme offers a comprehensive range of analytes in soils, soil extracts and standards solutions for the analysis of metals, inorganic contaminants, organics, soil leachates and solid waste.
  • Land contamination can pose both environmental and human health risks. The main causes of contamination are the direct discharge of industrial wastes, domestic pollution, over-usage of pesticides, oil and fuel dumping, leaching of wastes from landfills and leaking underground storage tanks which corrode over time releasing toxic substances into previously clean soils.
  • Participation in a proficiency testing scheme for soil, such as CONTEST, is a requirement of the UK Environment Agency’s Monitoring Certification Scheme (MCERTS) ‘Performance Standard for Laboratories Undertaking Chemical Testing of Soil’.
  • Scheme operates from April to March
