Contaminated Land (CONTEST)

The CONTEST scheme we offer covers 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-use of pesticides, oil and fuel dumping, leaching of wastes from landfills and leaking underground storage tanks that 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’.
