CONTEST - Contaminated land schemeTest materialAnalytesWater andenvironmentPT schemesLand contamination can pose both environmentaland human health risks. The main causes ofcontamination are direct discharge of industrialwastes, domestic pollution, over-usage ofpesticides, oil and fuel dumping, leaching ofwastes from landfills and leaking undergroundstorage tanks which corrode over time releasingtoxic substances into previously clean soils.The CONTEST scheme has been exclusivelydeveloped for contaminated soils and the primaryaim is to enable laboratories performing theanalysis of soils to monitor their performance andcompare it with that of their peers. CONTESTwill also enable participants to demonstrate tocustomers, regulators and accreditation bodiesthe validity of their analytical measurements.Participation in a proficiency <strong>testing</strong> schemefor soil, such as CONTEST, is a requirementof the UK Environment Agency’s MonitoringCertification Scheme (MCERTS) “PerformanceStandard for Laboratories Undertaking ChemicalTesting of Soil”.The CONTEST scheme includes acomprehensive range of analytes of relevanceto the <strong>testing</strong> of soils. The test materials areavailable as standard solutions, soil extractsand soil materials for the analysis of metals,inorganic contaminants (chlorides, cyanides,fluorides, sulphites), organics (BTEX, chlorinatedhydrocarbons, PAH’s, PCB’s, phenols, TPH) andsoil leachates.The full range and availability of test materialsin CONTEST is determined on an annual basisand further details can be found in the CONTESTapplication form and scheme description.Polyaromatic Hydrocarbons(PAHs):Soil and Standard SolutionAcenaphthene, Acenaphthylene,Anthracene, Benz(a)anthracene,Benz(a)pyrene,Benzo(b)fluoranthene,Benzo(ghi)perylene,Benzo(k)fluoranthene, Chrysene,Dibenz(ah)anthracene,Fluoranthene, Fluorene,Indeno(123-cd)pyrene,Naphthalene, Phenanthrene,Pyrene, Total PAH.Polychlorobiphenyls (PCBs): PCB (28), PCB (52), PCB (101),Soil and Standard Solution PCB (118), PCB (138), PCB (153),PCB (180).Total Petroleum Hydrocarbons(TPH):Soil and Standard SolutionTotal TPH (C 10 -C 40 inclusive),TPH Aliphatic C 10 -C 12 (inclusive),TPH Aliphatic C 13 -C 16 (inclusive),TPH Aliphatic C 17 -C 21 (inclusive),TPH Aliphatic C 23 -C 35 (inclusive),TPH Aliphatic C 36 -C 40 (inclusive),TPH Aromatic EC 10 -EC 12 (inclusive),TPH Aromatic EC 13 -EC 16 (inclusive),TPH Aromatic EC 17 -EC 21 (inclusive),TPH Aromatic EC 22 -EC 35 (inclusive),TPH Aromatic EC 36 -EC 40 (inclusive).Total Petroleum Hydrocarbons TPH Aliphatic ≤C 6 ,(TPH): Volatile range:TPH Aliphatic C 7 -C 8 (inclusive),Standard SolutionTPH Aliphatic C 9 -C 10 (inclusive),TPH Aromatic C 6 (inclusive),TPH Aromatic C 7 -C 8 (inclusive),TPH Aromatic C 9 -C 10 (inclusive).Chlorinated Hydrocarbons:Standard SolutionBTEX:Standard SolutionPhenols:Soil and Standard SolutionsSemi-Volatile OrganicCompounds: (SVOC)Standard SolutionMiscellaneous:SoilChlorobenzenes, Dichloromethane,Hexachloro-1,3-butadiene,Tetrachloromethane,Trichloroethene, Trichloromethane,Vinyl Chloride,1,1,1,2-Tetrachloroethane,1,1,1-Trichloroethane,1,2-Dichloroethane,1,2-Dichloroethene,2-Chlorotoluene.Benzene, Ethylbenzene,m- + p-Xylenes, o-Xylene, Toluene.Cresols, Phenol, XylenolsTotal Phenols (sum of phenol,cresols and xylenols, individuallyquantified).Distillable Phenolic Substances,Total Monohydric Phenols.SVOCs (Qualitative identification).Elemental Sulfur.Total Organic Carbon.26 Tel: +44 (0)161 762 2500 Fax: +44 (0)161 762 2501
