5                   Analytical methods
The following Sections describe the methods recommended to analyse soil from a contaminated site.

It sets out methods for:

physicochemical analyses:
soil moisture
pH
electrical conductivity
cation exchange capacity
water soluble chloride
organic carbon

inorganic contaminants:
metals – including separate methods for mercury, chromium VI
halides – bromides, fluoride
non-metals – cyanide, sulfur compounds

organic contaminants:
volatile organics  including MAHs, VHCs, and vTRHs
semi-volatile organics  including PAHs, PCBs, pesticides (OPPs, OCPs, chlorinated herbicides), phenols, phthalate esters, dioxins and furans, TRH and TRH – silica.

5.1              Method selection
For some analyte groups, two or more alternative procedures are suggested, which differ in extraction method, clean-up (or lack of), the final determinative step, or a combination of these. The preferred technique will incorporate mass-selective detection and will have more favourable detector selectivity or clean-up steps employed. These methods are less likely to be subject to errors due to interference from co-extracted, non-target compounds. The alternative techniques are known to be useful but would normally require additional independent verification of analyte identity and concentration.

The preferred method is denoted by 'P'.
