  1.1 The purpose of this annex is to provide background information on:

  • .1 the development and use of methodologies for both indicative and detailed analysis and appropriate sampling; and

  • .2 analysis of the sample at an accredited laboratory.

  1.2 This annex highlights the advantages, disadvantages and limitations of many different measures. Although recommendations are given in this document on what methodologies may be used, there are distinct benefits in using certain technologies at certain times. This should not stop the use of any of the methodologies, as long as the limitations are taken into account.
