Characteristics of Test Areas

Test areas have been selected on the basis of  

Although there are numerous different water types to be considered, for the purpose of validation of the protocol the actual lead concentration found in a test area is the most important factor. Three types of area can be distinguished, namely areas with low, medium and high plumbosolvency. A number of properties with comparable water quality (not necessarily the same supply area) is considered as one area. Per area about 30 properties were selected. 

The field tests were performed in eleven areas. The samples from each area were analysed by national laboratories that had proved capable of meeting the demands on analytical capabilities (Section 3.2.4).
