Abstract This chapter presents a general overview of procedures and methods for sampling and analysis of contaminants in water and soil in the road environment. The chapter concerns the water and seepage in road structures under the influence of traffic loading, and in the adjacent ground extending to the water table where contaminant seepage is of concern. The text gives an introduction to this subject and guides the reader to relevant literature with detailed information about practices of sampling and analysis. The chapter in divided into five main sections: principles of data collection and storage, sampling design, water and soil sampling procedures, and in-situ and laboratory measurements and analyses.

7.1 Introduction

The purpose of contaminant sampling and analysis is mainly to characterize a specific road in terms of its runoff characteristics and the water percolating vertically through the road structure, as well as the existing state of quality of the adjacent water and soil. Sampling and analysis can also be performed to identify a specific pollution episode. The environmental compartments, usually considered as being potentially affected, comprise surface waters, groundwater, soil and soil water. To­gether they can give a global picture of contaminant dispersion and pathways after entering the soil (see Chapter 6). [16] [17]
