[en] Adressed is the problem of monitoring contaminated land for the presence of hazardous and/or toxic materials. This chapter is primarily concerned with methods of chemical analysis that can be readily applied in the field, can provide real time data and be cost effective. The study has been restricted to a user survey rather than an extensive literature search. The survey supplies information on available techniques and provides recommendations regarding their proper application. Topics discussed include sampling, sampling design, sample matrices, compatibility testing, air monitoring equipment, soil monitoring techniques, specialized screening techniques and mobile analytical laboratories
