Abstract
Modern requirements for hydrochemical sampling of observation wells in the performance of hydrogeological research and groundwater monitoring are given. When sampling observation wells is recommended to pump out not less than 40 volumes of water from the borehole with a submersible pump. For determination of inorganic substances it is recommended to use complex mass-spectral and atomic emission analyses with inductively coupled plasma for 72 elements, which will allow to reject the results of analyses for which the conventional methods (with the sensitivity limit, close to the MAC) revealed exceeding the existing standards, for example for Cd, Li, Be.
