Fresh groundwater, as an essential component of global water resources and a special type mineral wealth, has whole set features that affect social infrastructure, the economy environmental well-being population. At same time, groundwater is vulnerable limited despite its replenishable nature vast reserves. Recently, in some countries, practice extracting by private individuals on their territory been actively spreading, but not all states. This considered acceptable enshrined national regulations. Uncontrolled exploitation aquifers small users can safety ecosystems depletion drinking In this regard, state policy system for regulating access to subsoil should be based well-thought-out concept. article devoted organizational, economic, regulatory issues extraction own needs Russian Federation. A comparative analysis approach other states (mainly example Germany China) made. The latest trends legislation area are analyzed, shortcomings regulation use identified, mechanisms legalizing activities individual proposed.
