If precise knowledge about water resources is available for new project planning, negative consequences for the environment can be avoided. Examples for negative consequences are decreasing of the ground water levels, dying of vegetation and the extension of deserts. Moreover, it is possible to make over salted infertile soil fertile again through leaching with water, if evaporation is known. For new technologies such as Alpha-Spring that are based on sorption, favourable locations for water extraction in dry areas can be found by using the collected data.
