The nomenclature for Kansas aquifers needs revision. Many of the names currently in use were derived in an ad hoc manner without the benefit of a consistent set of hydrogeologically based guidelines. Because nomenclature forms the basis of scientific discussion of hydrologic issues, names should be clearly defined and consistently applied in order to prevent erroneous or unintended hydrologic i...

Aquifers can be defined as complex ecological systems. Their description is closely influenced by geometrical and geological parameters, which portray the hydrogeological behaviour of underground This paper reports a contribution to assessing groundwater contamination risk in particular Sicily sector, where deterministic approaches have methodically assessed mapped vulnerability quality gr...

A large-scale leaching assessment tool not only illustrates soil (or groundwater) vulnerability in unmonitored areas, but also can identify areas of potential concern for agrochemical contamination. This study describes the methodology of how the statewide leaching tool in Hawaii modified recently for use with pesticides and volatile organic compounds can be extended to the national assessment ...

Groundwater resources from karst aquifers play a major role in the water supply in karst areas in the world, such as in Switzerland. Defining groundwater protection zones in karst environment is frequently not founded on a solid hydrogeological basis. Protection zones are often inadequate and as a result they may be ineffective. In order to improve this situation, the Federal Office for Environ...
