PENENTUAN TIPOLOGI AKIFER BERDASARKAN METODA GEOLISTRIK DAN HIDROKIMIA, KOTA TANGERANG
Abstrak
Electrical sounding expectation is used to estimate the early model from a groundwater system in the
field, which can be used as a comparison of field results. The comparison enhances to entrust the process
of field activities and provide the opportunity to modify the programs in the field and to ensure that we have
enough information received efficiently - in a point of view of geological framework. A Usefulness of a
mapping hydrogeology is to show the under surface geometry (structure) and the hydraulic property from
earth materials which is used to investigate the hydrodynamic property appeared from the underground
water on natural shares ( Basin) or a part of its filler.
The exploration using the method of the electrical sounding is conducted on land surface by injecting a
directional current (DC) with a low frequency into a deeper ground passing through two current electrodes.
A different potential capacity is measured on the surface by two potential electrodes. The result of the
measurement capacity which is injected and the potential difference occurred in every different electrode
distance will give a value variation of a typical resistance. The value variation shows the existence of an
underground rock coat variation, while the method of hydrochemistry explains the genesis of the
groundwater based on a physical characteristic and chemistry substances on the field.
Both methods are expected to reconstruct the aquifer condition and its system through surface and
underground surveys. The combination results of both surveys must be depicted in a form of a
hydrogeology map (and its differential map), a block diagram depicting the aquifer, and aquifer system in
a form of two dimensions. The other surface hydrogeology surveys use geological method. In contrast, the
underground hydrogeology survey use the electrical sounding method.
