Hydrogeology and Chemistry Synthesis of the Deep Boring Of the Township Of Abomey-Calavi.

Abstract

In the setting of the backing of the food in drinking water of the population of the cities of Abomey-Calavi, Sèmè and Cotonou biggest city of Benin, the General Direction of water (DG-Water) and the Society Nationnale of the Waters of Benin (SONEB) achieved many boring in the township of Abomey-Calavi. It is the biggest field of intensive catchment of Benin; but whose hydrogeology and chemistry is known little.  During the year 2013, we sampled these boring and studied the hydrogeology of the township of Abomey-Calavi. These deep boring of about hundred meter on average, permit to appropriate water in the aquifer of the continental terminal. It is an aquifer of the sands (end to coarse) of wills and gravels with of the argil – sandy levels (red lateritic, gaudy, black or colorful). We mobilized water from 77 boring. The averages of the results of analyses by precinct permitted to make a synthesis of hydrogeology and hydrochemistry of the township of Abomey-Calavi. The water of boring of the township of Abomey-Calavi are possesses one feature chlorinated sodic potassic or bicarbonated sodic potassic.
