These include:  basic geological, hydrogeological, geophysical and  water quality analysis.  The area is underlain by  Precambrian migmatite gneiss, granite, shists and  newer basalts. The results of geophysical survey  using the electromagnetic (EM) and resistivity  methods proved to be effective in locating and  assessing regolith aquifers. Interpretation of the  sounding curves obtained in the study area,  suggests that the subsurface layering ranges from 3- 5 layers.The evaluation of hydrogeological borehole  parameters gave borehole yield range of 25.9 -  1089m3\/day with a mean value of 275m3\/day.   The specific capacity values ranged from 0.528 -  132.48m3\/day\/m. The value of  transmissivity of the boreholes ranged from 0.359  to 101m2\/day. The quality of water exhibits low  total mineralization. The groundwater can be  classified as Ca-Na-HCO3 fresh water. A survey of  52 existing boreholes showed that more than 60%  were not functioning due lack of geophysical  surveys, proper borehole design and maintenance.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843391726\"\u003e\u003ch3\u003eExamples from Southern Part of Kaduna State, Nigeria\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843391726","offer_id":39469957906525,"sku":"9783843391726","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/52ac2f9c-e176-4343-8306-b492684eda2f.jpg?v=1772866301","url":"https:\/\/shop.autorenwelt.de\/en\/products\/groundwater-exploration-and-development-in-basement-complex-area-von-martin-eduvie","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
