Hydrogeological and geophysical investigations for groundwater in the Arumeru District (Northern Tanzania)

Due to water shortage, in the wards of Ngarenanyuki and
Oldonyosambu (Arumeru District, Northern Tanzania), the per
capita daily water consumption is 8 liters as.average, The
avaleability goes down to 3-4 liters in the dry seasons when
most of the population cannot resort to seasonal ponds or
streams and so it is compelled to concentrate around the few
perennial water points. This datum is quite far from the
Millennium Goal objectives that foresee a quantity of at least
20 l/d/p (litres per day per person) for the Development
Countries population, within 2015. Problems are also related to
water quality, in particular, the high concentration of fluoride
that characterises the waters in East Africa Rift System.
