known how far these extend (Howard et al., 2003). Previous studies have shown that the top
of the regolith is composed of fine material, with increasingly coarser (sandy clay) material
found at depth with productive aquifers commonly associated with these layers (Howard et
al., 2003; Kulabako et al., 2007). Recharge tends to occur during two distinct wet seasons,
although Kampala experiences rainfall throughout the year due to its proximity to Lake
Victoria (Howard et al., 2003, Nyenje et al., 2010)

7.2.2 Sample collection and analyses
To assess the state of pollution of the springs in the Kampala area, a total of 77 springs were
sampled. The locations of the springs are indicated on Fig. 7.1 .
