Figure 5

Water total hardness, total dissolved solid, and biological oxygen demand (BOD) of the different river sites at wet and dry seasons of the year. Study sites: GS = Gacheb site, TS = Tsit site, KS: Kosokol site, RS1 = Reservoir site 1, and RS2 = Reservoir site 2. Number of replicates (n = 3). Mean values of the different sites water total hardness, total dissolved solid, and BOD with similar letter within the same season (wet or dry season) are not significantly different to each other at . The red dotted line is the WHO limits for drinking water quality.
