Freshwater fishes have important subsistence, cultural, and economic value worldwide (Lynch et al.)1. However, freshwater ecosystems are among the most threatened on the planet with freshwater fishes showing the highest extinction rate among vertebrates in the 20th century (Burkhead 2012)2. The key anthropogenic pressures facing freshwater ecosystems are water extraction, habitat degradation, overexploitation, invasive species, […] More

Rural water service provision typically prioritises quantity over quality, which is often assumed to be adequate where groundwater is used. This practice maintains the separation of water safety from other aspects of rural water service provision, thereby establishing a false dichotomy—one that is reinforced by contradictory assumptions about whether water quality matters to the public.

Tap cleaning To assess tap cleaning agent and method efficacy: (1) a protocol was developed; (2) a system was built to group biofilms in taps and one trial run was completed; (3) four data collection runs, one for each of the four cleaning agents, were completed; and (4) data were analyzed. Through partner discussions, a […] More
