Interesting/troubling study on effects of coffee processing on Jimma R. in Ethiopia Are naturals part of the solution?

In this study, the authors found significant reductions in water quality downstream from coffee processing plants during the wet season. During the wet season, they saw a large increase in organic loads, nutrients, and solids, which resulted in dissolved oxygen levels to as little as 0.1 mg/L water. They also found that during the processing peak that the average pH of river waters was lowered from 7 to 6.2. This combination of changes led to a decrease in diversity of macroinvertebrates. During the dry season, the scientists found that the organic load, dissolved oxygen, solids, and pH had recovered to mostly normal levels. They found that the overall macroinvertebrate diversity was restored during this time period, but that the most sensitive taxa remained at low percentages, indicating a longer-term impact on the ecosystem. Interestingly, since the dissolved oxygen was ...
