Water Quality In The Río Pastaza Watershed A Comparative Study Of Ríos Topo, Zuñag, And Pastaza And The Impact Of The Topo Hydroelectric Project Using Macroinvertebrates As Bioindicators, Jesse Vega-Perkins
Independent Study Project (ISP) Collection
Ríos Zuñag, Pastaza, and Topo flow through one of the rainiest and water-rich places in Ecuador. Río Zuñag is a relatively small, pristine montane river and Río Pastaza is a relatively large, contaminated river that receives the untreated wastewater of many communities. Río Topo’s unique watershed and gradient allow it to be home to many plants that have adapted to its unique environment, including the hyperendemic liverwort Myriocolea irrorata. However, in recent years, all of the water of Río Topo has been sold by the state of Ecuador to be developed for hydroelectric projects (HEP). The first of these …
Human Impacts On Water Systems: Biological Assessment Of Water Quality In The Bosque Protector Río Guajalito (Bprg) Using Aquatic Macroinvertebrates, Harrison Smith
Independent Study Project (ISP) Collection
Benthic macroinvertebrates have been extensively used as bioindicators for water quality due to their varying sensitivity to a diverse range of impacts on hydrographic sources. In this study a sampling of macroinvertebrates was carried out in the Guajalito and Brincador rivers and a small creek that runs through the private reserve Bosque Protector Rio Guajalito in order to analyze if the health of the rivers has changed in relation to previous studies. The sampling stations were located upstream and downstream of potential sources of disturbance in each of the three streams sampled in order to determine what level of impact …
