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 …
River Health In Puyo, Ecuador The Use Of Macroinvertebrates As Bioindicators Of Water Quality And Alternatives To Chlorine For Whitening Clothes In The Puyo River Watershed, Allison Rowe
Independent Study Project (ISP) Collection
Fresh water is an important resource in Puyo, Ecuador, a city named after the Kichwa word for ‘cloudy’ in reference to its overcast weather. However, the Puyo River watershed is the most contaminated in all of Pastaza Province. The objective of this investigation was first to evaluate the health of the Puyo River using macroinvertebrate analyses and measurements of chlorine concentrations, temperature, pH, turbidity, velocity, and flow rate. The second objective was to learn about practices used to whiten clothes in Puyo and perceptions of water quality in order to understand the magnitude of bleach pollution and the population’s awareness …
