A Biological Assessment Of Water Quality In El Placer, Ecuador: The Effect Of Agriculture On Stream Health And The Quality Of Historical Versus Current Drinking Water Sources, Danielle Kleinberg
A Biological Assessment Of Water Quality In El Placer, Ecuador: The Effect Of Agriculture On Stream Health And The Quality Of Historical Versus Current Drinking Water Sources, Danielle Kleinberg
Independent Study Project (ISP) Collection
Although fresh water is one of Ecuador’s most abundant resources, high quality drinking water for its inhabitants is scarce (Wingfield et al., 2021). The most prevalent sources of water pollution in Ecuador are domestic waste, silver and gold mining, oil production, and agricultural chemicals (Buckalew et al., 1997). El Placer, a village located in Tungurahua, Ecuador, is highly dependent on agriculture as a source of income. The first objective of this study was to determine the effect of agriculture on the El Placer’s Tía Anita Stream through comparing the water quality at three sites with varying agricultural influence. The second …
The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison
The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison
Independent Study Project (ISP) Collection
The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …
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 …
