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 …
Beach Or Bush? A Study On Sanitation And Clean Water In Ushongo Village, Charlotte Vetter
Beach Or Bush? A Study On Sanitation And Clean Water In Ushongo Village, Charlotte Vetter
Independent Study Project (ISP) Collection
The purpose of this study was to examine the issues with sanitation and clean water in Ushongo Mtoni Village and then use these findings to determine weather Ushongo Mtoni meets the 2014 World Health Organizations target goals for sanitation and clean water: eliminate open defecation; achieve universal access to basic drinking water, sanitation and hygiene for households. This study was conducted in Ushongo Mtoni, Tanzania, between the dates of November 10th to 24th 2014. Interviews were conducted using non-random sampling through formal and non-formal interviews with participants chosen by my translator, Shaban. Sample frame was the villagers of …
For Want Of Water, A Will: Community Participation In The Development Of A Potable Water Project In Melio, Cameroon, Morgan Yucel
For Want Of Water, A Will: Community Participation In The Development Of A Potable Water Project In Melio, Cameroon, Morgan Yucel
Independent Study Project (ISP) Collection
By taking the water system in Melio-Baleveng, Cameroon as a case study for investigation, this paper explores the successes and challenges of community participation in water project development. Essential for life, and critical for the productivity of populations, potable water remains a scarce resource in developing countries. Facing a failure of government action and a dire need for potable water, the community of Melio partnered with the non-profit Breaking Ground in 2013 to realize a water project. A year after the project’s completion, water still flows from the fountains, but the project’s future remains uncertain as the impoverished community struggles …
Pollution In Stone Town’S Coastal Waters: An Assessment Of Environmental Influences On Fecal Contamination, Socorro Lopez
Pollution In Stone Town’S Coastal Waters: An Assessment Of Environmental Influences On Fecal Contamination, Socorro Lopez
Independent Study Project (ISP) Collection
Urbanized areas in Tanzania, including Zanzibar Town on Unguja, are struggling to deal with the large amount of waste generated by growing populations and increasing tourist industries. In 2010, the waters surrounding Stone Town, a subsection of Zanzibar Town, were found to be highly polluted by fecal waste. This study attempted to determine whether pollution has lessened or worsened in the past four years. Furthermore, environmental components of the coastal area, particularly tides, were tested in order to determine whether they had an impact on pollution in the waters. Using the membrane filtration method, mean enterococci were quantified in two …
Bioremediation Of Polluted Zanzibar Seawater: The Nutrient And Bacterial Bioextraction Potential Of Native Seaweeds And Bivalves, Katie Bergman
Bioremediation Of Polluted Zanzibar Seawater: The Nutrient And Bacterial Bioextraction Potential Of Native Seaweeds And Bivalves, Katie Bergman
Independent Study Project (ISP) Collection
In Stone Town, Zanzibar, increasing populations and insufficient sewage treatment has greatly increased harmful levels of nutrients and anthropogenic-sourced contaminants along the city’s coastal waters. In this study, the nutrient and bacterial bioextractive abilities of local species of bivalves (A. antiquata, P. margaritifera) and seaweeds (E. denticulatum, U. reticulata) were examined in order to determine the potential for these species to remedy the local polluted waters. It was hypothesized that due to bivalves’ suspension-feeding activity, both species of bivalves would be able to decrease turbidity and fecal indicator bacteria (Enterococci) levels in sample polluted …
From Holy To Holistic: Working Towards Integrated Management Of The Bagmati River Corridor, Lauren Platman
From Holy To Holistic: Working Towards Integrated Management Of The Bagmati River Corridor, Lauren Platman
Independent Study Project (ISP) Collection
The Bagmati and its tributaries have been an integral part of the Kathmandu Valley civilization. The river not only became a source of sustenance for the Valley's population but also gained religious-cultural significance. However, rapid urbanization and increasing industrial activities have transformed this once pristine river into an open sewer. Governmental organizations, NGOs, and community members are working towards improving the conditions of the Bagmati River through restoration projects and public awareness campaigns. Because of the large number of actors, collaboration on projects is vital in order to avoid duplication or conflict. After nearly thirty years of failed restoration projects …
