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 …
Increased Effluent Dosage Effects On Septic System Absorption-Field Products Of Differing Architecture Types, Andrew Richard Gibbons
Increased Effluent Dosage Effects On Septic System Absorption-Field Products Of Differing Architecture Types, Andrew Richard Gibbons
Graduate Theses and Dissertations
Nationwide, approximately 20% of all homes use an on-site septic system as a form of household wastewater treatment. Since karst features are prevalent throughout the Ozark Highlands region of Northwest Arkansas, surface and groundwater resources are susceptible to contamination. Therefore, the objectives of this study were to evaluate the effects of soil condition (i.e., wet and dry) and absorption-field-product architecture type [i.e., chamber, gravel-less-pipe (GLP), polystyrene-aggregate (PSA), and pipe-and-aggregate (PA)] on in-product solution storage and biomat thickness in a profile-limited soil, and to identify the long-term acceptance rate (LTAR) of each product. During Phase I of this study (i.e., March …

Daugherty Water for Food Global Institute: Faculty Publications
Our specific focus in this book is on securing water for sustainable food production. This links to sustainable water resources management, delivering on the water supply and sanitation requirements and provisioning water for energy and the urban sector. A specific intent is to ensure that the realities in low- and middle-income countries in Africa and Asia are recognized and to provide practical pathways to change that fit these realities and the aspirations of those countries. This will help to prepare for the next step in the SDG [sustainable development goals] process: devolving the SDGs to the national level. It will …
Study On Investment In Water And Wastewater Infrastructure And Economic Development, Edward J. Collins, Jr. Center For Public Management, University Of Massachusetts Boston
Study On Investment In Water And Wastewater Infrastructure And Economic Development, Edward J. Collins, Jr. Center For Public Management, University Of Massachusetts Boston
Edward J. Collins Center for Public Management Publications
The Edward J. Collins, Jr. Center for Public Management in the John W. McCormack Graduate School of Policy and Global Studies at the University of Massachusetts Boston was tasked by the Massachusetts Water Resources Authority Advisory Board (MWRAAB) with asking and answering a very fundamental question relating to public infrastructure: “What is the relationship between investment in water and wastewater infrastructure and economic growth?” To do so, Center staff not only researched the positive results of investing in infrastructure, but also took time to consider what failing to invest in adequate water and wastewater infrastructure might mean. Additionally, the Center …
