Geochemistry And Inorganic Carbon Transport Of A Glacial Till Drumlin At A Road Salt Facility, Houbao Li Sep 2013

Geochemistry And Inorganic Carbon Transport Of A Glacial Till Drumlin At A Road Salt Facility, Houbao Li

Open Access Dissertations

Investigations were conducted at a salt/premix storage facility lying on top of a glacial drumlin near the coastline in eastern Massachusetts, to characterize salt contaminated groundwater. Groundwater hydrogeochemical variations at different depths were determined based on ten years of monthly or quarterly water quality data from 54 monitoring wells. Groundwater was grouped in three water categories – shallow, middle and deep. Hydrogeochemical characterization indicates that the dominant water types are Na-Cl, Na-Ca-Cl and Ca-HCO3 from the shallow to deep water group. Rock weathering is the dominant hydrogeochemical process for deep water group, whereas salt water percolation and cation exchange control …


Sustainable Water Management Using Environmental Flows In The Connecticut River, Alec Bernstein May 2013

Sustainable Water Management Using Environmental Flows In The Connecticut River, Alec Bernstein

Environmental & Water Resources Engineering Masters Projects

There is significant evidence demonstrating that altering river flows downstream of impoundments harms native aquatic ecosystems and decreases the ability of native species to strive and survive. Innovative water management practices are needed to improve the health of native aquatic species and their surrounding ecosystems while maintaining the benefits from historic operating policies at these facilities. The impacts of individual reservoir operations on ecosystem health are often masked by the compounding influence of multiple upstream impoundments, making it difficult to analyze an individual facility’s impact within the larger system. This study presents an optimization model that investigates the value of …


Using Ce-Qual-W2 To Model A Contaminant Spill Into The Wachusett Reservoir, Lillian M. Clark Feb 2013

Using Ce-Qual-W2 To Model A Contaminant Spill Into The Wachusett Reservoir, Lillian M. Clark

Environmental & Water Resources Engineering Masters Projects

This research was done to understand the potential fate and transport of a contaminant spill into the Wachusett Reservoir utilizing the model CE-QUAL-W2 V3.6. The Wachusett Reservoir, located in central Massachusetts, is the main water supply for the Boston, MA metropolitan area. The reservoir has a capacity of approximately 65 billion gallons and receives about half of its total inflow from the Quabbin Reservoir, which has a capacity of 412 billion gallons. Water is transferred from the Quabbin Reservoir to the western end of the Wachusett Reservoir intermittently through the Quabbin Aqueduct typically from June through November to meet higher …

University Of Massachusetts Amherst 2012-2021 Capital Improvement Projects, Douglas Vigneau, Juanita Holler, University Of Massachusetts Building Authority, John Mathews, Ludmilla Pavlova-Gillham, Ezra Small

Campus Planning Master Plans

In 2013 the University of Massachusetts, on behalf of the University of Massachusetts Building Authority and Massachusetts Division of Capital Asset Management and Maintenance (DCAMM), submitted an Expanded Environmental Notification Form for the University's 2012 - 2021 Capital Improvement Plan to the Executive Office of Energy and Environmental Affairs (EOEEA) Massachusetts Environmental Policy Act Office (MEPA).

Taken individually, the majority of the Projects, comprising of 13 building/space, 7 site/landscape, and 5 facility/ utility scale improvement projects, do not require MEPA review as most of the Project sites are confined to infill areas on campus that are currently or …


Umass Amherst Green Building Guidelines 2013, Ludmilla Pavlova-Gillham, Ted Mendoza, Ezra Small, Patricia O'Flaherty, Nariman Mostafavi, Mohamed Farzinmoghadam, Somayeh Tabatabaee Pozveh Jan 2013

Umass Amherst Green Building Guidelines 2013, Ludmilla Pavlova-Gillham, Ted Mendoza, Ezra Small, Patricia O'Flaherty, Nariman Mostafavi, Mohamed Farzinmoghadam, Somayeh Tabatabaee Pozveh

Campus Planning Reports and Plans

Facilities & Campus Services, Sustainable UMass and Campus Planning support sustainability and energy conservation initiatives by providing in-house resources to campus staff as well as designers and contractors working with the University. The UMass Amherst Green Building Guidelines provide a framework for approaching new construction and major renovation projects at UMass Amherst that are undergoing LEED certification by focusing the conversation on green building aspects that are most important to the campus. They are intended to be the beginning of a dynamic conversation between designers, environmental consultants and constructors, university stakeholders, and users of new high performance buildings.
