Description
Since its launch by the US Green Building Council (USGBC), Leadership in Energy and Environmental Design (LEED) certification has been postured as the "gold standard" for environmentally conscious, sustainable building design, construction and operations. However, as a "living measurement", one which requires ongoing evaluation and reporting of attainment and compliance with LEED certification requirements, there is none. Once awarded, LEED certification does not have a required reporting component to effectively track continued adherence to LEED standards. In addition, there is no expiry tied to the certification; once obtained, a LEED certification rating is presumed to be a valid representation of project certification status. Therefore, LEED lacks a requirement to demonstrate environmental impact of construction materials and building systems over the entire life of the project. Consequently, LEED certification is merely a label rather than a true representation of ongoing adherence to program performance requirements over time. Without continued monitoring and reporting of building design and construction features, and in the absence of recertification requirements, LEED is, in reality, a gold star rather than a gold standard. This thesis examines the lack of required ongoing monitoring, reporting, or recertification requirements following the award by the USGBC of LEED certification; compares LEED with other international programs which do have ongoing reporting or recertification requirements; demonstrates the need and benefit of ongoing reporting or recertification requirements; and explores possible methods for implementation of mandatory reporting requirements within the program.

Description
In 2009, cap and trade was at the forefront of political and environmental discussions. At this time, the American Clean Energy and Security Act passed in the United States House of Representatives. Market based systems are alternatives to traditional regulatory methods such as command and control. This study intended to assess the attitudes of environmental leaders who managed air emissions as a part of their job responsibilities. The attitude of these individuals would have influenced their acceptance of this method as a program to reduce environmental pollution and improve air quality. The purpose of this study was to evaluate the attitudes of South Carolinian Title V environmental leaders toward cap and trade. Additionally, the study intended to determine if experience impacted the attitudes of survey respondents. Lastly, the study determined if environmental leaders found current methods such as command and control effective in air pollution regulation. The survey used the Likert Method of Summated Ratings. Environmental leaders reviewed attitudinal statements about the various subjects. The leaders selected an agreement level which determined their attitudes toward the statement. Numerical response ratings evaluated the leader's attitude by experience level. The survey found that respondents had negative attitudes toward cap and trade. The respondents had a positive attitude toward traditional regulatory methods such as command and control. Lastly, the results concluded that environmental experience did not have an impact on the respondents' attitude toward cap and trade. Therefore, it can be concluded that the environmental leaders prefer traditional air pollution regulatory methods in comparison to alternatives such as cap and trade.

Description
Pharmaceutical and Personal Care Products (PPCPs) are a large, diverse group of emerging contaminants comprised of pharmaceuticals, plasticizers, detergents, and insecticides. Studies have shown that PPCPs are entering aquatic environments, wastewaters, and water supplies. The occurrence of these PPCPs has generated concern resulting in proposed federal legislation that could require control, monitoring, and treatment of Pharmaceutical and Personal Care Products by Publicly Owned Treatment Works (POTWs). This study evaluated the potential financial impact this proposed legislation could have on U.S. POTWs using City of Mesa, Arizona as a model POTW. The current laws concerning PPCPs as well as the proposed legislation were described. The proposed federal legislation would create investigational studies about PPCPs. The studies could lead to regulations concerning the control, monitoring, and treatment of PPCPs by POTWs. The potential financial costs of the following strategies were assessed: multiple barriers concept for PPCP control or prevention programs by POTWs, PPCP monitoring of wastewater, and upgrading POTW treatment technology for PPCP removal. Study results found no new wastewater treatment technologies were economically suitable for POTWs, however, community education and programs such as Household Take-back programs could be financially viable.

Description
The goal of the study was twofold: (i) to investigate the synthesis of hematite-impregnated granular activated carbon (Fe-GAC) by hydrolysis of Fe (III) and (ii) to assess the effectiveness of the fabricated media in removal of arsenic from water. Fe-GAC was synthesized by hydrolysis of Fe(III) salts under two Fe (III) initial dosages (0.5M and 2M) and two hydrolysis periods (24 hrs and 72 hrs). The iron content of the fabricated Fe-GAC media ranged from 0.9% to 4.4% Fe/g of the dry media. Pseudo-equilibrium batch test data at pH = 7.7±0.2 in 1mM NaHCO3 buffered ultrapure water and challenge groundwater representative of the Arizona Mexico border region were fitted to a Freundlich isotherm model. The findings suggested that the arsenic adsorption capacity of the metal (hydr)oxide modified GAC media is primarily controlled by the surface area of the media, while the metal content exhibited lesser effect. The adsorption capacity of the media in the model Mexican groundwater matrix was significantly lower for all adsorbent media. Continuous flow short bed adsorber tests (SBA) demonstrated that the adsorption capacity for arsenic in the challenge groundwater was reduced by a factor of 3 to 4 as a result of the mass transport effects. When compared on metal basis, the iron (hydr)oxide modified media performed comparably well as existing commercial media for treatment of arsenic. On dry mass basis, the fabricated media in this study removed less arsenic than their commercial counterparts because the metal content of the commercial media was significantly higher.

Description
Traditional methods of environmental regulation and enforcement have been questioned over the last decade. Due to the number of environmental regulations, and subsequent cost of enforcement, governments have begun to incentivize the adoption of environmental management systems (EMSs). These management systems encourage companies to better manage their environmental performance voluntarily. It is the purpose of this study to list the types of government incentives that have been used and categorize them into three groups based off of their characteristics. Ten incentive types were identified and put into three categories; (a) reducing the barriers to EMS adoption; (b) enhancing benefits derived from EMS adoption, and (c) rewarding EMS implementers with reduced enforcement. The research shows that each category of incentives encourages different manufacturing facilities to adopt EMSs. Using data from previously conducted case studies and surveys to determine what type of manufacturing facilities are affected, this study finds that government incentives have been shown to have a measurable impact on the decision makers of manufacturing facilities to adopt an EMS. The study concludes that a combination of traditional environmental regulation used with targeted incentives provide the most efficient use of resources by governments.

Description
The following research is a regulatory and emissions analysis of collocated sources of air pollution as they relate to the definition of "major, stationary, sources", if their emissions were amalgamated. The emitting sources chosen for this study are seven facilities located in a single, aggregate mining pit, along the Aqua Fria riverbed in Sun City, Arizona. The sources in question consist of Rock Crushing and Screening plants, Hot Mix Asphalt plants, and Concrete Batch plants. Generally, individual facilities with emissions of a criteria air pollutant over 100 tons per year or 70 tons per year for PM10 in the Maricopa County non-attainment area would be required to operate under a different permitting regime than those with emissions less than stated above. In addition, facility's that emit over 25 tons per year or 150 pounds per hour of NOx would trigger Maricopa County Best Available Control Technology (BACT) and would be required to install more stringent pollution controls. However, in order to circumvent the more stringent permitting requirements, some facilities have "collocated" in order to escape having their emissions calculated as single source, while operating as a single, production entity. The results of this study indicate that the sources analyzed do not collectively emit major source levels of emissions; however, they do trigger year and daily BACT for NOx. It was also discovered that lack of grid power contributes to the use of generators, which is the main source of emissions. Therefore, if grid electricity was introduced in outlying areas of Maricopa County, facilities could significantly reduce the use of generator power; thereby, reducing pollutants associated with generator use.

Description
The purpose of drinking water regulations is to keep our drinking water safe from contaminants. This research reviewed federal regulation including the Contaminant Candidate List (CCL) regulatory process, the public health effects of six nitrosamines in drinking water, analyzes of occurrence data from Unregulated Contaminant Monitoring Rule (UCMR 2) and suggests how nitrosamines can be regulated. Currently only total trihalomethanes (THM) and haloacetic acids (HA) are regulated at the federal level. However, California has notification action levels and Massachusetts has guidelines of 10 ng/L for nitrosamine concentration. Nitrosamine data collected under the UCMR 2 were analyzed to assess the occurrence and the effect of disinfectant type and source water type. The data showed that N-nitrosodimethylamine (NDMA) was detected in drinking water at concentrations higher than the minimum reporting level (MRL) of 2 ng/L. Four nitrosamines including N-nitroso-diethylamine (NDEA), N-nitroso-di-n-butylamine (NDBA), N-nitroso-methylethylamine (NMEA) and N-nitroso-pyrrolidine (NPYR) and very low detections. N-nitroso-di-n-propylamine (NDPA) was not detected in the sample analyses. NDMA was primarily detected in public water systems using chloramines other than chlorine.

Description
With increasing interest in sustainability and green building, organizations are implementing programs such as Leadership in Energy and Environmental Design for Existing Buildings: Operations and Maintenance (LEED-EB) in order to focus corporate sustainability goals on the operations of a facility and the practices of the building occupants. Green building programs help reduce the impact of a facility and bring about several environmental benefits including but not limited to energy conservation, water conservation and material conservation. In addition to various environmental benefits, green building programs can help companies become more efficient. The problem is that organizations are not always successful in their pursuits to achieve sustainability goals. It frequently take years to implement a program, and in many cases the goals for sustainability never come to fruition, when in the mean time resources are wasted, money is spent needlessly and opportunities are lost forever. This thesis addresses how the Six Sigma methodologies used by so many to implement change in their organizations could be applied to the LEED-EB program to help companies achieve sustainability results. A qualitative analysis of the Six Sigma methodologies was performed to determine if and how a LEED-EB program might utilize such methods. The two programs were found to be compatible and several areas for improvements to implementing a LEED-EB program were identified.

Description
Water quality is a severe problem throughout the world. Much available water is contaminated by pathogenic microbes. This project reviews the traditional process of solar water disinfection in bottles (SODIS), discusses experiments conducted with SODIS bottles modified to thermally enhance the process, analyzes experimental data for modified SODIS containers, and suggests ways that by which the traditional process can be improved. Traditional SODIS is currently used in many rural parts of developing countries to disinfect water. The process uses ultraviolet rays and thermal effects to inactivate microorganisms that tend to cause diarrheal disease. If a sufficiently high temperature is attained to reach a synergistic UV-thermal effect range, the process of SODIS is about three times faster. However, many factors can inhibit attainment of sufficient heating of water in SODIS bottles in practice. By modifying the bottles to enhance effectiveness of sunlight in increasing the temperature of the water, SODIS can be more effective. In this research, a series of experiments were conducted over a period of four months and15 days at Arizona State University Polytechnic campus in Mesa, Arizona, U.S.A. Four different types of inexpensive materials (black paint, white paint, foam insulation, and aluminized mylar) were used individually or in combination in seven different modified configurations to assess the potential of the modifications to increase the temperatures of water inside 2-liter PET bottles. Experiments were run in triplicate. Temperatures inside the bottles, along with yard temperature, were recorded over time. Graphs were plotted for each set of experiments. The results of these experiment show that several types of modifications increased water temperature during exposure to sunlight. Water in bottles with black paint and foam insulation on the back side attained the highest temperatures, approximately 8-10 degrees Celsius above temperatures attained in plain bottles. The results of these experiments show how several inexpensive, easily obtained materials can significantly enhance the SODIS process.

Description
The Toledo Core Based Statistical Area (CBSA) presents an interesting case study for the new sulfur dioxide (SO2) one hour standard. Since no SO2 monitor within 75 miles to estimate the attainment status of the area, American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) was used in this study to predict potential problems associated with the newly revised standard. The Toledo CBSA is home to two oil refineries, a glass making industry, several coal fired lime kilns, and a sulfuric acid regeneration plant, The CBSA 3 has coal fired power plants within a 30 mile radius of its center. Additionally, Toledo is a major Great Lakes shipping port visited by both lake and ocean going vessels. As a transportation hub, the area is also traversed by several rail lines which feed four rail switching yards. Impacts of older generation freighters, or "steamers", utilizing high sulfur "Bunker C" fuel oil in the area is also an issue. With the unique challenges presented by an SO2 one hour standard, this study attempted to estimate potential problem areas in advance of any monitoring data being gathered. Based on the publicly available data as inputs, it appears that a significant risk of non-attainment may exist in the Toledo CBSA. However, future on-the-books controls and currently proposed regulatory actions appear to drive the risk below significance by 2015. Any designation as non-attainment should be self-correcting and without need for controls other than those used in these models. The outcomes of this screening study are intended for use as a basis for assessments for other mid-sized, industrial areas without SO2 monitors. The results may also be utilized by industries and planning groups within the Toledo CBSA to address potential issues in advance of monitoring system deployment to lower the risk of attaining long term or perpetual non-attainment status.
