Consumer electronic devices (CEDs) contain toxic materials including heavy metals and brominated flame retardants that can pose a threat to public and environmental health if improperly disposed Recent legislation enacted in the European Union and introduced in California bans the sale of CEDs containing these toxics. As a result, manufacturers need to change the design of their products to reduce the environmental impact, yet little is known about consumer willingness to pay for these "green" products. We estimate willingness to pay higher prices for environmentally friendly desktop computers by California households and find that most are willing to pay only 1% higher retail prices for "green" PCs. Other key demographic characteristics include age, income, and education. environmental attitudes and beliefs are also important. © 2006 IEEE.

The transformation of the steroidal Endocrine Disrupting Compounds (EDCs), 17-®- estradiol (E2) and 17-ethinyl estradiol (EE2) by direct UV photolysis and UV/H2O2 advanced oxidation was studied from the perspective of the removal of estrogenic activity associated with the compounds. First, experiments were performed to link the oxidation of E2 and EE2 with subsequent reduction in estrogenic activity. No statistically significant difference between these rates was observed, implying that the oxidation products of E2 and EE2 are not as estrogenic (as measured by the YES) as the parent compounds. Utilizing the YES, 90% removal of estrogenic activity of E2 and EE2 at environmentally relevant concentrations (~3g L-1) was achieved using a combination of 5 mg L-1 H2O2 and a UV dose of less than 400 mJ cm-2. Thus, these compounds, when considered at environmentally relevant levels, j are significantly degraded at much lower UV doses than previously thought. A steady state OH radical model was used to predict oxidation of EE2 in the laboratory water. © 2006 American Water Works Association WQTC Conference All Rights Reserved.

In the United States, 25% of existing and 33% of newly developed homes use decentralized or onsite systems. They are now recognized as a permanent component of our nation's wastewater infrastructure. The performance of onsite and clustered (decentralized) wastewater treatment systems is a national issue of great concern to the U.S. environmental Protection Agency (EPA). According to the EPA, "adequately managed decentralized systems that protect the environment and public health can provide an alternative to centralized wastewater treatment systems." Today, many wastewater treatment technologies and wastewater management systems are available, providing a low-cost alternative to conventional sewers. Unfortunately, many of these systems are improperly managed and do not meet public health and water quality goals. As technology innovations occur, the complexity of systems increase, resulting in a greater need for automated monitoring and control systems. Real-time monitoring is emerging as a key element and stable component to process and overall system management. Based on the process paradigm of "Centralized Management of Decentralized Wastewater Systems," this project explored the possibility of monitoring multiple systems from a central location. The primary objective of this project is to test and evaluate the applicability of the need for this "centralized paradigm" in the context of managing onsite systems distributed and located in different sites. However, the single focus of this paper is to illustrate the framework and architecture of this design and its implementation. Specific information presented in this paper includes: software and hardware requirements for real-time monitoring and the architecture of data collection from the remote site to the desktop (acquisition, transmission, storage, and analysis of data).

The paper focuses on the improvements to engineered features of a passive technology that has been used for remediation of acid rock drainage (ARD). This passive remedial technology, a sulfate-reducing bacteria (SRB) bioreactor, takes advantage of the ability of SRB that, if supplied with a source of organic carbon, can increase pH and alkalinity of the water and immobilize metals by precipitating them as metal sulfides or hydroxides. The remoteness of ARD sites and their abundance require that the design of an SRB bioreactor be simple and inexpensive. Therefore, bioreactors need to be designed to a size that allows for transportation using primitive roads. To satisfy these requirements a design for a modular treatment system was developed using reactive cartridges (RC) that are prefabricated as 2.44-meter diameter vessels. The RC has been designed so it supports the prime functional aspects of a bioreactor such as high permeability, ample supply of organic carbon, ability to maintain anaerobic conditions, and capacity to accumulate precipitated metals and means for their periodical removal, as needed. In addition, the configuration of the RC allows for an easy replacement of the organic carbon. The RCs can be transported to an ARD site and assembled into a treatment system with a number of modules as required by the ARD flow rate and the metals load. A bioreactor system consisting of four RCs will be installed at an abandoned mine site with ARD of pH 5 or lower and a significant load of metals. The process of site selection is in progress. The RC design was developed by the Mine Waste Technology program (MWTP) at MSE Technology Applications (MSE), Butte, Montana, USA. The work was funded by the U.S. environmental Protection Agency (EPA) and was jointly administered by the EPA and the U.S. Department of Energy (DOE) National Energy Technology Laboratory and performed at the Western environmental Technology Office under DOE contract number DE-AC09-96EW96405.

Public health is an increasingly important issue for environmental engineers, as indicated by the ABET 2005-2006 accreditation guidelines. An environmental Health for Developing Communities course was developed as part of the new engineering for Developing Communities (EDC) option for environmental / Civil engineering students at the University of Colorado at Boulder (CU). This course provides students with a basic understanding of environmental health issues, methods, and practices through an emphasis on their application in developing communities worldwide. The course emphasizes sustainable approaches for improving public health and the importance of interdisciplinary collaboration between practitioners of public health, the environmental sciences, and engineering. The course was piloted for the first time in Spring 2005 to eight graduate students. Semester-long team projects were associated with existing Engineers Without Borders (EWB) - CU projects in Peru, Mali, and Rwanda. The students identified the major health problems in the community, indicated engineering solutions that would improve these, and prioritized the health problems and solutions with regards to costs and benefits. Feedback from the students and instructors was gathered via a mid-term questionnaire, end of semester surveys, and the traditional Faculty Course Questionnaire (FCQ) administered by CU. In the future, the course will be cross-listed as an undergraduate course and dual-listed for environmental Studies majors. © American Society for engineering Education, 2006.
