This study investigates the feasibility and benefits of transferring data between Autodesk Revit (used for building information modeling (BIM)) and BUILDER SMS (used for sustainable facility management (SFM)). Two data transfer methods were evaluated using a case study; one involved entirely manual data transfer, the other a combination of manual and automatic. Of the data transfer methods evaluated, the manual/automated hybrid was determined to be the best option, especially when regular updates are envisioned. The case study produced an enhanced BIM model that can be used to support sustainable facility management, called here an SFM-enhanced BIM model. An integration workflow is proposed for efficiently creating future SFM-enhanced BIM models. A focus group of facilities management professionals evaluated the case study BIM model. The focus group was most interested in the visualization capabilities—e.g., filtered views for condition assessments—and the ability to view the BIM model on a tablet/mobile device during on-site operation and maintenance activities.

Subsurface fires and smoldering events at landfills can present serious health hazards and threats to the environment. These fires are much more costly and difficult to extinguish than open fires at the landfill surface. The initiation of a subsurface fire may go unnoticed for a long period of time and undetected fires may spread over a large area. Unfortunately, not all landfill operators keep or publish heat elevation data and many landfills are not equipped with a landfill gas extraction system to control subsurface temperatures generated from the chemical reactions within. The timely and cost‐effective identification of subsurface fires is an important and pressing issue. In this work, we describe a method for using satellite thermal infrared imagery at a moderate spatial resolution to identify the locations of subsurface fires and monitor their migration within landfills. The focus of this study was the Bridgeton Sanitary Landfill in Bridgeton, MO, USA where a subsurface fire was first identified in 2010 and continues to burn today. Observations from Landsat satellites over the last seventeen years were examined for surface temperature anomalies (or hot spots) that may be associated with subsurface fires. The results showed that the locations of hot spots identified in satellite imagery match the known locations of the subsurface fires. Changes in the hot‐spot locations with time, as determined by in situ measurements, correspond to the spreading routes of the subsurface fires. These results indicate that the proposed approach based on satellite observations can be used as a tool for the identification of landfill subsurface fires by landfill owners/operators to monitor landfills and minimize the expenses associated with extinguishing landfill fires.

Subsurface temperature is a critical indicator for the identification of the risk associated with subsurface fire hazards in landfills. Most operational landfills in the United States (US) have experienced exothermic reactions in their subsurface. The subsurface landfill area is composed of various gases generated from chemical reactions inside the landfills. Federal laws in the US mandate the monitoring of gases in landfills to prevent hazardous events such as landfill fire breakouts. There are insufficient investigations conducted to identify the causes of landfill fire hazards. The objective of this research is to develop a methodological approach to this issue. In this study, the relationship was investigated between the subsurface elevated temperature (SET) and soil gases (i.e., methane, carbon dioxide, carbon monoxide, nitrogen, and oxygen) with the greatest influence in landfills. The significance level of the effect of soil gases on the SET was assessed using a decision tree approach. A naïve Bayes technique for conditional probability was implemented to investigate how different gas combinations can affect different temperature ranges with respect to the safe and unsafe states of these gases. The results indicate that methane and carbon dioxide gases are strongly associated with SETs. Among sixteen possible gas combinations, three were identified as the most probable predictors of SETs. A three-step risk assessment framework is proposed to identify the risk of landfill fire incidents. The key findings of this research could be beneficial to landfill authorities and better ensure the safety of the community health and environment.

The purpose of this study was to investigate the impact of an engineering living and learning community (ELC) on first-year engineering students. A control group of non-ELC students was used to compare the experiences of the ELC participants. Analysis of survey data showed that there was significant differences between the ELC students and the non-ELC students in how they responded to questions regarding social support, academic support, connectedness to campus, and satisfaction with the College of Engineering and the institution as a whole. Particularly, there were significant differences between ELC and non-ELC students for questions related to feeling like part of an engineering community, having strong relationships with peers, belonging to a supportive peer network, studying with engineering peers, and spending time with classmates outside of class.

Biogeochemical reductive dechlorination (BiRD) uses biotically generated iron sulphide minerals to abiotically reduce chlorinated aliphatic hydrocarbons (CAH). BiRD was applied by permeable reactive barrier (PRB) at Dover Air Force Base, the first time this approach was tested in the field. Iron sulphide minerals were generated in trenches filled with iron rich sand (iron), mulch (organic), mineral gypsum (sulphate), and limestone (pH control). For comparison purposes, trenches were also filled with sand, mulch, and limestone to create conditions favourable to biostimulation. Compared to biostimulation, BiRD showed little evidence of methanogenesis, indicating that the reductive capacity of the applied organic was converted to mineral iron sulphide rather than methane. CAH treatment in the biostimulation PRB appeared to be incomplete after 150 days, apparently stalling at DCE. In comparison, for the BiRD treatment area, CAH treatment appeared to be rapid and reduced PCE, TCE and DCE levels within the 150 day time period.

A waste is anything humans do not want. Solid wastes are unwanted items that are not liquid or gas. Waste disposal involves removing a waste from the human sphere. This is often done by placing the waste in a landfill or burning it and placing the ashes in a landfill. Recycling involves processing a waste for use in manufacturing a new product. Reusing waste means using it again, either directly or after repair or improvement. Finally, source reduction involves not making waste in the first place.

Engineering educators have typically used non-living systems or products to demonstrate engineering principles. Each traditional engineering discipline has its own products or processes that they use to demonstrate concepts and principles relevant to the discipline. In recent years engineering education has undergone major changes with a drive to incorporate sustainability and green engineering concepts into the curriculum. As such an innovative initiative has been undertaken to use a living system such as an aquarium to teach basic engineering principles. Activities and course content were developed for a freshman engineering class at Rowan University and the Cumberland County College and K-12 outreach for the New Jersey Academy for Aquatic Sciences. All developed materials are available on a dynamic website for rapid dissemination and adoption.

In December 2001, 2225 tonnes of fluidized bed combustion (FBC) ash were injected into an abandoned coal mine in eastern Oklahoma. Post-injection monitoring continued for 24 months, during which the mine system appeared to be reestablishing equilibrium with CO2 in the mine headspace. Alkalinity and pH gradually increased, and as of December 2003 were roughly 65 ppm and 7.3, respectively. Metal concentrations were still significantly lower than pre-injection levels, but iron and manganese concentrations had increased from non-detect levels shortly after injection to roughly 30 ppm and 1.25 ppm, respectively. Aluminum, nickel, and zinc were less than pre-injection concentrations and did not appear to be increasing (roughly

Biogeochemical reductive dechlorination (BiRD) is a new remediation approach for chlorinated aliphatic hydrocarbons (CAHs). The approach stimulates common sulfate-reducing soil bacteria, facilitating the geochemical conversion of native iron minerals into iron sulfides. Iron sulfides have the ability to chemically reduce many common CAH compounds including PCE, TCE, DCE, similar to zero valent iron (Fe0). Results of a field test at Dover Air Force Base, Dover, Delaware, are given in this paper. BiRD was stimulated by direct injection of Epson salt (MgSO4·7H2O) and sodium (L) lactate (NaC3H5O3) in five injection wells. Sediment was sampled before and 8 months after injection. Significant iron sulfide minerals developed in the sandy aquifer matrix. From ground water analyses, treatment began a few weeks after injection with up to 95% reduction in PCE, TCE, and cDCE in less than 1 year. More complete CAH treatment is likely at a larger scale than this demonstration.

Aqueous and mineral intrinsic biodegradation assessment (AMIBA) relies on the measurement of iron and sulfur mineral species, in addition to standard water analyses, to evaluate the intrinsic bioremediation component of natural attenuation. AMIBA can be used to: (1) assess the contribution of various biodegradation processes; (2) quantify the efficiency of biodegradation; (3) determine an overall depletion rate for hydrocarbon plume and source; (4) estimate future capacity for biodegradation; and (5) indirectly demonstrate plume contraction. The purpose of this paper is to introduce AMIBA to practitioners, focusing on sample collection and data interpretation. Results from three sites are also presented, illustrating different conditions and outcomes. At each site multiple soil borings were installed and sampled at multiple depths. Contaminants, mineral Fe(II) and Fe(III) , mineral sulfide (as FeS and FeS2 ), nitrate, oxygen, and sulfate analyses were conducted on sediment and/or groundwater. AMIBA was used to estimate as much as 96% contaminant destruction and estimates of depletion rates could also be determined. Oxygen was never the principle electron acceptor linked to contaminant degradation. Iron and sulfate are consistently dominant electron acceptors except at one site where nitrate was present due to human activities.

This paper details investigations of the feasibility of wastewater reuse in Gloucester County, New Jersey. Wastewater can be a valuable resource in cities or towns where population is growing and water supplies are limited. In addition to easing the strain on limited freshwater supplies, the reuse of wastewater can improve the quality of streams and lakes by reducing the effluent discharges and loading that they receive. Wastewater may be reclaimed and reused for crop and landscape irrigation, groundwater recharge, or recreational purposes. Reclamation for drinking is technically possible, but this reuse faces significant public resistance. Wastewater reuse can also reduce the demand on valuable and diminishing potable water supplies and possibly save money for the costly investment of new water sources and supplies.

A demonstration project was conducted to investigate treating acid mine water by alkaline injection technology (AIT). A total of 379 t of alkaline coal combustion byproduct was injected into in an eastern Oklahoma drift coal mine. AIT increased the pH and alkalinity, and reduced acidity and metal loading. Although large improvements in water quality were only observed for 15 months before the effluent water chemistry appeared to approach pre-injection conditions, a review of the data four years after injection identified statistically significant changes in the mine discharge compared to pre-injection conditions. Decreases in acidity (23%), iron (18%), and aluminum (47%) were observed, while an increase in pH (0.35 units) was noted. Presumably, the mine environment reached quasi-equilibrium with the alkalinity introduced to the system.

Biogeochemical reductive dechlorination (BiRD) is a newly recognized method for the remediation or natural attenuation of chlorinated solvents. Chlorinated solvents are rapidly treated by abiotic reaction with reduced mineral iron sulfides. Iron sulfides are formed by naturally occurring sulfate-reducing bacteria when sufficient SO42− and organic carbon are present or supplied to sediments containing mineral iron. An example of site characterization focusing on BiRD is presented focusing on mineral phases. Methods demonstrated here may be employed at other sites to evaluate naturally occurring BiRD or to evaluate an engineered BiRD remediation. A field investigation was performed at a TCE contaminated site at Altus AFB with naturally high concentrations of SO42− and Fe(III) minerals and where an accidental fuel spill provided organic carbon. In the area of this fuel spill significant mineral iron sulfides were found, sulfate was almost completely removed, and TCE was absent. Only small amounts of daughter products were found, further indicating that the BiRD pathway was operative. Mass balance data indicates all of the remaining TCE (182 kg) could be treated by the remaining FeS (66.5 kg) in the upper aquifer; however, the FeS was not co-located with TCE to enable complete reaction. Laboratory microcosm tests with FeS amended and FeS-rich sediment from Altus AFB also suggest that BiRD is capable of destroying TCE. The results suggest that an engineered BiRD treatment is possible for this site.

In 1994 a demonstration project was undertaken to investigate the effectiveness of using CCBs for the in situ treatment of acidic mine water. Actual injection of alkaline material was performed in 1997 with initial positive results; however, the amount of alkalinity added to the system was limited and resulted in short duration treatment. In 1999, a CBRC grant was awarded to further investigate the effectiveness of alkaline injection technology (AIT). Funds were released in fall 2001. In December 2001, 2500 tons of fluidized bed combustion (FBC) ash were injected into the wells used in the 1997 injection project. Post injection monitoring continued for 24 months. During this period the mine chemistry had gone through a series of chemical changes that manifested as stages or ''treatment phases.'' The mine system appeared to be in the midst of reestablishing equilibrium with the partial pressure of mine headspace. Alkalinity and pH appeared to be gradually increasing during this transition. As of December 2003, the pH and alkalinity were roughly 7.3 and 65 ppm, respectively. Metal concentrations were significantly lower than pre-injection levels, but iron and manganese concentrations appeared to be gradually increasing (roughly 30 ppm and 1.25 ppm, respectively). Aluminum, nickel, and zincmore » were less than pre-injection concentrations and did not appear to be increasing (roughly

An approach to evaluating intrinsic bioremediation, aqueous and mineral intrinsic biodegradation assessment (AMIBA) is described. AMIBA is based on the microbial reduction of Fe3+ and SO42-, forming reduced Fe and S mineral species in amounts stoichiometrically equivalent to the contaminant mass oxidized by microbial processes. Mineral data from sediment cores are emphasized rather than the aqueous data used in existing protocols. AMIBA was demonstrated at Westover Air Force Base, Chicopee, Massachusetts. Over 300 times more reduced Fe2+ was in mineral form, compared to aqueous. The distribution of mineral Fe3+ and Fe2+ marked the historic extent of the plume, confirming plume retreat. Aqueous SO42- reduction resulted in the deposition of equivalent amounts of iron sulfide minerals near the source area. The total mass of fuel degraded by intrinsic bioremediation and the rate of source depletion was estimated. Thus, the past and future performance of intrinsic bioremediation was assessed using one sampling event rather than relying on protracted monitoring, as is the current practice.

Environmental engineering education at universities is a rapidly changing field globally. Traditionally it has resided in the civil engineering program addressing water and wastewater quality, treatment, design and regulatory issues. In recent years environmental engineering has become a much broader field encompassing water, wastewater, soil pollution, air pollution, risk assessment, ecosystems, human health, toxicology, sustainable development, regulatory aspects and much more. The need to introduce environmental engineering/green engineering/pollution prevention/design for the environment concepts to undergraduate engineering students has become recognized to be increasingly important. This need is being driven in part through the US Engineering Accreditation Commission Accreditation Board for Engineering and Technology criteria 2000. Thus there has been a major shift in environmental engineering education and it no longer resides only within the civil engineering discipline. This paper focuses on the development of innovative curricula for a brand new engineering program at Rowan University that integrates environmental education for all engineers. A common course known as "engineering clinic" was developed for all engineering students throughout their eight semesters of engineering education. One of the clinic goals is to integrate engineering design and the environment. The program, in its seventh year, indicates successful implementation of environmental education in all four engineering disciplines in their course work and clinics.

Coal combustion by-products (CCBs) have beneficial properties that are currently underutilized. Prudent evaluation of CCBs prior to alternative use application is in the best interest of the party undertaking the project. Ignorance and misunderstanding can lead to environmental harm and may result in unnecessary obstacles and undue regulation. With this consideration in mind, an alkaline injection treatment (AIT) evaluation was undertaken in order to select the most appropriate CCB to treat acid mine drainage (AMD). The information generated from this study also provides insight to the suitability of the CCBs for such alternative uses as neutralization of acidic industrial wastes and soil liming applications in an agricultural setting. Although there is variability in CCB composition due to parent material and operating conditions, general patterns are apparent from this work. With respect to AIT, CCBs with high alkaline contents, nonsetting characteristics, and low exchangeable toxic constituents are the most effective and desirable.
