Title: Ecological impact of arsenic, chromium and lead from application of recovered screened material on Florida soils.
Creator: Scarlatos, Dimitrios., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D., College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description: Disposal of construction and demolition (C&D) debris is a major problem. During recycling operations, the debris is passed over screens, generating what is called Recovered Screened Material (RSM). Previous analyses of RSM indicated high arsenic (As) levels. Thus, RSM is disposed in landfills in spite of the fact that natural soils may contain As levels higher than the proposed concentrations for soil clean-up goals. RSM samples were collected and analyzed from seven C&D debris recycling...
Show moreDisposal of construction and demolition (C&D) debris is a major problem. During recycling operations, the debris is passed over screens, generating what is called Recovered Screened Material (RSM). Previous analyses of RSM indicated high arsenic (As) levels. Thus, RSM is disposed in landfills in spite of the fact that natural soils may contain As levels higher than the proposed concentrations for soil clean-up goals. RSM samples were collected and analyzed from seven C&D debris recycling facilities and from other sites. The average arsenic content found in RSM ranged between residential and industrial clean-up goals. Chromium and lead levels in RSM were very low. The RSM quality depends mainly on the waste stream. Recycling procedures do not have any major effect on the RSM. Arsenic levels in natural soils showed a wide variability. Almost half of the soil samples had an arsenic level comparable to that found in RSM.

Title: Farfield modeling of the Boynton Inlet plume using sulfur hexafluoride as tracer.
Creator: Pire-Schmidt, Joaquin., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: The analysis and modeling of the coastal farfield behavior of inlet discharge plumes is the key to understanding the fate of pollutants discharged into the ocean. These plumes disperse in chaotic and unpredictable patterns. Theoretical models are based on the average conditions and calibrated to the results of tracer studies. Data and models for freshwater discharges in coastal ocean systems are limited because of the lack of adequate tracers. On February, 2007, a tracer study was conducted...
Show moreThe analysis and modeling of the coastal farfield behavior of inlet discharge plumes is the key to understanding the fate of pollutants discharged into the ocean. These plumes disperse in chaotic and unpredictable patterns. Theoretical models are based on the average conditions and calibrated to the results of tracer studies. Data and models for freshwater discharges in coastal ocean systems are limited because of the lack of adequate tracers. On February, 2007, a tracer study was conducted on the Boynton Inlet, Florida, using sulfur hexafluoride (SF6) tracer. The objective of this study is to provide methods of analysis for the sample data collected during the experiment. The detected tracer concentrated in a bolus that migrated north of the inlet at velocities lower than predicted by the current data. The plume was successfully modeled with a Gaussian plume model, with 90% of the SF6 predictions having less than 4.6 pptr error.

Show moreThe purpose of this study was to develop a user-friendly mathematical model for prediction of daily, ground level ozone concentration in Palm Beach County, Florida. The focus of this project was to investigate the correlation between hourly ozone concentrations and pre-existing pollutant levels and meteorological data. An artificial neural network model was applied, involving a backpropagation algorithm and the tangent sigmoid as the transfer function. Surface meteorological data and upper air data such as pressure, temperature, dew point temperature, wind speed and wind direction were included in the model, along with the ozone concentration in the hour previous to the forecast. Based on the model results, the 8-hour average ozone concentration is to be forecasted. This will assist state and local air pollution officials in providing the general public with early notice of an impending air quality problem.

Creator: Rueckert, William A., Florida Atlantic University, Restrepo, Jorge I.
Abstract/Description: The objective is to develop a groundwater flow model of the Surficial Aquifer System in the area of Plantation, Broward County, Florida, using the U.S. Geological Survey MODFLOW code and to make a comparison between the use of two supplementary contaminant transport models: MODPATH code and the MT3D code. The advantages and limitations of the two solute transport models are described and an evaluation is made of their accuracy with respect to delineation of traveltime related to capture zones...
Show moreThe objective is to develop a groundwater flow model of the Surficial Aquifer System in the area of Plantation, Broward County, Florida, using the U.S. Geological Survey MODFLOW code and to make a comparison between the use of two supplementary contaminant transport models: MODPATH code and the MT3D code. The advantages and limitations of the two solute transport models are described and an evaluation is made of their accuracy with respect to delineation of traveltime related to capture zones of wells. Final results of the computer simulations indicate that this study area is sensitive to river bed hydraulic conductivity and the stress of the continuous pumping at a nearby wellfield. Therefore, a critical factor in selecting an appropriate flow model for delineating the traveltime-related capture zone of a well is a model which simplifies the flow system while still preserving hydrogeologic characteristics of the flow system.

Title: The effects of on-site sewage treatment and disposal systems on the relief canals of Indian River County, the St. Sebastian River, and the central Indian River lagoon.
Creator: Tarnowski, Marie E., Lapointe, Brian E., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description: Effluent from on-site sewage treatment and disposal systems (OSTDS) is generally known to impact groundwaters and surface waters with nitrogen (N) and phosphorus (P) and other contaminants. Little research has quantified this problem along the Indian River Lagoon (IRL), especially in Indian River County (IRC) where there are 26,660 active systems. This study assessed the effects of OSTDS on contamination of surface and groundwaters along three urbanized canals and the St. Sebastian River in...
Show moreEffluent from on-site sewage treatment and disposal systems (OSTDS) is generally known to impact groundwaters and surface waters with nitrogen (N) and phosphorus (P) and other contaminants. Little research has quantified this problem along the Indian River Lagoon (IRL), especially in Indian River County (IRC) where there are 26,660 active systems. This study assessed the effects of OSTDS on contamination of surface and groundwaters along three urbanized canals and the St. Sebastian River in IRC, all of which flow into the Central IRL. Multiple lines of evidence were used to define the source of the nutrient loadings including the novel approach of using the artificial sweetener, sucralose, as an indicator of human sewage impact. Results indicate that areas with high densities of OSTDS are contributing N to surface waters and elevating N:P ratios through submarine groundwater discharge and promoting eutrophication in the Central IRL.

Title: Risk of injection using reclaimed water for aquifer recharge using rotavirus as surrogate contaminant.
Creator: Phonpornwithoon, Pollop, Bloetscher, Frederick, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: Groundwater aquifers are precious resources that has been serving human consumption for many centuries. This resource is pristine in comparison with surface waters such as lakes and canals, however, as population grows exponentially so does the demand for groundwater and the need to study the potential of groundwater replenishment programs. The injection of treated water or wastewater into an aquifer is a method to protect this resource for current and future generations. Health concerns...
Show moreGroundwater aquifers are precious resources that has been serving human consumption for many centuries. This resource is pristine in comparison with surface waters such as lakes and canals, however, as population grows exponentially so does the demand for groundwater and the need to study the potential of groundwater replenishment programs. The injection of treated water or wastewater into an aquifer is a method to protect this resource for current and future generations. Health concerns would be expected since migration of water of “impaired quality” can affect the drinking water by contamination. Regulatory barriers resulting from the perceived risks of adverse health effects from pathogens such as viruses have limited the concept of this impaired water resources from being used for groundwater replenishment programs. The objective of this study is to examine the risk assessment using computational modeling with MODFLOW and MT3D groundwater transport simulation. The results from the simulation showed that after two years, the risk of contamination based on concentration contours from the injection well to the production wellfields for the City of Hollywood stabilized below 10- 6. The risk assessment provided important aspect to demonstrate the concept of using injection of treated water as an option for groundwater replenishment.

Show moreThe United States established the Environmental Protection Agency (EPA) to monitor and enforce compliance with environmental pollution standards through various programs and policies. One such policy, the Audit Policy, allows companies to voluntarily self-report violations to the Agency in exchange for elimination of certain penalties. Despite the policy, firms still incur large environmental penalties, thus indicating the need for better understanding of the policy. A necessary but not sufficient condition for penalty relief under the Audit Policy requires discovery of violations by an environmental audit or a compliance management system. This research explores the option of discovery by a compliance management system and examines the motivation of managers to invest in an environmental management system (EMS). The theory of reasoned action (TRA) argues that attitude and subjective norms precede intentions. I use this theory to investigate what factors cause a manager to invest in an environmental management system (EMS). Additionally, I examine whether environmental attitude, tolerance for ambiguity and willful blindness are antecedents to attitude towards an EMS. In this study, I develop and test a scale of the willful blindness construct and measure its impact on managerial decision-making. The willful blindness construct development produced a one-item measure. My results support all hypotheses except for the predicted link between tolerance for ambiguity and attitude.
