Environmental sustainability is an interdisciplinary field that integrates natural and social sciences, humanities, arts, and education in pursuit of balancing human needs and ecological well-being. Environmental professionals research the environmental impacts of human behaviors and what drives these outcomes. Environmental sustainability considers the role of humans in nature and often views humans as embedded within environmental systems.. Majors in Environmental Sustainability at Earlham will leave college ready to address complex environmental problems by identifying social-ecological linkages and causes from multiple perspectives, collecting data to analyze those problems, and proposing possible solutions in collaboration with others. The Major in Environmental Sustainability prepares students for this through a collection of multi-disciplinary courses and a core Environmental Sustainability course sequence that helps students to frame and link those diverse perspectives. In each core ...
The most comprehensive water policy analysis conducted on the High Plains region to date was the High Plains Ogallala Regional Aquifer Study completed in 1982. Twenty years later, we had a unique opportunity to compare the projections from this study with the changes that actually occurred over the past two decades. Specific comparisons were made for the area of western Kansas overlying the High Plains Aquifer. These comparisons revealed some significant differences in the status of the aquifer and in the regions economic development, relative to the predictions of the study. Most notably, contrary to the studys predictions, irrigated area did not decline precipitously, but rather continued to increase during the period. Despite large increases in irrigated area and production of more water-intensive crops, such as corn and alfalfa, both per-unit area and total water use declined over the 20 years. Differences in observed and projected results can be attributed to a variety of factors, ...
DALLAS - September 13, 2012) The Environmental Protection Agency has awarded the Oklahoma Office of the Secretary of Environment $2,059,773 to implement watershed based plans designed to control nonpoint source pollution and protect water quality. The funds will support the Oklahoma Nonpoint Source Management Plan in priority watersheds. Project activities will include the implementation of best management practices, construction of bioretention cells, the purchase of conservation easements in the Eucha/Spavinaw watershed and riparian protection and streambank stabilization in priority watersheds. Unlike pollution from industrial and sewage treatment plants, nonpoint source pollution comes from many different sources. Nonpoint source pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and man-made pollutants, depositing them into lakes, rivers, wetlands, coastal waters and groundwater. Nonpoint source pollution ...
Numerical modelling can be a useful tool to assess a receiving water bodys quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In the present study, a hydrodynamic river water quality model is presented. The model consists of a quantity and a quality sub-model. The quantity sub-model is based on the Saint Venant equations. The solution of the Saint Venant equations is obtained by means of an explicit scheme based on space-time conservation. The method considers the unification of space and time and the enforcement of flux conservation in both space and time. On the other hand, the quality sub-model is based on the advection dispersion equation. Particularly, the principle of upstream weighting applied to finite difference methods is employed. This method enable us to reduce the ...

Bacteria, viruses, and other microorganisms.. Ground-water infiltration from agricultural lands to which nutrients have been applied may transport the following pollutants: soluble nutrients and chemicals, such as nitrogen, phosphorus, metals, and many other major and minor nutrients, and salts.. Surface water and ground-water pollutants from organic matter and crop residue decomposition and from legumes growing on agricultural land may include nitrogen, phosphorus, and other essential nutrients found in the residue of growing crops.. All plants require nutrients for growth. In aquatic environments, nutrient availability usually limits plant growth. Nitrogen and phosphorus generally are present at background or natural levels below 0.3 and 0.05 mg/L, respectively. When these nutrients are introduced into a stream, lake, or estuary at higher rates, aquatic plant productivity may increase dramatically. This process, referred to as cultural eutrophication, may adversely affect the suitability of ...
The present invention relates to a non-set retarding lignosulfonate dispersing agent useful for making an aqueous calcined gypsum slurry, said dispersing agent produced by contacting an aqueous solution of a lignosulfonate with a salt of a multivalent metal selected from the group consisting of iron (II), iron (III), manganese (II) and cobalt (II) to form an aqueous solution of a multivalent metal salt and lignosulfonate having an acidic pH, and thereafter neutralizing said aqueous solution of said multivalent metal salt and lignosulfonate at an elevated temperature with an alkaline material.

Water quality is a major environmental issue. Pollution from nonpoint sources is the single largest remaining source of water quality impairments in the United States. Agriculture is a major source of several nonpoint-source pollutants, including nutrients, sediment, pesticides, and salts. Agricultural nonpoint pollution reduction policies can be designed to induce producers to change their production practices in ways that improve the environmental and related economic consequences of production. The information necessary to design economically efficient pollution control policies is almost always lacking. Instead, policies can be designed to achieve specific environmental or other similarly related goals at least cost, given transaction costs and any other political, legal, or informational constraints that may exist. This report outlines the economic characteristics of five instruments that can be used to reduce agricultural nonpoint source pollution (economic incentives, standards, education,
In the past few decades, the results of epidemiological studies have shown that there is a significant relationship between human health and air pollution. The aim of this study was to quantify the health effects, the estimated number of cases of death, cardiovascular and respiratory deaths attributed to NO2 and SO2 pollutants in Bukan city by Air Quality software. Bukan city has a population of 224,628 persons and an area of 2541.306 square kilometer. Raw data of SO2 and NO2 concentrations were received from the Department of Environment of Bukan city. To analyze the data, the Excel and Air quality 2.2.3 softwares were employed. The annual average of SO2 concentration was 85.61 μg m-3 which is higher than the WHO AQGs and Iranian National Standard. Air Quality model predicted that with every 10 μg m-3 increase in gaseous SO2, total, respiratory and cardiovascular mortality related to SO2 was 36.2, 7.8 and 29.9 deaths, respectively. The average concentration of NO2 was almost constant throughout the

Fish habitat in lakes is strongly constrained by water temperature (T) and available dissolved oxygen (DO) that are changed under climate warming. A one dimensional, dynamic water quality model MINLAKE2012 was used for T and DO simulation over 48 years. A fish habitat model FishHabitat2013 using simulated T and DO profiles as input was developed to determine lethal conditions of cisco Corgenous artedi in Minnesota lakes. Twenty-three lakes that had observations of cisco mortality or survival in the unusually warm summer of 2006 were used for model validation. The cisco habitat model used a lethal temperature of 22.1 °C and DO survival limit of 3 mg/L determined through model validation and sensitivity analysis. Cisco lethal conditions in 12 shallow, 16 medium-depth, and 30 deep virtual lakes were then simulated. Isopleths of total number of years with cisco kill and average cisco kill days for the years with kills under past (1961-2008) and future climate were generated to understand/extrapolate

Rationale: A recent UN assessment of the MDGs noted that sufficient progress is being made towards the goal of "reducing in half the number of people without access to drinking water". Despite this progress, nearly a billion people would still lack access to any source of safe drinking water. Water supply and water quality problems continue to be two of the topmost development needs in Member States due to multiple sources of stress on resources, including greater needs for food production for an increasing population, irrigated agriculture, energy production, and climate variability and change. A key to increasing the availability and sustainability of water is to develop a comprehensive, scientific assessment of surface and groundwater resources.. Progress on another MDG, which calls for stopping the over-exploitation of water resources, also cannot be easily achieved and documented without the availability of credible resource assessments. In spite of the fact that a need for water resources ...

With the exception of the coastal plains and the Niger-Benue valley, Nigeria consists mostly of high plains and plateaus. Directly to the east of the Lower Niger Valley are the Udi and Igala Plateaus and the Akwa-Orlu Uplands. The general elevation of these plateaus is about 304 meters (1,000 feet), with escarpments rising considerably higher. Between the low western coastal plains and the Niger-Benue River valley lie the Western High Plains, or Plateau of Yorubaland, part of the belt of high plains that extends through West Africa. Plateau surfaces here vary in elevation from about 228 meters to 372 meters (750 feet to 1,200 feet), with some dome-shaped hills attaining a height of 609 meters (2,000 feet). North of the Niger-Benue valley lies a broad plateau, the Northern High Plains or the High Plains of Hausaland. The central section of the plateau extends for about 482 kilometers (300 miles) from east to west, with stepped plains ranging from about 183 meters (600 feet) at the outer edge to ...
A method of manufacturing a lignosulfonate-phenol-formaldehyde resin includes heating a mixture of phenol, formaldehyde, lignosulfonate and alkali at a temperature of 60 C. to 100 C. and a pH of 8-13. The lignosulfonate comprises about 5 to about 80 percent of the total weight of phenol, formaldehyde and lignosulfonate and the lignosulfonate is mixed with said phenol and formaldehyde before substantial reaction between said phenol and said formaldehyde. Also disclosed are fibrous articles manufactured using this resin as a binder.
Results show that SOA mass concentrations predicted by the UCD/CIT-SOM model are very similar to those predicted by a two-product model when both models use parameters that are derived from the same chamber data. Since the two-product model does not explicitly resolve multi-generational oxidation reactions, this finding suggests that the chamber data used to parameterize the models captures the majority of the SOA mass formation from multi-generational oxidation under the conditions tested. Consequently, the use of low and high NOx yields perturbs SOA concentrations by a factor of two and are probably a much stronger determinant in 3-D models than multi-generational oxidation. While total predicted SOA mass is similar for the SOM and two-product models, the SOM model predicts increased SOA contributions from anthropogenic (alkane, aromatic) and sesquiterpenes and decreased SOA contributions from isoprene and monoterpene relative to the two-product model calculations. The SOA predicted by SOM has ...
