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 ...

This paper focuses on a Hybrid Process that uses feed salinity dilution and osmotic power recovery from Pressure Retarded Osmosis (PRO) to achieve higher overall water recovery. This reduces the energy consumption and capital costs of conventional seawater desalination and water reuse processes. The Hybrid Process increases the amount of water recovered from the current 66.7% for conventional seawater desalination and water reuse processes to a potential 80% through the use of reclaimed water brine as an impaired water source. A reduction of up to 23% in energy consumption is projected via the Hybrid Process. The attractiveness is amplified by potential capital cost savings ranging from 8.7%-20% compared to conventional designs of seawater desalination plants. A decision matrix in the form of a customizable scorecard is introduced for evaluating a Hybrid Process based on the importance of land space, capital costs, energy consumption and membrane fouling. This study provides a new perspective, ...

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,

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

Q: When it comes to functional wear, what special features are consumers looking into and how does sustainability play a role in this? Birgit: When we talk about functional wear, the scope ranges from athleisure to outdoor to high-performance sportswear for apparel and shoes. Consumers are looking for different features in different areas. If we want to put them under one umbrella, respect for nature and environmental sustainability is important, People love to do sports in nature, and they also now have higher awareness to combat climate change and lower CO2 emissions. Secondly, it comes as a feel good feature because consumers who purchase sportswear want to feel good in their bodies. Since skin is the largest organ in the body, they want to wear clothes that feel comfortable and that allow their skin to breathe through their clothes. These key features are now especially important when it comes to COVID-19, as we see more people working from home and working out from home. More consumers ...

In recent years, the rise in popular awareness over climate change and the consequent attention governments have had over the matter has brought to ever-harder goals of environmental sustainability in all sectors of industry. Carbon capture and utilization schemes are one of the many routes that have been proposed to increase the environmental sustainability of the transport and chemical industries, which are two of the biggest carbon emitters on the planet. This strategy aims at closing the cycle of fossil fuel burning by using renewable energy to transform water and carbon dioxide back into fuels and chemicals. In this work, we present a computational study of the electronic structure and catalytic performances of two classes of materials, carbon nitrides and transition metal carbides. Carbon nitrides are semiconductors used for photocatalytic water splitting, a nature-mimicking process which aims at the direct conversion of H2O into H2 and O2 using solar irradiation and band gap tuned ...

Urban water reuse is one of the most rapidly growing water reuse applications worldwide and one of the major elements of the sustainable management of urban water cycle. Because of the high probability of direct contact between consumers and recycled water, many technical and regulatory challenges have to be overcome in order to minimize health risks at affordable cost. This paper illustrates the keys to success of one of the first urban water reuse projects in the island Bora Bora, French Polynesia. Special emphasis is given on the reliability of operation of the membrane tertiary treatment, economic viability in terms of pricing of recycled water and operating costs, as well as on the benefits of water reuse for the sustainable development of tourist areas.

By: Dr. Phil Rolchigo. Around the country, more and more cities are faced with a diminishing water supply due in part to uncontrollable circumstances such as extended drought and changing weather patterns. Conservation alone is not enough to reverse the trend. With more than 32 billion gallons of municipal wastewater produced every day in the United States, water reuse, the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation, has the potential to increase the nations total water supply, while also providing an additional revenue stream for municipalities.. As a result, we are seeing three emerging trends in the area of resource recovery from wastewater: Municipal Water Reuse Solutions. Many municipalities are exploring opportunities to expand capability and increase revenue through both direct and indirect water reuse. And, while the technology exists to return wastewater to potable drinking water standards, a more ...

This work is about finding an appropriate modelling complexity for a mass-balance model for phosphorus in Lake Vänern, Sweden. A statistical analysis of 30 years of water quality data shows that epilimnion and hypolimnion have different water quality and should be treated separately in a model. Further vertical division is not motivated. Horizontally, the lake should be divided into the two main basins Värmlandssjön and Dalbosjön. Shallow near shore ares, bays and areas close to point sources have to be considered as specific sub-basins if they are to be modelled correctly.. These results leads to the use of a model based on ordinary differential equations. The model applied is named LEEDS (Lake Eutrophication Effect Dose Sensitivity) and considers phosphorus and suspended particles. Several modifications were made for the application of the model to Lake Vänern. The two major ones are a revision of the equations governing the outflow of phosphorus and suspended particle through the outflow ...

The dynamic analysis process was started after failure in some embankments during an earthquake. In this context, maximum displacement was reported at the crest based on interaction between structure and reservoir. This paper investigates the dynamic behavior of short embankment on soft soil. For this purpose, numerical analysis was carried out using ANSYS13 program based on finite-element method. Simulated models were vibrated by strong earthquake, so the peak ground acceleration (PGA) and duration were 0.65 g and 5.02 seconds, respectively. The comparison results were discussed in key points of plane strain analysis based on modulus ratio between saturated embankment and foundation. As concluded, the modulus ratio between 0.53 and 0.66 led to having a minimum value of horizontal displacement, relative displacement in vertical direction, and shear stress. Consequently, the shear stress was increased while the modulus ratio was decreased. Finally, to avoid more rigidity in the embankment on the

In spite of widespread insecticide resistance in vector mosquitoes throughout Africa, there is limited evidence that long lasting insecticidal bed nets (LLINs) are failing to protect against malaria. Here, we showed that LLIN contact in the course of host-seeking resulted in higher mortality of resistant Anopheles spp. mosquitoes than predicted from standard laboratory exposures with the same net. We also found that sub-lethal contact with an LLIN caused a reduction in blood feeding and subsequent host-seeking success in multiple lines of resistant mosquitoes from the lab and the field. Using a transmission model, we showed that when these LLIN-related lethal and sub-lethal effects were accrued over mosquito lifetimes, they greatly reduced the impact of resistance on malaria transmission potential under conditions of high net coverage. If coverage falls, the epidemiological impact is far more pronounced. Similarly, if the intensity of resistance intensifies, the loss of malaria control increases ...

The research in the area has largely ignored the moderating effects of the customer trait, self-efficacy, on the electronic service quality model. This study examines the degree to which electronic service quality dimensions influence overall service quality, which in turn affects customer satisfaction and loyalty. On the basis of self-efficacy theory, this paper argues that outcome quality is the most important predictor of overall quality, whereas environment quality is the least important predictor of overall quality, particularly when self-efficacy is high. Additionally, the paper demonstrates that self-efficacy strengthens the link between customer satisfaction and both repurchase intention and word of mouth. Data collected from 162 participants provide support for most of these hypotheses.. ...

There are a number of desalination technologies, and if it is not done properly, the seawater intake process can unnecessarily kill marine life. Desalination also produces a highly concentrated brine discharge that degrades water quality and marine life habitat if not properly diluted. …. There are numerous ocean desalination facilities being proposed in California, all in various stages of planning or permitting. Many of the proposed facilities have not been designed to minimize degradation to marine habitats and water quality, nor are the proposals being thoroughly evaluated by any government agency for their cumulative impacts statewide. The California State Water Resources Control Board is currently in the process of collecting scientific data on the adverse impacts of ocean desalination, and how best to minimize those impacts. But some proposals are moving forward without having adopted the recommendations of the science community - Poseidons project proposal is the worst offender. ...

How Seawater Desalination Works ? : Desalination is a process that removes minerals from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture.

The competition or rivalry for the use of water resources among economic sectors of the Pacific Northwest and among geographical regions of the western United States has intensified in recent years. This rivalry and the long run prospects for water shortages have increased the demand for research concerning the productivity of this resource in alternative uses. This demand exists because the distribution and use of water resources require investment which typically comes from both public and private sources. Private and public planning groups seek answers to questions regarding future water resource development alternatives. Agriculture has historically been a major user of water in the Pacific Northwest. A substantial portion of total investment in water resource development has also been, in agriculture. As a result water use planners and decision making bodies are necessarily interested in water use in agriculture. The success of water resource planning requires answers to questions regarding ...

Channel Islands National Marine Sanctuary provides habitat for a wealth of biological diversity, outstanding recreational opportunities and spectacular scenery. Every organism that resides within or moves through the sanctuary depends upon clean water, as do all our commercial and recreational uses.. Poor water quality can cause illness or disease, impair condition and reproductive capacity, and decrease productivity in marine organisms. It can also endanger human users of the sanctuary. Sources of water quality impairment in the sanctuary are land-based discharges from the mainland and the islands (e.g., runoff can include sediment, bacteria, and agricultural-based chemicals such as pesticides and herbicides), vessel discharges from recreational, commercial, and industrial vessels (e.g., sewage, bacteria, and marine debris), and discharges associated with oil production (Engle 2006). Nonpoint source pollution from the mainland may reach the eastern portion of the sanctuary (Anacapa and Santa ...

Due to the increasing demand for clean and potable water stemming from population growth and exacerbated by the scarcity of fresh water resources, more attention has been drawn to innovative methods for water desalination. Capacitive deionization (CDI) is a low maintenance and energy efficient technique for desalinating brackish water, which employs an electrical field to adsorb ions into a high-porous media. After the saturation of the porous electrodes, their adsorption capacity can be restored through a regeneration process. Herein, based on a physical model previously developed, we conjecture that for a given amount of time and volume of water, multiple desalination cycles in a high flow rate regime will outperform desalinating in a single cycle at a low flow rate. Moreover, splitting a CDI unit into two subunits, with the same total length, will lead to higher desalination. Based on these premises, we introduce a new approach aimed at enhancing the overall performance of CDI. An array of ...

This document provides guidance for designing water quality monitoring projects and selecting monitoring parameters. Although the focus is on forest management and streams in the Pacific Northwest and Alaska, a broader perspective is taken, and much of the information is more widely applicable. Part I reviews the regulatory mechanisms for nonpoint source pollution and defines seven types of monitoring. A step-by-step process for developing monitoring projects is presented. Because monitoring is a sampling procedure, study design and statistical analysis are explicitly addressed. Part II is a technical review of the parameters, which are grouped into six categories: physical and chemical constituents, flow, sediment, channel characteristics, riparian, and aquatic organisms ...

High costs, in money and energy, limit the usefulness of desalination as a way to provide drinkable water in disaster areas. However, a new method could lead to portable desalination devices simple enough to run off solar power or a battery, but powerful enough to supply a family, or even a small village, with clean water. Additionally, the new desalination device also cleanses water of biological contaminants.

With water fast becoming a hot commodity, especially in drought-prone regions with burgeoning populations, an obvious solution is to take the salt out of seawater. Desalination technology has been around for thousands of years, after all. Even Aristotle worked on the problem. Tantalizing as desalinated water might sound, the energy costs have made it rather unpalatable. Until recently, seawater desalination was a very expensive water source solution, said Gary Crisp, an engineer for the Water Corporation of Western Australia. Drinking seawater straight is a bad idea because your body must expel the salt by urinating more water than it actually gains. Seawater contains roughly 130 grams of salt per gallon. Desalination can reduce salt levels to below 2 grams per gallon, which is the limit for safe human consumption. Currently, between 10 and 13 billion gallons of water are desalinated worldwide per day. Thats only about 0.2 percent of global water consumption, but the number is increasing. ...

AU - Darwish, N. A.. AU - Ali, N.. PY - 2007/2/5. Y1 - 2007/2/5. N2 - Nanofiltration (NF) membranes have been successfully used in various applications in water and wastewater treatment as well as other industries. In desalination plants, NF membranes were found to be suitable for pre-treatment application prior to the desalination process. In general NF membranes can be characterized in terms ofthe effective pore radius (rp), effective charge density (Xd) and permeability (Pm). NF membranes available in the market show a wide range of these properties and thus this variation affects the membrane performance significantly. Through a predictive model such as the Donnan-Steric-Pore-Dielectric-Exclusion (DSPM-DE) model, the performance of NF membranes can be predicted in terms of the solute rejections, fluxes ...

Reusing wastewater can assist in solving water shortage problems, reduce the amount of wastewater discharged to surface water bodies and, by extension, alleviate its adverse effects on humans and the environment. Organics found in wastewater can be removed through biological treatment, however, if secondary effluent is to be reused for potable or some nonpotable applications, some form of advanced treatment is required. Membranes are often used to further treat these effluents for water reuse as they require only a small footprint and can provide a high quality treated water. They are also robust as is relates to dealing with feed waters of varying composition. However, due to the accumulation of rejected contaminants and certain natural organic matter (NOM) constituents on membrane surfaces and within pores, fouling can be an important shortcoming of this technology. Small improvements in the reduction of foulants can translate into substantial improvements in production quantity and cost ...

Reservoirs on rivers can disrupt organic carbon (OC) transport and transformation, but less is known how river reaches directly below dams contribute to OC processing. We compared how reservoirs and their associated tailwaters affected OC quantity and quality by calculating particulate OC (POC) and dissolved OC (DOC) fluxes, and measuring composition and bioavailability of DOC. We sampled the Yampa River near Maybell, Colorado, USA, and the Green River above and below Fontenelle and Flaming Gorge reservoirs as well as their respective tailwaters from early snowmelt to base flow hydrological conditions. In unregulated reaches (Yampa River, Green River above Fontenelle reservoir), DOC and POC concentrations increased with snowmelt discharge. POC and DOC concentrations also increased with stream discharge below Fontenelle reservoir, but there was no relationship between DOC and stream flow below Flaming Gorge reservoir. The annual load of POC was 3-fold lower below Fontenelle Reservoir and nearly ...
