Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers

Michael Johnson

Artificially recharging the Las Vegas Valley (Valley) ground-water system with treated Colorado River water is one water resource management option employed by the Las Vegas Valley Water District (District) to help meet future long-term and short-term peak water demands. The District began operation of an artificial ground-water recharge program in 1988 in order to bank water for future use and to slow declining water levels. Artificial recharge occurs in the winter months, typically from October to May, when there is excess capacity in the Southern Nevada Water System (SNWS), currently a 400 Million Gallon per Day (MGD) treatment and transmission ...

The provision of safely managed sanitation in informal settlements is a challenge, especially in schools that require durable, clean, sex-segregated facilities for a large number of children. In informal settlements in Nairobi, school sanitation facilities demand considerable capital costs, yet are prone to breakage and often unhygienic. The private sector may be able to provide quality facilities and services to schools at lower costs as an alternative to the sanitation that is traditionally provided by the government. We conducted a randomized trial comparing private sector service delivery (PSSD) of urine-diverting dry latrines with routine waste collection and maintenance and government ...

Cover crops are an important component of the Iowa Nutrient Reduction Strategy, which calls for a high level of adoption to reach the goals of reducing nitrate-nitrogen and phosphorus. Iowa landowners and farmers are increasingly seeing the value of single species cover crops and incorporating them into their cropping systems. However, in Iowa and the Upper Midwest, there is limited research on using cover crop mixtures.

Rickettsia philipii (type strain “Rickettsia 364D”), the etiologic agent of Pacific Coast tick fever (PCTF), is transmitted to people by the Pacific Coast tick, Dermacentor occidentalis. Following the first confirmed human case of PCTF in 2008, 13 additional human cases have been reported in California, more than half of which were pediatric cases. The most common features of PCTF are the presence of at least one necrotic lesion known as an eschar (100%), fever (85%), and headache (79%); four case-patients required hospitalization and four had multiple eschars. Findings presented here implicate the nymphal or larval stages of D. occidentalis as ...

Aerosol analysis from the interdependent data assessment show comparable aerosols characteristics over the eight year period with higher aerosols mean optical depths over enhanced dust load region, (46–50°E, 25–29°N), during March–May ...


In Continuity With The Past: Indigenous Environmentalism And Indian Christian Visions Of Flora, James Ponniah 2016 Department of Christian Studies, University of Madras, Chennai, India

In Continuity With The Past: Indigenous Environmentalism And Indian Christian Visions Of Flora, James Ponniah

Journal of Global Catholicism

This article considers whether Indian Christianity can be said to have a distinctive ecological vision. The first two parts of the article examine Christian environmentalism in two native forms of Indian Christianity: Tamil Christianity and Tribal Christianity. Continuing with the theme of conformity to the local culture—though of the elite—the third part of the article investigates how Christian Ashrams function as dynamic centers for ecological praxis. The last part of the article considers how contemporary Indian Christian communities can respond to the ecological challenges confronting them.

The Pinchot Wire: Private Cash, Public Lands - Why The Katahdin Woods And Waters National Monument Matters, Char Miller

Pomona Faculty Publications and Research

Here’s how President Obama celebrated the National Park Service’s 100th birthday: with the stroke of his pen, he established the Katahdin Woods and Waters National Monument in Maine, one of the most innovative initiatives in U.S. environmental history. That’s because the 87,500-acre park, which encompasses some of the Pine Tree State’s most remarkable forests and waterways, is a gift of the Quimby family and comes with a $40 million endowment, a private-public partnership without parallel.

Influence Of Resource Availability On Juniperus Virginiana Expansion In A Forest–Prairie Ecotone, A. C. Ganguli, D. M. Engle, P. M. Mayer, L. F. Salo

U.S. Environmental Protection Agency Papers

Woody plant expansion into grasslands and savannas is a global concern. Rapid expansion of Juniperus virginiana, a tree native to North America, has profound ecological consequences. We used transplanted J. virginiana seedlings to investigate the role of resource availability on J. virginiana expansion following the removal of fire, the factor historically limiting range expansion of this fire-intolerant species. We evaluated J. virginiana seedling survival and seedling growth, two important phases in woody plant expansion, relative to two below ground resource factors, plant-available soil water (soil clay content, an index of plant-available soil water) and plant-available nitrogen (PAN), and an above ...

Abstract

Refrigerants have been one of the causes of ozone depletion and the buildup of greenhouse gases in past decades. When the international agreements the Montreal Protocol, which has the goal of eliminating ozone depleting compounds, and the Kyoto protocol which has the goal of eliminating greenhouse gas emissions, where implemented they paved the way to replace past and current refrigerants with alternate compounds that are less detrimental to the atmosphere. New compounds that where green-lit by the EPA for use as refrigerants in 2011 where HFO-1234ze and HFO-1234yf, both of these compounds have a very low Global ...


Impact Of Dairy Cows On Air Quality And Particulate Matter In The San Joaquin Valley, Daniel A. Bauerlein 2016 American Public University System

Impact Of Dairy Cows On Air Quality And Particulate Matter In The San Joaquin Valley, Daniel A. Bauerlein

Master's Capstone Theses

The San Joaquin Valley (SJV) is the largest producer of dairy in California and the United States. The SJV consists of eight counties which held approximately 1.5 million dairy cows in 2014. The region continually fails to meet air quality standards for particulate matter under 2.5 micrometers (PM2.5) set by the Environmental Protection Agency under the Clean Air Act. Previous studies have shown that the presence of dairy cows is a contributing factor increasing the amount of PM2.5in the air. This study investigates the relationship between the number of dairy cows, dairies, and cows per dairy ...


The Role Of Organic Matter In The Fate And Transport Of Antibiotic Resistance, Metals, And Nutrients In The Karst Of Northwest Arkansas, Victor Lee Roland II 2016 University of Arkansas, Fayetteville

The Role Of Organic Matter In The Fate And Transport Of Antibiotic Resistance, Metals, And Nutrients In The Karst Of Northwest Arkansas, Victor Lee Roland Ii

Theses and Dissertations

Organic matter (OM) in the environment acts as a nutrient, but may also act as a transport vector for harmful chemical compounds and bacteria. Acetate is a labile form of OM produced during fermentation in anaerobic lagoons used to store animal fecal-waste from concentrated animal feeding operations (CAFOs). Dry and liquid fertilizers from CAFOs pose a threat to groundwater by introducing excessive amounts of nutrients (e.g. OM, nitrate and ammonia), metals, and antibiotic compounds. In the epikarst of Northern Arkansas in the Buffalo River watershed additional input of labile dissolved organic carbon (DOC) from liquid CAFO waste-fertilizers was hypothesized ...

Historical residential electricity data and natural gas consumption data were collected for, respectively, 1,200 and 178 residences in a small town in the USA. These data were merged with local building and weather databases, and energy consumption models were developed for each residence, revealing substantial variation in heating and cooling intensity. After estimating approximate physical building characteristics, energy profiles for each residence were calculated, and savings from adoption of the most cost-effective energy-efficiency measures for each residence were estimated. Effectively, we wish to leverage commonly available data sets to infer characteristics of building envelopes and equipment, without the need ...

Nitrogen Management Under Uncertainty: An Investigation Of Farmers’ Decision Processes, Keri L. Jacobs, Quinn Weninger

Quinn Weninger

Des Moines Water Works has recently threatened a lawsuit against three upstream Iowa counties they claim are responsible for excessive nitrate loading in the Raccoon and Des Moines rivers. Excess nitrate loads, which must be reduced before water is safe to drink, is reported to have cost Des Moines taxpayers upwards of $1 million in 2013. The cost of nitrate removal, which could include investment in new treatment capacity, will continue, and may grow, unless steps are taken to reduce nitrate runoff from agriculture. While such water treatment is costly, yield losses may be more costly if rates are capped ...
