The Safe Drinking Water Act includes provisions for state wellhead protection programs which address wellhead protection areas. In Utah, these areas are called drinking water source protection (DWSP) zones. Zones Two and Three are delineated according to analytical or numerical techniques, which are based on hydrogeological and time-of-travel data, as well as recharge information, accumulated through the use of hydrogeologic and hydrochemical techniques. The primary conclusions of this research are: 1) A fence diagram and site hydrostratigraphic diagram show that the hydrogeology is more complex than previously has been thought . The principal aquifer at the target well site comprises a sequence of mostly coarse-grained units interspersed with thinner fine-grained units. The supposedly unconfined shallow aquifer is confined in most parts of the valley, including the target well site. 2) The recovery rate of water levels in the monitor wells in response to pumping of the target well indicates that horizontal groundwater flow velocities are low at the target well site. X 3) Interpretation of major ions relative to the depth of uppermost open interval of the various sample wells indicates that the deeper of the three major water-bearing zones (below 300 to 350 feet [91 to 107 meters]) is not well connected to the upper two zones. 4) The chemical evolution of the water along the westernmost of three discrete flowpaths indicates a change from young calcium bicarbonate water to moderately mature sodium-sulfate water. 5) Sample waters recharged from the northern Wasatch Mountains have higher total-dissolved-solids (TDS) contents then sample waters recharged from the southern Wasatch Mountains . 6) The discrepancy between many of the δ18O, δD, and tritium data as to the probable recharge area(s) indicate that the sample wells must be evaluated on an individual basis regarding the source of recharge water. 7) The tritium data demonstrate that those wells located farthest out into the valley or having the deepest uppermost open interval furnish the lowest tritium values. 8) Based on the 14C dating technique , the groundwater at the target well site appears to be between 1300 and 5300 years old. 9) There is little risk of contamination at the target well site, in terns of the 15-year time-of-travel DWSP zone (Zone 3).

From the Pioneer Company of 1847 to the completion of the transcontinental railroad in 1869, approximately 60,000 Mormon pioneers made the journey from Winter Quarters to the Salt Lake Valley. Although some years have received more attention, every footprint placed on the prairie is part of the epic pioneer story. This thesis examines the major challenges and characteristics of the 1848 Mormon pioneers crossing of the plains. The sacrifices and contributions of the 1848 pioneers are as significant to the legacy of the Mormon westward migration as any other year. In order to explore, develop, and explain the thesis statement, this work includes five chapters. Chapter I: Introduction provides the historical setting of the 1848 Mormon pioneers. Chapter II: The L.D.S migration of 1848 in historical context. Chapter III: The general characteristics of the 1848 Mormon migration. Chapter IV: Relief efforts. Chapter V: Conclusion. The primary evidence for this thesis comes from journals of the 1848 Mormon pioneers. This research has discovered that the 1848 pioneers had the largest company in Mormon pioneer history. It is also the only year that each member of the First Presidency led a pioneer company across the plains. The companies' immense size coupled with insufficient provisions and an unusually dry spring required sacrifice and cooperation. Topics researched include: route and distances traveled, role of women, expressions of devotion, livestock issues, Indian relations, sickness, injury, and death. The 1848 pioneers received significant relief from 1847 migrants, who returned to the trail to assist.

Recognizing a need to develop religious instructional material for mentally retarded seminary students of the L.D.S. Church, this study was designed to validate an instructional model set up to teach the concept of faith.Thirty-four mentally retarded seminary students were randomly assigned to six control groups and six experimental groups. Each group was given a sixteen question pre-test. Then, the next day each experimental group was given instructional treatment and the post-test, while the control groups only received the post-test. The Study was geared for a two hour period of time. Results obtained from the analysis of covariance showed a significant difference beyond the .01 level on post-test results of the experimental groups when compared to the post-test results of the control groups. Thus, the null hypothesis was rejected.

Research on health effects of particulate matter (PM) has been a very active area in the last two decades. One plausible mechanism by which exposure to PM affects human health includes modification of autonomic endothelium function. Decreased endothelium activity causes heightened risks of cardiovascular disease. A human exposure chamber designed to conduct experiments to quantify diminished function of endothelium from short term exposure to PM is described. The chamber consists of two stages for containment and pre-treatment of PM and exposure of human subjects. Concentrations of CO, CO2, NO, NO2, O3, and PM2.5, are monitored and controlled in the exposure room. The PM used in the human exposure experiments was characterized chemically and morphologically. During January and February of 2009, chemical analysis of PM2.5 was done during inversion periods in Salt Lake City, UT. An Ambient Ion Monitor (AIM) was deployed to measure the concentrations of anions in both particulate and gas phases. The chemical data provided by AIM was complemented by measurements by the Department of Air Quality that included PM10, PM2.5, O3, NO, NO2, NH3 and CO. The goal of the study was to determine whether ammonia or nitric acid is the limiting reagent in formation of PM during inversions. Nitric acid is the limiting reagent. Concentrations of ammonia are an order of magnitude higher than nitric acid.

The purpose of the study was to determine what degree of understanding third year graduates of the SLVN Seminary District had of the nature and mission of Christ.The study was composed of a random sample of 200 third year seminary graduates. Each participant answered a questionnaire designed to test his understanding of the nature and mission of Christ. The responses were tabulated and presented in written and illustrative form.The students met the minimum established standard of 75% in four of the five concepts which they were questioned concerning the nature of Christ. The students met the minimum established standard in five of the eight concepts testing their understanding of the mission of Christ.Overall comprehension of both the nature and mission of Christ were considered adequate as the students averaged 80% correct responses to all questions.

This thesis found that the three communities of Midvale, Murray, and Sandy were the center of the smelting industry in the Salt Lake Valley. These communities became the center of smelting because of their central location, the readily available water supply, and the availability of an inexpensive, efficient transportation system to ship the bullion. The smelters were surrounded by two major mountain ranges which provided a ready supply of good lead, silver, and copper ore.The development of the smelting industry followed three separate phases or periods. The first phase was one of experimentation or period of discovery, in which the smelters operated without the technological skill necessary to be financially successful. The second phase was highlighted by the emergence of skilled German mining engineers who enabled the smelters to be financially successful. Phase three was ushered in during the late nineteenth century by the industrialists who consolidated the smaller smelters and built larger, more efficient plants.
