Geochemistry, Alluvial Facies Distribution, Hydrogeology, and Groundwater Quality of the Dallas-Monmouth Area, Oregon

Caldwell, Rodney R 23 April 1993 (has links)
The Dallas-Monmouth area, located in the west-central Willamette Valley, Oregon, consists of Tertiary marine and volcanic bedrock units which are locally overlain by alluvium. The occurrence of groundwater with high salinities has forced many rural residents to use public water supplies. Lithologic descriptions from driller's logs, geochemical (INAA), and x-ray diffraction analyses were used to determine alluvial facies distribution, geochemical and clay mineral distinctions among the units, and possible sediment sources. Driller's log, chemical and isotopic analysis, and specific conductance information from wells and springs were used to study the hydrogeologic characteristics of the aquifers and determine the distribution, characteristics, controlling factors, and origin of the problem groundwaters. Three lithologic units are recognized within the alluvium on the basis of grain-size: 1) a lower fine-grained unit; 2) a coarse-grained unit; and 3) an upper fine-grained unit. As indicated by geochemical data, probable sediment sources include: 1) Cascade Range for the recent river alluvium; 2) Columbia Basin plutonic or metamorphic rocks for the upper fine-grained older alluvium; and 3) Siletz River Volcanics from the west for the coarse-grained sediment of the older alluvium. The Spencer Formation (Ts) is geochemically distinct from the Yamhill Formation (Ty) and the undifferentiated Eocene-Oligocene sedimentary rock (Toe) with higher Th, Rb, K, and La and lower Fe, Sc, and Co concentrations. The clay mineralogy of the Ty is predominantly smectite (86%) while the Ts contains a more varied clay suite (kaolinite, 39%; smectite, 53%; and illite 8%). The Ty and Toe are geochemically similar, but are separated stratigraphically by the Ts. The Siletz River Volcanics is distinct from the marine sedimentary units with higher Fe, Na, Co, Cr and Sc concentrations. The Ty and Toe are geochemically similar to volcanic-arc derived sediments while the Ts is similar to more chemically-evolved continental crust material. Wells that encounter groundwater with high salinities (TDS>300 mg/1): 1) obtain water from the marine sedimentary bedrock units or the older alluvium; 2) are completed within zones of relatively low permeability (specific capacities ~5 gpm/ft); and 3) are located in relatively low-lying topographic settings. The poor quality waters occurring under these conditions may be due to the occurrence of mineralized, regional flow system waters. Aquifers of low permeability are less likely to be flushed with recent meteoric water, whereas upland areas and areas with little low permeability overburden are likely zones of active recharge and flushing with fresh, meteoric water. The most saline waters sampled have average isotopic values (6D = -6.7 ° / 00 and 60 = -1.7 ° / 00 ) very near to SMOW, while the other waters sampled have isotopic signatures indicative of a local meteoric origin. The Br/Cl ratios of most (10 of 14) of the waters sampled are within 20% of seawater. A marine connate origin is proposed for these waters with varying amounts of dilution with meteoric waters and water-rock interaction. The problem waters can be classified into three chemically distinct groups: 1) CaC12 waters, with Ca as the dominant cation; 2) NaCl waters with Na as the dominant cation; and 3) Na-Ca-Cl waters with nearly equal Na and Ca concentrations. The NaCl and CaC12 waters may have similar marine connate origins, but have undergone different evolutionary histories. The Na-Ca-Cl waters may represent a mixing of the NaCl and CaC12 waters.

A Study Of The Grant Writing Policies And Practices Of Municipalities In Polk County Florida Having A Population Less Than 25,000

Carter, Michael Scott 01 January 2011 (has links)
The purpose of this study is to identify the grant writing policies and practices of the fifteen municipalities in Polk County, Florida having a population less than 25,000, compare these findings qualitatively, and to present the data in a form usable by any city in Polk County so each city can make any needed adjustments to their grant writing strategy that will increase their success of grant funding. This study is needed now because smaller cities are continuing to feel the effects of the recession, a slumping housing market, and a reduction of real estate property values which means lower tax revenue. City managers and staff need to sharpen their grant writing skills to maximize the success of their grant applications. Both quantitative and qualitative research methodology were used in this study. The quantitative research data was gathered with the aid of a survey sent to each city manager of the selected cities. The qualitative research data consists of follow-up interviews with the fifteen city managers. Fourteen of the fifteen cities responded and all returned surveys were 100% complete. The results of the survey include respondent demographics, a lengthy discussion of each city‟s attitudes and history with grant application and administration, and the training level of staff involved in grant writing. The chapter goes on to analyze and discuss the policy of local elected officials regarding grants and concludes on the topic of challenges facing Polk County municipalities and possible solutions that may increase their grant writing success. The final chapter brings the study to a conclusion with a summary and a review of the findings from the survey. Several recommendations are offered that, if implemented, could increase the success rate cities are currently achieving with grant applications. Several iv implications are offered of possible outcomes if no changes are made, and finally, specific areas of future research and study are discussed.

Biostratigraphy of the Type Yamhill Formation, Polk County, Oregon

Gaston, Larry R. 01 January 1974 (has links)
One hundred and seventy-four species and varieties of fossil Foraminifera are recorded from thirty-eight localities in the Siletz River Volcanics, Yamhill and Nestucca Formations exposed along Mill and Gooseneck Creeks, in the Northern Coast Range of Oregon. Marginulina holmesi is described as new. The Foraminifera indicate that this sequence was deposited during late Ulatisian and Narizian time, in marine waters at bathyal or lower neritic depths, with cool surface temperatures. The Yamhill Formation can be correlated with Moody Shale member of the Toledo Formation and the Coaledo Formation of Oregon; the McIntosh and Aldwell Formations of Washington; and the upper part of the Canoas siltstone member of the Kreyenhagen Formation and the Alhambra Formation of California. It is proposed to modify, in part, the type section of the Yamhill Formation. Approximately 2.2 miles of the section, south of the Yamhill River Fault, are excluded from the original type area. Biostratigraphic studies of foraminiferal faunae from adjacent sides of the Yamhill River Fault suggest only minor vertical displacement.

Neutron activation analysis and chemical inference for the identification of Buena Vista ceramics

Sullivan, Daniel D. 01 January 1986 (has links)
Instrumental Neutron Activation Analysis was used for this study of stonewares collected from the site of the Buena Vista/Oregon Pottery Company (1866-1890). The results show significant chemical signatures in the samples tested. Thorium/ytterbium and thorium/chromium ratios within their respective ranges of variation demonstrate a relative conformity among all samples of Buena Vista ceramics.

Which Way To The Jook Joint?: Historical Archaeology Of A Polk County, Florida Turpentine Camp

Ziel, Deborah 01 January 2013 (has links)
The extraction and distillation of pine sap for the naval stores industry reached its apex of production in the early decades of the twentieth century. Post-emancipation, the industry employed African American labor in the long leaf pine forests of the southeastern United States under a system of debt peonage that replaced the master-slave dynamic with a similar circumscriptive construct. Laborers rented company housing and were paid in scrip, a monetary system that limited their purchase of the basic goods of subsistence to the company commissary at inflated prices, resulting in an endless cycle of debt. Despite the oppressive circumstances of debt peonage labor, African Americans developed venues known as “jook joints” for the expression of agency through leisure. The jook was a structure where laborers congregated on weekends to socialize, dance, drink, gamble, and fight. The Polk County, Florida turpentine camp of Nalaka was in operation from 1919 until 1928. In 1942, the Nalaka site, and thousands of surrounding acreage, were purchased by the United States Government for use as an Air Force training range in anticipation of US involvement in World War Two. Although no structures survive, artifact scatters from the 1920s remain in situ. No known records exist to document the spatial arrangement of the structures at Nalaka. This study reconstructs the layout of the camp based upon artifact provenience, secondary iii ethnographic sources, and historical documents, to determine whether or not Nalaka supported a jook joint, and if so, where was its location.

Lake Stage Fluctuation Study in West-Central Florida Using Multiple Regression Models

Gao, Jie 10 November 2004 (has links)
Multiple linear regression models were developed to calculate lake fluctuation that occurs between 10 percent, 50 percent, and 90 percent of the time lake surface elevation is exceeded. A total of 48 lakes were selected from Hillsborough, Pasco, Highlands and Polk counties, which were identified as natural lakes through the study the Southwest Florida Water Management District (SWFWMD) conducted in 1999 and 2002 to develop the models. "Natural lake" refers to lakes that were not impacted by ground water pumping. Among these 48 lakes, 22 lakes from Hillsborough and Pasco counties sit in the coastal lowlands area. 26 lakes from Highlands and Polk counties are located in the Upland and Highlands Ridge area. In developing multiple regression models, the 48 lakes were divided into two groups, the same group of lakes that SWFWMD used to develop the Reference Lake Water Regime, the method that is used to set the minimum lake levels in the region. Further, these two groups of data were subdivided into four categories based on their physical characteristics. 22 lakes were divided into surface water flow through lakes (SWF) and surface water drainage lakes (SWD). 26 lakes used their county line as the divider to separate them into Highlands County lakes and Polk County lakes. A total of six sets of multiple regression models were developed to predict the lake stage fluctuation for lakes that have no or limited lake stage data. The Polk County date set provides the best model with R2 at 0.9. However, due to the lack of available information on lake basin characteristics, the models that were developed for Hillsborough and Pasco counties do not provide a good prediction.

Planning Growth - Preserving Character

Oliver, Nathan Daniel 01 August 2011 (has links)
Gateway communities are the towns, cities, and communities that border public lands such as national and state parks, wildlife refuges, forests, historic sites, wilderness areas, national forests, and other public lands. They offer scenic beauty and a high quality of life that attracts millions of Americans looking to escape traffic congestion, fast tempo and uniformity of cities and suburbs. Gateway communities provide food, lodging, and business for Americans on their way to public lands. They serve as portals to public lands and therefore play an important role in defining the park, forest, or wilderness experience for many visitors. Their beauty, high quality of life, and economic benefits do not come easy. Gateway communities face challenges related to managing growth and development, providing economic prosperity, and preserving their character and sense of place. Parksville, TN is located in extreme southeast Tennessee and is a gateway community to the Cherokee National Forest and the Ocoee River, one of the premier whitewater rivers in the eastern United States. Many rural gateway communities, like Parksville, lack planning and growth strategies. For this reason, among others, they are particularly vulnerable to haphazard growth and development that threaten their economic potential as well as their character and sense of place. The struggles, problems, opportunities, and solutions for gateway communities are explored in this thesis to determine planning and design mechanisms applicable to Parksville. The product of this thesis is a master plan for growth and development as well as conservation and preservation. Embedded in the plan are strategies and mechanisms to build upon and improve the local economy and safeguard natural, cultural, and historic resources. “Proactive Stewardship Planning” is suggested as a useful term to accomplish these ideals.

An environmental assessment of community college faculty satisfaction

Jackson, Sonja Peters 01 January 2000 (has links)
This study sought to determine the perceptions and satisfaction of individuals employed as full-time teaching faculty in a multi-campus two-year public postsecondary institution. The Personal Assessment of College Environment (PACE) survey instrument developed by Dr. George A. Baker III was used to collect responses to 55 items in regard to the environmental elements of formal influence, communication, collaboration, organizational structure, work design and student focus. The aforementioned elements were investigated to determine ( a) the current level of faculty satisfaction; (b) the extent to which perceptions differed among division affiliations; ( c) the extent to which perceptions differed between campuses; and ( d) the extent to which perceptions differed when gender, ethnicity, years at Polk Community College or level of education were considered. Findings showed that faculty were generally satisfied with the climate of the institution overall. Faculty in the Math, Science and Health division were less satisfied than others with the organizational structure element of the environment. Male faculty members were generally less satisfied than their female counterparts with the environment. Faculty who had been at the college less than one year rated the highest levels of satisfaction overall.
