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.

James K. Polk and Slavery

Marsh, Richard Dean 08 1900 (has links)
As a plantation owner, James K. Polk had economic interests which were bound to that peculiar institution. Consequently, many of his decisions as a politician were influenced by his southern background. Although his partiality toward"southern rights" was evident, he did not let his personal bias interfere with his determination to preserve the nation. Throughout his public career, he maintained that slavery was being exploited as a "political question" to divide the United States. Even though his opponents branded him a "sectionalist" for his position on the issues of Texas annexation, the Mexican War, and slavery in the territories, he still remained a staunch nationalist. This study proves that James K. Polk's "southern convictions" were secondary in importance compared to his concern for the preservation of the Union.

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.
