Health consultation : Contamination of sump within residential property, Carroll County, Iowa (2007)

The Iowa Department of Natural Resources (IDNR) has been involved in an investigation surrounding the appearance of an unknown oil within the sump in the basement of a residence in Carroll, Iowa. The IDNR has requested the Iowa Department of Public Health (IDPH) to prepare a health consultation regarding their investigation. The IDPH, in cooperation with the Agency for Toxic Substances and Disease Registry (ATSDR), prepared this health consultation to review the current status of the IDNR investigation and to provide an evaluation of the public health implications of exposure to the unknown oil within the sump. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

An Architectural and Historical Survey of Public Libraries in Iowa 1870-1940, 1980

The public library movement f the early twentieth century was a national phenomenon, in which Iowa, along with its neighboring states, played a prominent role. In 1900, the Iowa Library Commission noted 48 free public libraries in the state. Today there are approximately 500, in towns ranging in size from Beaman, with a population of 222, the Des Moines, the state capitol. Iowans took enthusiastic advantage of Andre Carnegie's library philanthropy. In 1919, the Carnegie Corporation stopped funding libraries, 101 building has been erected in Iowa with Carnegie funds. Iowa place fourth among the states in terms of the number of communities obtaining Carnegie buildings, fifth in dollar appropriation per one hundred population and eighth in the total amount of money given by Carnegie to a state. These figures provide some measure by which interest in popular education among Iowans of the period can be judged. Today these early libraries, often the most distinctive public libraries in small or medium-sized towns, are physical foci in the townscapes of their communities and centers for a variety of educational and social activities. This survey was initiated by the Division of Historic Preservation in 1977. It grew out of the need to provide a framework within which libraries could be evaluated for National Register action. Several libraries (Des Moines, Grinnell, Eagle Grove, Carroll) has been recent candidates for the Register. There was every indication that enthusiasm for old library buildings was increasing and that more nominations could be expected in the future. The attrition rate among early library buildings was (and is) growing. Most libraries were built on limited budgets (Carnegie did not squander his money) and, despite the fact that future expansion was usually a conscious consideration in their design, they are rapidly becoming obsolete, due to expanding collections and changing styles of librarianship. If the protection of the threatened with demolition or alteration, action needed to be taken.

Pieces of Iowa’s Past, February 6, 2013

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Women’s and Children’s Building BACKGROUND: 35TH IOWA GENERAL ASSEMBLY The Thirty-fifth General Assembly convened January 13 and adjourned April 19, 1913—a 97-day session. Edward Cunningham was Speaker of the House and William Harding was the Lieutenant Governor presiding over the Senate. The Senate had 18 Democratic members and 32 Republican members. The House of Representatives had 66 Republican members and 42 Democratic members. There were a total of 158 members in the General Assembly. Governor Beryl Carroll finished his term in January 1913 and Governor George Clarke was sworn in on January 16, 1913. He was 60 years old. The 1910 federal census showed Iowa’s population at 2,224,771.

All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained THIS WEEK: Iowa State Capitol Structural Sandstone Origination From The Iowa Capitol Commissioners Reports Report of Capitol Architect A.H. Piquenard, submitted December 16, 1875 BACKGROUND: The Ste. Genevieve sandstone is the buff color stone on the exterior of the Capitol. The Carroll County sandstone was the light color or contrast stone on the Capitol exterior. The Carroll County stone did not wear well and was removed from the building during the exterior renovations in the 1980s and 1990s. Both sandstones are from Missouri.

Floods of 1986 and 1990 in the Raccoon River Basin, West-Central Iowa, HR-140, 1992

Water-surface-elevation profiles and peak discharges for the floods of 1973 and 1979 are compared to those of 1986 and 1990 in the Raccoon River basin, west-central Iowa. The profiles illustrate the 1979 and 1986 floods on the Raccoon, South Raccoon, and Middle Raccoon Rivers, the 1973 and 1986 floods on Walnut Creek, and the 1986 flood on Willow Creek and Mosquito Creek. The 1986 flood is the largest on record at U.S. Geological Survey streamflowgaging stations on the Middle Raccoon River tributary at Carroll, Middle Raccoon River near Bayard, Middle Raccoon River at Panora, and Walnut Creek at Des Moines. The 1990 flood discharge is the largest on record at U.S. Geological Survey crest-stage gaging stations on Hardin Creek near Farlin and on East Fork Hardin Creek near Churdan. The flood history given in this report describes rainfall conditions for floods that occurred during 1986 and 1990. Discharge for the 1990 flood on East Fork Hardin Creek near Churdan was 1.01 times larger than the 100-year recurrence-interval discharge.

Investigation of Steel-Stringer Bridges: Superstructures and Substructures, Volume I, TR-522, 2007

There are hundreds of structurally deficient or functionally obsolete bridges in the state of Iowa. With the majority of these bridges located on rural county roads where there is limited funding available to replace the bridges, diagnostic load testing can be utilized to determine the actual load carrying capacity of the bridge. One particular family or fleet of bridges that has been determined to be desirable for load testing consists of single-span bridges with non-composite, cast-in-place concrete decks, steel stringers, and timber substructures. Six bridges with poor performing superstructure and substructure from the aforementioned family of bridges were selected to be load tested. The six bridges were located on rural roads in five different counties in Iowa: Boone, Carroll, Humboldt, Mahaska, and Marshall. Volume I of this report focuses on evaluating the superstructure for this family of bridges. This volume discusses the behavior characteristics that influence the load carrying capacity of this fleet of bridges. In particular, the live load distribution, partial composite action, and bearing restraint were investigated as potential factors that could influence the bridge ratings. Implementing fleet management practices, the bridges were analyzed to determine if the load test results could be predicted to better analyze previously untested bridges. For this family of bridges it was found that the ratings increased as a result of the load testing demonstrating a greater capacity than determined analytically. Volume II of this report focuses on evaluating the timber substructure for this family of bridges. In this volume, procedures for detecting pile internal decay using nondestructive ultrasonic stress wave techniques, correlating nondestructive ultrasonic stress wave techniques to axial compression tests to estimate deteriorated pile residual strength, and evaluating load distribution through poor performing timber substructure elements by instrumenting and load testing the abutments of the six selected bridges are discussed. Also, in this volume pile repair methods for restoring axial and bending capacities of pile are developed and evaluated.

07014-005 Maple River Watershed Final Report

The proposed project will include the construction of a sanitary sewer collection system and a community gravel filter wastewater treatment system in the unsewered community of Maple River Junction in Carroll County. The system will be built to include approximately 1,150 feet of 4-inch sanitary sewer main, 3,540 feet of 4-inch service main an approximately 35 septic tanks. Some existing 4-inch PVC sewer piping as well as existing septic tanks in good condition will continue to be used in order to control capital costs.
