Beginning on June 22, 2009, a road safety audit was initiated for the intersection of US 218 and County Road C-57 in Black Hawk County, Iowa. Due to the traffic volumes and the number of conflicting traffic movements on these two roadways, this intersection has developed a crash history that concerns the Iowa Department of Transportation (Iowa DOT), Iowa State Patrol, and local agencies. This intersection is ranked seventh in Iowa for the highest number of at-grade expressway intersection crashes. Considering this, Black Hawk County and the Iowa DOT requested that a road safety audit be conducted to address the safety concerns and recommend possible mitigation strategies.

The United States Environmental Protection Agency (EPA) has requested the Iowa Department of Public Health (IDPH) to evaluate the health impacts associated with exposure to contaminants of concern that have been found at the former Chamberlain Manufacturing Site. The EPA has been involved in the investigation and remediation of the Former Chamberlain Manufacturing Site since 2005. As part of these investigative activities, on-site soil sampling and both on-and off-site groundwater sampling has been completed. In addition, sub-slab soil gas, indoor air, and ambient air sampling at properties located near the Former Chamberlain Manufacturing Site has been completed. This health consultation addresses potential health risks to the public from exposure to the soil, groundwater and potential vapors within homes or buildings at or near the Former Chamberlain Manufacturing Site. 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.

The disposal of discarded tires has become a major problem. Different methods of recycling have been researched. Currently, Iowa is researching the use of ground recycled crumb rubber from discarded tires in asphalt rubber cement. Six projects have been completed in Iowa using asphalt rubber cement. This project is located on IA 947 (University Avenue) in Cedar Falls/Waterloo. The project contains one section with asphalt rubber cement used in both the binder and surface courses and one section using asphalt rubber cement in the surface course with a conventional binder. There are two control sections where conventional asphalt pavement was placed.
