Health consultation : Iowa City former manufactured gas plant site, 505 Burlington Street, Iowa City, Johnson County, Iowa EPA facility ID: IAD984591172 (2006)

The United States Environmental Protection Agency (EPA) has requested the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to evaluate the health impacts of the proposed remedial strategy to be implemented at the Iowa City Former Manufactured Gas Plant Site (FMGP). The proposed remedial strategy to be implemented incorporates the following: 1) access restrictions through the continued operation of the Iowa-Illinois Manor and restriction on any future water well installation through continued implementation of a local environmental covenant; 2) previous site decommissioning activities that have restricted access to site contaminants; and 3) continued monitoring of the groundwater to ensure that contaminant levels in groundwater remain the same or are declining in concentration. This health consultation addresses potential health risks to people from exposure to the soil and vapors within the property. 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.

Letter health consultation : Doty Landfill site, Camanche, Iowa EPA Facility ID: IAD980497556 (2008)

The Doty Landfill encompasses 13 acres of land and is located in the southeastern quarter of Section 29, Township 81 North, Range 6 East, Clinton County, Iowa. The site was used as a landfill for municipal solid waste from 1970 to 1975. In addition, local residents have expressed concern that other chemical-or pesticide waste had been disposed at the site. Previous site investigations had been completed in 1992 and in 2005. In October 2007 water samples from private wells located in the vicinity of the Doty Landfill site were collected and analyzed for dissolved metals. Two of the water samples obtained from drinking water wells contained dissolved arsenic above the US EPA Maximum Contaminant Level (MCL) for arsenic of 10 μg/L (micrograms per liter) or 10 ppb (parts per billion). The water samples in question contained dissolved arsenic at concentrations of 19.3 and 14.9 μg/L or 19.3 and 14.9 ppb.

Health consultation : Climbing Hill groundwater contaminiation site, Climbing Hill, Woodbury County, Iowa (2004)

The Iowa Department of Natural Resources (IDNR) asked the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to perform a health consultation for the Climbing Hill, Iowa, groundwater contamination site. IDNR wants to know if the site poses a public health hazard. 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. Climbing Hill is an unincorporated town in Woodbury County, Iowa, approximately 15 miles southeast of Sioux City. The town has approximately 120 residents. All of the residents and most businesses within the town use private wells to supply their drinking water. The local restaurant has an individual well that is classified as a public water supply system because it has the potential to serve more than 25 people in a day. Several wells in the town have become contaminated with gasoline and diesel fuel leaking from two underground storage tanks. All of the wells are roughly 75–80 feet deep (R.
