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.

This document is intended to lay the foundation for resource reduction strategies in new construction, renovation and demolition. If you have an innovative idea or information that you believe should be included in future updates of this manual please email Shelly Codner at scodner@region12cog.org or Jan Loyson at Jan.Loyson@Iowalifechanging.com. Throughout this manual, we use the term “waste reduction” to define waste management initiatives that will result in less waste going to the landfill. In accordance with the waste management hierarchy these practices include reducing (waste prevention), reusing (deconstruction and salvage), recycling and renewing (making old things new again) - in that order. This manual will explain what these practices are and how to incorporate them into your projects.

The technology used in this proposal is Bioprocess Algae’s Vertical Mounted Photo bioreactor.  Inputs to this system are CO2 from a rich source, here an ethanol plant, nutrients, wastewater from the ethanol  plant, sunlight and waste heat if available.  The outputs from this system are algae oil, which is similar to  other vegetable oils, dilapidated algae meal, and dry whole algae.  Application use of the oil will be  biodiesel feedstock, an alternative feedstock for ethanol or as a feedstock for other energy production  processes.

This letter has been prepared as a consultation to evaluate human health impacts from the use of private drinking water wells in Clinton County, Iowa. These wells are located just to the west of Highway 67 and Camanche, Iowa and near 9th Street, 31st Avenue, and 37th Avenue. The wells are also located to the south of contaminated sites known as Chemplex and PCS Nitrogen, and near former disposal areas known as Todtz Landfill and Doty Landfill. The Iowa Department of Public Health’s priority is to ensure the Clinton County community has the best information possible to safeguard its health. That information is included in the following paragraphs.

A waste sort is a process of hand-sorting onsite waste in order to quantify the amount and type of solid waste generated by businesses, organizations and municipalities to determine how much waste is ultimately ending up in the landfill. Data from waste sort events assists in identifying current waste practices and the feasibility of implementing commodity specific waste reduction, recycling and education programs.
