- An Assessment of Metals Distribution and Transport in Groundwater Beneath the Diked Sediment Disposal Area, DePue Wildlife Management Area, Illinois [RR-110]
Potential toxic metal (Zn, Cd, Pb, Cu) contamination of groundwater at the periodically flooded DePue Dredged Sediment Disposal Area (DSDA), was assessed through the collection of groundwater and soil samples and water level data, geochemical modeling, and leaching and microcosm experiments. The median Zn concentrations in groundwater at three locations were between 2 and 5 mg/L. There was no evidence that contaminated groundwater has migrated offsite. Based on lake-sediment and soil data, the order of decreasing mobility in the site groundwater was Zn > Cu > Cd > Pb. Small amounts of Zn and Cd (< 2%) were leached from soil samples inside the DSDA in leaching experiments. About half of the dissolved Zn and Cd from groundwater samples can be accounted for by leaching, suggesting desorption was a major control for Zn and Cd. Chemical equilibrium calculations indicated that several reactions, including CdCO3 precipitation, coprecipitation of Zn with CaCO3, and sorption to ferric oxide, may retain the metals in the subsurface. Aqueous Zn concentrations were greatest in aerobic microcosms, lowest in sulfate-reducing microcosms, and intermediate in iron-reducing microcosms. Zinc would thus be expected to be most mobile in DePue soils during the early stages of flooding, when the soils are saturated but before conditions become anaerobic. - Applicability of Microfiltration for Recycling Semi-Synthetic Metalworking Fluids [RR-111]
This research seeks to investigate the applicability of microfiltration technology by investigating the membrane fouling mechanisms at work in the system. It also aims to reduce fouling through adjustment of operating parameters and the design of a new semi-synthetic MWF that significantly reduces the impact of membrane fouling. - Arsenic Geochemistry and Distribution in the Mahomet Aquifer, Illinois [RR-107]
Groundwater samples were collected from approximately 50 private wells in Tazewell County, an area where arsenic contamination is known from previous sampling, and northwest Champaign County, an area for which very few arsenic data were available. Most of the wells were finished in the Mahomet Aquifer, with roughly equal numbers of wells near the bottom, middle, and upper part of the aquifer. A few of the wells were finished in the Glasford Aquifer, which lies above the Mahomet. A reliable, robust method for arsenic speciation was developed based on separation of species by HPLC and ICP-MS detection. The samples were analyzed for total arsenic, arsenic species, metals, anions, alkalinity, ammonium, and total organic carbon. Samples of raw groundwater and finished potable water were collected from 11 municipal water treatment plants that withdraw water from the Mahomet Aquifer. - Biodiesel Research: A Bibliography and Finding Aid [WMRC TN06-085]
Biodiesel burns cleaner (i.e. produces fewer emissions) than traditional petroleum diesel fuel and is biodegradable, making it an interesting alternative fuel option in terms of both environmental protection and U.S. energy independence. Biodiesel fuels most commonly available are really blends of biodiesel and petroleum diesel (B20, or 20% biodiesel, 80% petroleum diesel, for example). An American Society of Testing and Materials (ASTM) standard does exist for biodiesel (ASTM D6751). The intended audience for this publication is scientists and engineers interested in the technical aspects of biodiesel formulation and use. - Calumet Eco-Industrial Network Survey Project: Partnership Opportunities for Reusing Materials, Water, and Energy [RR-102]
The Calumet Eco-Industrial Network Survey Project was conducted to collect baseline information for the purpose of developing an Eco-Industrial Network in the Calumet region of Chicago. Southeast Chicago Development Commission (SCDCom) believes that local companies can utilize the basic principles of material re-use, waste reduction, and energy efficiency within networks of companies. Information gathered from this survey project could be a first step in creating an Eco-Industrial Network (EIN) between local companies in the Calumet region. - Celebrate Earth Day
The first Earth Day was held on April 22, 1970, the same year that President Richard Nixon signed the legislation that created the U.S. Environmental Protection Agency. Its founder, Senator Gaylord Nelson, envisioned it as a grassroots celebration that would raise awareness of environmental issues. In celebration of the 35th anniversary of this historic event, Illinois Waste Management and Research Center Library would like you to visit the following sites to learn more about it and get ideas for making Earth Day every day. - Chemical Management Services - Focused Studies: Part 1. CMS in Small and Medium Enterprises, Part 2. A CMS [RR-104]
This report covers two aspects of efforts to increase adoption of chemical management services (CMS). The first is expansion of CMS into small and medium enterprises (SMEs). The second is reducing uncertainty among chemical users through a CMS "standard." A review of existing standards in other industries reveals five basic dimensions that must be considered in structuring a CMS standard. Three alternative structures for the CMS standard are proposed. - Concentrations and Potential Toxicity of Metals and Ammonia in Peoria Lake Sediments and Pore Waters (covers Sampling period: April and October 2000) [RR-103]
The concentrations and potential toxicity of several heavy metals (cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) and ammonia in sediments and pore waters of Peoria Lake to 30 cm depth have been characterized. - Concentrations of Selected Elements, Physical Condition, Reproductive Activity, and Demographic Patterns in Small Mammals Inhabiting DePue Wildlife Management Area (covers Sample collection during September 1998 and 1999.) [RR-101]
The objectives of this study were: 1) examine if concentrations of selected elements in the tissues of small mammals inhabiting DePue Wildlife Management Area were elevated relative to those collected at reference sites; 2) compare concentrations of selected elements in the tissues of small mammals from DWMA with critical levels observed in previous studies, and 3) compare the abundance, demographics, reproduction, and health indices of white-footed mice from DWMA with those collected at reference sites. - Environmental Information: Trends and Issues (2006)
