Progress Report Objectives (from AD-416) Study the beneficial use of FGD gypsum as a beneficial soil amendment for use in alfalfa agriculture. Approach (from AD-416) Conducting research on Wisconsin Energies (WE) Kenosha, Wisconsin Generating Plant FGD gypsum as part of a grant administered by Electric Power Research Institute (EPRI) and the Ohio State University. A field study was conducted at Kingman, Indiana on 2.2 acre plots according to the protocol of Flue Gas Desulfurization (FGD) Gypsum Network in 2008-2010. Plant samples, water samples and soil samples were collected and analyzed as per the protocol in 2008 and 2009. The site was continued into 2010 and yield collected for all three years following application of FGD gypsum and mined gypsum. Data analyses were performed on the final data set collected from the Kingman, Indiana field site and a report written. FGD gypsum from the Kenosha power plant of Wisconsin Engergies (WE) was applied to field plots on the University of Wisconsin Arlington Research Station on a Plano silt loam soil in 2010. The plots were planted to alfalfa and yield measured and plant tissue samples taken at the first and second cuttings in 2009-2010 and the first cutting in 2011. Soil samples before and after application were taken for analysis of heavy metals including mercury. Shallow groundwater samples were collected at 60cm depth using lysimeters throughout the growing season. This research was conducted in cooperation with the Ohio State University, WE Energies, the Electric Power Research Institute and University of Wisconsin, Madison. This project is completed, data is being compiled and papers will be finalized shortly for publication in scientific journals. Activities of this project were monitored through annual reports and periodic personal meetings at scientific conferences, phone calls and e- mails. This is the final report as the project has ended.

Progress Report Objectives (from AD-416) Study the beneficial use of FGD gypsum as a beneficial soil amendment for use in alfalfa agriculture. Approach (from AD-416) Conducting research on Duke Energy's Cayuga Generating Plant FGD gypsum as part of a grant administered by Electric Power Research Institute (EPRI) and the Ohio State University. Significant Activities that Support Special Target Populations FGD gypsum from the Gibson Power Plant of Duke Energy was applied to 28 - 1 ha (2.2 acre) plots at a field near Kingman, Indiana and shallow water table, soils and corn plants were analyzed for a variety of parameters. Corn yield was also measured. A rainfall simulator experiment was conducted on the same field to measure water quality of runoff. A second site with 28 plots was established at the Arlington Station of the University of Wisconsin to similarly study the effect of FGD gypsum on alfalfa. This project was in cooperation with WE Energies, Kenosha Power Plant. Both sites are in cooperation with Ohio State University and the Electric Power Research Institute. Activities of this project are monitored through annual reports and periodic personal meetings at scientific conferences, phone calls and e-mails.

Progress Report Objectives (from AD-416) Study the beneficial use of Cayuga�s FGD gypsum as a beneficial soil amendment for use in corn/soybean agriculture. Approach (from AD-416) Conducting research on Duke Energy's Cayuga Generating Plant FGD gypsum as part of a grant administered by Electric Power Research Institute (EPRI) and the Ohio State University. Significant Activities that Support Special Target Populations A field study was initiated to compare mined pellitized gypsum and synthetic FGD gyspum on a farmers field near Kingman, IN. Randomized plots 24 rows wide and 2600 feet long were surface treated with 0, 300, 750 or 2000 lbs/acre pellitized gypsum or FGD gypsum. Soil samples were taken prior to application and planting to corn. Following planting lysimeters were installed at 60 cm depth and water samples taken for analysis of soluble nutrients and pesticides and heavy metals. This research contributes to National Program 201, �Water Resource Management,� Problem Area 6 "Water Quality Protection Systems."
