AGREMAX is a partially solidified mixture of coal combustion fly ash and bottom ash. Under the request of the United States Environmental Protection Agency (US EPA) Region 2, the US EPA Office of Research and Development (ORD) has performed two of the leaching tests contained in the Leaching Environmental Assessment Framework (LEAF) on subsamples of AGREMAX sampled from the AES Puerto Rico L.P. coal-fired power plant in Guayama, Puerto Rico. Subsamples of AGREMAX were collected and shipped under chain of custody to ARCADIS-US, Inc. (ARCADIS) serving as the onsite contractor for the EPA ORD Air Pollution Prevention and Control Division. Homogenized samples of the solid material were tested to characterize leaching behavior of AGREMAX during pHdependent leaching using Method 1313 and liquid-to-solid ratio (L/S)-dependent leaching in a percolation column using Method 1314. Method 1313 was conducted at EPA's Research Triangle Park Laboratories by ARCADIS while Method 1314 was performed at Vanderbilt University (VU). Leaching test eluates were analyzed for nearly 40 target analytes including major, minor and trace constituents.
