Based on d provided, the vadose zone at the Fink Landfill is <br /> 5 comprised of interbedded silt, clay, and sand intervals down to the saturated sediments at <br /> Approximately 40 to 45 feet below grade. Lsvine'Frlcke was not provided with an attenuation <br /> factor for the Fink Road landfill and we have, therefore, used 100 as the attenuation factor as a <br /> conservative value. <br /> The calculation for this determination is as t 6ws. <br /> Attenuation factor, multiplied times the war quality goal for the constituent of concern, divided <br /> by 10, divided by I(10. <br /> For barium the water quality Zoal is 1,000 p m, therefore the following equation determines the <br /> concentration of barium that the Fink Road ndfill can accept, if their attenuation factor is 100 <br /> 100x 1.000/10/1.000-10 ppm <br /> For copper, the water quality goal is 200 ppm. Therefore, the following equ ioR determines the <br /> concentration of copper that the Fink Road ndfill can accept. if their attenuation factor is 100 <br /> 100 x 200/10/1,000=2 ppm <br /> Based on the anah tical results of the three s mples of bottom ash in comparison to the designated <br /> level methodology, the bottom ash material s not considered a designated waste. <br /> If you have an,. quesnons or need any more information please call me or Maya Rappaport <br /> Sincerely <br /> V � <br /> Ron Ooloubo+v <br /> Senior Project Geologist <br /> enclosure <br /> cit J.
