Site Location: Cranbury, New Jersey
Contaminants: Nitrate and Ammonium in Soil and Ground Water that is 15 to 20 feet below ground surface.
Project Objective: Reduction of nitrate and ammonium plume in the downgradient aquifer
Implementation Program: The TreeMediation program was implemented to create a border that would limit the off-site migration of the contaminant plume in a "tight" sandy-clay aquifer.
Results to Date: Trees have consistently grown at a rate of between 6 and 8 feet per year. Results of five years of annual sampling indicate significant contraction of the nitrate and ammonium plumes in the downgradient aquifer.
