  1. UMass Environmental Engineering Research ProjectUse of Denitrifying Bioretention Systems to Control Non-Point Sources of Nitrogen Principal Investigators • Sarina J. Ergas and SukalyanSengupta (UMass Dartmouth) Sponsor: • Cooperative Institute for Coastal and Estuarine Environmental Technology (CICEET) Duration: 9/06 – 9/09 Synopsis: Laboratory and field studies of transformations of nitrogen in sulfur and wood chip based biological nitrifying/ denitrifying bioretention systems. These novel reactors are being developed to control non-point sources of N from agriculture. Graduate Student: Ryan Siegel • Siegel, R., Sengupta, S. and Ergas, S.J.
