"Use of Denitrifying Bioretention Systems to Control Non-Point Sources of Nitrogen"

Principal Investigators: Sarina J. Ergas and Sukalyan Sengupta (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
