Alternative landfill soil/vegetation covers at Rocky Mountain Arsenal: could difference in plant roots between covers contribute to differences in cover function?

Abstract

In May 2015, the Army notified Regulatory Agencies that the amount of water collected by Lys 001 and Lys 002 on the Shell Disposal Trench RCRA-equivalent cover exceeded the compliance standard of 1.3 mm/yr (Navarro report, 17 Sep 2015). The purpose of the project reported here is to Investigate root development as possible contribution to this excessive percolation.
