Description of Requirements

1.0 BACKGROUND

The Environmental Laboratory (EL) is recognized worldwide as the problem solver in environmental science and engineering research for US Army, the Department of Defense, and the Nation. R&D activities address a multitude of environmental issues to advance civil works, water resources, military installations, and the warfighter. Research activities include ecosystem restoration, ecological resources, and contaminant management, risk and decision science, environmental sensing, ecological modeling and forecasting, environmental security, and environmentally sustainable material.

The instruments purchased must meet the specifications outlined below so that data gathered from previous experiments with identical equipment can be validated for use with data gathered on future experiments within the same projects for use in future journal articles and research publications.
