Ecological risk assessments evaluate the adverse effect to ecological and human receptors from exposure to hazards or one or more stressors.  Perennial performs assessments that provide the critical elements needed to determine the appropriate approaches to select a course of action.

These assessments have a flexible process for organizing and analyzing data, information, assumptions, and uncertainties to evaluate the likelihood of adverse ecological effects. We perform well thought out contaminant and ecological receptor research to prepare ecological risk assessments with the utmost quality so our clients can implement the best course of action based on state and federal objectives.
