Dredging Research: Information from the Engineer Research and Development Center. Volume 7, Number 2

Abstract

Ammonia is a common contaminant of concern in effluent at confined disposal facilities (CDFs). Ammonia is generally present in the dissolved form and therefore is not removed by sedimentation processes in the CDF. Ammonia becomes an issue for 401(b) water quality certification because USEPA and the states have water quality criteria and standards for ammonia in receiving waters based on toxicity to aquatic organisms. Compared to concentrations commonly occurring in CDFs, the ammonia standard of 2-7 milligrams per liter (fresh water depending on temperature) is very low. Ammonia nitrogen also provides an oxygen demand within the CDF and receiving waters that may become a water quality compliance issue.
