This tool is needed to assist dischargers in successfully achieving compliance with new or updated water quality standards. It will be used to compare numeric criteria generated using the existing and proposed freshwater ammonia equations. These equations can be quite complex. Specifically, this tool will analyze pH, temperature, and ammonia water quality data collected from the State’s fresh surface waters (rivers, streams and lakes) and compare the ambient ammonia concentrations to the current and proposed freshwater ammonia SWQS. Inquiries made to the Bureau regarding ammonia criteria may be redirected to this application instead of having to be addressed by staff. This project aligns with the DEP’s objective of promoting transparency, efficiency, and innovation using technology.
