National Ammonia Water Quality Criteria Survey

This survey is part of an Ohio Water Development Authority (OWDA) Research and Development Grant (#7179) sponsored by the City of Johnstown, OH and supported by Ohio EPA, OWEA, and several partnering POTWs.

The data generated under this project is intended to be used to gain a better understanding of the magnitude of impacts on activated sludge and other plants, including the ability of and cost for these and other types of systems to comply. The ability of systems to comply with new ammonia criteria and new nutrient criteria in Ohio through optimization of operations, or via alternative means such as upgrades to the existing treatment trains, is being quantitatively and qualitatively addressed in this project.

The response to the survey, together with the experimental field data currently being gathered, helps to address to key questions prior to new rulemaking in Ohio:

1) Can activated sludge and other types of treatment plants consistently meet US EPA’s new ammonia criteria?
2) At what cost?

This survey should take approximately 30 minutes to complete.


2) What are your NH3 limits?
