Death by Nutrients: Toxicity of Ammonia and Harmful Algal Bloom (HAB) Events

Ammonia and other forms of nitrogen, along with forms of phosphorus, may contribute to harmful algal blooms. The U.S. Environmental Protection Agency has developed new ammonia toxicity criteria for states to adopt and enforce. This webcast provides background information on these topics, discusses how WEF members may be affected, and advises preparation and responses to new requirements that may emerge.

Coliform Analytical Methods and Data Application in Wastewater and Recreational Waters

Coliform tests are used as an indicator of wastewater disinfection and the health of waterways. Three of the most common analytical techniques for coliform analysis are membrane filtration, multiple tube fermentation, and defined substrate. The aseptic technique is critical to the success of any microbiology method. Learn the basic aseptic technique, details about these three microbiological analyses, ways to apply coliform results to ensure regulatory compliance, and guidance to make decisions about recreational waterway health.

Emerging Trends in Wastewater Disinfection

Learn about the latest findings from two ongoing Water Environment & Reuse Foundation (WE&RF; Alexandria, Va.) disinfection research projects during this joint Water Environment Federation (Alexandria) and WE&RF webcast. The first project examines factors influencing variations in ultraviolet disinfection performance and treatment capabilities. The second project evaluates use of peracetic acid for wastewater disinfection.
