ENRTF ID: 105-B Project Title: Cold Temperature Ammonia Consuming Bacteria during Wastewater Treatment Category: B. Water Resources Summary: This project will investigate ammonia consuming microorganisms during municipal wastewater treatment in the winter. These bacteria protect Minnesota’s environment by preventing the release of ammonia and estrogenic hormones. Total Project Budget: $ 462,351 Proposed Project Time Period for the Funding Requested: June 30, 2023 (3 yrs) Name: Timothy LaPara Sponsoring Organization: U of MN Department: Department of Civil, Environmental, and Geo-Engineering Address: 500 Pillsbury Drive SE Minneapolis MN 55455 Telephone Number: (612) 624-6028 Email lapar001@umn.edu Location: Statewide Alternate Text for Visual: This project will benefit the State of Minnesota and its environment by better understanding the bacteria that consume ammonia during wastewater treatment. It will lead to reduced fish toxicity and reduced feminization of fish populations by leading to better year-round ammonia removal.
