Key Takeaways The City of Wichita Falls, Texas, has experienced 13 taste and odor (T&O) events in the past five years, with one especially significant cyanobacterial bloom occurring in 2020. Thanks to Cypress Environmental Laboratory's thorough and effective T&O monitoring program developed in 2016, in each of the 13 cases, drinking water with elevated T&O concentrations was detected and treated before being released to the public. Laboratory staff further improved the monitoring program in January 2021, learning from steps they took to address an odor in the water at one of Wichita Falls' treatment plants.
