Volume 85, no. 7, e02956-18, 2019, https://doi.org/10.1128/aem.02956-18. Fig. 6. The Ct value for monochloramine (MA) treatment of Cu biofilms should read “76” rather than “68,” and the Ct value for free chlorine (FC) treatment of PVC biofilms should read “64” rather than “76.” The figure should appear as shown here.
