Have any wells in Anaheim been closed because of perchlorate contamination?
A. No wells in Anaheim have been closed because of perchlorate contamination. Some wells, in which perchlorate was detected, have been closed due to pump failures or other maintenance issues. The one remaining well in which perchlorate has been detected has been placed in stand-by mode, which means it will only be used if there is an emergency, such as a major fire.
