Controlling odor from EDB

With all the rain we have had this summer a lot of EDB were underwater for long periods of time. Now that it has started to dry out I have been getting a lot of complaints about the odor associated with the basin.
Is there anything that can be done to reduce or eliminate the smells?
Thank you.

    Unfortunately, I don’t know of a simple solution to this problem. The odor issues may be due to decaying organic matter and/or other complex reactions occurring within the sediment captured by the EDBs. Such reactions generally occur only after the water column becomes anaerobic (i.e. low oxygen levels) which can take several days to occur in an EDB with stagnant water. Since EDBs are designed to drain within 24-72 hours, I suspect that the primary issue is that the EDB outlet structure is clogged, creating stagnant water issues. To avoid this issue in the future, make sure that the outlet structure is maintained regularly. You may also have to remove some sediment from the EDB.
