Once data have been entered into the SWAMP database and have undergone the SWAMP procedures for verification and transfer to the permanent side of the database, they are displayed on the California Environmental Data Exchange Network (CEDEN) website. For specific questions regarding the data, please contact the appropriate State or Regional Board Representative.
