Water contamination has been a long-standing issue in Coronado due in part to pollution from the Tijuana River Valley in Mexico, which flows to area beaches and causes significant closures to the shoreline.

Navy SEALs are training in sewage-contaminated water. Now, a government watchdog is calling out the heads of the elite program that trains just off the coast of Coronado.
