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.

The Navy did not follow beach closure advisories, exposing Navy SEAL candidates and possibly affecting training, a government watchdog found.

A Navy Seal who led a strenuous workout that sent nine Tufts University lacrosse players to the hospital appears to have lacked the credentials to supervise the group exercise.
