From the Lead Lab archive:
A trash and ash deposition location was discovered along Bayou St. John directly across the street of the U.S. Post Office, and along Jefferson Davis Parkway between Lafitte Street and Orleans Avenue. The photos illustrate the exposure and cleanup of the dumpsite in the summer and fall of 1998.
