ASUNCION, Paraguay (AP) — Paraguayan officials warned on Thursday of a possible environmental disaster because a flooding river is threatening a dump site for toxic residues.

State environmental chief Marina Cristina Morales said the Paraguay river already has flooded the Cateura dump in the capital city of Asuncion. The river has risen nearly 6.5 feet (2 meters) above normal, though it was still 9 feet (2.8 meters) below the level of a containment site for toxic waste.
