New Jersey officials are planning an update regarding the ongoing cleanup efforts of major portions of the Passaic River.   Rep. Bill Pascrell Jr. will be joined Monday by several other state and federal officials at the Diamond Alkali Superfund site in Newark to announce cleanup plans for that part of the river.

Two major chemical companies have been ordered to help pay for remediating the parts of the waterway, which was polluted by the former Newark pesticide manufacturing facility.

A state judge has found Tierra Solutions and the Occidental Chemical Corp. liable for cleanup costs on the former Diamond Alkali/Diamond Shamrock plant site.  But the amount those firms will have to pay likely won't be determined until at least 2013, due to ongoing legal actions.
