Jefferson Township, Ohio -- A consultant hired by Montgomery County says a

company planning to dispose of a byproduct created by the

destruction of a deadly nerve agent needs to retest its disposal

process.

Bruce Rittmann is a professor of civil and environmental

engineering at Northwestern University.

He was hired to evaluate the safety of a Dayton-area company's

plan to dispose of 300-thousand gallons of a chemical byproduct of

the destruction of V-X nerve agent.

The Army has proposed awarding Perma-Fix a 9 (m) million dollar

contract to get rid of the chemical.

Perma-Fix has already done tests with small quantities of the

chemical.

Rittman said Perma-Fix only monitored the beginning and end of

the process and failed to show the entire process worked as

planned.

He says the tests should be redone.

An army spokesman says the findings will be considered.
