Subject: [CPEO-MEF] PERCHLORATE: Biotreatment of drinking water in Rialto, CA
[When the perchlorate contamination issue first burst on the scene several years ago, government agencies were reluctant to approve the biotreatment of drinking water, as opposed to groundwater. They feared public reaction. I argued that the public would favor biological methods, as long as used properly. Here, finally, is our chance to find out. - LS]

Work begins on cutting-edge plant project for Rialto's polluted groundwater

RIALTO - Work has begun on a $19 million project that will use naturally occurring microbes to clean up contaminated groundwater for nearly 17,000 people.

Texas-based Envirogen Technologies Inc. has begun building two giant stainless-steel tanks to be used as bioreactors.

In those tanks perchlorate-eating bacteria will turn hazardous groundwater in Rialto into quality drinking water, said Todd Webster, an environmental engineer with Texas-based Envirogen Technologies Inc.

Since its detection in 1997, a perchlorate plume in the Rialto-Colton basin has continued to move through the aquifer, resulting in the shutdown of nearly a quarter of Rialto's 22 wells, Envirogen said in a statement about the project.
