March 25, 2009 - The city council gave its verbal support Tuesday to AmerenIP's plan to clean up a former manufactured-gas plant site at Fifth and Hill streets, starting in mid-April.
"We do not believe for one second it is safe to leave that contaminated groundwater in place," said Claudia Lennhoff, an organizer with the Fifth & Hill Neighborhood Rights Campaign.
Lennhoff alleged that other sites across the country have had problems with dangerous vapors being released from the ground from contaminated groundwater beneath. She said AmerenIP needs to be doing indoor vapor intrusion testing of homes in the neighborhood to make sure that isn't happening now. And she alleged groundwater could eventually recontaminate the soil, even though Ameren plans to excavate the top 10 feet of soil on the north half of the site.
