UPDATE: Mercury Spill Cleanup Plans At Clinton, IA Plant

UPDATE

The Iowa DNR says the Archer Daniels Midland Company has submitted a site-assessment plan, taking a look at the situation and what it can do moving forward. 

The spill happened back in November when crews were pulling a pump from the company's private well. Some mercury was recovered, but it's believed some is still missing.
     
One proposal from ADM is to use a camera in the well to locate the mercury but the plan is still under review.
     
There are also other private wells on the property with the same type of mercury seal on the well-pump motor. The company plans to replace those with mechanical seals.

CLINTON, Iowa (AP) - The Iowa Department of Natural Resources says a more than a pound of highly toxic mercury was spilled at a corn processing plant in eastern Iowa.

The agency says in a news release Friday that the mercury was spilled Wednesday at an Archer Daniels Midland Company plant in Clinton.

The spill occurred as a contractor was pulling a submersible pump from a 1,400-foot-deep well. A seal broke, allowing mercury to fall onto the ground and into the well.

More than a pound of mercury was recovered from the soil. The submersible motor is being sent for repairs and to determine how much mercury remains in the motor.

The company has hired a contractor to recover mercury released into the well.

Mercury can cause severe kidney and neurological problems in people.
