Corps monitors seepage under levee

ALTON - Engineers returned Monday to wetlands along the River Heritage Parkway to pluck more data about pressure from under-seepage from the Mississippi River, which could be carrying sand under the Wood River Levee.

Geotechnical engineers from the U.S. Army Corps of Engineers' St. Louis District are taking readings recorded every four hours by eight piezometers, which measure water pressure.

"They are connected to a handheld logger," with engineers also observing the seepage areas and small underwater sand boils in person, said Travis Tutka, levee safety program manager for the corps.

Tutka said with normal river conditions, such as now, the engineers will be going out weekly to the wetlands, north of the parkway (Illinois Route 143, commonly known as the Berm Highway).
