and is located about 100 feet east of the Mississippi
River west of Wood River in sec 33, T5N, R9W. The design
capacity of the well field is 5000 gpm or 7.2 mgd.
The position of the recharge boundary and the area
of infiltration for the design capacity were determined
by the process of trial and error. Several positions of
the recharge boundary were assumed, and drawdown

River-Bed Areas of Infiltration to Well Fields
Four well fields in the East St. Louis area are located
close to the Mississippi River and derive most of
their recharge from the induced infiltration of surface
water. The well fields are south of Alton in the Duck
Lake area, near the confluence of the Wood River and
the Mississippi River, west of Wood River, and west of
Monsanto as shown in figure 57.
One well field consisting of a collector well and two
artificial pack wells is owned by the Shell Oil Refinery
