Here we are at the front door of the Illinois Central Springs Water Treatment Plant, where the springwater is put through the process of removing PCBs.
Let's start at the Illinois Central Spring, and follow the water from where it leaves the ground, to the plant where it is treated to remove the PCBs, and on downstream to where it joins the east branch of Clear Creek.
Here is the spring, and you can see the sampling station Viacom has built above springhead. They recently sampled during a May storm event (when the PCB concentrations are the highest.)
When the railroad was built, the spring water was piped under the tracks, where it seemingly emerged from the stones and railroad timbers and down this overgrown channel. (Trains used to stop at the spring to fill their water tanks.)
Now it is piped directly to the pumphouse sump...
Under the pumphouse floor is the 3500 gallon sump, where the water is stored until it is pumped to the plant or the storage tanks. There are 3 sets of redundant pumps, and they run at 200, 800, and 2500 gallons per minute (gpm) respectively. They can handle up to 3500 gpm, and have had no problems handling the water flow to date.
At the rear of the building is a sump overflow door. Since the storage tanks have been installed, the sump has not overflowed, as the pumps are quite adequate for storm events.
Here are the two storage tanks that store water during strom events. As the plant itself can process 1000 gpm, and storm events can generate 10 times that amount, storage is a necessity. The problem that has emerged is that Bloomington is subject to storms nearly every month of the year that exceed the capacity of the storage tanks.
This plot next to the other two tanks already has the piping in place to build another tank. EPA and Viacom are in negotions, and this issue is no doubt on the table. Viacom has not paid for the treatment plant, claiming it is oversized. They have continued dye and pump testing at southeast corner of Lemon Lane, where they hope to pump and treat water there. So far their investigations have not produced data that supports their contention that pumping at the Landfill can reduce the flow of PCBs at ICS.
Here is the Backup Generator, and IDEM supervisor Jessica Fliss. The generator has been used several times during electrical outages, and can produce 62 KW of power. Backup fuel is always on hand, as when the electricity is most likely to fail (during storms), this is the very most important time for the plant to be operating at full capacity.
