    Monitoring Wells at Lemon Lane

Landfill operations were typical of the period with the absence of controls and design features common to modern facilities. No liner or cover was used. Dumping was not controlled with regard to waste content or record keeping. Scavenging and burning were common daily practices. Local residents routinely scavenged capacitors on or from the site To ensure salvagers would not interfere with dump operations, items such as capacitors would be placed at the south and west edges of the landfill where scavenging activities would occur.

In 1987, interim removal and remedial measures were implemented to minimize any immediate threat to public health and the environment. Surface capacitors were removed and eroded slopes were graded and stabilized. Clean fill was placed over the landfill surface followed by a 36-mil Hypalon geomembrane cover. The interim cover was maintained by Viacom until 2000, when Lemon Lane was excavated and capped.

Even though removal and consolidation activities have been completed, PCBs continue to be released at the Illinois Central Springs, where the EPA has built a 1000 gpm water treatment plant. Viacom, the responisble party, has refused to pay for the plant, prefering to perform dye and pump testing at the Landfill in hope that they could reduce the flow of PCBs at ICS.

Viacom's tests of November 2001 revealed several interesting facts. When pumping was conducted at MW-21 the PCB levels actually rose at ICS. [By lowering the amount of water getting to ICS, the concentrations of PCBs went up.] Unambiguous detections of fluorescein in several Valhalla wells (OO370, NN300, NN300A, OO300 and OO300A) indicate that epikarst flow from the LF-6 area (where there are high PCB levels) is predominately southwest, towards the ICS, although there may be layers where the water moves to the northeast as well. The travel time to ICS was 21 hours at 170 gpm average flow rate
