In 2004, both Illinois EPA and U.S. EPA investigated the location of a former battery cracking and recycling operation in Gilberts. The main site is located immediately north of the intersection of Railroad and Mill Streets bounded to Galligan Road on the east and the Chicago and Northwestern Railway on the west. It is in an area that is mostly wooded near both industrial and residential properties. Lead acid batteries were cracked open to recover the lead. Some of the lead seeped into the ground along with acid contained in the batteries. Extensive environmental sampling last summer identified a six-acre area of gross contamination (mainly lead). Later, a second area of contamination was discovered to the southwest, where the Village of Gilberts Public Works building is now located, west of the railroad tracks - this is known as the Tower Hill Road site.

Rail corrugation consists of undesirable periodic fluctuations in wear on railway track and costs the railway industry substantially for it's removal by regrinding. Much research has been performed on this problem, particularly over the past two decades, however, a reliable cure remains elusive for wear-type corrugations. Recently the growth behaviour of wear-type rail corrugation-has been investigated using theoretical and experimental models as part of the RailCRC Project (#18). A critical part of this work is the tuning and validation of these models via an extensive field testing program. Rail corrugations have been monitored for 2 years on sites throughout Australia. Measured rail surface profiles are used to determine corrugation growth rates on each site. Growth rates and other characteristics are compared with theoretical predictions from a computer model for validation. The results from several pertinent sites are presented and discussed.
