Community water supply well shooting/blasting near Hillcrest Subdivision, Lake County, Illinois.

The purpose of this fact sheet is to provide a summary of literature research on the use of well "shooting" or blasting technology in Northern Illinois. Water well shooting or blasting is done to increase water yield from a sandstone aquifer for a particular water supply well ... The Lake County Health Department (LCHD) detected a chemical, vinyl chloride -- from a family of chemicals known as volatile organic compounds (VOCs) -- in some private wells in the unincorporated Hillcrest Subdivision near Wauconda, through routine well testing done in the fall of 2003. The LCHD presented these findings to the public at a January 13, 2004 meeting. The concern was raised at the public meeting that recent subsurface water well "shooting" or blasting techniques, performed in the deep sandstone aquifer (800 to 1,000 feet below ground surface), in the borehole of a community water supply (CWS) well in the area, might have impacted the shallow aquifer in such a way as to contribute to private well contamination under investigation in the Hillcrest Subdivision.

Responsiveness summary : United States Army Corps of Engineers : Waukegan Harbor, Lake County, Illinois : Section 401 water quality certification for dredging of the Waukegan Harbor approach channel and advanced maintenance area.

The approved project allows the Corps to dredge the Waukegan Harbor approach channel and advanced maintenance area. The area to be dredged lies immediately east of the north breakwater. It is approximately a rectangle 650 feet north and south and 1,400 feet east and west. The advanced maintenance area is a band along the north side of the channel. The approved project is for a 10-year certification, under which the Corps may remove 22,000 to 75,000 cubic yards of sediment per dredging event. The dredging depth is 22 feet and the amount to be dredged is about one foot of sediment. As a condition of the certification, disposal of the dredged sediment in Lake Michigan or the waters of the state cannot occur until the conditions of the certification are met. These conditions, which have been placed on the certification by Illinois EPA, ensure that the project meets state water quality standards and is consistent with the determinations of the Illinois Attorney General's Task Force on asbestos contamination at Illinois Beach State Park.
