The Gary Works Facility has been broken down into thirteen (13) Solid Water Management Areas (SWMA) in order to allow orderly investigation of the entire 4,000 acre facility. These SWMA's were designated to group process areas within Gary Works which would allow a focused investigation of similar chemicals of interest from like processes.

The SWMA's are listed below:

	East End		C-Lot Lagoons
	East Side Groundwater		Sheet and Tin Mill
	Buchanan Street Basins		Coke Plant
	West Side Groundwater		Iron Producing
