Comments/Observations/Problems: Illinois implements two phases of its program with a Phase I delineated area of 1000' and as necessary a Phase II delineation.
During the 1991-1995, the State took credit for its effort to identify sources and manage (using the provisions under the Illinois Groundwater Protection Act) within
the Phase I area. When 2 numbers are reported above for a step, the first number reflects the Phase II aspect and the second reflects the Phase I. For the 1997 report,
the State revised its tracking to reflect more locally-driven efforts. Any decrease in the total number of PWSs over the reporting periods may be due to regionalization of
systems or more accurate database tracking.
