Filtration Required

Section 611 Section 611.211  Filtration Required The Agency must require a supplier using a surface water source or groundwater under the direct influence of surface water to filter the water it provides to the public. BOARD NOTE:  This Section originally derived from 40 CFR 141.71 and the preamble discussion at 54 Fed. Reg. 27505 (June 29, 1989). The Board replaced the original rule with the present requirement that a supplier apply filtration treatment because no supplier using a surface water source or groundwater under the direct influence of surface water operates in Illinois.  This rule avoids a gap in the Illinois rules.
