RE:
Docket No. R-04-021
Revisions to Radium Water Quality Standards
Dear Ms. Gunn:
The Village of Minooka, Grundy, Kendall and Will Counties, Illinois owns and operates a
Public Water Supply currently consisting of two deep sandstone wells (Wells No. 3 and 4)
and two shallow sand and gravel wells (Wells No. 6 and 7). The Village is currently under
contract to complete the construction of two additional deep sandstone wells, Water Wells
No. 8 and 9. The deep sandstone wells exceed the current combined radium potable water
standard of 5.0 pCi/I.
Water from Wells No. 3 and 4 is blended with water from Wells No. 6 and 7 to maintain the
radium to below drinking water standards. The Village of Minooka has selected the cation
exchange treatment process to remove the combined radium to below drinking water
standards from Wells No. 8 and 9. Construction for Well No. 8 has commenced and the well
and Well No. .8 Water Treatment Plant are projected to be complete and in operation in the
fall of 2005. The design for Well No. 9 and the Well No. 9 Water Treatment Plant is currently
in progress and these facilities are expected to be in service in the spring of 2006.
The cation exchange treatment process requires that the cations, including radium, removed
from the water during treatment be discharged to the sanitary sewer system. The Village of
Minooka sanitary sewer system is serviced by a Village owned and operated wastewater
treatment facility (WWTF). Since the WWTF has a discharge to the DuPage River, and
because the discharge has substantial dilution with the DuPage River, it is not anticipated
that there will be difficulty meeting the existing water quality standard of 1.0 pCi/I for radium

226. However, enforcement of the overly restrictive water quality standard could result in an
occasional violation and require additional expenditure of public funds without an associated
benefit to the public or aquatic and riparian life associated with the stream. Therefore, the
Village of Minooka supports the approval of the proposal to implement revised water quality
standards for radium concentrations in the receiving stream.
The Village of Minooka appreciates the opportunity to provide comments to the Illinois
Pollution Control Board on this important issue to our community.
