State of Illinois
Public Water Supplies
Annual Compliance Report
Calendar Year 2002
The purpose of this report is to satisfy the requirement of Section 1414(c)(3) of the 1996 Amendments
to the Safe Drinking Water Act (SDWA). States with national primary enforcement authority are to
prepare, make readily available to the public, and submit to the Administrator of the United States
Environmental Protection Agency (USEPA) by July 1 of each year, an annual report on violations
occurring during the previous calendar year of national primary drinking water regulations by public
water systems (PWSs) in Illinois. Attached is the Annual Compliance Report for Calendar Year 2002
(CY02).
Attached to this report as Appendix A is a listing for each contaminant regulated by the SDWA, the
numbers of maximum contaminant level (MCL), treatment technique (TT) and major monitoring and
reporting (M/R) violations for each compliance period during CY02 and the number of systems
incurring violations. Appendix B is a detailed listing of the MCL and TT violations.
In Illinois, oversight of PWSs is divided between the Illinois Environmental Protection Agency
(Illinois EPA) and the Illinois Department of Public Health (Illinois DPH). Illinois EPA has been
designated as the lead agency for primary enforcement authority and oversees the community water
supply program (those supplies that serve 25 or more year round residents). Illinois DPH oversees the
non-transient, noncommunity water supplies (NTNC) that serve 25 or more of the same nonresidents at
least 60 days out of the year and include facilities such as day care centers, schools and factories.
Illinois DPH also oversees the transient non-community (TNC) water supplies that serve 25 or more
different nonresidents at least 60 days out of the year and include facilities such as campgrounds and
highway rest areas.
The Illinois Safe Drinking Water Goal is for every Illinois Public Water system to provide water that is
consistently safe to drink. As a part of the its partnership agreement with USEPA, Illinois EPA
measures the environment progress of the drinking water program with environmental indicators
consisting of the percentage of persons served by community water supplies that have not incurred
violations of any acute MCL, chronic MCL, acute treatment technique, chronic treatment technique or
health advisory during the year for drinking water standards that have been in effect for more than
three years. The environmental objective of the Illinois EPA is to increase the percentage of
population served by community water supplies that receives drinking water with no short-term (acute)
or long-term (chronic) adverse health effects to over 95 percent by the year 2005. The progress
towards this objective is summarized on the following pages.
