Determining resource quality and potential reasons for impairment of Illinois streams, inland lakes, and Lake Michigan : (Methods used for 2002 305(b) reporting).

According to Section 305(b) of the Clean Water Act (i.e. a generic name that refers to the Federal Water Pollution Control Act of 1972, the Clean Water Act of 1977, and subsequent amendments) and guidance provided by the United States Environmental Protection Agency (USEPA), each state must prepare and submit annually to the U.S. Congress and the USEPA report that describes the resource quality of the surface waters of the state. Every other year, this report, commonly referred to as the "305(b) report," must be provided in written form, whereas in alternate years each state may submit an electronic database to meet the reporting requirement. In the 305(b) report, states must also explain how they determined the resource quality of the waters of the state in terms of the degree to which predefined beneficial uses of those waters are supported. Also, in the 305(b) report when any designated use for any water body is not fully supported, the state must report potential reasons for the impairment. Herein, is explained how the Illinois Environmental Protection Agency determines the resource quality of Illinois streams, inland lakes, and Lake Michigan.

Groundwater contamination in McHenry, Illinois.

Soil contamination on the Elm Street site is located mainly underneath and near the building foundation. Groundwater contamination appears to extend beyond the property boundaries to the west towards the Fox River, which is approximately 1100 feet west of the site. The groundwater contamination is located in a mixed industrial, commercial and residential area. It is not clear at this point whether there may be multiple sources of contamination in the area. Currently the public water supply is only available to some properties along Route 120, where there is a water main in place. Most of the homes and businesses in the area use private wells for their water source.

Groundwater contamination site near former dry cleaner site : McHenry, Illinois /

Contamination in soil and groundwater was found during an investigation of a property located on the east side of the Fox River in McHenry, at 3004 W. Elm Street (Route 120) during 2003-2006. The property, currently owned by Inverse Investments, Inc., is enrolled in an Illinois Environmental Protection Agency (Illinois EPA) cleanup program. It is the location of a car rental establishment. Gem Cleaners occupied the site from 1970 to 1977, after which it was occupied by a carpet dealer, an automotive repair facility, and a tire store. Historic use of solvents at the former dry cleaner location has resulted in contamination of the soil and groundwater with chlorinated organic compounds.
