Your Local Environment

A wide range of information is available from Illinois EPA and others to help you learn more about the environmental conditions in your community. On this page, we’ve provided links to databases and other information about pollutants that may affect the environment.

Right to Know

The Right to Know law requires Illinois EPA to notify citizens when contamination in soil or groundwater poses a threat of exposure to the public.

Conditions Overview

With U.S. EPA’s Window to My Environment, use interactive maps and tools to learn about environmental conditions, pollution sources, and watersheds in your community.

Air Quality

Daily Air Quality Report

This air quality index reports daily air quality for five major air pollutants: ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen oxide.

Annual Air Quality Report

This report highlights information obtained from the statewide air monitoring network, which incorporates more than 300 monitors that track the measurements of a variety of pollutants and air toxic compounds.

Land

Land Cleanups

Search these remediation databases to learn about remediation activities in your community. You can also view a map of sites that are part of the Voluntary Site Remediation program or the Leaking Underground Storage Tank (LUST) Site Remediation program.

Solid Waste Permits

Use this database to learn about permit applications submitted and permits granted for the management of non-hazardous waste at landfills, transfer stations, compost, and waste storage, treatment, processing, and recovery facilities.

Landfill Capacity Report

This report provides information about landfill disposal and available landfill capacity in Illinois, describes the management of nonhazardous municipal solid waste by the state's solid waste landfills and transfer stations, and includes lists of solid waste landfills.

Water Quality

Drinking Water

Drinking Water Watch - Local government officials and citizens can access information on the quality of the sources of public drinking water supplies and the quality of finished water coming out of the tap at this drinking water web portal.

Public Water Supply Annual Compliance Report - To satisfy the requirement of the Safe Drinking Water Act, Illinois EPA must prepare, make readily available to the public, and submit to the U.S. Environmental Protection Agency, an annual report on violations of national primary drinking water regulations.

Source Water Assessment and Protection (SWAP) The purpose of SWAP is to identify areas that supply drinking water to the public, inventory potential sources of contamination, determine the susceptibility of the source water to contamination, and inform the public of the assessment results. This site contains fact sheets on source water (wells drawing from groundwater, lakes and streams) for community water supplies and more detailed secure information for local government officials, environmental consultants, and municipal planners.

 

Rivers, Streams, Lakes and Groundwater

Water Resource Assessments - Data on rivers and streams, inland lakes, Lake Michigan, and groundwater are collected annually and water quality conditions are assessed. Results of these assessments are available in a comprehensive Illinois Water Quality Report and an associated Illinois Water Quality Information Mapping Tool; a summary of Condition of Illinois Water Resources reports; and various maps and graphs.

Total Maximum Daily Load (TMDL) - TMDLs, required by the Clean Water Act, are calculations of the maximum amount of a pollutant that a water body can receive and still meet water quality standards. Illinois EPA encourages public participation as it develops TMDLs for all impaired water bodies in the state.

 

Pollution Sources

Envirofacts - This website provides access to several U.S. EPA databases containing information about environmental activities that may affect air, water, and land anywhere in the United States.

Freedom of Information Act (FOIA) - Information about FOIA rules and procedures to request public information from Illinois EPA are available at this web page.
