SOUTH WEBSTER STREET

The Central Illinois Public Service Company site (CIPS) is located in Christian County, Illinois. The site is slightly less than one acre in size and is located in the city of Taylorville, a community of approximately 11,000 people. A manufactured gas plant operated on the site from 1892 until 1932. The coal gasification process produced a by-product called coal tar. Coal tar is a mixture of volatile organic compounds (VOCs) such as benzene, and polynuclear aromatic hydrocarbons (PAHs) like naphthalene and benzo(a)pyrene. As a result of operations, coal tar contaminated the soil, groundwater, surface water, and sediment around the site. Investigations identified a plume of contaminated groundwater migrated approximately 700 feet off-site. Nearly 500 residents within a one-mile radius of the site use the aquifer for potable water. Additional groundwater investigation indicated that four out of 22 homes were contaminated with compounds associated with coal tar.
