Background

The 70-acre Yeoman Creek Landfill site is located in Waukegan, Illinois. A landfill operated on site from 1959 to 1969. The landfill has no bottom liner and the underlying soils are permeable. Polluted liquid from the landfill contains chemicals, elevated concentrations of metals and ammonia. Landfill gas was detected migrating off site. The site’s long-term remedy is in place. Study of landfill gas migration and groundwater monitoring are ongoing.

What Has Been Done to Clean Up the Site?

EPA is the lead agency in partnership with Illinois EPA overseeing the potentially responsible parties’ (PRPs’) cleanup of the site.

EPA has conducted several five-year reviews of the remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. Most issues identified during the 2007 five-year review have been addressed. The PRPs completed construction of a new perimeter trench gas collection system as well as drainage system improvements, grading and seeding in 2009. However, landfill gas on the northern portion adjacent to the site continues to be a problem and is being studied. Groundwater monitoring is ongoing.

What Is the Current Site Status?

The site is being addressed in two stages: immediate actions and a long-term phase focused on cleanup of the entire site. In 1980, the city upgraded the site cover in most areas of the landfill. The site’s potentially responsible parties fenced the site in 1990 and installed a ventilation system in a building next to the site in 1994. EPA selected the site’s long-term remedy in 1996. It included sediment collection in Yeoman Creek and limited wetland areas, reconstruction of Yeoman Creek, a flexible landfill cover, continuation of measures to address landfill gas, waste consolidation and extensive long-term monitoring. Remedy construction took place from 2002 to 2005.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup.

For more background, see Institutional Controls.

Contaminants of concern at the site include volatile organic compounds (VOC), polychlorinated biphenyls (PCB), bis(2-ethylhexyl)phthalate, and elevated concentrations of lead, manganese, iron, chloride, and ammonia.
