Vapor Intrusion

Vapor Intrusion

Certain chemicals that get spilled or discharged into the ground emit gases, or vapors, that can move through the soil.  These vapors may enter a house or building through cracks, holes, drains, and other small openings in a basement floor, wall, or foundation slab. This is called vapor intrusion.  It is similar to how radon, a naturally occurring gas, enters a house or building.

Common chemicals that have been found in vapor intrusion sites in Michigan include trichloroethylene (TCE, used often as a metal parts degreaser), tetrachloroethylene (PCE or Perc, used in dry cleaners), and benzene, toluene, ethylbenzene, xylene (BTEX, associated with gas stations).  The potential for health risks is dependent on the type and concentration of chemical or compound that is detected.  

The Livingston County Health Department (LCHD) is working collaboratively with the Michigan Department of Environmental Quality (MDEQ) and the Michigan Department of Health and Human Services (MDHHS) to evaluate the potential for indoor air quality health risks in areas with historical groundwater contamination sites. 

  ACO-Pittsfield Products Site

In 1974, the manufacturing company located at 461 North Dexter, Pinckney released TCE into storm and sanitary sewers causing ground water contamination in 20 residential drinking water wells. In 1992, these homes were connected to a municipal water supply and the wells were removed from use. ACO Pittsfield took responsibility for the contamination. They continue to work with MDEQ to remove TCE from drinking water. In July 2018, MDEQ started investigating vapor concentrations from indoor air and soil samples in the affected area.  For more information please click here.

 Holly Road Site

A former manufacturing company located north of Holly Road and Fifth Street in Brighton released chlorinated solvents in the environment, which contaminated the groundwater. The contamination plume is currently undergoing treatment by the MDEQ and extends approximately 2,500-feet south of this property. During the summer 2018, soil and indoor air samples from some homes in the affected area were tested for TCE vapors. For more information click here.

 Haigh Manufacturing Site

The former Haigh Manufacturing company on Whitmore Lake Road in Green Oak Township released TCE in the 1960's that contaminated the groundwater in this area.  The contamination was discovered in the 1990's. In 2004, the subdivision located south of the site was connected to the municipal water.  In May 2018 sampling of indoor air and soil gas began. For more information click herePlease note this is a map of the shallow groundwater contamination plume from 2005.  No homes in this area have wells in use.
