Pitsch Sanitary Landfill Sample Result Map Jan 2020Background

Pitsch Sanitary Landfill (PSL) is an active type II municipal landfill located at 7905 Johnson Road.  It is privately owned and operated by Pitsch Companies. Groundwater has been impacted by chlorinated Volatile Organic Compounds (VOCs) above drinking water standards and ground water/surface water interface standards. The source of the VOCs is thought to be from the historic township dump (which has been removed) and/or the unlined portion of the landfill. Monitoring is conducted quarterly to ensure the VOC plume is not expanding. Because of its historical VOC release to the environment, a potential release of PFAS was also of concern.  Results from groundwater sampling done in March 2019 included one well that exceeded groundwater cleanup criteria. Groundwater in both the shallow and deep aquifers eventually vent to the Flat River, which is a potential surface water receptor.

Recent Accomplishments

  • January 6, 2020, PSL submitted results for 3 additional groundwater monitoring wells.  One monitoring well was above the groundwater cleanup criteria.

Next Steps

  • Additional investigation is warranted in the OW-11 area, data will be reviewed, and a sampling plan formulated.

Residential Well Testing/Alternate Water Information

  • Most drinking water wells near PSL are installed in the deep aquifer and are side gradient to the landfill, outside of the area currently impacted by chlorinated VOCs.
  • Currently, there is no evidence that PFAS is leaving the site above groundwater quality standards.

Upcoming Community Engagement

  • None scheduled at this time.
Sampling: PFOS and PFOA Only

Pitsch Sanitary Landfill Historical Timeline

Pitsch Sanitary Landfill (PSL) is an active type II municipal landfill located at 7905 Johnson Road privately owned and operated by Pitsch Companies. Groundwater has been impacted by chlorinated Volatile Organic Compounds (VOCs) above drinking water standards and ground water/surface water interface standards. The source of the VOCs is thought to be from the historic township dump (which has been removed) and/or the unlined portion of the landfill. Monitoring is conducted quarterly to ensure the VOC plume is not expanding. Because of its historical VOC release to the environment, a potential release of PFAS was also of concern.

  • June 5, 2018 PSLs leachate was tested for PFAS by the Industrial Pretreatment Program initiative.
  • March 20, 2019 PSL sampled five onsite monitoring wells to assess PFAS in groundwater.  Results included one monitoring well that exceeded groundwater cleanup criteria.   
  • March 28, 2019, EGLE sampled three additional monitoring wells because of additional concern of potential impact to nearby receptors.
  • June 21, 2019 PSL sampled three additional monitoring wells to further assess PFAS in groundwater.
  • On September 26, 2019 EGLE and PSL met to discuss the need to continue to delineate PFAS impacts to groundwater.  PSL committed to sampling three additional groundwater monitoring wells. 
  • October 8, 2019, PSL submitted a workplan to sample 3 additional groundwater monitoring wells for PFAS to better define PFAS impacts in the shallow aquifer.  The workplan was approved by EGLE and samples were collected on December 11, 2019.
