Background

Venice Park Recycling and Disposal Facility (RDF) is located at 9536 East Lennon Road. It is an active Type 2 municipal solid waste landfill operated by Waste Management, Inc. (WM) since 1993.  Prior to its acquisition by WM, groundwater contamination was discovered in monitor wells on the western side of the landfill. In 1991, a remedial investigation was undertaken which included residential well sampling. It was found that contamination was limited to the uppermost aquifer, and residential drinking water was unaffected. Due to historical contamination, in March 2019, EGLE requested WM sample select groundwater monitoring wells for PFAS analysis.

In the vicinity of the impacted groundwater monitoring well, groundwater flow direction in the uppermost aquifer is to the southwest. Some of this groundwater may discharge to Rush Creek, just south of the landfill.

Recent Accomplishments

  • On March 28, 2019, EGLE sent a letter to WM requesting PFAS sampling at select monitor wells at Venice Park RDF.
  • On November 11, 2019, WM’s consultant, Golder Associates, Inc., collected four groundwater samples from on-site monitoring wells. EGLE and Shiawassee County Health Department staff observed the event.
  • On February 12, 2020, EGLE received the results of the November sampling event. While multiple PFAS compounds were discovered in three monitoring wells, only PFOA in monitoring well MW-34S had a concentration exceeding the EGLE Part 201 criteria of 8 ppt. MW-34S had a concentration of 17 ppt PFOA and was non-detect for PFOS.

Next Steps

  • EGLE will begin discussion with WM to address PFAS contamination at the site.

Residential Well Testing/Alternate Water Information

  • EGLE is working with the local health department to review well logs.  Based on the known geology at this site it is unlikely that nearby residential wells are impacted.

Upcoming Community Engagement

  • None scheduled at this time.

*Residential well and groundwater monitoring well results are compared to EGLE Part 201 Criteria for 7 PFAS compounds: PFOS (16 ppt), PFOA (8 ppt), PFNA (6 ppt), PFHxS (51 ppt), PFHxA (400,000 ppt), PFBS (420 ppt), and HFPO-DA (370 ppt).

*Surface water samples are compared to Rule 57 non-drinking water values of 12 ppt for PFOS and 12,000 ppt for PFOA.
