City of Manistee Former Landfill (Manistee, Manistee County)

EGLE Site Lead: Kaitlyn Bertram, BertramK@Michigan.gov. Webpage last updated July 20, 2021.

Background

The city of Manistee former Landfill is approximately 40 acres in size and is located on Adamczak Road about one-half mile east of Maple Road.  A Baseline Environmental Assessment (BEA) was submitted for a 3.82- acre parcel of vacant land on the former landfill.  A BEA is a tool that can be used to assess environmental issues on a property before a new buyer purchases that property.  As a part of the BEA on-site investigation, an existing monitoring well (LW-5) was sampled for PFAS due to the historical use of the property. This sample contained PFOA and PFOS above drinking water standards.  This sample lacked quality control and quality assurance data, so EGLE resampled the monitoring well and confirmed the presence of PFOA and PFOS above the drinking water standard. Note that monitoring, well LW-5, is screened approximately 40 feet below the water table and 80 feet below the ground surface.

Groundwater flow direction is currently unknown.  Manistee Lake is located approximately ¾ of a mile to the east/northeast; Lake Michigan is located approximately 2 miles to the west; and the Manistee River (2 miles), Lake Winnogene (1 mile), and Gambs Lake (1/2 mile) to the north of the site.

Based on available information, there are nearby residential wells surrounding this site.

Recent Accomplishments

  • During the week of April 19, 2021, three monitoring wells were installed at the site and groundwater was determined to flow to the northwest. Groundwater sample results were received, and a final report is pending.
  • On May 7, 2021 EGLE received the results of the monitoring wells that were installed at the site.

Next Steps

  • Part of EGLE's next steps will be to conduct a liability analysis and follow up with any liable parties identified.

Residential Well Testing/Alternate Water Information

  • MDHHS and District 10 Health Department are evaluating residential wells downgradient of the site.
  • One residential well, located ½ mile downgradient of the site was sampled. The results were below detection limits.

Upcoming Community Engagement

  • None scheduled at this time.

Sampling Results Summary

This table reflects data received after August 3, 2020. Data prior to August 3, 2020 is reflected in the timeline below.

This table was updated to include all seven PFAS criteria effective December 21, 2020.

* 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.

Sampling Notes

  • On August 3, 2020, new Part 201 Criteria went into effect.  Historical sampling data compared to Part 201 Criteria >70 is captured in the historical timeline below. 

Historical Timeline

    • On February 28, 2020, EGLE received the results for the sample collected.  The result was 310 ppt for PFOS + PFOA. 
    • Historical Sampling Chart: Data is reflective of criteria prior to August 3, 2020,  PFOS and PFOA Only

    • On August 27, 2020, EGLE arrived on site to begin vertical profiling of the aquifer to better understand the vertical distribution of PFAS in the groundwater. The drill rig broke down after completion of the first soil boring (VAS-1).
    • On September 28, 2020, EGLE received the analytical results for VAS-1, result indicated on the sampling chart below.
    • During the week of October 5, 2020 EGLE remobilized to the site to complete the additional two VAS borings. The drill was only able to advance the 2nd boring to about 100' below ground surface due to the fine nature of the sands they were drilling through. The sampling pump also burned out and they had to demobilize from site and thus were unable to complete the third VAS boring.
    • On December 10, 2020, EGLE received the results from VAS-2, result indicated on the sampling chart.
