Zellar Residuals Management Area (Manistique, Schoolcraft County)

Background

Zellar Residuals Management Area is a closed landfill that was not licensed; it operated in the 1980s to the late 1990s. The landfill received paper pulp waste from Manistique Papers, Inc. (now U.P. Paper, LLC), which processed recycled paper. The landfill was not capped when it was closed. Paper pulp waste from this era often contained PFAS chemicals.  EGLE requested PFAS sampling of the Residuals Management Area because pulp waste is often high in PFAS chemicals, and the landfill is unlined and has had historical impacts to groundwater.

Groundwater flow is to the north-northeast and there are no downgradient residential drinking water wells.  There are several upgradient residential wells. A groundwater sample collected from an upgradient monitoring well was non-detect for PFAS. Gould's Slough and the Manistique River are downgradient from the landfill. A surface water sample was taken from Gould's Slough, with results of 9.2 ppt PFOA, which is below water quality standards.

Recent Accomplishments

  • On November 9, 2020, the Residuals Management Area consultant, Bittner Engineering, Inc., collected groundwater samples from monitoring wells OB-13 and MW-4R.  A surface water sample was also collected from Gould's Slough.
  • On December 14, 2020, EGLE received the results of the November 9, 2020, sampling event at the Residuals Management Area.  Upgradient monitoring well MW-4R was non-detect for PFAS.  Downgradient monitoring well OB-13's results included 72 ppt PFOS and 590 ppt FOA. Other PFAS analytes were detected in this sample, but there are no federal or state standards for these analytes. The surface water sample collected at Gould's Slough had 9.2 ppt PFOA, which is under the state surface water criteria.

Next Steps:

  • Zellar Residual Management Area will continue groundwater monitoring of the landfill.

Residential Well Testing/Alternate Water Information

  • No residential wells are downgradient of the landfill.

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 effective 12/21/2020:  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
