Brighton Township Dump located on Corlett Drive is a historic dump that accepted wastes during the 1960s and into the early 1970s.  The dump was closed in 1973 without covering or removing wastes.  In 1990, the U.S. Environmental Protection Agency (EPA) removed approximately 200 drums and 450 cubic yards of visibly contaminated soil from a ravine-pit near the center of the facility.  In 1996, monitoring wells were installed using state funds.  In 2002, the State of Michigan removed highly contaminated soil bordering the south wetland.  In 2009, the State of Michigan and Brighton Township entered into a consent decree.  Brighton Township agreed to pay a portion of past costs incurred by the State of Michigan in exchange for conducting response activities at the dump that included methane monitoring, monitoring well groundwater sampling and annual sampling of residential wells near the dump for a 10-year period if performance objectives were met. The consent decree did not provide for conducting response activities to address emerging contaminants such as PFAS.

Brighton Township agreed to extend the sampling period in 2019 to evaluate volatile organic compound contamination that was found to have entered an adjacent property.  On May 14, 2020, five monitoring wells were sampled by Brighton Township's consultant for volatile organic compounds only.  EGLE staff collected groundwater samples for PFAS analysis.  The sampled monitoring wells are near the wetlands and the residential well on the adjacent property.

There are nine residential wells surrounding the landfill, one of which is near two monitoring wells (one shallow and one deep) where PFOA and PFOS were detected. Brighton Township's consultant sampled the one residential well for VOC's and the result was non-detect.    

Groundwater flows to the northwest, and seasonally, in the southeast corner of the landfill, flows to the east.

Recent Accomplishments

  • In early September 2020, a geologic review was completed to determine which additional monitor wells at the former landfill should be sampled.
  • In October 2020, EGLE staff collected PFAS groundwater samples from 19 monitoring wells and five previously sampled monitoring wells.  
  • On November 6, 2020, EGLE received the results and reviewed for data validation and quality control measures.  The highest result was 170 ppt PFOS.  The results were shared with Livingston County Health Department (LCHD), DHHS and consent decree parties.
  • On January 25, 2021, EGLE began working with DHHS and LCHD to review surrounding residential well logs to determine which wells should be sampled for PFAS. 
  • On April 19, 2021, EGLE provided new notification to Brighton Township of its responsibility to address PFAS contamination not specifically covered in the existing consent decree. 
  • On May 3, 2021, Brighton Township notified EGLE that they would not commit to completing the proposed PFAS investigation work.
  • On May 20, 2021, EGLE staff went door to door to the sixteen residents selected for residential well sampling to seek permission by way of a signed access agreement to sample wells.
  • On May 27, 2021, MPART held a virtual town hall meeting to discuss the status of the site investigation.

Next Steps

  • EGLE's consultant will conduct residential well sampling at homes that grant permission in the late Spring 2021.  
  • EGLE staff will collect surface water samples from the wetland/pond next to the site in summer of 2021.
  • Monitoring wells at the dump will be sampled in Fall 2020.

Residential Well Testing/Alternate Water Information

  • Residential wells draw water from sand and gravel deposits and are deeper than the monitoring wells.  Clay layers identified in well logs may be protective of the aquifer where potable wells are set.  EGLE is working with local health department.

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).

Sampling Notes

  • On May 14, 2020, EGLE staff collected groundwater samples for PFAS analysis from five monitoring wells located near the southeast corner of the facility.
  • On July 1, 2020, a final PFAS analytical report was issued to EGLE.  PFOA and PFOS were detected in the five monitoring wells EGLE sampled.  The highest concentration of PFOA was 26 ppt and the highest concentration of PFOS was 18 ppt, both of which exceed the Part 201 criteria.  The highest concentration of combined PFAS was 110.4 ppt.  A geologic review was in progress to determine which monitoring wells should be sampled for PFAS by EGLE as part of the next phase of the investigation.  
  • On July 21, 2020, the consultant for Brighton Township sent EGLE sampling results to a homeowner with a residential well near two monitoring wells where PFAS was detected.  Livingston County Health Department was informed of the results, which were non-detect.
