Former Four Star Property (South Haven, Van Buren County)

EGLE Site Lead: Rachel Golota, GolataR@Michigan.gov or 269-370-2404. Content last updated January 13, 2023.

Background

The Former Four Star Property is located at 1391 Kalamazoo Street and operated as a nickel plating facility used for decorative automobile trim under various ownership from 1964 until 1983, including the Four Star Company. Previous investigations and remediation at the site were funded by the Brownfield Redevelopment and Financing Act. These activities abruptly stopped in 2005 when the property was split and sold. The site was evaluated by EGLE in June 2022 as part of a pilot study to reduce the number of locations where we haven’t determined the risk. The Former Four Star Property was sampled for PFAS in the fall of 2022 due to the probable use of PFAS in the plating manufacturing process.

Groundwater generally flows to the west towards Lake Michigan. Several storm sewer catch basins on and near the property flow into an unnamed creek. The creek travels approximately ¾ mile through South Haven’s industrial subdivision into a residential neighborhood and ultimately flows into Lake Michigan.

Recent Accomplishments

  • The week of October 31, 2022, EGLE collected one surface water sample, eleven groundwater samples and twelve soil samples at the Former Four Star Property.
  • On November 15, 2022, EGLE received the sampling results.  Eight of 11 groundwater samples exceeded criteria.  The highest result was 3,100 ppt PFOS (compared to 16 ppt), 160 ppt PFOA (compared to 8 ppt), and 1,700 ppt PFHxS (compared to 51 ppt).  The surface water result collected from the unnamed creek exceeded criteria.  The result was 51 ppt for PFOS (compared to 12 ppt).  

Next Steps

  • DHHS and the local health department are evaluating nearby residential wells to determine if any sampling is needed.
  • EGLE will hire a contractor to develop a plan to delineate the nature and extent of contamination in soil and groundwater beginning the spring of 2023. The investigation will include installation of groundwater monitoring wells, groundwater sampling, storm sewer sampling, and surface water sampling.

Residential Well Sampling / Alternative Water Information

  • The Former Four Star Property is located within the industrial subdivision of South Haven and municipal water is available. The closest residential drinking water wells are located approximately ¼ mile northeast of the property. EGLE, the Department of Health and Human Services (DHHS) and the local health department are evaluating nearby residential wells to determine if any sampling is needed.

* 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, 170 ppt for PFOA, and 670,000 ppt for PFBS.
