Warner-Lambert Company LLC (Holland, Ottawa County)

EGLE Site Lead: Nicole Sanabria, or 517-281-7726. Webpage last updated July 7, 2021.


The site, located at 188 Howard Avenue, Holland, was formerly owned by Warner-Lambert Company, LLC, but was acquired by Pfizer, Inc., in 2000. It was primarily used for pharmaceutical manufacturing from 1951 to 2007 and cleanup has been ongoing at the site since 2000. As part of those cleanup efforts, a clay barrier wall was installed along the perimeter of the site to contain contaminants on-site, such as aromatic organics. In addition, groundwater is extracted, treated, and currently disposed of in on-site deep injection wells. The facility is evaluating alternative options for managing extracted groundwater. In support of that effort, a sample was collected from the groundwater extraction system and analyzed for PFAS in June 2020.

The site is located on the Macatawa River. Groundwater typically flows southeast toward the river, but the containment wall and groundwater extraction system keep groundwater from moving off-site.

*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).

Sampling Notes:

  • In June 2020, Pfizer collected a sample from the groundwater extraction system.
  • On August 31, 2020, EGLE received a report from Pfizer containing sample results collected form the on-site containment system. PFAS compounds above cleanup criteria included PENA at 1,900 ppt., and PFOA at 110 ppt.
  • On February 18, 2021, EGLE sent a letter to Pfizer requesting PFAS investigation be conducted on an off-site property located adjacent to the site.
