HDR to Lead Clean-Up, Potential Redevelopment of Michigan’s Harbor Island

The City of Grand Haven has selected HDR to lead a contaminant investigation, cleanup and potential redevelopment effort on Harbor Island, located on the Grand River on the west coast of Michigan, near Lake Michigan. 

For 100 years, the island has been used for a coal-fired power plant and disposal of municipal solid waste, dredge materials and coal ash. Concentrations of inorganic chemicals associated with coal ash and per- and polyfluoroalkyl substances, or PFAS, a diverse group of human-made chemicals used in a wide range of consumer and industrial products, have been detected in groundwater at the site. 

HDR will provide a range of services, including:

  • Coal combustion residuals, or CCR, compliance and investigation
  • PFAS compliance and investigation
  • CCR and PFAS remediation, which will consist of engineering consulting for solid waste and water treatment
  • Public engagement
  • Grant writing
  • Potential redevelopment

Our team will address these concerns holistically through environmental remediation, which requires specialized data collection and analysis. This project represents HDR’s first in Michigan with urban development planning, CCR and PFAS cleanup at the same site.
