Superfund Site Profile


The Organic Chemicals Inc. (OCI) site is located about one mile southeast of the Grand River in Grandville. It was previously used for petroleum refining from 1941 to 1945 and for transport and storage operations from 1945 to 1966. A succession of petroleum-related industries leased the land, prior to its purchase by Spartan Chemicals in 1968. Spartan Chemical Co. reclaimed solvents and conducted chemical manufacturing operations of its subsidiary, Organic Chemicals Co.  OCI operated on the site from 1968 to 1991, and, in 1979, became the owner by a deed conveyance from Spartan.

Residential areas are about 200 feet southeast and 1,700 feet to the southwest of the site. All water is supplied by the city of Grandville although some residents use well water for lawn sprinkling. Between 1968 and 1980, company records indicate that OCI discharged its process waste and cooling water, which included hazardous wastes, into the on-site seepage lagoon. In 1980, the company installed a wastewater pre-treatment facility with discharge to the city's sanitary sewer system. 

The soil cleanup was completed in 2003 by excavating about 2,500 cubic yards of the contaminated soil and disposed of off-site. Contaminated water and sludge was removed from concrete tanks in 2006, and the tanks have been closed.

In 2010, EPA approved an enhanced bioremediation pilot study which injected a soy-based liquid underground to help naturally occurring bacteria break down any remaining groundwater contamination. Groundwater is sampled annually to make sure contamination is not traveling off-site.

A new owner developed the site as a truck parking center under Superfund’s reuse program.

Site Updates

September 2014

EPA completed a review of the site's cleanup. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment. 
The review included:

  • An evaluation of background information
  • Cleanup requirements
  • Effectiveness of the cleanup and any anticipated future actions
  • Maintenance and monitoring efforts
  • An analysis of ways for EPA to operate more efficiently

The review found the cleanup continues to protect people and the environment. Agreements are in place but need to be updated to make sure the property is used only for industrial purposes and to prevent groundwater from being used or the soil disturbed.  Although contamination in groundwater is declining, the cleanup will continue until goals are achieved. The next scheduled review will be in 2019.
