The Site is situated in a mixed residential and commercial section of the City of Wyoming that includes small industrial facilities. The City of Wyoming is a suburb of Grand Rapids which is located in west-central Michigan, approximately 25 miles east of Lake Michigan in Kent County. The Site is bordered by US 131 South, Cole Drain, a Consumer Powers substation, and several small industries. The Site encompasses a 2-acre parcel of land owned by Univar USA Inc. (formerly ChemCentral Corporation); a rectangular parcel owned by Consumers Power extending north from the ChemCentral (Univar USA Inc.) property with the approximate dimensions of 1,800 feet in length by 300 feet wide; Cole Drain a small urban creek flowing in a northerly direction and located along the Site's western boundary; and any property beyond the ChemCentral (Univar USA, Inc.) property boundaries where hazardous substances have come to be located. Hazardous substances have been identified in the soil and/or groundwater of nine (9) properties including the ChemCentral (Univar USA, Inc.) property.
The nearest residences to the Site are located approximately 500 feet west of the property boundary. The residential areas primarily consist of single family homes. There are two hotels located within approximately 800 feet of the Site. No one is currently using the groundwater down-gradient of the Site. One commercial well is located at the C.D. Osborn facility which is side-gradient to the Site.
The remedy for the Site included the following components: Continue operation of the existing groundwater collection and treatment system; install and operate a soil vapor extraction (SVE) system for soils on-property as well as two off-property locations just north of the ChemCentral (Univar USA, Inc.) property; install and operate a purge well at the deep lens of a contaminated groundwater location and hook this well into the current groundwater collection and treatment system; collect oil accumulating in the purge wells and dispose of the oil at an off-site facility in accordance with applicable federal and state regulations; install and operate an expansion of the current off-property groundwater collection system, by either extending the interceptor trench or installing additional purge wells; impose institutional controls (ICs), such as deed restrictions to prohibit the installation of water wells in the site area and any future development that might disturb contaminated soils; and implement a groundwater monitoring program capable of demonstrating the effectiveness of the groundwater capture system and that the groundwater treatment technology is achieving the cleanup standards. The Site achieved construction completion with the signing of the Preliminary Closeout Report on September 19, 1995.
The remedy is currently protective of human health and the environment in the short term because it eliminates the principal threat posed by the Site by preventing direct contact with contaminated materials through the groundwater collection and treatment system, the soil vapor extraction system, and groundwater monitoring program.
Site remediation upgrades beginning in 2009 included improvement and simplification to the pump and treat system. Modifications to pretreatment and system components resulted in more consistent operation. A bio-enhancement plan was submitted by ChemCentral (Univar USA, Inc.) to the agencies in 2009. It contained both aerobic and anaerobic components. The aerobic system was installed in 2011 and began operating in December of 2011. Groundwater conditions began to show improvement during 2012 and continued into 2013. While there are still exceedances to the cleanup goals set in the ROD, the general trend has been stable or decreasing. Bi-weekly (every other week) site visits are conducted to perform operation, maintenance and monitoring activities.

The Site’s fourth Five Year Review (FYR) was signed on November 7, 2014. The purpose of a FYR is to evaluate the implementation and performance of a remedy in order to determine if the remedy will continue to be protective of human health and the environment. The methods, findings, and conclusions of reviews are documented in five-year review reports. In addition, FYR reports identify issues found during the review, if any, and document recommendations to address them.
