Last Updated: December, 2011
The one-acre Adams Plating site is located at 521 Rosemary Street on the west side of Lansing, Ingham County, Michigan. The site is located in a mixed commercial and residential block. The population density in the area of the site is approximately 1,800 people per square mile. All local residents and businesses near the site receive their water from the Lansing Township Water System. Located near the center of the site is the Adams Plating Company which is an active electroplating operation. The Adams Plating Company has been in operation since 1964 and primarily has been involved in chrome, nickel, and copper electroplating. Prior to 1980, wastewater from the Adams Plating Facility was discharged to an old clay tile drain system located next to the building. After 1980, wastewater was pretreated for chromium, tin, copper, nickel, zinc, and cyanide and discharged in the sanitary sewer. In July 1980, the old clay tile drain system was ruptured during construction activities 50 feet south of the building. Later that month, green water began to enter the basement of a house located about 50 feet to the west of the construction. Analyses of the green basement water indicated the presence of chromium at 130 to 150 parts per million (ppm). In October 1982, a subsurface collection drain was installed immediately north of the house to collect chromium-contaminated seepage from the broken tile drain and ground water and to send it to the pretreatment system. The primary problem at the site was chromium in soils.
The site is being addressed by a combination of EPA and potentially responsible party (PRP) actions, with oversight by the Michigan Department of Environmental Quality (MDEQ).
Threats and ContaminantsThe soil is contaminated with tetrachloroethylene, arsenic, and chromium. Inhalation of contaminated subsurface soil particles or accidental ingestion of contaminated soil poses a potential health threat.
The U.S. Environmental Protection Agency (U.S. EPA) proposed the site to the National Priorities List (NPL) in June 1988 and finalized the site on the NPL in March 1989.
U.S. EPA performed an investigation of the site from August 1988 through September 1993, after determining that the potentially responsible party (PRP) did not have the resources to perform the study. A final cleanup decision was reached in a September 1993 Record of Decision (ROD). The ROD called for excavation of soil contaminated with chromium and arsenic from around the buildings at the site and disposal of the contaminated soil in a solid waste landfill.
From September 1993 to September 1994, U.S. EPA performed the design and construction phases of the project. U.S. EPA performed the work after determining that the PRP did not have the necessary resources to perform the work. Approximately 5,400 cubic feet of soil was excavated from around buildings at the site. Soils assumed to be contaminated under the buildings were not removed because they were effectively isolated from the environment and human contact by the buildings' foundations. The contaminated soils under the buildings were also isolated from clean backfill by the vertical barriers. However, U.S. EPA acknowledged that if any buildings within the area affected by site-related contamination were abandoned or demolished in the future, options for remediation of contaminated soils under the building(s) would be evaluated by U.S. EPA.
A Preliminary Close Out Report (PCOR) was completed on September 30, 1994, and a Final Close Out Report (FCOR) was completed on September 28, 1995. O&M of the site has been conducted by the PRP, including semi-annual groundwater monitoring.
The first five-year review report for the Adam's Plating site was completed on October 7, 1999, and a second five-year review report was completed on June 27, 2005. Both five-year reviews concluded that the remedy selected in the ROD was implemented, remains functional, operational and effective, and continues to provide adequate protection of human health and environment.
The third five-year review for the Site was completed on June 25, 2010, and concluded that the remedy is protective of human health and the environment in the short term. The June 2010 review also noted that the monitoring program requires the evaluation of groundwater data, the contaminated glacial aquifer is vertically separated from the drinking water aquifer, and the continued maintenance of the warehouse and the APC building provide protection of human health and the environment. The five-year review report also noted that additional data collection and evaluation are necessary to ensure the remedy continues to be protective of the drinking water pathway and the vapor intrusion/indoor air pathway in the long term. Institutional controls (ICs) are required for this remedy. The existing IC on the Adam's Plating Company property will be reviewed and modified, as necessary, to ensure long term protectiveness. ICs on an adjacent property are still needed to prevent disturbance of contaminated soils beneath the warehouse building and to prevent exposure to contaminated groundwater and soils. The warehouse owner has expressed a willingness to record use restrictions on the property and MDEQ staff continues to work in that direction.
On December 27, 2010, a fire destroyed the Adams Plating facility. As a result of the fire the Site was re-contaminated with electroplating waste. U.S. EPA initiated a time-critical removal action at the Site to address the immediate threats posed by the electroplating wastes as a result of the fire, and the removal action was completed by December 2011. U.S. EPA has initiated a new Remedial Investigation and Feasibility Study (RI/FS) to determine if there is any remaining contamination that will need to be addressed at the site, and the RI/FS is currently in the project planning phase. The remedial investigation fieldwork is expected to start in the Summer of 2012.
