DeTray Plating Works
DeTray Plating Works, 10406 E. 11th St., Independence, MO, Jackson County.
On June 28, 2012 a fire occurred in Jackson Counuty at the DeTray Plating Works facility at 10406 E. 11th St. in Independence MO. As a result of the fire, chemicals used in the plating process were released to the environment. This webpage has been established to provide information to the public regarding the release and subsequent actions by the department and DeTray Plating Works to address resulting soil and water contamination.
The fire occurred on the evening of June 28, 2012. The Independence fire department responded quickly and used water to fight and eventually extinguish the fire. The fire destroyed the DeTray Plating Works, or DeTray facility, resulting in the release of chemicals used in the plating process. These plating chemicals contain high concentrations of certain metals, in particular trivalent and hexavalent chromium, nickel, arsenic, cadmium, copper and lead. Cyanide is also used in the plating process and was released to the environment along with the metals.
Water from the firefighting efforts caused the released plating chemicals to flow to a drainage ditch along the north side of the DeTray property. From the ditch, the water flowed into a culvert pipe near the northwest corner of the DeTray property. The culvert pipe leads directly to Crisp Lake.
Personnel with the department’s Environmental Emergency Response, or EER, program arrived at the DeTray facility on the morning of June 29. EER personnel immediately began working with representatives of DeTray to address the release of plating chemicals. Download a copy of EER’s Missouri Environmental Emergency Response Incident Report for the release and their response.
On June 29, city of Independence personnel, working under the direction of EER staff, built a dam between the culvert outfall and Crisp Lake to prevent further discharge of contaminated water into the lake. Water that collected behind the dam was pumped into plastic storage tanks and appropriately disposed of off the site.
Soil and water sampling conducted by the department and a contractor for DeTray show that plating chemicals reached Crisp Lake. Soil samples collected at the base of the culvert showed elevated concentrations of cadmium, nickel and cyanide. Water samples collected at the point at which water from firefighting efforts entered Crisp Lake showed elevated concentrations of cadmium, trivalent and hexavalent chromium, copper, lead, nickel and cyanide. A water sample collected at the outfall for Crisp Lake (across the lake from the culvert pipe inlet) showed only a slightly elevated concentration of cadmium.
EER personnel worked with DeTray to address soil contamination on and downstream of the DeTray property. These efforts included the excavation and off-site disposal of over 800 cubic yards of contaminated soil, cleaning of sediment from the culvert pipe and the collection and off-site disposal of contaminated water that collected behind the dam. In addition, DeTray installed a second dam at the northwest corner of their property to prevent water in the ditch on their property from flowing into the culvert pipe.
Both DeTray and the department have collected soil and water samples on the DeTray property, from the ditch on the west edge of the property, from the area at which the culvert pipe discharges to Crisp Lake and from the Lake itself. In addition, because the metals in the plating chemicals are also found naturally in the environment, the department also collected water and soil samples from Doutts Lake. Doutts Lake is nearby but was unaffected by the fire. The results of samples from Doutts Lake were used by the department to determine background, or naturally occurring, concentrations of metals in the area. The background concentrations then serve as a point of comparison for the data collected from Crisp Lake. The soil and water data from Crisp Lake were also compared to health-based standards routinely used by the department.
Comparisons of the data collected from the DeTray property and Crisp Lake were and continue to be used by the department to determine the need for cleanup of soil near Crisp Lake, of Crisp Lake itself and on the DeTray property. At this time, the department has not required DeTray to take any action to cleanup Crisp Lake itself, though the department has directed DeTray to clean up contaminated soil at the base of the culvert pipe. Data collection and analysis activities and associated data review to determine the need for further sampling and cleanup action are ongoing.
All soil and water data for this site can be found below under Data.
The department is aware of the concerns of residents who live near the DeTray facility and Crisp Lake regarding actual and potential contamination resulting from the fire. The department has distributed a letter, along with maps and sample data, to residents near facility and lake. Download a copy of the Crisp Lake letter with included maps and tabulated data.
The department has involved the Missouri Department of Health and Senior Services, or DHSS, for their assistance in the interpretation of sample data from properties near the DeTray facility. The department will continue to consult with DHSS to ensure contamination resulting from the fire does not pose a risk to residents in the vicinity.
The links below are to all currently available soil and water sample data from the DeTray property, Crisp Lake and Doutts Lake. Cleanup actions continue at the DeTray property. Therefore, samples collected prior to or during cleanup do not necessarily reflect current contaminant concentrations. Please review the most recent data to determine current concentrations of metals in soil and water.

The department’s EER staff continue to work with DeTray to investigate and cleanup soil contamination on the DeTray property. As of Aug. 22, 2012, EER personnel are waiting on results for samples collected on the DeTray property during the first weeks of August. The sample data will help EER staff determine whether additional soil removal on the DeTray property and from the ditch near the west property line is warranted.
DeTray Plating Works intends to enroll their property at 10406 E. 11th St. into the department’s Brownfields Voluntary Cleanup Program, or BVCP. As a participant in the BVCP, DeTray, with oversight from the department, will conduct additional investigations of their property to determine whether contaminants are present at concentrations warranting further cleanup. The BVCP requires all participants to comply with the department’s Risk-Based Corrective Action, or RBCA, rule and guidance in evaluating contamination present on a property.
During the week of Aug. 20, the department distributed information to residents who live near the DeTray facility and Crisp Lake. The department plans to continue to evaluate the effect of releases of contaminated water from firefighting efforts on the health of Crisp Lake.
The department will continue to update this webpage as information becomes available and to otherwise provide information to residents regarding the DeTray site. Should you have questions, please contact one of the following:
