Treatments of the contaminated site recommended by the US EPA in 1993 are summarized as follows:  In the five-year review issued in August 2009, the EPA determined that the remedial actions have successfully contained on-site waste and blocked exposure pathways. The second five-year review report issued in September 2014 also stated that the remedy remains protective. The remedy is also effective in preventing direct exposure to contaminated soils. The next five-year review is scheduled to be released at 2019, since waste is left on site and WDI does not allow for unlimited use and unrestricted exposure.
