A response action was conducted in March of 2013, consisting of the excavation and removal of soils impacted with lead, copper and thallium. Excavated soils were taken off-site for recycling .
Confirmation samples collected from the various source areas demonstrated that impacted soils exceeding regulatory limits for Tl, Cu, and Pb were removed. Confirmation sampling verified that remaining in place soil concentrations were below Texas Risk Reduction Program Protective Concentration Levels. The removal action has been effective in removing impacted soil exceeding critical limits allowing the former industrial property to be developed for residential use.
