In central and south Florida, strong housing demand and a limited supply of urban land has increased the residential development of former agricultural lands. At a former 14-acre ornamental nursery site, historical use of arsenical herbicides and pesticides contaminated soil and groundwater to levels exceeding residential cleanup goals. In 2003, a site assessment identified the extent of soil and groundwater with arsenic concentrations greater than regulatory cleanup goals. The direct exposure soil cleanup target level for residential property use is 2.1 mg/kg. A leachability study established a site-specific leachability soil cleanup goal of 12 mg/kg. The groundwater cleanup goal for the site is 0.05 mg/l.
