Boca Raton (Fla)

Arsenic is a known carcinogen, but is persistent in the environment, remaining a popular pesticide. It represents a particular hazard to humans when it stays resident in shallow soils and groundwater. This study of contaminant hydrogeology examined conditions at a former golf course in Florida with known arsenic contamination, and included a detailed examination of existing assessment data for the study area, an experimental pumping test with groundwater sampling, examination of sediment cores, and a preliminary geophysical investigation. The primary purpose was to determine what the existing controls are on As mobility. The primary findings were that redox conditions did have an effect on As concentrations. Groundwater in the study area is generally reducing, but during the pumping test was generally oxidizing. No potential As sources were definitively identified, and the most likely source remains anthropogenic, but interactive conditions with Fe, Mn, NO3-N, and S remain nebulous.

The purpose of this study was to determine what budgetary
costs and revenues the City of Boca Raton would incur if
municipal jurisdiction and services were extended to a
10,100 acre tract of land located to the west of the city.
The projections of costs and revenues were made for both
the present level of development and for the area at full
development. The conclusion of the study is that should
annexation occur, revenues from the Reserve Area would
equal or exceed the costs of providing municipal services
at both levels of development. Early annexation would
result in increased revenues from construction related
permits and fees.
