1. Arsenic Mass Balance: Florida

2. Purpose  Determine the relative magnitude of arsenic from CCA-treated wood versus the amounts from other arsenic sources  Evaluate arsenic inputs, outputs, and reservoirs

3. Inputs  CCA-treated Wood  MSMA (Monosodium Methylarsonate) a Herbicide/Pesticide  Coal and Petroleum  Biosolids from Wastewater Treatment  Fish and Shellfish  Rainfall and Rivers

4. Outputs  Fertilizer  Air Emissions from Incinerator Facilities  Treated Wastewater  River Outflow

5. Reservoirs  CCA-treated Wood  Groundwater  Surface Water  Surface Soil  Specific Contaminated Areas?
