Arsenic Mass Balance: Florida
Purpose
Determine the relative magnitude of arsenic from CCA-treated wood versus the amounts from other arsenic sources
Evaluate arsenic inputs, outputs, and reservoirs
Inputs CCA-treated Wood MSMA (Monosodium Methylarsonate)
a Herbicide/Pesticide Coal and Petroleum Biosolids from Wastewater Treatment Fish and Shellfish Rainfall and Rivers
Outputs Fertilizer Air Emissions from Incinerator Facilities Treated Wastewater River Outflow
Reservoirs CCA-treated Wood Groundwater Surface Water Surface Soil Specific Contaminated Areas?
