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?
