文摘
- •
High As concentrations (> 10 ppb) were measured in private bedrock wells
- •
The oxidation of As-bearing sulfides is the primary source of As in groundwater
- •
As(III) was the major As species in bedrock well waters
- •
As in bedrock wells originates from reducing chemically evolved groundwater
- •
Private well users are exposed to high As concentrations
