Characterization of Arsenic concentrations in groundwater for effective planning and management of drinking well operations
- Start date: 2017
- End date: 2018
- Funded by: Lario Reti Holding S.p.A
- Topic: Development of an approach aimed at defining a groundwater flow and transport model leading to the quantification of the contamination risk of target pumping wells in the presence of uncertain aquifer parameters and geochemical process.
Arsenic (As) is a heavy metal typically found in natural environments as an inorganic molecule with oxydation states +5 (As(V)) or +3 (As(III)). European regulations set Arsenic concentration threshold to 10 µg /L for drinking purposes. In the province of Lecco, a higher concentration of As has been found in some drinking wells. This project aims at identifying possible natural/anthropic sources of arsenic at the basis of the high concentrations of As found in pumping wells.
