Research Project: In-Situ Arsenic Removal on Unsaturated Alluvium Project Number: 5310-61000-016-03
Project Type: Reimbursable

Start Date: Jun 02, 2011
End Date: Dec 31, 2013

Objective:
Conduct laboratory soil column studies, to determine the arsenic adsorption properties of sediments collected by the USGS from Antelope Valley CA.

Approach:
We will examine arsenic adsorption and transport for the different sediment texture and 2 pH values (7.5 and 8.5) and two arsenic concentrations (10 and 100 µg/L) of applied water. We will also evaluate computer model predictions based on comparison with experimental data.
