Oxidation reagent injections

During the first week of November the first batch of the second round of oxidation reagent injections began in Zones G and H (6,000 liters), performing a test injection with previous washing.

In order to evaluate the efficacy of this new injection strategy with previous washing, water sampling was performed before and after injection of the washing solution (400 liters) in Zone G and H. TPH desorption is expected from the ground.

In all the boreholes on the site of La CLICA water table depth was measured in order to know the groundwater level.
